Color Switch

In this unusual free logic puzzle game, Color Switch, you'll need speed and attention to match pairs of blocks within just 60 seconds. Your goal is to create pairs of blocks of the same color. Bonus points and rewards are awarded when the geometric shapes on the blocks also match. To select a block, simply click on it. Once one block is selected, click on another block to remove both. However, in Color Switch, just like in Mahjong, you can only select blocks that have at least one open side.
