在游戏时长为15到30分钟的推理游戏《Blood Bound》中，玩家们扮演两大派系的成员——兽族的野蛮兽性武士，以及玫瑰派系优美致命的成员，以及人类审讯（玩家人数为奇数时）。通过一个秘密身份伪装自己，他们尝试绑架敌对派系的长者，或者为了自己长者的利益给予他们生命。恶毒的攻击、有目的的轻率言行以及来自于其他人的援助将慢慢地揭开事实：谁为谁而战？谁是长者？

游戏开始时，每名玩家知道三件事情：
● 他是谁，以及他所属的派系。
● 一些其他玩家是他的联盟，同时其他玩家是他和他的派系的敌人。
● 他邻居之一所属的派系，然而有些角色会对自己的派系身份撒谎。

如今，玩家们不得不指出敌人队伍的长者是谁，并抓住他。为了做到这些，玩家们需要攻击、谈判以及推理，一名被攻击的玩家需要展开信息，如他的职衔或派系关系。每名玩家的角色有独特的能力，而且这一能力可以用于且只能在他展示他的职衔的时候使用。例如，暗杀势力玩家遭遇伤害，同时保卫者保护角色选择的一名玩家。

游戏最后，如果你抓住了敌人派系的长者，你就获胜，但如果你抓错了吸血鬼，你就会掉落敌人的陷阱并输掉游戏。

In Blood Bound, a deduction game played in 15-30 minutes, players assume the roles of members of two clans – the brutal, animalistic warriors of the Clan of the Beast and the graceful, deadly members of the Clan of the Rose – and (with an odd number of players) the human inquisition. Disguised by a secret identity, they try to kidnap the Elder of the opposing clan or give their lives for the benefit of their own Elder. Malicious attacks, aimed indiscretions, and assistance from others will slowly uncover the truth: Who fights for whom? And who is the Elder?

At the start of the game, each player knows three things:

Who they are and to which clan they belong
That a few other players are allies, while everyone else is the enemy of both themselves and their clan
The clan to which one of their neighbors belongs – although some characters can lie about their clan identity
Now the players have to figure out who the Elder of the opposing team is (if there is one) and capture him. To do this, players need to attack, negotiate and deduce, with an attacked player being required to reveal information, such as his rank or clan affiliation. Each player has an ability unique to his character, and this ability can be used only at the moment that he reveals his rank. The Assassin forces players to suffer wounds, for example, while the Guardian protects a player of the character's choice.

In the end, if you capture your rival clan's Elder, you win – but if you capture the wrong vampire, you've fallen into the enemy's trap and lose the game.
