Gutris

Play this block matching game that takes you inside the human digestive system! Set against a backdrop of organs and body material, you have to stack lumps of blocks to clear the level. The lumps are much like the ones in Tetris. Some are straight lines, some are squares, and some are more jagged. Use the left and right arrow keys on your keyboard to move a piece left and right for better placement. Push the down arrow key to rotate the piece to make it fit better. Push the space bar to drop the piece all the way down to the bottom.
