Solitaire Odds

Ever played Solitaire, Patience or Klondike and wondered what the odds are of moving all of the cards to the Ace piles? I did, and after quite a bit of research a couple of things became quite evident. Firstly, an exact mathematical solution does not exist; and secondly, statistical solutions based on playing a huge number of games were impossible to find.

So… I wrote my own program (Bill's Solitaire Tester) which would play Solitaire lots and lots of times to see if I could come up with an empirical (or brute force) solution myself. Click here to see the results.

The diagram is downloadable in GIF, JPG and PNG formats. Click here to view...

Delaunay Portraits
