George Washington Puzzle


Manufactured circa 1930.
(cardboard box and 15 wood pieces, 4 by 4.75 by 1/2 inches)

Move the 2x2 to each corner of the puzzle in a clockwise direction starting with the top right. Described on pages 9-12 of the 1942 Filipiak book (which gives a 465 move solution) and on page 99 of Hordern's book (which presents a 122 moves solution). Can be done in 101 moves.

Hordern's 122 Rectilinear (144 Straight-Line) Moves Solution
Here the start position and each position after the 2x2 piece moves:


A 101 Rectilinear (117 Straight-Line) Moves Solution
Here the start position, each position after the 2x2 piece moves, and also position 9 (to fill in the relatively large gap between position 0 and position 19). This solution has the 2x2 piece moving through but not terminating a move at the first three corners; to count visiting a corner as a separate move, a position can be added before each of positions 37, 59, and 81, for a solution of 104 rectilinear (117 straight-line) moves.
