Divisibility rules,
at arcade speed.
A number falls. The pill asks: divisible by 7? Swipe right if it is, left if it is not. Wrong answers pile up, and when the stack hits the line, the run is over. Built by a maths teacher to make the divisibility rules for 2 to 10 automatic.
One email on launch day, nothing else. No newsletter, no sharing.
Divisible or not? Decide fast.
Numbers fall
The rule pill sets the question, like divisible by 3. Swipe right for yes, left for no. The rule changes as you play, so you can never switch off.
Mistakes stack up
Every wrong answer lands on your stack. Reach the line and the run ends. Charge your lightning with correct answers and clear the whole stack in one strike.
One Daily, same for everyone
The Daily Challenge deals the identical run to every player in the world that day. Class and friend leaderboards compare like with like, always.
Watch yourself climb.
Every player in the world gets the identical Daily Challenge run each day, so the board is a straight race. Beat your morning score at lunchtime and your row glides up the class board, like this example.
Play well, earn the look.
Eighteen tile skins to earn, revealed one at a time as you play. Three ladders run side by side, dailies played, correct answers and daily streaks, and Diamond, Circuit and Eclipse sit at their summits. No spoilers here: every look reveals itself in the game.
And one more: Squad, unlocked when 3 friends join with your code.
Find the gap. Close it.
Every Daily quietly records how you did on each rule. Drill Mode then takes your weakest ones and slows the game right down: no fall clock, calm 25-tile sessions, the rules you choose in focused blocks, and every miss explained with the working for that exact number.
Teachers see the same picture for the whole class, so "8 needs another lesson" stops being a guess.
Drill Mode turns the red bars green.
One Daily. Whole-class bragging rights.
Every day the game deals the identical Daily Challenge to every player in the world, so beating your mates is a straight race. Freeze buys thinking time, lightning wipes your mistakes, and every run charges you towards the next skin.
- You play as a picked name like SwiftFalcon42. You never type any personal details.
- Your class code shows today's class board from any browser. No account, no download.
- Skins, streaks and the worldwide boards arrive on iPhone and Android this September.
Each one explained with worked examples on the rules page.
A class up and running in two minutes.
Create a class, print the code sheet, and pupils join by typing the code into the app. No pupil emails, no pupil accounts, no parental-consent forms, because pupils never enter personal data at all. Classes and the dashboard are free.
Codes, not accounts
One six-letter code per class, on a printable sheet for the classroom wall. Pupils tap JOIN CLASS on the app's home screen and type it in.
Boards and insights
Daily class leaderboards per tier, plus per-rule accuracy for the class, so you can see at a glance that 8 needs another lesson.
Names stay yours
Optionally add a roster (first name and last initial only) to see who is who. Rosters are visible to you alone, under your school's authorisation.
- KS2: Covers the Year 5 and 6 objectives on multiples, factors and divisibility, and makes recall fast enough to use.
- KS3: Builds the fluency with factors, multiples and primes that the KS3 programme of study assumes before HCF, LCM and prime factorisation.
- GCSE and IGCSE: Keeps divisibility instant, so simplifying fractions and factorising cost no working memory.
Screen time you can actually feel good about.
Five minutes of Divisible Dash is five minutes of mental maths at speed. It is made by a serving maths teacher, and it never collects personal data from players. Not as a policy promise, as a design fact: there is nowhere in the game for a child to type their name, email, age or anything else.
- Your child plays as a picked name like BoldBeaver69, chosen from curated word lists. No free text, no chat, no strangers.
- No adverts, no tracking, no third-party analytics, no subscriptions. The Daily Challenge and three practice runs are free every day. If your child wants more, one optional £4.99 unlock, paid once, opens unlimited practice and Drill Mode for good.
- Real names only ever exist where a teacher typed them, visible to that teacher alone, with the school as data controller.

Divisible Dash, quickly explained.
What are the divisibility rules?
Quick digit tests that tell you whether one number divides exactly by another, with no long division. A number is divisible by 3, for example, when its digit sum is. Every rule from 2 to 10 is explained with worked examples on the divisibility rules page.
Is Divisible Dash free?
Yes. Every day you get the Daily Challenge, the same run as the rest of the world, and three practice runs, free. Class dashboards for teachers and class boards on this site are free too. Want more than three runs? One optional £4.99 unlock, paid once, opens unlimited practice and Drill Mode for good, no subscription, ever. The app arrives on the App Store and Google Play in September 2026.
Can my school or class use it?
Yes. The teacher dashboard is free: create a class in two minutes, print the code sheet, and pupils join with the code, no pupil accounts or emails. You get daily class leaderboards and per-rule accuracy insights.
Be there for day one.
Divisible Dash lands on the App Store and Google Play in September 2026. Until then, teachers can open their free class dashboards, and telling one colleague or one class is the whole marketing plan.
