Tagiron (also known as Break the Code) is a popular logic-based deduction game played with a deck of 20 cards. The rules of Tagiron vary depending on the number of players. In a four-player game, each player is dealt four cards, and the remaining four cards, called the target cards, are the goal for players to deduce. When a player makes a “challenge” to deduce the target cards, they secretly look at the hidden cards directly. If a player makes an incorrect challenge, they immediately lose and are eliminated from the game as they gain complete knowledge of the target cards. For this reason, players are limited to a single challenge throughout a game. In this paper, we propose a secure computation protocol using card-based cryptography. This protocol can determine the success or failure of a challenge without revealing the hidden target cards to any player. This innovation opens up new variations of Tagiron that allow for multiple challenges (e.g., up to two challenges), which could potentially enhance gameplay and strategic depth.

摘要

Tagiron (also known as Break the Code) is a popular logic-based deduction game played with a deck of 20 cards. The rules of Tagiron vary depending on the number of players. In a four-player game, each player is dealt four cards, and the remaining four cards, called the target cards, are the goal for players to deduce. When a player makes a “challenge” to deduce the target cards, they secretly look at the hidden cards directly. If a player makes an incorrect challenge, they immediately lose and are eliminated from the game as they gain complete knowledge of the target cards. For this reason, players are limited to a single challenge throughout a game. In this paper, we propose a secure computation protocol using card-based cryptography. This protocol can determine the success or failure of a challenge without revealing the hidden target cards to any player. This innovation opens up new variations of Tagiron that allow for multiple challenges (e.g., up to two challenges), which could potentially enhance gameplay and strategic depth.
