The Giant Puzzle was first introduced in 1888 by McLoughlin Bros of New York. It has a bit of a Sudoku edge to it, and its really hard. From Creative Crafthouse and all high quality hardwood construction. Its quite a beautiful puzzle to look at.  They kept the orignal name: "The Giant Puzzle" but its not giant sized, only about 5" square. It has 25 pieces in the base. Each piece is different. There of 5 pieces of each color. The the numbers 1, 3, 5, 7 and 9 are printed on the handles of each color. The handles are a nice feature of this puzzle which we added from the original design which just had flat blocks.

The object is to arrange all the pieces in the base such that there is no color repeated on any row, column, or any diagonal. Also, no number can be repeated on any row, column or any diagonal. Also, each row, column and major diagonal must add to 25. To tackle easier tasks to warm your brain up, you might try to tackle each of the requirements separately (that is, just work on colors, or just work on numbers, or just work the 25 addition) before you take on the full challenge of making them all happen at once! This terrific puzzle is very challenging and will highly appeal to the person who enjoys Sudoku or enjoys logic puzzles.
