A fun and addictive game, Crashdown is simple enough to start playing right away but challenging enough to keep you entertained. Colored squares start building from the bottom up, causing your pile to grow higher and higher. You have to click on 3 or more of the same colored squares to remove them. The more adjoining blocks you remove, the higher your score. Advance to the next round when the lines counter hits 0. Hint: look at the bottom of your screen because that will tell you what colored squares are coming up next.
