Eco.
Watch a little sequence. Make it echo. A gentle memory game in two and a half minutes.
HOW TO PLAY / 01
A small echo, one step at a time.
Repeat
When Your turn appears, repeat the sequence by touch, click or keyboard.
Keep going
A mistake shows the correct sequence. Continue with a fresh one and share your result after 150 seconds.
Learn at your own pace
- Try two steps in untimed practice, then repeat three steps.
- Watch and Your turn are separate phases. Wait for the board to invite your answer.
- An error shows a correction, then you can try a fresh sequence. It never removes points.
Reopen Practice from the start, pause or result. Slow presentation is available there and practice never changes your records.
Rules and scoring
A run lasts 2:30 of active play, including presentations, answers, corrections and waits for Ready. Pauses stop the clock. Sequences begin at three steps and grow to four, five and six after 3, 6 and 9 correct sequences. A full sequence earns 10 points per step. There are no speed bonuses or partial points.
Use keys 1–9, or arrows to select a tile and Enter or Space to answer. Holding a key does not repeat an answer. Pause and a hidden tab interrupt the sequence; explicitly resume to see it again from the beginning.
Your best normal score is stored in this browser for Eco rules v1. There are no public rankings, accounts or ads. Practice has no score.
About Eco
What happens when I make a mistake?
You see the expected step and the correct sequence, then continue. The clock keeps running during the correction, but you lose no points.
Does it work without sound?
Yes. Numbers, shapes, phase labels and visual highlights explain every step. Sound is optional. Practice also offers a slower presentation.
What gets shared?
Only points, correct sequences, maximum length and a link to Eco. The image adds a decorative trace of your best sequence. Nothing is posted automatically.
