RunAway
Designed by Minoru Abe, this one made by J. A. Storer 2011.
(cardboard sleeve, Purple Heart, Cherry, Maple tray and pieces, 4.6" x 8" x 5/8")
The start position has pieces labeled 1, 2, 3, 4
(in that order)
along the bottom,
and on top a U-shaped piece X that has piece O captured inside.
The goal is to slide the pieces so that 1, 2, 3, 4
(in that order)
is on top.
One way to think of solving is to repeatedly place the puzzle in a position
where there is an empty vertical column that allows pieces to be exchanged.
Here are the start position,
the end position,
and each of the empty column positions in a 45 move solution
(and with 1 or 2 additional moves the X and O pieces can be arranged as desired on the bottom).
