Card collection version, for two, three or four players Then all players put their cards on the bottom of their decks and turn up a new card. As in the two-player game, if no one slaps the table, the players can agree that there is no solution. In this version it is possible to bluff by slapping the table when you do not in fact have a solution, in the hope that you will not be selected. If the selected player gives a correct solution, the fourth player must take the four cards if not the selected player must take the four cards. When three players have slapped the table, the fourth player must select one of them. A player who has a solution slaps the table but says nothing. The deck is divided equally between the players. Four Player Gameįour players can play 24 as follows. In the standard game the four numbers must be combined using only the arithmetic operations +, -, ×, ÷, with brackets (, ) if necessary to define the order in which operations are carried out. Players may shuffle or cut their card stacks any time they wish, but must not look at the cards in their stacks. In this case, each player chooses one of their cards to take back, adds this card to the bottom of their stack, and replaces it with a new face up card from the top of their stack. If neither player can make 24, they may agree after a little while that there is no solution. If a player slaps the table and then calls out a solution that is wrong, or cannot immediately give a solution, then this player must take the four cards as a penalty. This process is repeated until one player has no cards. Then each player again places two cards face up and players again try to make 24 from the four numbers showing. If it is correct, the four cards are given to the other player to place at the bottom of his or her stack. The first player to think of a solution slaps the table and calls out the solution. Now each player tries to think of a way to combine the four numbers using only addition, subtraction, multiplication and division to get a result of 24.
