Building towers in virtual space is very popular, because in the process of building a tower you train your reflexes. The same thing awaits you in the Stack game. As a building material, multi-colored square or rectangular tiles are most often used. They move in a horizontal plane and as soon as they are above the tower, you must quickly press the plate so that it is installed on the stack. If a tile is misaligned and moved, the protruding edges will be sheared off and the next tile will be smaller in the Stack.
