In this video, we learn how to win the Grow Cube flash game. First, make a square shape on the lower right hand side of the square. After this, start to make a line going from this, up to the top and going down to the side. Next, you will start digging on the lower left hand side, then use a tube to help you get to a new level. Keep digging in this same spot, then you will see a door appear. Use the first on the top to get a level up, then continue digging down in the same spot and you will win the game!
