Martin's Menace Large is a handcrafted 4-piece wooden brain teaser, Stewart Coffin Design #217, originally called "Four Fit." It was renamed Martin's Menace after Martin Gardner, the Father of Recreational Math, spent a week trying to solve it and called it "the finest dissection puzzle of all time."

Martin's Menace is part of The Impossible Puzzle Series, rated 11 out of 10 Difficulty. That is the top of our five-step scale [Easy, Intermediate, Hard, Expert, Impossible], not a review score and not a joke. Four pieces, and not one rests in a corner, so the usual corners-first start gets you nowhere.

Fit four pieces into the frame. Few solve it without help. The pieces are precision laser-cut from durable hardwoods. Handcrafted by Creative Crafthouse with Stewart Coffin's permission.

• Dimensions: 7 x 7 x 0.75 inches in the frame.
• 4 pieces. Ships unsolved.
• Solution available on request [not included in package].
• Engrave up to 45 characters on the base.
