Whether the lowest or the highest total wins is pre-selected from that label, and you can change it whenever you like. Singles and partners Two, three or four players.

Tap it to change the dealer at any time. Dice No dice on the table? Roll the two in the app. Penalties Penalty rows are marked separately and never inflate the hand count.
