One level at a time
The Play button always offers the right challenge, from age 6 to 11, without ever showing a school grade. Every missed fact comes back later, at the right time, until it is known by heart.
Mental math game · ages 6 to 11
Mental math becomes an adventure
Additions, subtractions and times tables: every right answer draws a magic circle and casts a spell, in a duel with the guardians of the Number Archipelago.

The game
Learning the times tables without noticing
Every right answer casts a spell
Facing a guardian is a race: its magic circle builds up while its spell gets ready. Answer right before it does and your spell hits its circle, all the harder as the answer is quick. The first circle to fade out loses.
Your answer draws a magic circle
Every digit typed adds its shape: 3 a triangle, 4 a square, 5 a star… Numbers get a picture, and they are easier to remember.
An adventure across the Archipelago
One island per chapter, a trial at the end of each, and Professor Pythagoras waiting at the Summit.
25 holographic cards
Every win brings fragments of the guardian’s card. The S, SS or SSS rank, based on speed and accuracy, gives more fragments and a silver, gold or rainbow frame. No luck involved: you earn what you deserve.

Daddy, at first this one (pointing at a level) was hard, but now it’s way too easy!
I am the dad of a girl in primary school. Mental maths and times tables are often the part of maths children like least. I wanted to turn them into a real modern game, with magic, guardians and collectible cards, the game I would have loved as a child. Math Powa was made for her, and it is free so that every child can enjoy it.

No data collected
No cookies, no trackers, no visit statistics. Progress stays on the device, and links leaving the game ask for an adult first.
No ads, no purchases
The whole game is free. No advertising, no in-app purchases, no paid bonuses.
No account
No sign-up, no email address. Several children can play on the same tablet, each with their own profile.
A well-deserved break
After 30 minutes of play, the game suggests a break. You choose the length (20, 30, 45 minutes or never) and can make it strict.
What is still hard, at a glance
The parents area shows the hardest facts, the tables known by heart and those to review.
Designed against frustration
After two mistakes in a row, an easier question comes. A guardian that is too strong slows down a little after each defeat, and hints show the strategy first, then choices, and the answer only at the very end.
