Free for teaching

The same activity, from classroom to home.

For homework or for fun, children can continue on paper, on a smartphone or tablet, or on a PC with the web app.

The teacher shares a printed sheet, code or QR code so everyone can open the same puzzle.
On paper, children reason with a pencil. On Android or in the web app, they play on a smartphone, tablet or computer.
From within the game, a parent or pupil scans the sheet’s QR or pastes its code. No pupil account to create.

Activities shared by the teacher remain free at home, just as in class.

Android works offline. The browser uses the network to load and to verify a full licence.

Pupils’ privacy comes first.
