The app, step by step. The rules are on their own page; this is what you'll see and what to tap.
Someone deals a game and picks Cheat at the top of New game. Say Deal me in; the table deals the whole pack out when everyone has answered.
The middle says what rank the next claim has to be, how big the pile is, and the last claim — who said it and what. Every seat shows how many cards they hold.
Tap up to four cards — they go face down as you tap — then Claim. The claim is the table's rank times the cards you laid; the app says it for you. Nobody sees which cards.
When it isn't your go and someone has just claimed, Cheat! is there. Tap it and the cards turn over in the feed for everyone. Whoever was wrong picks up the pile. The window closes when the next seat lays a card.
Claim your last cards and, if nobody catches you, you've won. The results card shows the order by cards left and the crown on the winner. Rematch deals the same table again.
