This game is great for people who have phones with a physical qwerty keyboard. It plays just like your favorite tetris game. However, for people with phones that are purely touchscreen, then there may be some issues. Some of the issues I have with this game is that whenever I touch the left or right button, it sometimes moves it over 2 "steps" or more. I have to be real careful and try to tap the buttons quickly so it only goes 1 step at a time. Overall this game is great for people who have a physical keyboard and troublesome for people with a purely touchscreen. Since I have a purely touchscreen phone (Evo 4G), I give it a 2 out of 5.
