A match is a set three cards where all the socks are paired up. Goal: spot a match. Socks can be played with others or by oneself; cooperatively or competitively.
Deal out 12 cards face up, in a rectangle. Each player looks for a match. Whoever spots one first, says "Match!" and shows it to everyone. If it's a match, the spotter gets a point, and the three cards are replaced. If it's not a match, the spotter loses a point, and the cards are left on the table.
If all the players agree that there isn't a match, deal 3 more cards. The game ends when the deck runs out. The player with the most points wins.
