This game is fun even if I can't quite figure it out! It is a lot like tetris only you are looking down on the board. Use the arrow keys to navigate, space bar to place, "a" to discard and "z" and "x" to rotate. The board starts to disappear as you are putting your pieces in place. Sometimes the board will rebuild, but I am not sure why! If you figure it out let me know! Have fun!
