See who just joined your club
On the Roster, a student who joins your club with the join link or an email invite gets a green New beside their name for 7 days, and the line above the list says how many joined in the past 7 days. Hover over New to see the day they joined.

Clearer, steadier Coach pages and Moderate
After a check of every coach page and Moderate: recording a practice no longer takes a buzz on a bonus already recorded, keeps players who are away when you move a name, keeps team moves and Undo across a reload, and keeps seats in order if you tap Mirror twice. The same things now have the same names everywhere (club, Owner, Cancel, Nobody buzzed, past 4 weeks), the practice list counts what the practice page counts, buttons are easier to tap on a phone, and Help lists every Moderate key.

Your clubs lists the clubs you coach
For a coach, Your clubs now starts with the clubs you coach, each with Open club and Record a practice, instead of saying you are not in a club. Clubs you play in, and invitations, are still there.
Open Your clubs - ImprovedCoaches & moderators
Each club opens on an Overview
Open club now lands on Overview: the club's card from the Coach page in full, with every subject at practice and on their own. On the Coach page, each part of a club's card opens its tab, and Students has a This week column, so the two say the same thing. A practice you started and left without a toss-up no longer counts.
Open the Coach page - FixedCoaches & moderators
Record a practice opens the recording setup
After Record a practice on the Coach page, choosing a set and a round now opens the recording setup over the first question, with your club already chosen. Before, nothing asked you to record: the setup waited behind Record at the top of the round.
Open the Coach page - NewCoaches & moderators
Students and Topics for team A or team B
When some of your players are on team A or team B, a club's Students and Topics tabs let you look at one team: Everyone, Team A or Team B above the table. See where your A team is weak before a tournament. Still don't get it stays the whole club's, so marks stay anonymous.
Open the Coach page - ImprovedCoaches & moderators
Say who came before you record a practice
When you record a practice, tap the names of anyone not there under Who's here, and the recording strip shows only the players in the room. Someone came late? Press Recording at the top of the round and tap their name.
How recording works - ImprovedEveryone
School logos
A club that belongs to PRISMS, Princeton Middle School or Princeton Charter School now shows its school's logo: beside the club's name on the Coach page and Your clubs, when you join, and on the join screen shown in the room. The school badge by a player's or coach's name shows it too.
See Your clubs - ImprovedEveryone
Clubs, with team A and team B inside them
What a coach runs is now called a club: everyone they coach at one school, with its roster, co-coaches and practices. Players join a club once, and find it on Your clubs. Inside a club, players can be on team A or team B, like the two teams a school sends to a tournament, and each practice is played all together or A vs B. Only the words changed: every roster, practice and link is where it was.
How clubs work - ImprovedEveryone
Every item in the menu shows its name
The bar at the top of each page now shows every item's name under its icon, on a laptop too: Practice, Moderate, Review, Stats, Help, Theme, Your clubs, your own name and Sign out. You no longer have to hover over an icon to learn what it opens. On a narrower screen the menu button lists them all, each with its name.

