The goal of this game is to get all tiles your color. Your color is green. The opponent's color is purple.
You can change your opponents tiles to your color if you move your tile next to your opponent's tiles. There are two ways to move your tiles:
1) Moving a tile one space will clone that tile (then you will have two tiles).
2) Moving your tile two spaces will pick up your tile and place it down two spaces over, but won't clone your tile.
To move a tile, select the tile you want to move, then select where you want to move it.
