It's hard for me to get the feel of what is this game about by just reading the description. The screenshots look interesting and I'd be happy to try it if it was free or if I had more information about it.
The game is very easy to understand.
(Your Turn)You select a digit from the rack and your opponent try to guess the digit you've selected.
(Opponent Turn)Your opponent selects a digit and you try reading your opponent's mind to guess the digit your opponent played.
It's all about intellectual guessing.
If your opponent make a wrong guess the digit is added to your score and vice versa
