How can a 4 piece puzzle be so difficult??. All you have to do is insert them into the frame... It is a Stewart Coffin design (#217) originally called "Four Fit" but renamed by Stewart after Martin Gardner's week long efforts to solve it were in vain. Martin Gardner (1914-2010) is considered the Father of Recreational Math with perhaps the greatest puzzle mind of the 20th century. Martin called it "The finest dissection puzzle of all time". Made under license from Stewart Coffin Note: This is our only puzzle where a solution is not provided, but can be obtained upon request at time of or after purchase.
