"FITZ" is a challenging, double-sided, jigsaw puzzle with 81 identical center pieces that fit together in more than 860 ways. The colored graphics on both sides of the puzzle are comprised of a multiple mix of 12 distinctly different, color banded, diamonds, each with different sequence of color bands. Each side of the puzzle has a different arrangement of the 12 different diamonds. When combined with the fact that the jigsaw puzzle pieces are cut from two sides, not one side, the FITZ puzzle is one of the toughest jigsaw puzzles to solve. FITZ will give you FITZ!
