The most popular computer game around the world is Tetris. Today we want to present on our website a new online game Gridfall, which is a modern version of Tetris. Before you on the screen will be seen the playing field at the upper part of which in turn will appear blocks of various shapes. They will fall down. Using the mouse, you will move these blocks to the right or left, as well as rotate in the space around the axis. Your task is to expose an integral series from the blocks. Having completed this, you will see how this row will disappear from the game field and for this in the game Gridfall will be charged points. Your task is to score as many points as possible for the time allotted to pass the level.
