What a saved rule set is

The set is a copy. The party keeps its own version of the rules.
The short answer
A saved rule set is a named copy of house rules the host can start from. Your host invites friends. The host invites friends they'd love to have there. One private link per couple. Picking a set copies those lines into this party. Later edits stay on this party unless the host turns on Update the saved set.
House rules are one line each. Blank lines are dropped. Guests agree to the version on this party. If the host changes the text, the version number goes up and anyone who already agreed is asked to agree again.
Adult only. Private by design. You confirm you are 18 or older. The host still checks you in. A private no stays private.
What the copy does
On a new party, Saved rule set starts at scratch when the host has no sets yet. Choosing one fills the house rules box. The note under that menu says the pick copies the set into this event.
Save as a new rule set stores the current lines under a name, up to 60 characters. That new set starts at version 1. The party still has its own text.
Update the saved set appears only when a set is already chosen. It writes the party's current lines back onto that set, and only when the text actually changed. The saved set's own version goes up by one.
What guests agree to
Before the night, the guest confirms they are 18 or older and agrees to the house rules and terms, including that they can always decline and tell the host. Those checks are recorded with a timestamp.
If the host edits the rules later, the guest screen says the host updated the rules and asks them to agree to this version. On a key party or a play party, that agreement comes before they answer the cards. On a speed date, they agree to this version to continue. Empty rules do not ask for a new agreement. Saving the same text again does not raise the version.
A night in Atlanta uses this same agreement. Chicago does too. Those cities have their own pages. The rules still live on the party, not on the city page.
Rules do not pick the match
All mutual-yes matches are revealed by the format the host already chose. Agreeing to the rules does not say yes for anyone. A one-sided yes stays hidden.
A key party shows one Play Partner at the same time, after the host starts the reveal. A play party keeps matches hidden until the host reveals them. A speed date is short rounds, then yes or no.
FAQ
Does editing the party change the saved set?
Not by itself. Later edits stay on this party. Update the saved set writes them back, and only when the text changed.
Do guests agree again after an edit?
Yes, when the text changes. The version number goes up. The screen says the host updated the rules and asks them to agree to this version.
What if the host clears the rules?
Empty rules do not ask for a new agreement. The version does not rise just because the box was cleared.
Is a saved set the same on every city page?
No. A set belongs to the host. Atlanta and Chicago each have a page, and neither page stores the rules.
When do matches show?
All mutual-yes matches are revealed by the format. A key party shows one Play Partner at the same time, after the host starts the reveal. A play party keeps matches hidden until the host reveals them. A speed date is short rounds, then yes or no.
