### 1/5 — Very disappointed and too confusing

*2020-04-20*

I got this app for my son and say if the question was 9+1 if I said 10 it would say I said 01! The numbers are also on a bad keyboard and I can’t change the keyboard. For my problems I do not recommend you getting this app and I recommend Squeebles apps instead.

### 3/5 — Nice idea

*2014-01-22*

A nice idea but is complicated unless you make it to write the result from right to left

### 5/5 — hi a love this game but It is not working

*2014-07-22*

All of a sudden, today it zeroed all my points. I had over 720000 and it doesnt let me play anymore, it has null x null as a question. what happened?
