As of now, joining the weekly multiplayer lobbies requires participants to download and install osu!(lazer).
Every 2 weeks of a season, a single playlist lobby is opened. Everyone can participate for the two weeks.
Each playlist lobby provides a predetermined playlist of beatmaps.
Each playlist contains an even distribution of Hard, Insane, and Expert beatmaps.
Each playlist corresponds with the letter assigned to each 2 weeks. Therefore, each playlist gets replayed once during a season.
Within a playlist lobby, everyone competes towards a room-specific leaderboard.
Only the best score results on each beatmap within the playlist are summed up to create a weekly ranked score for each player.
Each beatmap of a playlist counts equally to the leaderboard score.
The individual beatmap score is based on osu!(lazer)'s scoring system.
Once a playlist lobby concludes, the weekly ranked score of each participant of the room is added to the seasonal leaderboard.
