Further notes: This maze and the “Not-So-Easy Number Maze” both use the same set of rules. These rules are not an original invention of mine; in fact, mazes with these rules are now something of a tradition. The layouts of these two mazes, however, are original.
As far as I can tell, the earliest use of these rules was in Sam Loyd’s puzzle “Back from the Klondike,” first published in Loyd’s newspaper column in 1898. I would guess that Loyd invented these rules, though you can never be sure about these things. You can find Loyd’s puzzle in Mathematical Puzzles of Sam Loyd, edited by Martin Gardner. I highly recommend that book, as well as Gardner’s follow up, More Mathematical Puzzles of Sam Loyd. I do not, however, recommend “Back from the Klondike.” It’s much too complicated. It uses a huge grid of 325 numbers. Loyd used the puzzle as a contest in the newspaper, and he made it overly complex so he wouldn’t get too many correct entries.
If you’d rather not spend hours on-line trying to solve these number mazes, you might try playing them off-line. To do this, first visit the maze on-line, and maybe make a few moves to make sure everything got loaded. Then later, restart your browser in off-line mode and go to the maze. If the maze is still in your cache, it should load in. Or maybe it won’t—you can never tell what these browsers will do.
