Insane Math Game

Open Insane Math Game and you are playing — a Hypercasual game that runs on the page rather than beside it. Taps and swipes are the whole vocabulary — a phone plays it best. Listed under casual, educational, game, interactive, kids.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Nothing is saved to an account, because there is no account — progress lives in this browser.
