Classic, Futsal, Real Match, Sniper, Headball, Pool, Ice Hockey, Basketball, Volleyball, Tennis and Table Tennis each have their own rank and leaderboard. A futsal specialist climbs the Futsal ladder, a pool player climbs the Pool ladder, and neither has to be good at everything. Chaos and Mini Golf are played for fun and have no rank.
Every room you create is Rated unless you switch it to Casual, and the lobby always tells you whether the next match will count.
