Gridshock is a twist on matching games. The objective is to keep the grid from filling up. You must do this by clicking on colors that have three or more connected to them. If you are able to clear colors with even more than three colors connected, then you will earn a lot of points. With each level, the timer fills up more quickly, which increases the challenge. The reflexes necessary to make it to the top of the scoreboard are that of a cat, so if you aren't a cat, you might find this to be super-challenging. But, don't worry; this game might be able to bring out the cat-like reflexes that you have.
