Nothing like the ad, you start with a group of 3 randomly generated pieces that you have to use to fill one of the 9, 3×3 squares in the playing area. Upon filling one of these squares the square refreshes & you earn points. The game is rigged, the pieces you are allotted after awhile are incompatible with the arena & if none of your remaining pieces fit then you lose and get a popup ad(hitting skip automatically opens up the playstore, very infuriating). This is an app designed to make revenue.
