Super Stacker 3 is a building-block game based on the popular Super Stacker series. It features anthropomorphic shapes (purple boxes, yellow circles and green triangles) that a player must use, along with knowledge about building blocks, geometry and physics, to complete design challenges across 40 levels. They might build a tower, make legs for a giant or create a structure with a flat top.
The player receives a certain number of different shapes in each level that they review on a bar above the playfield. To succeed, they merely need to create a stacked structure with the shapes that somewhat fulfills the challenge and doesn't topple for at least 10 seconds. If the player fails, the shapes display negative emotions, such as anger, concern, fear and shock.
Super Stacker 3 is almost identical to Super Stacker 2 except that it offers more than 40 news challenges and design possibilities. It also doesn't have a stack editor for designing new stacks. That said, gameplay is exactly the same. The player stacks shapes in 10 levels per mode across four modes ranked from easiest to hardest. In this version, modes are known as "packs" (Pack 1, Pack 2, Pack 3 and Pack 4). If the player completes all of them, they can play a Bonus Mode as well.
