The rules are just like Windows Solitaire, except the deck only has one card in it.
In order to win, you have to put the card on to the piles which start with an ace and stack in order up to the king. Therefore, you need an ace to win. If you don't get one (or even if you do), just click the card to reset the game and try again!
