About this game
Reflect. Split. Connect.
ECHO is a minimalist logic puzzle about routing a signal. Place mirrors, angle them, and send the beam. It either reaches every receiver, or it shows you exactly where it went wrong.
No timers. No lives. No punishment. Just a board, a beam, and the quiet satisfaction of a route that finally clicks.
ROUTE THE SIGNAL
Tap an empty cell to place a mirror. Tap it again to rotate it. Press SEND and watch the beam travel, bounce and light up the receivers. Wrong route? Adjust and send again - nothing is lost.
THREE STARS, ONE OPTIMAL ROUTE
Finishing a level is easy. Finishing it in the fewest possible moves is the real game. Every level has a verified optimal solution, so three stars is always possible - and always earned.
MECHANICS THAT BUILD ON EACH OTHER
- Mirrors reflect the beam ninety degrees
- Blockers absorb it completely
- Splitters divide one beam into two
- Portals move the beam while keeping its direction
- One-way gates pass only a beam travelling their way
- Multi-hit receivers need charging from two directions
- Multiple emitters: two signals, one board
Each one is introduced on a board where it is the only thing you have to understand, then combined with everything before it.
36 HANDCRAFTED LEVELS
Three chapters, each teaching a new way to think about the beam. Every board is designed and verified - never randomly generated, never impossible.
DAILY ECHO
One special puzzle every day, the same board for everyone. Build a streak.
BUILT FOR SHORT SESSIONS
A level takes under a minute. The game remembers everything, works completely offline, and never asks you to sign in.
DESIGNED, NOT DECORATED
Dark background. One cyan line. Soft glow. No clutter, no pop-ups begging for attention, no fake urgency. Just a puzzle that respects your time and your screen.
Free to play, with an optional purchase to remove ads.
