: rules
1. Goal
Tap, hold or click the notes exactly on the beat of the track. Each hit scores points, and unbroken streaks build a storm multiplier that brings lightning and thunder.
2. Controls
Glowing rings appear anywhere on the board, each with a larger ring shrinking onto it. Tap or click a ring just as the two circles meet. On a keyboard, press Space to hit the ring that is closest to its beat.
3. Judging and points
Perfect timing is worth 10, good timing 5, and both are boosted by the multiplier. Misses score zero and break the streak.
| Result | Points |
|---|---|
| Perfect | 10 |
| Good | 5 |
| Miss | 0 |
4. The storm multiplier
Every 10 hits in a row add 1 to the multiplier, up to ×4. Each step up sets off a lightning flash and a clap of thunder. A miss or a dropped hold sends the multiplier back to ×1.
5. The track and sound
There are no lives: you play the whole track, about a minute long, and the timer counts down the seconds left. Sound matters here: the beat is your metronome, and the Music button adds a melody layer on top of it.
6. Finishing and registration
At the end of the track you see your score and your record. Registering is a choice; if you register, every round starts with 500 bonus points and your results are kept on the leaderboard. Guests play without the bonus.
7. Fair play
Play by hand with the original game; the terms require it. Points and bonuses are virtual only, with no cash value and no prizes.
