ABSTRACT:
A puzzle in which alphabet letters or other graphics are displayed in movable squares forming a grid on a front side of the puzzle. On the back side of the puzzle is another grid of movable squares containing alphabet letters or other graphics. Each square is a part of each of two mutually transverse, continuous bands. One band comprises aligned front side and back side rows while the other transverse band comprises aligned front side and back side columns. The relationship of each square in the puzzle may be changed with respect to every other square. As squares are moved out of the front side grid, they wrap around, out of sight, and change the grid of squares on the back side while bringing an out of sight square into the front side grid. In one electronic version of the puzzle, movement of a square is effected by touching the front side square to be moved and then touching the position on the front side row or column to which the square is to be moved. Grids in a mechanical version have moveable pieces carried in transverse intersecting slots formed by parts mounted on posts and spaced from a core.
