Loved it!!! However what do you guys consider moves I counted every time a ring came off or went back on for 1-7 ring puzzles these were the calculations I found Catacombs puzzle 1 ring 1 move 2 rings 2 moves 3 rings 5 moves 4 rings 10 moves 5 rings 21 moves 6 rings 42 moves 7 rings 85 moves 8 rings 170 moves 9 rings 341 moves 10 rings 682 moves 11 rings 1365 moves 12 rings 2730 moves 13 rings 5461 moves 14 rings 10922 moves 15 rings 21845 moves 11-15 were just for fun but if you guys would be willing to make a 15 ring puzzle I would gladly be the first to try it!;)

I would like to make corrections to my revue. The mathematics is in error. It should be 2^n instead of n! so the numbers of move required to solve the puzzle is much smaller. as follows. 5 rings: 2^5 = 32 moves. 6 rings 2^6 = 64 moves. 7 rings 2^7 = 128 moves. 9 rings 2^9 = 512 moves. 10 rings 2^10 = 1024 moves. My mistake I don't know why i thought the math is n!. Sorry for the wrong info. I apologize.

This wire puzzle is a mathematical equivalent to the Tower of Hanoi which requires n!(factorial) nuber of moves to solve the puzzle. I can complete the 7 rings Catacombs in in around 5 minutes, which takes 7! that is 5040 moves without getting lost or confuse. The 9 rings Catacombs would require 9! or 362,880 moves, that take be theoretically 72 times as long without making a single mistake. Now a 10 rings Catacombs plus require 10! moves. You do the math.
