A match happens when two people like each other. Once you match, a chat thread opens for both of you, and you can start talking right away.
If you swipe past someone by mistake, Pearl and above accounts can use Undo to bring the last card back. Free accounts see the paywall if they try.
If a match’s ship is heading to the same port as yours, you will see a banner in the chat thread telling you roughly when and where your ships overlap. It says “looks like,” because ship schedules can shift, and it disappears if the overlap no longer holds.
Either person can end a match at any time by blocking the other. A block closes the chat for both people immediately.
