Questions parents ask
Do I need to create an account to play?
No. Tap Play and start. Progress saves on that device. A free account is optional and only adds cross-device sync and unlimited play time.
Is there really no advertising?
Correct. There is no ad network in the game. The project is supported by an optional Family Edition purchase for grown-ups and a tip jar.
Which math skills are covered?
Addition, subtraction, place value, time, times tables, division, fractions, decimals and word problems, tagged from grade 1 up to grade 8.
Is it only math?
No. The same adventure includes spelling and science, so one game covers three subjects and one parent view reports all of them.
