ClickSum - What drives someone from sanity to madness? Is it the incessant clicking of the mouse frantically trying to clear the world of its problems? Maybe so. Will playing this game help stop the madness? Probably not, but it's a fun diversion. In this game of reflexes and precision, you must click on the tiles as fast as you can in the required order. The closer you click to a tile's edge, the more points you will earn. The faster you clear the grid the more points you earn.
