In Double Dealing Shuffle, two players will compete in a sleight of hand shuffling contest. The goal is to hide from your opponent where your odd card out has gone, while not losing track of it yourself and at the same time keeping an eye on your opponent who is trying to do the same thing. The winner of a round takes cards from their deck and gives them to their opponent. Whoever gets their hand down to 6 cards first, wins the game!
(This was the game I made for Button Shy’s “18 of the same card” design challenge)
