Color Blocks is an interesting skill game on www.flash-games.net for free. The goal for you is to cover the blocks with the same color as many as possible. In this game, use the arrow keys to move the block which has a frog on it and 1, 2, 3, and 4 keys to change your color. You should make your color same to the adjacent block and pass the frog to it. Every time you get past 100 blocks, you unlock a new color. If you pass the frog to a different color block or a black square, you will lose one life. Come on and good luck!
