Bastille is a challenging packing problem with only one solution.The basis of this game is that the 7 identical pieces of this puzzle symbolize the last 7 prisoners in the Bastille at the end of the French Revolution. Actually, the "prisoners" could leave the Bastille through one of the six equal square openings. As a liberator you will have to show them the way. There is only one "escape route". Once freed, one can also "show" the "prisoner" the way back to the Bastille.

What appears to be a simple cube is an interlocking maze that continually changes its state with rotations, dead ends, and deception. Simple disassembly is a challenge; reassembly is genuinely an accomplishment.Daedalus is difficult to make. Each puzzle contains pieces from...

12 Piece Separation.  On of Coffin's classic designs of which he is most proud. Made by Thomas and Jeremy Moeller who own Artifactory puzzles and sold for many years at Portland Market. I have no idea if they are still selling but I bought this puzzle back in 2010.I'd describe it as nice large playable, wooden version of the puzzle. It has some cosmetic flaws at the ends of each piece which are noticeable on close examination. It is still a great puzzle for play and display, with each piece bei...
