来自钟楼百科的介绍：

在很久很久以前，一个叫做鸦木布拉夫的沉睡小镇里，雷雨交加。午夜时分，一阵骇人的惨叫声回荡在那藤蔓覆盖且又错综复杂的乡间小径上。

受到惊吓的镇民们赶往城镇广场查看，他们发现当地的一位说书人被谋杀了，他的尸体被钉在钟楼的时针上，鲜血不断地滴落在下方的鹅卵石上。众人的好奇心开始逐渐转变为恐惧，显而易见，有恶魔正在逍遥法外，它在夜晚杀戮，而在白天化为人形隐匿于镇民之中。

每位镇民都有一些信息，但恶魔和它的爪牙也会散布谎言来混淆视听，萌生猜忌以此来掩盖恶魔的身份。善良的人们会将破碎的信息及时拼凑完整吗？还是说邪恶方会在这座曾经和平的小镇上肆虐横行？

《染》是一款社交游戏，它有关推理与欺骗，谎言与逻辑，谋杀与神秘。游戏支持5至20位玩家进行游戏。在白天时，玩家们以集体讨论或私聊的方式进行交流来收集信息，分享情报，或是散布谎言。在夜晚来临后，玩家们会闭上双眼，恶魔和爪牙则会醒来并在镇上作祟。

每名玩家都有一个独特的角色，它可能会具有强大的能力，或是些需要极力避免的麻烦和惩罚。《染》更多的是一款语言类游戏，在游戏中几乎不需要用到什么道具。玩家们需要依靠自己的智慧，洞察力和无可辩驳的说服力来决定游戏中每个人的生死。

一局《染》通常会进行30到90分钟，稍加尝试，你或许会发现你开始逐渐沉迷于一次又一次的对局中。

Description from boardgamegeek:

In the quiet village of Ravenswood Bluff, ‌a demon walks amongst you...

During a hellish thunderstorm, on the stroke of midnight, there echoes a bone-chilling scream. The townsfolk rush to investigate and find the town storyteller murdered, their body impaled on the hands of the clocktower, blood dripping onto the cobblestones below.

A Demon is on the loose, murdering by night and disguised in human form by day. Some have scraps of information. Others have abilities that fight the evil or protect the innocent. But the Demon and its evil minions are spreading lies to confuse and breed suspicion.

Will the good townsfolk put the puzzle together in time to execute the true demon and save themselves? Or will evil overrun this once peaceful village?

Blood on the Clocktower is a bluffing game enjoyed by 5 to 20 players on opposing teams of Good and Evil, overseen by a Storyteller player who conducts the action and makes crucial decisions.

During a 'day' phase players socialize openly and whisper privately to trade knowledge or spread lies, culminating in a player's execution if a majority suspects them of being Evil. Of a 'night' time, players close their eyes and are woken one at a time by the Storyteller to gather information, spread mischief, or kill.

The Storyteller uses the game's intricate playing pieces to guide each game, leaving others free to play without a table or board. Players stay in the thick of the action to the very end even if their characters are killed, haunting Ravenswood Bluff as ghosts trying to win from beyond the grave.

If you arrive late to a game, you can enter after it's started as a powerful Traveller character with unusual talents and questionable allegiances. Each character comes with their own special ability and no two players in a game are ever the same character.
