The Deck and the Deal

Thirty One is played with a standard deck of 52 cards. After shuffling the deck, the dealer passes out three cards to each player one by one faced down. The dealer then places the remaining deck in the center of the table, flips over the top card and places it next to the deck to form the discard pile.

How to Play

Beginning with the person left of the dealer and going clockwise, players draw the top card from either the deck or the discard pile, with the goal of making their hand as close to 31 as possible. After drawing a card, the player must discard a card to end their turn. Only cards of the same suit can count towards 31. If a player has a hand containing a 2 of Clubs, a 5 of Clubs and an Ace of Hearts, for example, their hand is worth 11, i.e. the value of Ace, Clubs value of 7 (2 + 5) is lower and hence doesn’t matter.

Once a player believes their hand is close enough to 31, they can knock on the table. Knocking on the table means that every other player has one more turn. Once everybody finishes their turn, cards are shown. If a player is able to get to the maximum count of 31 i.e Ace and two cards worth ten points (10, J, Q or K of the same suit as ace), they can knock right away which ends the round as well (others don’t get to draw another card) and everyone else loses one point.


The player with the lowest value loses one point. Players start with 3 points and also continue playing when they are at 0 points i.e. they get four chances in total before they are out of the game. If you lose after knocking, you lose two points instead of one. In case of a tie, everyone with the lowest points loses one point. If the knocker ties with someone else for the lowest points, they don’t lose a point as others got another chance to draw an additional card.

The last person left in the game wins.


We support several customizable rules and options so you can play Thirty One exactly how you like or how you grew up playing with your friends and family. In addition to the classic way of playing, we often have new creative options for you to try to spice up the game if you are interested in trying different spins for fun.


Players determine a set amount of points when the game ends.


Players determine a set amount of rounds (also known as hands or deals) that the game will go to (instead of the points selection above).


Players only have a set amount of time to make their turn after which a turn is automatically played for them and the game proceeds: Fast is 7 seconds, Standard is 15 seconds, Slow is 30 seconds, and Very Slow is 60 seconds. Players can also choose to disable the timer, but that is only for private tables.

Three of a Kind

Three of a kind gets thirty points as opposed to standard points rules. So, 888 will get 30 points as opposed to only 8.

Shuffle Pile

Whether to shuffle the pile before reusing it or not (to replenish the deck).
