Use your mouse to stack the boxes! You have to be really careful in this stacking game- because you can see what you’re going to get next! This game has a realistic physics engine because if you don’t stack the boxes just right…it will all collapse. Each level has a unique twist to it. Now, remember that you aren’t dealing with the same size or even same shape blocks! Squares, triangles, circles are what you will have to deal with. So try and anticipate what move you’re going to make next and remember it could collapse at any second if you’re not careful!
