Extension for rotatable puzzle piece

1. A puzzle having an extension for a rotatable puzzle piece, comprising:

a housing including a backing frame and a front member connected one to the other;

the backing frame being formed with a fixedly disposed first recess defined by walls formed on the backing frame into which first recess a plurality of guide members are individually attached as an immobile guide member array, and a fixedly disposed second recess, an external boundary of which is defined by the front member, and an internal portion of which is defined by the guide member array;

a plurality of puzzle pieces disposed in the second recess, each of the pieces being individually slidably movable in the second recess, but not rotatably movable when substantially all the pieces are disposed therein, whereby the pieces are movable so as to be arranged in a desired solution in the second recess; and

a channel that operatively communicates with the second recess such that the pieces can be moved outside of the external boundary of the second recess into the channel and rotated therein, thereby rotationally reorienting the pieces;

wherein the rotationally reoriented pieces can be moved into the second recess in an attempt to solve the puzzle.

2. The puzzle of claim 1 wherein the channel is defined by the front member, and the second recess is a latticework recess.

3. The puzzle of claim 2 wherein the channel is also defined by the backing frame, and the external boundary of the latticework recess and the array of pieces each have a respective shape;

wherein the shape of the external boundary of the latticework recess is approximately the same as the shape of the array of pieces.

4. The puzzle of claim 1 wherein the channel is operatively attachable to or detachable from the puzzle.

5. The puzzle of claim 1 wherein the puzzle can be handheld; the guide members are equilateral in shape; and the puzzle is subsequently solved by correctly re-positioning the reoriented pieces by transversely sliding them across the guide member array.

6. The puzzle of claim 1 further comprising an end member that is detachably connected to close an open end of the channel.

7. The puzzle of claim 5 further comprising a locking piece that prevents puzzle pieces from moving when it is used.

8. The puzzle of claim 6 wherein the puzzle pieces have faces that collectively form an image, the recreation of which solves the puzzle.

9. A slidable puzzle, comprising:

a puzzle configured as a planar array of immediately adjacent pieces that slide transversely, both horizontally and vertically, across a latticework recess, which scrambles or correctly re-positions the pieces;

a puzzle housing that supports the array;

wherein the housing includes a backing frame and a front member connected one to the other;

the backing frame is formed with a fixedly disposed first recess defined by walls formed on the backing frame into which recess a plurality of square guide members are individually attached as an immobile guide member array;

the latticework recess is formed by the guide member array, an external boundary of such recess being defined by the front member, and what remains of the latticework recess being defined by the guide member array;

the external boundary of the latticework recess and the planar array of pieces each have a respective perimeter shape, and the shape of the external boundary of the latticework recess is approximately the same as the shape of the array of pieces;

the planar array of puzzle pieces disposed in the latticework recess, each of the pieces being individually, slidably movable in therein, but not rotatably movable when substantially all the pieces are disposed therein, whereby the pieces are movable so as to be arranged in a desired solution in the latticework recess; and

an extension that operatively receives at least one rotating puzzle piece outside of the array;

wherein the piece rotates in the extension, but cannot rotate within the array when immediately side-by-side another piece in the array; and wherein the puzzle can be solved only by first reorienting a piece in the extension and then transversely repositioning it, in at least two transverse directions, inside the array;

the extension for the at least one rotatable puzzle piece is outside the shape of the puzzle, the at least one puzzle piece having the ability to rotate on its axes when moved into the extension;

the puzzle has a single, horizontal, vertical, or diagonal extension; and

the extension comprises a channel that operatively communicates with the latticework recess such that the pieces can be moved outside of the external boundary of the latticework recess into the channel and rotated therein, thereby rotationally reorienting the pieces;

wherein the rotationally reoriented pieces can be moved into the latticework recess in an attempt to solve the puzzle.
