The objective of the Keep the Brick online free game is to destroy all the bricks. Choose one brick out of the group of bricks that are coming down and place it onto the same colored group of at least three bricks. This will make them pop and disappear. There are powerups hidden among the regular ones. Be quick to catch them as they will slow down the speed that the bricks are going with or turn the cement mixer aka shooter into a great weapon.
The levels are not short, there are 10 in total. Unlock them one by one as you proceed to the next one. Use the mouse to play.
