Impostor

The undercover party game — most of you share the word, some of you are faking it.

Impostor (some people spell it Imposter) is Karibu's pass-the-phone undercover party game — a Kenyan social-deduction game in the same family as Spyfall, Undercover and Mr White. Most of your crew shares one Kenyan-flavoured secret word, but hidden undercovers get a similar-but-different word (and don't even know they're faking it), while Mr White gets no word at all. Describe your word, argue it out, and vote the fakes out one by one.

Peek at your card

Describe, don't reveal
Take turns dropping a clue that proves you know your word — without ever saying it outright.
