Four Squares - Connect 4 app for iPhone and iPad

A relaxing puzzle game that perfectly combines match three gameplay with Tetris.
The goal of the game is to connect four squares of the same color in order to make formations and win points.
Three exciting game modes will keep you engaged::
FREE mode allows you to create any formation. You get one point for each formation and five points for collecting an item.
TIMED mode challenges you to make as many formations as possible, while racing against the clock.
TRIO mode has a twist: If you make a formation other than the three required ones, a black square is created, which can not be connected with any other square.
