At number four is GameHouse’s newest Facebook title, Collapse Blast, which is a variation on its classic arcade title, Collapse. Like certain bubble poppers and wooga’s Diamond Dash, players race to clear a board of colored titles by clicking on groups of three or more same-colored titles. The key difference in Collapse Blast is the addition of power-ups players can buy (or perhaps earn, eventually) for virtual currency. The game launched mid-July.
