Roxanne and George Puzzle
Roxanne and George puzzle is one designed by Alfons Eyckmans after their visit to his home. It is very similar to his Adam and Eve puzzle. It is a 12 piece burr with a very difficult level of 45 (32.3.1.1.1.1.1.1.2). The twist is an additional two pieces (Roxanne and George) are presented with the goal of assembling all 14 pieces back into a burr with a difficulty of 47 (11.16.1.1.4.1.1.3.4.2). The 14 piece version has a unique solution whereas the 12 piece version has 49,687 solutions, the most difficult being number 49687. Even with the aid of BurrTools* you will find solving this puzzle to be very difficult, yet very satisfying once you solve it. The colors of the pieces match the ones in BurrTools to make it a bit easier - always good to have a color matchup between the digital and physical.
