A variable three-dimensional labyrinth comprises a base, a plurality of central blocks, side blocks, corner blocks, wherein a plurality of buckling pillars are mounted on the base for buckling the central blocks. A plurality of hollow tunnels are formed on the central blocks, the side blocks, and the corner blocks. A holding part is mounted on each central block. A pivotally connecting part is integrated with each side block and each corner block. The pivotally connecting part is pivotally mounted between the base and the central blocks. A ball is moved into the hollow tunnels of the blocks from an entrance hole and moved along the hollow tunnels by rotating the blocks until reaching an exit hole, wherein the exit hole is formed on an exterior surface of one of the blocks, and the entrance hole is formed on an exterior surface of another block.
