The arcade
Everything runs in the browser and saves your progress on your own device. Best on a tablet or a laptop; most of them work on a phone too.
Hop between islands solving number puzzles, collect stars, coins and eggs, and hatch a companion.
Word problems inside real stories. Difficulty moves on three axes at once: reading load, number of steps, and skill.
Four themed islands covering science, geography and cultures, history, and language arts.
Olympiad-level maths, English and science. Earn currency, open booster packs, and fill a 150-card collection.
A trading-card battler where your attacks are powered by solving maths puzzles. Build a deck, run the campaign, beat the bosses.
Two modes in one. A read-along storybook with mini-games for the older reader, and eight gentle tap-anywhere rooms for the youngest.
The first time a game opens it asks who is playing. Type a name once and that name carries the save: stars, coins, cards and chapter progress all follow the player onto any other tablet or laptop. Coming back later means tapping the same name from the list.
Two children on the same tablet each keep their own separate progress - use the switch link in the corner to change player. There is still no password and no email; the name is the whole account. If the site cannot be reached the game keeps playing and saves locally instead.
