OFFBEAT (Rhythm Sense Test)

In OFFBEAT, dots on the board tick one after another in a steady rhythm — except one, whose timing is off. Your ears catch the hiccup (“tick, tick, ti-tick”), your eyes catch which dot flashed at that moment. Tap it.

It's a genuine audio-visual team effort: hearing detects when, vision locates where. As rounds progress the offset shrinks from 35% of a beat down to 10%, approaching the limits of human timing perception. 🔊 Sound on is strongly recommended.

How to play

1. Enter a username and pick OFFBEAT (somewhere you can play sound)
2. Dots tick in sequence — listen through one full loop first
3. When you hear the hiccup, catch which dot flashed
4. Tap it within three loops. Two lives — how far can you go?

Difficulty

Each round adds dots (5→12), raises the tempo and shrinks the offset from 35% to 10% of a beat. Late-game offsets are around 40 milliseconds — barely perceptible without good ears.

Tips

• Soften your gaze over the whole board and let your ears lead — chasing dots one by one is too slow
• Offsets come in two flavors: early (ti-tick) and late (tick…tick). Learn to tell them apart
• Muted play works but feels ~1.5× harder. It's worth finding somewhere with sound

FAQ

Q. Is OFFBEAT free?

A. Completely free, no signup. Earphones recommended.

Q. Can I play without sound?

A. Yes — the visual timing alone is enough to solve it — but it gets much harder. Sound is the intended way to play.

Q. Do I need musical training?

A. Early rounds use a 35% offset that anyone can hear. Musical ears start paying off in later rounds.

Q. What round counts as good?

A. Round 6+ means offsets below 15% — solidly advanced territory.
