Create game walks through five short sections. The game: a title, a sport, a format from 1v1 to 5v5 or Custom, and a player capacity, with a live explanation of what the number means – “10 play at once, no substitutes. Extra sign-ups go to a waitlist.” When: date, start time in the venue’s local time, and an optional duration. Where: country and city, which is how players find you, plus the venue name, an optional address and an optional map link. Price: Free or a price per player, with the honest note “For information only. RosterUp does not collect payments.” Notes for players: a description prompting for level, what to bring, how to pay and where to meet. Two switches finish it: I’m playing, which takes the first spot on the roster for you, and Show in Discover, which when switched off makes the game reachable only by link.
