Shamrocks Solitaire is a classic pile based solitaire card game like Cruel Solitaire, or La Belle Lucie. It has an interesting rule that prevents you from putting more than 3 cards on any given pile. You can build the piles up or down without worrying about the suit. There are four suit piles on the left side of the game screen. Your goal is to build them up from Ace to King by suit.
