Tetris Blockout

The game is for those who want to develop their spatial imagination and abstract thinking. This brain-twister is from the category of good old Tetris. The only thing is that you play not in two dimensions, but in three of them. Just imagine that you are looking at a tetrahedral "glass" from above. Different figures, formed out of blocks, begin falling down the "glass" gradually going faster and faster as you earn your points. As you have already guessed, you have to fill the "glass" with figures evenly, without holes and gaps. Once the layer is completely filled, it burns down, giving you points. Figures can be moved through the inside space of the "glass", as well as rotated in three axes.
