RHYTHM TIMING · 15 ROUNDS
Follow four evenly spaced pulses, then tap exactly when the missing fifth beat should land.
Complete 15 rounds across slow, medium, and fast tempos. Every attempt advances.
READY?
The game gives you beats 1–4. You provide beat 5.
Keyboard: Space or Enter · Touch or mouse: use the large TAP button.
Sound starts with the game. Visual pulses always remain available.
HOW TO PLAY
Start a round and focus on four evenly spaced sound and light pulses.
Keep the interval in your head after the fourth pulse.
Press Space or Enter, or tap the large button, when beat five should arrive.
TEMPORAL ANTICIPATION
Instead of reacting after a cue, you predict when the next cue belongs. The task combines interval tracking, attention, and precisely timed movement.
The standard sequence balances five slow, five medium, and five fast rounds. Audio hardware and display refresh can affect timing, so compare runs on the same device.
READ YOUR RESULT
Timing error is the absolute distance from the expected fifth beat. Standard mode counts an attempt within 180 ms as on beat and labels wider misses as early or late.
Endless mode begins with the same fair window, then gradually tightens toward 90 ms. The first miss or timeout ends the run.
QUESTIONS
In standard mode, landing no more than 180 ms before or after the expected fifth beat counts as on beat.
Early means you responded before the expected beat; late means you responded after it. The displayed number is the absolute timing error.
Yes. Each beat has a synchronized visual flash. Sound improves the rhythm experience but is not required to play.
The tempo continues to vary while the on-beat tolerance gradually shrinks. Your first off-beat response or timeout ends the run.
