Pick the right answer.
For grown-ups
Answers start with counting to ten and get harder on their own as they are got right, so a four year old and a seven year old can both play. There is no clock and no buzzer. A wrong answer just asks again.
Every ten right answers earns a coloring page to print. Fifty right in a row earns a certificate with a space for a name. Nothing is sent anywhere: the score lives in this browser on this device, and the name on the certificate goes straight onto the printed page and is not stored.
