1. When it's your turn, play 1-3 cards face down.
2. If you start, declare what they are (e.g. "PCs"). The next player MUST play cards and claim they are also "PCs".
3. You can lie! Play other cards to get rid of them.
4. Suspect a lie? Tap "Call Liar!" on their turn. If they lied, they play Russian Roulette. If they told the truth, YOU play it.
5. Survive to be the last one standing.
