HIT EVERY BEAT,OWN THESTAGE

Everyone dances the same song at the same time. Every dancer for themselves or split into colour teams (2v2, 3v3 or 2v2v2): the top half of the scoreboard — or the team with the highest total — wins. Let your life bar run dry and it's game over.

Couples only: every team has to be one boy and one girl. Two or three couples dance the same song and the pair with the highest combined score wins. Every match earns Charm, and married couples also earn couple points.

A relay between two teams of 2 or 3. In each stretch one dancer from each side takes the floor while their teammates cheer with gestures — one song per pair, back to back. The team with the most points wins, the losers spin the punishment-costume roulette and the best dancer is crowned MVP.

Every 8 bars a prize note hides an item. Hit it and throw attacks — smoke, whirlwind, speed changes, blindness — at the dancer right ahead of or behind you, or raise a shield to block, pass on or bounce them back. Always every dancer for themselves, and nobody gets knocked out.

Six lanes on S D F J K L instead of four arrows, with charts made for six keys. Only songs that have a 6-key chart can be picked, and records are kept apart from the 4-key ones. Solo or in teams.

Fill your magic bar (three levels) and hit Enter or Space to take a solo of 8, 12 or 18 seconds: every note in it scores 50–100% more. No life bar and no teams — and medals are handed out at the end.

The whole song plays 1.1× to 1.5× faster without changing its pitch. Same scoring, more EXP the faster it goes (up to +30%), and its own win ranking for matches that start with 4 or more players.

Notes come at you down a road in 3D perspective instead of scrolling up the screen. The room master switches it on for the whole room; scoring works just like Normal, solo or in teams.

A set of random notes — 20, 40 or 60 depending on the difficulty — comes reversed, and every player in the room gets exactly the same ones. Read each arrow before you hit it. Scoring works just like Normal.

Join the Competition channel, pay the entry fee and wait for the countdown: the server builds the rooms. Five random songs back to back with your combo carried over; your total decides your place, rank points and a share of the prize pot.

Seven lanes of falling notes with key sounds, like the original O2Jam: pick the 7-KEY tab in the room and play 60+ O2Jam classics. Every key you press plays its own sound — miss and the song breaks.
