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”.
The ¼” thick pieces are precision laser cut from 4 different
hardwoods. The base and cover measure
about 6” square.
