Watch. Remember. Redraw.
A path traces itself across a five-by-five grid, then vanishes. Redraw it from memory, cell by cell, in order. Every path you have faced lingers on the board as a faint echo: a memory aid, and interference.
Twelve rounds a day. One attempt each. Everyone gets the same Echo.
The Daily. A new puzzle every day, identical for every player. Paths grow longer as the rounds go on; Clear rounds hand you a blank board and Fog rounds turn the echoes up. Finish and you get a result grid to share.
Endless. Three lives and no ceiling. Paths keep growing until your memory gives out.
Echo is free, and the daily game always will be. Echo+ unlocks the Archive, every past Echo since day one, and your full History with every result grid. Pay once for lifetime access, or subscribe yearly.
Two themes, Ink and Lumen. No ads. Sign in with Apple is optional.
