Echo Sequence

Watch four neon pads flash, then repeat an ever-growing pattern across ten memory rounds.

How to play Echo Sequence

Watch the full pattern, then repeat it when YOUR TURN appears. The sequence gains one light each round. Clear all 10 rounds before 110 seconds run out; one wrong pad ends the run.

Tap or click the numbered pads, or press 1, 2, 3, and 4. Input is disabled while the pattern plays.
