Abstract
Abstract A slide puzzle comprises a frame forming a rectangular playing surface on which a plurality of rectangular pieces are slidably arranged. The pieces collectively occupy less than the entire area of the playing surface, so that a free space exists to enable the pieces to be shifted. In that way, an indicia (e.g., a picture) carried by the pieces can be completed. In order to positively prevent the pieces from moving, a releasable closing member is provided, e.g., in the form of a filler piece that can be inserted into the free space, or a locking pin insertable through the frame and at least some of the pieces.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
165 words
A slide puzzle comprising a frame forming a rectangular playing surface, and a number of rectangular sliding pieces arranged to travel over the playing surface and containing respective sections of an indicia, the sliding pieces collectively occupying less than the entire area of the playing surface so that there remains a rectangular free space of the same size as an individual sliding piece for permitting the sliding pieces to be shifted relative to one another in order to properly form the indicia, and a releasable closing mechanism for positively preventing relative movement between the sliding pieces, the closing mechanism comprising a filler member insertable into the free space, the filler member containing a portion of the indicia for completing the indicia, the filler member being larger than the free space so that a first section of the filler member carries the portion of the indicia, and a second section of the filler member is of the same color as the adjacent part of the frame.
Claim 2
Dependent Claim
