The two-minute-long, two-player card game Blink bills itself as the fastest game in the world. Without taking turns, players race to empty their hands by matching the color, shape, or number of symbols on their cards in hand to the top card of the two discard piles in the center of the table. As soon as a player lays down one card, they can draw another, up to the hand size of three cards. If both players can't play, they can both draw a card directly onto the discard pile at the same time and then continue play. The first player to empty their hand and draw pile wins.
The rulebook includes variants for three- and four-player games.