Recording a practice: fewer taps, and players moved by dragging
In Moderate's recording strip, hold a player's name until it lifts and drag it to where they sit, or onto the other side. Side A stays on the left and B on the right; only Mirror swaps them. On a phone every name now fits, Nobody sits beside the question number, and a hint says how to move a player. When a team earns a bonus, the bonus opens by itself. Undo goes back more than one tap, says what it took back, and works even right after you mark a buzz early. Finishing an A vs B practice shows the final score. A practice you come back to hours later asks whether to finish it or keep adding, and one started by mistake can be deleted while it has no buzzes.
Open Moderate - FixedCoaches & moderators
Clearer practice results
A practice's results now list the players who buzzed, with one line for everyone who did not, so a big roster no longer fills the page with empty rows. Coverage gaps no longer counts a bonus nobody took as a second unanswered toss-up, and a middle school round is always called a Middle School round.
Open the Coach page - FixedCoaches & moderators
The A vs B score, live as you record
Recording an A vs B practice in Moderate, the score now shows at the top of the recording strip, and the line under it says what each tap added. It is the same score the practice's page shows. A bonus now counts for the side that won its toss-up, even after you open it; before, opening the bonus lost the side. A bonus read after a toss-up nobody got counts for neither side. A one-squad practice shows no score.
Open Moderate - ImprovedCoaches & moderators
Questions open in Moderate for your team
On Still don't get it and a student's record, a question's round now opens in Moderate for that team, ready to read and record without choosing the team again.
Open Coach - ImprovedCoaches & moderators
Everything about a team on the team's page
Each team now has one home: open it from the Coach page. A recorded practice opens inside its team, with the team's tabs still there, and New team has its own page. The separate Teams and rosters and Practice log lists are gone; their old links take you to the Coach page. On the Roster tab, Add players comes first, and each name is listed once and says whether it is linked to the student's account, invited, or has no account yet, with that name's invite link right beside it. Invite by email and the join link sit under Invite players, which folds away once every player is linked. Then Coaches, then the team's name and Delete team.
Open the Coach page - ImprovedEveryone
Faster pages
Practice, Moderate, set pages and the Coach pages open faster, and question loading fails far less often. Nothing to change on your side.
- ImprovedCoaches & moderators
A simpler Coach page
A team now opens on its Students tab, and Roster is the last tab: press Open team on the Coach page, or the team's name. Your team is shown with its school wherever it appears, and Record a practice opens Moderate on the rounds your school plays, so a middle school team gets middle school sets. Moderate opened for a team has a Back link to it. A team with no recorded practice yet no longer shows empty practice columns. In the recording dialog, Edit roster opens the team's roster in a new tab, so you keep your place in the round. Each thing has one name: Moderate, Practices, Students, A vs B, Finish round and Finish practice.
Open the Coach page - ImprovedCoaches & moderators
One team for your whole club
Making a new team now shows the teams your school already has, and who coaches each, so you can ask to be added as a co-coach and keep your players and practices in one place. One team is enough for a whole club: to play A against B, choose sides when you start a practice. A second team is for a separate program, such as middle school and high school. Help says the same under Make a team.
Open New team - ImprovedCoaches & moderators
A Students tab you can sort, and right means checked
On a team's Students tab, days practised now read like "4 of 6": the days a player practised in the past 28, out of the days since they joined the site. Click any column heading to sort by it (name, days, answers, right, or a subject), and Seating order puts it back; a sorted table keeps its order when you share the link. The Right column counts only answers the site checked: flashcards a player marks themselves still count as practice, but no longer as right or wrong, on the Students tab, each player's page and Topics. The player's name stays in view as the table scrolls, and small subjects share one Other subjects column.
Open the Coach page - NewCoaches & moderators
A step-by-step start for new coaches
The Coach page now has a Getting started list: make a team, add your players' accounts, record a practice, finish it and read the results, and add a co-coach. Each step ticks itself and takes you to where it happens, and Help has a full coach guide (For coaches, at the top of Help). Record a practice on a team's page now opens the reader with that team chosen, and the recording strip has a Finish button, on phones too. Each player's invite link is shown so you can check it, a link at the top of the Roster takes you to co-coaches and handing over, and the Discuss tab is now called Still don't get it.
Open the Coach page - ImprovedCoaches & moderators
Recording you can trust, and fewer surprises on the Roster
Buzzes that can't be sent now stay on your device with the reason (for example, if you were taken off the team), and Finish tells you what hasn't been saved yet. Removing a co-coach, merging two names, and making a new join link or turning it off now ask first and say what happened. Accepting a co-coach invite takes you to the team, and co-coaches no longer see the owner's usual practice as their own.
Open the Coach page - ImprovedStudents
Review drills what you missed, and practice opens on your level
Review now drills the questions you actually missed or rated Kinda. Quiz, Flashcard, Speed and Timed open on your level with 25 questions from anywhere on the site. Signed in, the top bar has a Your teams link; signed out, Sign up sits beside Sign In and the end of a practice offers to save it to an account. Sign-in links bring you back to the page you were on, and the site says Not saved when your avatar, weekly goal or level could not be saved.
Start practicing - NewStudents
Forgot your password? Reset it from the sign-in page
Sign in now has a Forgot password? link. Enter your email and we send a link to choose a new password. New passwords need at least 8 characters, the same on sign-up, Profile and the reset page. New accounts are also asked once what name to show on the site, with a suggestion filled in that you can change. Skip, and no name is saved for you; leaderboards show you as Anonymous until you set one on Profile.
Reset a password - ImprovedCoaches & moderators
Email invites no longer say who has an account
When you invite a student or a co-coach by email, the site now gives the same answer for every address: if that address has an account, they'll see the invite on their Your teams page. It no longer says whether an account exists or shows the person's name. Your waiting invites list the addresses you typed. For a student who may not have an account yet, send the invite link for their name instead.
Open your teams - ImprovedCoaches & moderators
Sharing a practice says what the link shows first
Share with the team now explains, before it makes the link, exactly what the link shows: the practice, and the names of the players who buzzed in it. Anyone with the link can open it, so a shared practice no longer lists players who did not buzz, who have left the team, or who joined later. Your own view of the practice still shows your whole roster.
Open the Coach page - FixedStudents
Signing out now clears a shared computer
On a shared computer, the next person could see your Review and Stats after you signed out, and if they then signed in, your answers could be saved to their account. Now Sign out saves your answers to your account first, then clears them from that computer, so the next person starts fresh. Your bookmarks and flashcard ratings are saved to your account too, so they come back when you sign in again, on any device.

