FreeCell
I believe most of you have played the card game FreeCell . I have played a hundred games of it , and I believe it's always solvable. I wonder is there a way to prove it.

Re: FreeCell
Actually there are some unsolvable games (although they are a "set of measure zero"). Here is a proof.

Re: FreeCell
Freecell is frustrating, so I play foolproof games instead. LoL~

Re: FreeCell
An easy way to see 2 unsolvable ones: Use the "Select Game" option and when it asks you to enter a number between 1 and 1000000, enter -1 or -2 instead.
