THE STORY: 

The puzzle was "invented" by Noyes Palmer Chapman, in New York, and it is said that it was, already in 1874, a precursor puzzle consisting of 16 numbered blocks that were put together in rows of four. 

The "Mad Square" was improved in New York, Frank, son of Noyes, and from there, through various connections, Hartford (Connecticut), students in an American school have begun the production of the puzzle and, by December 1879 began to sell both locally and in Boston, Massachusetts. 

Matthias Rice, who ran a timber trade in Boston, began producing the wooden puzzles, in December 1879 and has persuaded a dealer to sell them under the name of "Gem Puzzle". 

In late January 1880, Dr. Charles Pevey, a dentist in Massachusetts has garnered some attention by offering a cash reward for anyone who would solve the Crazy Square.
