Aritmetris
Aritmetris
Math that goes down easy.
Aritmetris is a fast and playful mental-math arcade puzzler where the right calculations clear the board.
Enjoy a quick brain warm-up, climb all the way from primary school to university, chase new records or turn arithmetic into a local duel.

Think fast. Make it add up.
Each falling piece brings two numbers and an operator. Watch the current target, connect pieces horizontally, vertically or diagonally, and build the right calculation before the board fills up.
Create combos, chain calculations and keep your cool as the numbers get bigger and the game gets faster.
Four ways to play
- Classic: Start with simple additions and work your way through 12 increasingly challenging levels.
- Sprint: Skip the easy lessons and face bigger numbers and trickier operations much sooner.
- 1 vs 1: Challenge a friend or your partner in a local competitive match.
- 1 vs CPU: Take on the computer and choose how difficult you want the exam to be.
1 vs 1 and 1 vs CPU are available on tablets and PCs.

Built for quick sessions and easy comebacks
- Play instantly in your browser.
- Install it for quicker access and offline play.
- Use keyboard, mouse, touch controls or a gamepad.
- Unlock achievements and try to beat your records and statistics.
- Progress through 12 levels, from primary school to university, with the speed continuing to rise beyond that.
- Available in English, Spanish, Catalan, Galician and Basque.
- No accounts, daily chores or notifications. Just open the game and play.
Same game, brand-new personality
Aritmetris v2 keeps the gameplay intact while giving the entire experience a new school-inspired visual identity, from the menus to the game boards.
There is also a new double Easter egg hidden somewhere. No spoilers.
