Cheat (I Doubt It)

Deal the entire deck evenly among all players.

Play proceeds in rank order; the first player must place one or more cards face-down claiming they are a specific rank, such as 'two threes.'

Each following player must place cards claiming the next rank up, whether or not their cards actually match the claim.

Any player may challenge the previous play by calling 'cheat' if they suspect a lie.

If the challenged cards don't match the claim, the player who lied picks up the entire discard pile; if they were telling the truth, the challenger picks it up instead.

The first player to get rid of every card in their hand without being caught lying wins.
