Ladybug is a solitaire game with enough strategy to make it so that experienced players will win more often than inexperienced players. It is rather simple and easy to learn, but quite difficult to win.
The object of Ladybug is to make seven complete slots of exactly four cards each, the four cards summing to 10. Aces are worth 1 point, number cards are worth their face value, face cards are worth 0 points, and 10s are wild and can be any value between 0 and 10. To begin the game, seven cards are dealt face up to start the seven slots. The remainder of the deck then becomes the stock pile. Each turn, three cards are dealt from the stock pile so that only the top one can be seen. The top card of each deal must be used (placed on a slot). The other two cards are optional. A card may not be played on a slot that would make the sum be greater than 10, a slot that already has four cards, or a slot with three cards that would make the sum not equal 10. A player wins if all seven slots have exactly four cards each, summing to 10.
