XWelltris is a 2.5D Tetris-like game. Imagine that you are looking into a glass from the top. You see four walls and the bottom. Flat 2D figures fall down from the walls one by one. You can move these figures from one wall to another or rotate them. If the figure leaves the wall, then it moves to the bottom while another figure is pushed. You need to form full rows or columns on the bottom. When you form such row it disappears and you receive additional empty space on the bottom and your score increases. Extra points are earned by making more rows disappear at the same time. If you can't place a whole figure on the bottom, then it stays on the wall and you can't place figures on that wall for a while.
