9-pin puzzle resembles Caesar solitaire[]
Might be an interesting tid-bit to add to the wiki is that the last pin puzzle which requires all 9 pins to add to 15 in a 3x3 configuration is most likely based of Caesar solitaire.
Infact I used this solution (https://www.solsuite.com/games/caesar.htm) to solve it:
| 2 | 7 | 6 |
| 9 | 5 | 1 |
| 4 | 3 | 8 |
