The game "Balance Stack" is an interesting logic puzzle in which you will build turrets from figures, like a house of cards, so that the building does not fall apart. Click the arrow in the center to start playing. Click on the screen to show the shapes. At the top are different blocks. Below is a platform on which to build a structure. Click on the place on the platform where you want to place the block. In the first level, you need to put only one die. Then you will need to build 3, and put a triangle on top. The clock will appear at the top. If the structure survives until the clock hand circles, you will advance to the next level. To do this, click "Next", to restart – a twisted arrow.
