Full Stacks is a free puzzle game. This is a world of donuts. Donuts are delicious but they are also dangerous and they need to be stacked in a specific pattern in order to be of any real practical use. Full Stack is a game that allows you to stack all of the donuts you want in but you must do it in specific patterns. The patterns in this game are not 2 Dimensional, they do not go up and down and left and right, but they also have a depth to them, a third dimension that makes the game all the more challenging and all the more fulfilling. Ignore the colors and focus on the depth and the shape. Make sure that the stacks you're making do not go over or under the height allowance and that they fit all of the pegs perfectly. In this game, the pegs are your guideposts. The pegs exist so you know where everything is supposed to go, follow the pegs and drop the donuts on the pegs and you'll finish the game a true hero.
