After trump is named, the order that players opt to play or opt out is up to you as a house rule. Our variation is 'stick the dealer' which keeps the game moving. I have not seen a tie happen, though it's theoretically possible. You do not need to get zero points exactly win.

Once a player's total reaches 5 points or less, they are no longer allowed to opt out of any hand. If after trump is named, both players opt out, the player who named trump gets a free -5 points. If they opt out, there score is unchanged for the round. A player that did NOT name trump can opt to not play the hand if they don't think they can take at least one trick. Penalty for going set means adding 5 points to your score. The remaining players must take at least one trick in the hand or they are 'set' as well. If you named trump, you must take at least 3 tricks, or you go 'set'. You subtract points based on the number of tricks you take in a hand. All three players start at 25 points with the goal of reaching zero points.
