Build down alternating colors across eighteen fans with six redeals in hand, and clear the board almost every time: a 99% win rate.

Demon Fan Solitaire is about as forgiving as solitaire gets: you build down in alternating colors across eighteen fans, and with six redeals in your pocket you'll clear the board almost every time. It's played with a single deck, and this one comes down to patience more than luck: it wins about 99% of the time.
Demon Fan plays like Fan Solitaire and La Belle Lucie Solitaire, just with a lot more redeals to work with.
If you enjoy it, the original Solitaire is worth a try too.
If you run into anything odd or have an idea that would make the game better, please contact me.
Have fun playing!
4 foundation piles: Build up in suit from Ace to King.
18 fans: Build down by alternating color. Only one card can be moved at a time, and there are no empty spaces to fill. The first sixteen fans start with three cards each; the last two start with two. Only the top card of each fan shows.
Stock: Six redeals available. Click the green arrow to redeal once you've made every play you can.
There are four foundation piles.
Any ace can move straight to an empty pile. A card can join a foundation pile if it's one rank higher than the pile's top card and the same suit, so the only card that can follow a Q of spades is the K of spades.
The top card of each foundation can be moved back into play if another pile will accept it.
Eighteen tableau piles make up the layout: the first sixteen get three cards apiece, and the last two get two. Only the top card of each pile is dealt face-up; the rest are face-down.
A card can join a tableau pile if it's one rank lower than the pile's top card and the opposite color, so the 8 of diamonds will accept either the 7 of spades or the 7 of clubs.
Cards on the tableau that are not covered by another card can be played onto the foundation or any non-empty tableau pile.
The tableau's empty spaces may not be filled.
Only one card may be moved at a time; sequences are not permitted.
