Questions & answers

Do I need an account or payment?

No. Play free in your browser. Hints are free too.

Is it suitable for children?

Yes. Kids mode uses fewer, larger objects. A parent sets the number of differences and a daily time limit, and the game reminds the child to rest. Parent settings are protected by a multiplication question.

Where is progress saved?

In this browser first. Sign in to sync it to your account and continue on other devices. Without an account, clearing site data or changing devices may lose progress.

Where do the pictures come from?

Every picture is drawn by code from a level seed. Everyone gets the same daily workout on the same day.
