If the DuBlox lays flat on them you will have to start the level over. Green Square Buttons create extra green tiles that you can use to get the DuBlox to the end of the level. Press the Green Square Button again and the tiles will disappear. For Orange Diamond Buttons to work they must be pressed down at the same time with the DuBlox standing-up. These Buttons create orange tiles that can be used to get the DuBlox to the end of the level. The Yellow Circle button is a mystery. Press it and see what happens. . Best Dublox games.
