About game
In the game, you move and rotate two tetrablocks simultaneously, which simultaneously change different game boards.
This game develops spatial orientation.
How to play
You control the tetrablocks that appear at the top.
In the desktop version, to rotate the tetrablocks, press the up arrow key; to move them left or right, press the corresponding left or right arrow keys; to move the tetrablocks down, press the down key or the space bar.
In the mobile version, to rotate the tetrablocks, press the rotate button (bottom right); to move them left or right, press the corresponding left or right arrow keys; to move the tetrablocks down, press the button with the down arrow.
When on one playing field all the cells of one line are not empty, then on this playing field this line is removed and all the upper lines are lowered down.
The game ends when no more tetrablocks can be moved.
