The aim of this game is to guide the ball safely to the target by replacing the blocks within the level. Green Blocks can be destroyed and placed and are effected by gravity. Gold blocks are stationary. Hold down your left mouse button on a green block to destroy it and add it to your inventory. Click on a block in the inventory to select it, click again to rotate it, then click on top of a block on the map to place it. Great fun awaits when you play Challenger Ball!
