The Da Vinci Code

Players: 2-4.

Objective: Each player has a set of number cards, the goal is to guess the number cards of the opponent.

Props: There are two colors of cards in the game, 13 black and 13 white, each color includes 12 number cards from 0 to 11 (for personal reasons to increase playability, one black and one white number 12 is added) and 1 Joker card (dash card).

1. Place all cards face down, mix and shuffle. Each player draws 4 cards at random (if it is a 4-player game, each player draws 3 cards at random), as their own hand.
2. Each player's hand, the numbers are only visible to themselves, and need to be arranged in order. The order rule is as follows: Arrange the numbers from smallest to largest, and the black cards with the same number are smaller than the white cards. The Joker card can be placed in any position.
3. All players take turns. When it's a player's turn, he must draw a card from the pile first and set it aside (not inserting it into his hand).
4. The player must designate a card that is not revealed from another player, guess the number of this card. He has 13 numbers to guess: 0-11 and Joker.
5. The player who is being guessed must answer truthfully: guessed correctly or guessed incorrectly.
   1. If the player who is guessing guesses correctly, then the guessed card must be revealed to everyone. After that, the player who is guessing has 2 options: ① Continue guessing (i.e., step 4); ② Give up guessing and put the card he just drew into his hand in order, ending his turn, and the next player will perform step 3.
   2. If the player who is guessing guesses incorrectly, then the player who is guessing must reveal the card he just drew to everyone, then put the card into his hand in order, end his turn, and the next player will perform step 3.

【Additional Rules】

If it is a player's turn to act and there are no cards left in the pile, then he does not need to draw a card and can directly guess the card (i.e., skip step 3 and enter step 4). If he guesses incorrectly, then he must choose a card from his hand to reveal and end his turn.

【Winning Condition】

When all of a player's hand cards are revealed, he is out of the game. In the end, the only player with unrevealed cards left will be the winner of the game.