Sides you choose before a match now stick
If you put a new player on side A or B just before starting an A vs B practice, they came back on neither side and their buzzes counted for no team. They now stay where you put them. Students signing up with Google also no longer get a pop-up over the Join button, and the Topics tab folds each subject so it fits on a phone.
Open the Coach page - NewCoaches & moderators
See where your team is weak, topic by topic
Each team has a new Topics tab. It goes below the subject to topics like electrochemistry or orbital mechanics, from what you recorded at practice and what linked players do on their own, and lists what to work on first. It counts how many players are struggling with a topic, and never ranks them.
Open the Coach page - NewCoaches & moderators
One page for each team
Open a team from the Coach page and everything is under one roof: Roster, Practices, Students and Discuss. On the Roster tab you can invite a co-coach, take one off, or hand the team to a co-coach if you step away. If you coach but have no coach account yet, ask for one from the Coach page.
Open the Coach page - NewStudents
See what your coach sees
On Your teams, each team now has a What your coach sees page: your own practice exactly as your coaches read it, who can see it, and what stays private.
See your teams - ImprovedEveryone
See every coach of your team
Your teams now lists every coach of each team you are on, with the date they started, and points out any coach added since you joined: a new coach sees your practice too, and you can leave whenever you like. Coaches can now be invited to co-coach a team, and accept on Your teams.
See your teams - ImprovedCoaches & moderators
"Still don't get it" never points to a player
The counts on your Coach page now come only from marks players made while on the team, so switching a name off or changing your roster never changes them. Questions show once your team has three players with linked accounts, and when nearly everyone marked one it says "most of the team" rather than a number that would name them all. And if buzzes recorded at practice cannot be sent, the recording bar now says why instead of waiting.
Open the Coach page - NewEveryone
Mark a question you still don't get
After you see an answer, press Still don't get it on any question that still makes no sense. It waits for you on Review, under its own tab. If you are on a coach's team, your coach sees which questions two or more players marked, and how many, never who, so the team can talk them through at practice; coaches find them on the Coach page.
See your list - ImprovedCoaches & moderators
Invite each player with their own link
On Teams and rosters, each name now has a Make a link button: send that link to the player however you usually reach them, and when they open it and join, their account goes on their own name, even if they had no account yet. The team's join link can be shown as a QR code to scan in the room, and a new student who signs up from either link comes straight back to join.
Invite your players - NewCoaches & moderators
A Coach page for your teams
Coaches have a Coach link in the menu. It shows each team at a glance: which linked players practised in the past week, the subjects to work on from your recorded practices and from their own practice, and the last practice you recorded, with the way to the roster, invites and recording one click away.
Open the Coach page - NewCoaches & moderators
See your players' own practice
Coaches can now link a name on their roster to the student's own account, by inviting their email address or sharing a join link. Once the student accepts, the coach sees how often they practise on the site, how they do in each subject, and every question they got right or wrong. Students choose which teams to join on Your teams, and can leave whenever they like.

343 more questions say where they differ from your packet
If the site's version of a question isn't the one printed in the packet in your hands, moderator mode tells you — and 343 more questions now carry that note, most of them middle school. Where the answer differs you get the packet's key, the site's key, and the reason the review gave. Nothing about the questions changed; what changed is that you are told.
Open moderator mode - NewCoaches & moderators
See which rounds can read themselves
Picking a round in moderator mode now shows whether it has read-aloud audio, and whether someone has listened to that audio all the way through. "Audio heard" means a person checked it; "Audio" means the recordings exist but nobody has listened yet, so read with an ear open. A round shown as part way through ("Audio 106/110") has recordings for most of its questions and you read the rest.
Pick a round - ImprovedStudents
Fairer grading on the newest middle school sets
Typed answers on middle school sets 11 and 13–16 are now graded against reviewed answer rules. Every answer the packet accepts counts, plus common spellings, symbols and units: "Lv" for livermorium, "9.8 m/s2". Part of an answer no longer passes for the whole: "tobacco" isn't tobacco mosaic virus. Everywhere, "negative 2", "30 percent" and answers typed in capitals with "THE" in front now grade as they should.
Practice now - ImprovedEveryone
A new logo: the flask timer
SciBowl.club has a new logo: a round-bottom flask that is also a timer, with three quarters of its time still to go. It's in the menu, the browser tab and on your phone's home screen.

