I found another game. Drench is an interesting concept, and you pretty much have to play and lose to learn how to play and win. You start with a game board filled with random squares of six different colors, and switch the color of your starting square to match surrounding squares. Each time you do, you add those squares to your 'blob' of control.
You begin the game with 30 color changes, and each level you get one fewer change of color. For such a simple game, it's quite challenging. Hope you enjoy it.
