Holey Moley Bowling Pins Puzzle - arrange all pins such that they are the same height

Your goal is to arrange the pins such that they are all the same height when inserted into the base. The challenge lies in that all the pieces are different lengths, each hole is a different depth, and you have the angle of the base to mess with your mind even further... A fun and artistic puzzle that is joy to play. Its not intimidating so everyone will try it, but you soon find out the solution may not be as easy as you first thought! This model with 10 pieces is a bit more difficult that the 8 pc model with unicycles (available on different listing). An excellent desk or coffee table type puzzle, but it is something that even youngsters will enjoy and have a chance of solving so we recommend for ages 9 and up. A good adult solution time would be 20 minutes. A methodical approach is helpful.... The base is made of precision cut floorboard material. It is super strong, scratch resistant and even washable. The playing pieces are cut from hardwoods and may be maple, ash, or birch. It measures about 9" x 2" x 4.5". It will come packaged unsolved, but a written solution is included.
