Tetra Flop is yet another packing problem by Volker Latussek. The object is to pack the eight tetromino pieces into a 2x4x4 cage. The hole was designed to allow only the intended solution, while blocking any near-miss solutions. A second smaller hole in the bottom assures the chirality of the solution. Obviously, the solution requires many rotations.
