I made this game for a friend that needed something similar to be used in a project.
Fun for the number lovers, but that is where it ends - not too innovative or exciting.
Please comment not too harshly - it is only a small game.
Hope you enjoy it though.
Some people complained about some puzzles being unsolvable.
Sorry, I did not realize it.
I did change the shuffling algorithm now. Now I am for sure it works.
