How it works
In NOW, the player follows the selected arrow. In MIRROR, left and right swap. In ECHO, a one-turn delay means yesterday’s arrow becomes today’s action. You win only when the three pieces occupy their destinations simultaneously.
Every level is built on deterministic movement, so the same inputs always produce the same result. All 20 launch levels and 365 season-one daily boards have been checked with breadth-first search that includes ECHO’s remembered input.
Why a daily puzzle?
The daily calendar uses UTC. Everyone opens the same puzzle on the same UTC date. The game keeps your score and streak on your device. Sharing is voluntary, and you never need to create an account.
A few design choices
Short sessions, free access, original board art, keyboard and touch controls, and no pressure to sign in. ECHO³ is designed as a small game that remains pleasant even with sound disabled and reduced-motion settings enabled.