The rules videos play like an embedded player
The rules videos open on a clean title card with a Play button (on a phone, the controls no longer cover the credits), full screen now fills the screen edge to edge, and the length shown matches the player. Keys work as on a video site: Space or K to pause and play, ← and → to skip 5 seconds, F for full screen, M to mute.
Watch the rules videos - NewStudents
Your practice calendar
Stats now has a practice calendar: a year of days, shaded by how many questions you answered, with your days in a row and how many days you practiced this week, in the past 30 days and in the past year. Set a weekly goal (3 days to start) and the Practice page shows how this week is going. Your past practice is already on it.

Middle school subjects match the packets
Middle school Earth Science is now Earth and Space, the name the middle school packets have used since 2010 and the 2026 rules use, so it's shared with high school. Subject pickers now only offer subjects there are questions for. Your saved subjects and stats carry over.

The officials' reference has a clearer name, and corrections
The printable reference for moderators, timekeepers and scorekeepers is now the Officials' Quick Reference, next to the rules videos, so it's no longer confused with Moderator mode. Old links still work. It was checked against the 2026 rules: a toss-up read in full is not re-read for the other team; blurts, talking and answering without buzzing are listed together; and it now covers buzzing too soon, judging answers, distractions, recognizing the wrong player, the audience calling out, and who may challenge.

Science Bowl rules, explained in two short videos
Part 1 shows how a real match works: toss-ups, bonuses, the clock and the score. Part 2 acts out the mistakes that cost teams points (blurts, stalls, wrong interrupts, talking during a toss-up, bonus mistakes) and shows how the moderator rules each one. Jump straight to any mistake from its chapter, turn on captions, or read the transcript. Presented by PRISMS Science Bowl Club.

Space stops the reading; Enter carries on
When a buzzer goes off, Space stops the voice and holds a running clock — and pressing it again can no longer restart the reading over the student. Enter carries on from a moment before it stopped, and gives the held seconds back. If the buzz came while the question was still being read, it's now recorded as an early buzz for you, with ⚡ already marked so you can undo it in one tap.

Signing out only signs out this device
Signing out used to sign you out everywhere: leaving a school computer also signed you out on your phone. Now it only signs out the browser you're using.

Sign-up asks for your level, and pages load a little faster
Creating an account with email now asks you to pick Middle School or High School. Nothing is chosen for you, so no one lands on the wrong leaderboard by accident. Signed-in pages also load your profile once instead of five times.
Create an account - ImprovedEveryone
Getting started asks less, and never mid-practice
If you've already picked Middle School or High School, the Guided setup skips that question, with a Change link if you need it. The level and display-name questions no longer pop up over a practice or moderator session. A stray tap next to the Guided setup no longer closes it, and every pop-up now works with the keyboard: Esc to close, Tab stays inside.
Open practice - NewEveryone
Full screen for practice and moderator mode
A new button at the top right of every practice session and of moderator mode hides the browser's tabs and address bar, so only the questions fill the screen. That's handy on a laptop in front of a room or on a projector. Tap it again, or press Esc, to leave. It isn't available on iPhone, where Focus mode still clears the screen.

Your level (Middle School or High School) now follows your account
Once you pick Middle School or High School, you won't be asked again on another device, and skipping the question no longer switches you to High School. Practice and moderator mode open on your level wherever you sign in. Change it any time on your Profile.

