Brute force attack has to go through 9 to the 81st power different combinations. Those numbers get pretty big.. :-) At least it's got to have less than 81 zeros!I have become addicted to SoDoku... http://en.wikipedia.org/wiki/Sodoku I have started to create a generator/solver in RPG... Has someone else done this? Gerald
I just snipped some ramblings about it I was about to post.How difficult is it supposed to be? I solved it in fifteen minutes or so. It has what seems to me a straightforward solution (once you solve it) although obviously it is not very obvious.
