Q: For Rock-Paper-Scissors Showdown, do we throw three times, and if it’s a tie then nobody loses cards?

Or do we keep throwing until someone has won two out of three? If Inflation is in play, do we need to play four rounds? What happens if there’s a tie in that case?

A: You keep playing games until someone has won 2 out of 3. There is no situation where no-one loses cards.

If Inflation is in effect, you would indeed need to play 4 games instead of 3. If that turns out 2-2, keep playing until someone gets a tie-breaking win. Like “sudden death” in an overtime tie situation: whoever scores first wins.
