1. Open osu!lazer and choose a PoolRotator lobby matching your mode and preferred difficulty.
2. Use the current Discord status card to join. Its launcher opens the current room in lazer; the official multiplayer page is the fallback. If your browser blocks the launcher, use its retry button.
3. Download or import the selected beatmap. Ready up when you can play.
4. If you join during a match, read the bot's remaining-time message and wait for the next map.
5. Play the round. After completion, use .good, .bad, or .ok to give feedback.

Use .start to request the normal countdown, .wait when you need a little more time, and .queue to see upcoming maps. If you are the only player, ready up for automatic starting; you can also explicitly request .start.

Commands go in lobby chat with a leading dot. Most voting and Mania selection controls require you to be an actual gameplay participant. Spectators do not count as players. See using commands and countdown help.

Follow practical session examples or the Mania style walkthrough. Find a command by name, alias, purpose, or lobby mode in the command reference.
