PATTERN Puzzles (PAT) require the placing or arrangement
of separate pieces of a similar nature to complete surface patterns according
to defined rules. The pattern required may be the matching of edges of squares,
faces of cubes, etc. The pattern may be colour, texture, shape, etc. Where the
pattern is due to differences in shape they must be sufficiently minor not to
obscure the similarity of the pieces.
