The name itself tells you this is a Monotris challenge. So, you should know that there is a difference between monothris and tetris. You will get monotris shapes falling down and you can change their direction and move them left or right with your keyboard arrow keys or WASD. The goal is to create Tetris shapes, so try to make a match of four monotris shapes and earn points. Play and see how far can you get with the Monotris adventure.
