Stefka-Flop is part of a series of packing puzzles that were designed by Dr. Volker Latussek. The FLOP series puzzles each consist of a cuboid box completely filled with various tricubes and tetracubes. Each FLOP has a unique kind of rotation, so each solution is different.
Stefka-Flop has only seven pieces; one tricubes and only six of the quadcubes. It is very suited to being a coffee table puzzle. The challenging part is getting the pieces through the restricted opening. Remember, rotations are required to solve it!
