Moriarty has planted a bomb in the heart of Big Ben which he intends to detonate, while Sherlock rushes to defuse it.

At the start of the game, you secretly discover whether you belong to Sherlock or Moriarty, and try to identify your partners without being unmasked by your opponents. In turn, choose a cable to cut in another player’s house and, depending on your team, try to defuse or detonate the bomb.

Sherlock’s team wins the game if they manage to defuse the bomb, while Moriarty’s team wins the game if they manage to detonate the bomb that will destroy Big Ben.
