### 3/5 — Dogs hate it

I like the game but the sounds it makes are at a frequency that all dogs find very distressing. Wish they would fix that issue so I don’t have to torture my baby or play with out sound.

*2019-06-05*

-edit 2- I really liked this game but now it seems to have lost its English translations and is entirely in another language... can’t figure out how or if I can switch it back to English.

-edit- all bugs seemed fixed now! Thanks, I haven’t encountered any recently. Updated to 5 stars

I absolutely love this game, my new favorite mobile game for when I need to kill some time.  I like math games in general.

I’ve been looking for a fun simple math game that isn’t catered around grade school kids in theme. This one is great! Suitable for both kids and adults who love math.

**Developer response:** Thank you so much for your comment!
