A game of information, guessing and lying.

Using poker hands, players declare in turn the best hand they think is present out of all the cards in play. If a player thinks the last poker hand played isn't actually present, they can call bullshit to end the round. Then, all players reveal their cards to verify whether the hand exists or not.

The loser of the round is either:

• the player that got called out on a non-existent hand

• the player that called "bullshit" on a hand that actually existed.

While players can only see their own cards, information from the plays within the round should help in figuring out what other players' cards might be.

But intuition can't beat blatant lies.

And a hand a player thought they lied about might actually exist using others' cards!
