Its the 3-D building game with a colorful twist! As players race to build towers using their 'Chameleon''' blocks, there's a surprise with every move - the Chameleon blocks magically change their colors!Place one red block on a tower and the block below turns green. Choose another red block, add it to the tower, and the block below changes to red. You'll need skill and luck to correctly 'predict' what colors will appear. Matching colors earns you another turn. If block colors don't match, dismantle the tower, block by block, and start from the ground up!The concentration game that builds memory skills! Stack'em up, match'em up, and win!