The bonus shows which team it belongs to
Recording A against B, the bonus row now reads Bonus A or Bonus B in that team's colour, so a toss-up put on the wrong team shows up straight away. In one squad, a bonus read as a toss-up can be marked ⚡ Early like any buzz. Undoing a bonus now brings it back for the same team.
Open moderator mode - ImprovedCoaches & moderators
A vs B: each team gets its own side of the strip
Recording A against B, the players now sit in two blocks, one per team, in the order they sit. When a team answers a toss-up wrong, its whole block greys out, so you can see at a glance who can still buzz. On a phone or tablet every player stays on screen. If the room looks back to front, use Arrange, then Mirror.
Open moderator mode - ImprovedCoaches & moderators
Record a buzz right where the player's name is
When you record a practice, tapping a player now opens Correct, Wrong and Stall just above their name, so your hand hardly moves. For a toss-up that came in early, tap ⚡ Early on the same spot afterwards; keyboard users can still press Shift with C, X or S.
Open moderator mode - NewCoaches & moderators
Coach accounts
Recording a practice and having a round read aloud are now for coach accounts. If you already keep a team here, your account is a coach account and nothing changes. Moderator mode still works for everyone.
Open moderator mode - ImprovedCoaches & moderators
Set who plays A and who plays B on the roster
Each player on Teams and rosters now has an A / B / neither control, and every team shows its split. Before this you could only choose sides while creating a team or in the middle of a practice.
Open the Coach page - NewCoaches & moderators
Record a stall
When a player buzzes, is recognised, and then doesn't start answering, tap Stall (or press S). It scores as a wrong answer, the way the rules say — but it shows up as a stall afterwards, so you can tell a player who freezes from one who didn't know it.
Open moderator mode - NewCoaches & moderators
Share a practice with your team
A practice summary can now be handed to the people who were in it. Turn sharing on and you get a link that opens the grid without signing in — read only, and it opens nothing else: not your other practices, not your roster, and nobody can change anything through it. Stop sharing and the link stops working straight away. Your roster also keeps the order you typed it in, since that is the order they are sitting in, and you can correct a name any time — it fixes that player in every practice they appear in.
Open the Coach page - NewCoaches & moderators
See a practice question by question
A practice now opens as a record of what happened: one column per question, grouped by category with the packet's own numbers, and a mark where each player buzzed. Filled is right and open is wrong; a circle waited for the question and a triangle came in early; an empty cell means that player did not buzz. Tap a question number to see the question. The counts are still a tap away — they just need several practices behind them before a percentage means much.
Open the Coach page - ImprovedCoaches & moderators
How the two sides did, and no answering a question twice
A practice played as A against B now reports each side: toss-ups taken and bonuses converted, including the bonuses a team conferred on. And a question this practice has already answered says so instead of offering the roster again — so coming back to a question, or reading the round a second time for another group, no longer quietly records a second buzz on it.
Open the Coach page - ImprovedCoaches & moderators
Recording now knows how your practice is played
A toss-up gets two tries. With one squad, whoever answered steps aside and anyone else may take it, and a toss-up nobody got has its bonus read as another toss-up. Playing A against B, the second try belongs to the other side — a teammate cannot rescue them — and a toss-up nobody got means no bonus, as in a real match. Players who have had their chance are struck through and their number key stops responding, and when the question is over the strip says what happens next.
Open moderator mode - NewCoaches & moderators
Fix a buzz you recorded wrong
A practice summary now lists every buzz in the order the questions were read, with the question number and the first line of it. Tap one to put it on the right player, change how it went, or take it off altogether — the grid is worked out from these, so it follows. During the round you still get one undo; this is for everything you only notice afterwards.
Open the Coach page - NewCoaches & moderators
Record a practice while you moderate it
Moderator mode can now keep track of who buzzed and how it went — two taps a toss-up, or the number keys and C / X if you have a keyboard. Afterwards you get a grid to show the team: who is strong in which subject, which categories nobody is taking, how the team does on bonuses, and who buzzes early and is right against who buzzes early and is wrong. Save your roster once and put the names in the order the students are sitting. It is yours alone — nobody else can see it — and it keeps no score.

Speed Drill reads like someone talking
Words now appear in place at the rhythm of speech instead of the text jumping and re-wrapping with every word. The progress bar is gone too: in a real match nobody tells you how much of the question is left. After you buzz, we show how far in you were.
Try Speed Drill - ImprovedEveryone
Set your own clock in Timed mode
Timed mode now says why it gives 10 and 30 seconds when the rule book says 5 and 20 — you are reading the question yourself — and lets you change both, including a one-tap switch to the official times. Every mode also shows its keyboard shortcuts, with tap and swipe equivalents on phones.
Open Timed mode - ImprovedEveryone
Type straight away, and more right answers count
The cursor now starts in the answer box, so you can type as soon as the question appears. Grading also accepts more of the ways an answer is written: "the" in front of it, a trailing question mark, curly apostrophes, mixed numbers like 12 9/10, and the alternatives a packet's own answer key says to accept.
Practice now - ImprovedEveryone
If we mark a right answer wrong, tell us in one tap
“My answer was correct” now counts the question for you AND sends us what you typed, so the checker gets fixed for everyone. Reporting has a matching option, and short-answer questions say up front that capitalization, spacing and punctuation don't matter.

Math answers written with symbols are graded correctly
On questions whose answer uses a symbol or function — cos x, √2, π/4, ln x — typing the answer was marked wrong. It is now marked right, and spacing no longer matters: x^2+y^2=169 and x^2 + y^2 = 169 both count.
