“The Minimal Frame puzzle is made of a square board with a cube in 2 of the corners and 9 puzzle pieces that must be assembled on this board. Goal of this puzzle is to assemble all the pieces on the board in a way that no piece can fall off sidewards. There are 39 ways to assemble the square but only 1 solution where no piece can slide off. Pelikan made this puzzle in a variation of beautiful woods.”
