The objective of the game is to pass the falling cube though a base zone of the same color.
The base zones change over time. If you try to pass a cube through a different color zone, the cube will stick and block it.
If all zones are blocked, or a tower of cubes stacks to total 10, your game is over.
Game level adjusts with score.
Cube fall speed increases with level.
Score increases when a colored cube is successfully passed through a zone.
