React to sound. Trust your instincts. Survive the echo.
🕹️How to Play
- 1Watch and listen for audio-visual cues that signal an incoming challenge.
- 2Tap or click in sync with the echo pattern to score points.
- 3Each successful response strengthens the chain and raises the tempo.
- 4Miss a beat and the chain resets — keep the rhythm alive.
📋Rules
- ▸Responses must land within the timing window to count.
- ▸Early or late taps outside the window count as misses.
- ▸Three consecutive misses end the round.
- ▸The tempo gradually increases as your score grows.
💡Pro Tips
- ★Focus on the visual cue, not the sound — sound can be distracting at high tempo.
- ★Relax your hand between cues; tension causes mistimed taps.
- ★At high tempo, anticipate the cue slightly rather than reacting after you see it.
ℹ️About
Echo is a rhythm-reaction game built around the idea that instinct beats planning. Unlike games where you memorise patterns in advance, Echo generates its cues dynamically, forcing you to stay present and responsive rather than rely on muscle memory. The game borrows from the long tradition of reaction and rhythm titles while delivering a browser-native experience with zero load time. Every session is different, making it endlessly replayable. The pulsing audio-visual design is built entirely with the Web Audio API and Canvas 2D — no external assets, no plugins.
