In Crescent, the goal is to move all the cards from the crescent outer piles to the 8 foundation piles in the middle.
The bottom four foundation piles build up in suit from Ace to King (Ace, 2, 3 … Jack, Queen, King). The top four build down in suit from King to Ace (King, Queen, Jack, 10 .. .3, 2, Ace).
Cards on crescent piles can be moved from one crescent pile to another if they are the same suit and one greater than or less than the top card on the destination pile, wrapping in any direction, including the Aces and Kings.
You can move cards between foundation piles (for example, a 5 on the upper row of foundation piles can be taken off a 6 and then placed on a 4 on the bottom foundation piles) as long as the suit is the same.
If you move all the cards from the crescent pile, you can't place a card into an empty space. Also, you cannot take the starting (bottom) cards from the foundation piles.
Hint and shuffle
The Hint button will show available moves one by one. If you find yourself out of moves, you can use the Reshuffle button three times per game to reallocate cards in crescent piles.
