Ratings and Reviews



You should add a mode where it randomizes the settings (who goes first, how many piles, how many stones in a pile, maximum stones removed)



My old math teacher taught me this game and since that I have not stop playing it. The only issue I have with it is it's way too easy. I would have put 5 stars but I need to get better to beat my old teacher (who has never been beaten) and it does not really help me even on the hardest difficulty. They should put multiplayer and I would gladly pay 2 dollars for this

Thanks for the suggestion. In recent updates we have made options to make the AI more difficult, which you can adjust via the Settings page. You can also specify if you'd like the computer to go first. Also the 2 Player option would allow you to play people in person. We'll let you know if we develop a multiplayer version :)

This is a fun game to play and with some practice you can win. This only got two stars because the computer does not follow the same rules you're limited to. When I set the number of blocks removable per move to 3 it would be able to remove 4 and the same happened with other settings. Get this bug fixed and it will be a great game

Developer Response

Thanks for the valuable feedback. In a recent update (version 1.1) we fixed the issue where the computer would not respect the limits in settings. Furthermore there was a bug where settings were not saved between app launches, which we have fixed in the most recent update (version 1.2).
