That's a game for me :-) I love numbers and the mechanics of your puzzle come quite natural to me. I wonder if the concept could be boiled down to a smaller scale without loosing the difficulty. As for now, it is mostly about finding numbers with same divisors (the bigger the better) until you end up with primes are fairly small numbers. The end game needs some caution, to not run into dead ends. The real challenge I think are these big numbers and finding good pairs amoungst them. Just thinking out loud here, and now I got stuck with my thoughts :-D Will try the daily puzzle tomorrow again for sure!
