The 12 different pieces of this puzzle fit into the tray to make a plentitude of different patterns with the 5 left-over holes. Each pattern of holes has many different solutions meaning that this puzzle has literally millions of solutions altogether! It is easier to find a solution with any random pattern of holes, but much more difficult to find a specific symmetric pattern. Ten sample patterns are engraved on the back to show the kinds of symmetries that can be made, ranked “easier” to “harder.” The different degrees of difficulty and endless new challenges make this puzzle one of the most fun on the entire site! Highly recommended.
