Ace of Spades
Contributed by Eric J. Egolf (firstname.lastname@example.org)
A very simple game, possibly the simplest in all creation.
Number of players: 1 to many
Step 1: Shuffle and cut the deck.
Step 2: Turn over the top card. If it's the Ace of Spades, you win. If it's not, you give the deck to the player to your left, who repeats from Step One.
Variations: Many variations of this card game exist, including Three of Diamonds, Eight of Hearts, Joker (which is recommended for beginners since the chances of winning are twice as good with each shuffle), and Jack of Clubs, possibly the most exciting of the variants.
