Su Doku Puzzles

[DALIEN51]

I have written a Microsoft Access 2000 Su Doku Puzzle solver. It can solve any solvable Su Doku puzzle in under 20 minutes on any reasonable spec pc.

Has anyone else written a Microsoft Access Su Doku solver?

Im interested in what logic you employed.

Su Doku Solver

You got me the chink in my armour....yes I to think 20 minutes its excessive...ive racked my brains for a way of improving the speed but considering the number of combinations it is having to deal with I dont see how!

In fairness this is the time relating to 'Fiendish' puzzles. Mild and Difficult can be solved in around 4 minutes.

Anyone else got a solution? Id be happy to discuss my methodology to anyone who can be bothered to listen lol!

Would love to try on a "hard" one.... to see if my code is "smarter"

Except I made it in Excel, but that doesnt matter (much) I think...
