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.

Real player data

Aggregated from 23 personal-best records stored on MIKIRI's own servers (as of 2026-08-07; one record per player, flagged runs excluded). The sample is still small, so read this as where early players are stalling rather than a settled trend.

The median is ROUND 2. Only 0% of players get past ROUND 13 (advanced).

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

What OFFBEAT actually tests

OFFBEAT asks you to catch the offset between a sound and a flash. People automatically bind visual and auditory input into a single event, so a small gap still feels simultaneous. This mode probes where that binding breaks down.

Concentrating on only the eyes or only the ears makes it harder. Pick one as your reference and judge whether the other lands before or after it.

Where people get stuck

Audio setup. Headphones, and especially Bluetooth latency, shift what you perceive. Staying on one setup makes your own progress readable.

Riding the beat. Moving with the rhythm makes offsets feel aligned. Stop moving when you judge.

Second-guessing. On this kind of task the first impression is usually the more accurate one.

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.
