### 5/5 — Pretty great

*2020-02-24, version 2.1.0*

There’s lots of adds but other than that it’s great it’s great for your mind and we do it in 7th grade!

### 5/5 — amazing

*2018-10-22, version 1.1*

Lots of levels. Very interesting. Like it！！

### 1/5 — Hard to use, many ads

*2018-10-22, version 1.1*

Controls are difficult and has lots of ads. I wish I could turn off the feature that tells me when I’ve put in a wrong number. Part of the challenge is figuring that out myself.

**Developer response:** Thanks for your feedback. Sorry for the delay. We improve the feature about wrong number, maybe you would like to try it out.
