To play Geometry Tower, use your mouse to move the position of the block. When you have it in the right place, click the mouse to drop it. There are 20 levels in the game, with increasing difficulty as you progress. In Endless Mode, you can try to build the tallest tower possible, facing a variety of shapes including crosses and zig-zags. Once a block is placed on the platform, it cannot topple over. However, the new block being dropped is vulnerable to falling off the map. Try to grab all three stars in each level for an extra challenge and use your planning skills to build a stable tower in this puzzle game.
