The game might be simple but it is very challenging to beat. There are also powerups available to help you along. Select the filled block when it comes; this will make all the blocks of that color disappear from the screen. Keep the white block on screen for as long as possible. Try to beat your own score, as well as compete with your friends on the leaderboards. Who will last the longest?
Drag the white block up and make it stay on the screen for as long as possible.
