The Fifteen puzzle was first marketed in Boston by Matthias J.
I found a copy but I am missing the "14" piece.
A very slick design - the problem initial position card is visible when you look straight down through the "water."A set of passengers need to be rescued by a set of lifeboats, which can move forward, backwards, or sideways unless blocked.
Since this position has odd parity, it cannot be solved.
To solve this puzzle, I've employed a strategy common in mathematics andoperations research - when faced with a problem, try to find an isomorphismwith another type of problem for which a solution can be more easily found.
The instructions say 24 moves; Hordern says 20 moves.
The patent was denied, perhaps because the 15 Puzzle was too similar to -Kinsey 1878,which specified the tongue-and-groovearrangement now commonly used for holding the tiles in the tray.
Image is of a Russian version called Logi Toli.
Most often their "solution" entailed some way of re-defining the goal state - for instanceplacing the empty space elsewhere than at the lower right,ordering the numbers in some way other than left to right in rows down the tray, or making use of a rotation of the tray itself(thusly leaving the figures not right-side up, or employing round tiles so as to be able to re-right them afterwards).
This is the "three-letter" version of B35.
Sam Loyd really shouldn't even be credited with popularizing the impossible challenge called "14-15"in which the starting position hasonly the 14 and 15 tiles swapped.
