(plastic, base + top + 5 pairs of 1" diameter balls

There are 5 pairs of colored balls, using the colors white, yellow, pink, and blue (all of the 6 possible combinations except pink-blue):



These pairs must be placed to form a pyramid so that no two balls of the same color are touching. The directions say that you should also not allow the same colors to touch as you are building, even for places that are not visible when the puzzle is completed. This is a relatively easy puzzle that is fun for children; it has fewer pieces that the Smarts Puzzle 4 high pyramid made by the same company. It has more than one solution. The puzzle pictured here is the golf version; the same puzzle has also been advertised / sold with other sports themes (soccer, baseball, basketball, tennis, football).
