Box Fan takes the Fan layout and demands alternating colors instead, across sixteen tight three-card piles. Medium difficulty, 65% win rate, skill matters.

Box Fan Solitaire takes the Fan Solitaire layout and asks you to build in alternating colors instead. Sixteen small piles fan out across the board, each starting with just three cards, so you're working with tight, shallow stacks from the first move. It's medium in difficulty, with a 65% chance of winning, and how you do comes down to skill as much as the luck of the deal.
Midnight Clover Solitaire plays in a similar style, if you want more of this fan-based layout.

Have fun playing!
4 foundation piles: Built up in suit from Ace to King. The Aces are dealt onto these piles at the start of the game.
16 fans: Build down by alternating color. Only one card can move to the foundations or another fan at a time. Only Kings can fill an empty space. At the start of the game, each pile is dealt three cards face up.
There are four foundation piles.
Each foundation pile is handed an ace at the start.
A card can be added if it's one rank higher than the pile's current top card and the same suit.
So the only card that can follow a Queen of diamonds is the King of diamonds.
The top card of a foundation pile can be moved back into play if another pile will take it.
Sixteen fan piles, each dealt three cards, all face up.
A card can be added to a fan pile if it's one rank lower than the pile's top card and the opposite color.
So the cards that can follow a Queen of spades are the Jack of hearts or the Jack of diamonds.
Any card not covered by another card is free to move to a foundation or another fan pile.
Only Kings can fill an empty fan space.
Only one card can move at a time, there's no moving sequences.
