Your goal is simple:
-Remove the red shapes without the green ones falling off the screen.
This starts out easy but after level 10 you can forget what you know about gravity...
-If you get stuck there's a link to a walkthrough in the game.
-You can turn the SFX off in the right click menu.
-There's a level editor, give it a go!
Click on the shapes to make them dissapear.
