Análisis de la app 4 in a row! para 1 de marzo

Connect four discs of the same color next to each other vertically, horizontally, or diagonally before your opponent. You can play with a friend on your device or online or against the cpu with three difficulty levels. The rules are similar to the tic-tac-toe, but with gravity: you have to drop 4 pieces instead of put them on the board. The game also includes several different graphics.
