It’s one of the most common and arguably enjoyable card games in existence and is also known as Blitz or Scat.

Thirty one is usually played by at least four players with the object being to obtain a hand with a point value closer to 31 than the hands of your opponents.

Using a standard deck of 52 aces are high counting as 11 and all face cards count as 10. The remainder of the cards are worth their face value.

After three cards have been given to each of the players the remainder of the pack is placed in the middle of the playing table acting as the stock for the game. The top card in the pack is turned over to begin the discard.

All players are trying to collect a hand value of 31 or the closest to it in the same suit. Play continues clockwise around the table until any player knocks or obtains a blitz.
A player who believes their hand is high enough to beat at least one of their opponents, e knocks on the table in lieu of drawing and discarding. All other players, going clockwise from the player who knocked, have one more turn to draw from the stock and discard, or they have the option of keeping all three cards in their hands, known as standing. The round ends when the player to the right of the player who knocked has had his or her final turn. If no one knocks by the time a player exhausts the stock, the round ends in a draw.
