Start with two of our best sellers:
Safecracker 50, Dave Janelle's five-ring math puzzle with one solution among 1,048,576 positions, and
Calibron 12, our reproduction of Theodore Edison's 1933 twelve-block puzzle. For a serious solver, Stewart Coffin's
Martin's Menace, his design number 217, sits in our Impossible Puzzle Series, and his
Cracked Egg and
Five Fit are under $50 as well. We make Coffin's designs with his permission. For someone who likes codes,
Enigma III has double-sided wooden gears with a different scrambled alphabet on each face.
