Abacus: Mental Calculation

A nice game. The energy cost is quite expensive though, and runs out easily

Easy to math.

This is very good game

Great introduction course. (but who is kenny lol) Would like a toggle for turning off helper animation or arrow indicators. After initially, they are rather distracting. And what about an easy operator (add minus signs) for free mode; it doesnt need to calculate a result, just a separator for values, to quick show experimentations? Perhaps this display can become optional once one is more fluent..?

Nice app but the touch controls for the screen are a little hard to use, also has a great theme.

Best abacus app on store
