This unique pyramid puzzle may or maynot have a solution! LOL! The idea is to make a solid pyramid with as few pieces left over as possible. Most people seem to have 4 pieces left over. I have had as few as 2 pieces left over but have not been able to repeat that victory! This piece varies with each creation. Buy what is in stock or order something custom made! This item can be customized to any color combination, just email me at nsr885@yahoo.com.
