6 years ago I found out this game, and every time I needed to swap my device this was one of those games that always ended up on my pocket
The game has both luck and strategy, as your (and opponent) rolls decides the outcome of the match... You can even defeat bots of like 20 levels ahead if you understand what you are doing, and get lucky
Since the size of this game is astronomically small, I suggest for you to try it out and check the controls by yourself... As the tutorial gives only the basics. And an small advice is to quit the app before lossing the match, that way your credits are basically endless
