In stackle you get to play with blocks. The blocks are at first placed in a balanced form. You must move the blocks around, making the tower as high as possible. The higher you go the more difficult it gets to balance your tower. You will have to consider the weight of the blocks and the support that they have to build firmly. So get ready to challenge yourself to create the tallest tower made up of blocks.
Try to stack as many blocks as possible to make a tall tower. The number of tiles are limited. As you arrange the tower with the available blocks, make sure that the whole thing does not fall down.
