4 by 4 - a new way to play the matching game 1.0
How To Play:
Rearrange the pieces into 4 by 4 squares of a same color by swapping a piece with one of its 8 immediate adjacent pieces. You can simply drag a piece from its original position to its new position. The less moves and less time you use, the better.
Double Tap: start a game, start a new game.
Drag: move a piece.
