Cubetti is a puzzle game. It consists of a matrix of cubes with a different image on each face. First you "scramble" the cubes, and then you have to align them again. To play you need special credits named "Cubetti Coins" that you can acquire with the in-app purchase option. When you download the app you get also a certain amount of Cubetti Coins for free in order to test it. Alternatively you can consider to buy the variant "Cubetti Top" which is the one-time purchase version (all inclusive, no coins necessary).
