Crazy Stack is a physics-based puzzle game in which you have to stack shapes and avoid them falling. Each level includes a number of stacked pieces and a number of obstacles, which will test your spatial reasoning skills and mental speed. You can use the game's mechanics to your advantage, solving puzzles and making strategic decisions.

How to play:

In Crazy Stack, you have to tap and drag the different shapes, one by one, to stack them. The game will automatically create the right shape and place it in the right position. You can drag the shape to change the position or to remove it. The game's mechanics are the key to your success, so pay attention to them and use them to your advantage.

If one of the pieces falls, the game is over. If the level is too difficult for you, you can skip some of the shapes. The game's controls are easy to use and fun to play, so you won't have any trouble with it.
