World board and leagues
Website: pick a play name and your Arena runs go on the weekly board. App (players 13 and over): turn on Compete worldwide, then move up or down leagues (Bronze up to Grandmaster) each week.
Website: 🌍 World board tile · App: ☰ › Settings, and 🌍 Leaderboard on Home
3Sign-in, data & privacy
- No account is needed to play, on the website or in the app.
- Website: your best scores and level are saved in this browser. Only your play name and score are sent for the World board — no email, no age.
- App: all game progress stays on your phone. Under 13 (or before you choose an age) the app sends nothing about you — no device ID, usage counts, invites or leaderboard. From 13 it sends a scrambled device ID with your points and invite code plus anonymous usage counts, and the leaderboard stays off until you turn on Compete worldwide; then only a random player ID, your nickname, age group and scores are sent.
- The weekly board needs an internet connection and starts fresh every Monday at 00:00 UTC.
4Common questions
What age should I choose?
The player’s real age. It sets the difficulty, from Little Sprout for young children up to Pro. You can change it any time.
How do I type a fraction?
Use a slash, for example 3/4. Decimals like 0.75 work too.
Why did my combo drop to zero?
A wrong answer resets the combo. Get 3 in a row again to bring the multiplier back.
Which mode puts me on the World board?
Only Arena. The other modes are for practice and your own best scores.
Is the app different from the website?
The modes and scoring are the same. The app adds points, XP, daily quests, achievements and weekly leagues.
