Nice package containing 4 cubes with 4 different colors on the 6 sides. The object is to arrange them in the holder such that there are 4 different colors along the length. Its a puzzle patented in Detroit in 1900. A statistical analysis of this puzzle shows that if you force 1 side of the puzzle to be correct, you have 1 chance in 14000 of the other 3 sides being correct! A great statistical analysis of this puzzle is now available with purchase. You math folks will love this work done by Puzzle Master Mike Czerwinski of Menomonee Falls, WI.

Fun and challenging! I was worried about getting this size instead of the jumbo but it's plenty big enough for me (adult). the blocks are about 1 inch square and the colored dots are generous and very easy to see - just a little under 3/4 inch diameter. nice wood holder - the top is open and the other 3 sides have circles cut out to see the colors. I took the blocks out to work with for more space but if you have fingernails you can get them out pretty easily. already driving me nuts!
