Each person can only say one sentence per round to describe the word he got (you cannot say the word directly), so that the undercover can not find it, but also to give hints to his companions.

After each round of description, 7 people vote for the person they suspect is an undercover agent.

If there are only three people left (including the undercover) in the end, the undercover will win; otherwise, the others will win.
