About

Echo Pattern

Watch the pattern. Hold it in your mind. Bring it back, one tile at a time. Echo Pattern: Zen Memory is a minimalist pattern-memory puzzle built for quiet focus. A picture appears on the grid, fades away, and you rebuild it from memory — square by square, colour by colour. No noise, no rush, no punishment. Just you and the pattern. A CALM PLACE TO CONCENTRATE Every puzzle is a small picture: a lighthouse, a ladybird, a sunflower, a fox. Watching one resolve under your fingertips is oddly satisfying — and by the time it is finished, you have been fully absorbed for a couple of minutes without noticing. WHAT YOU GET • 200+ handcrafted levels — every one a real picture, drawn by hand, not generated. The grid grows, colours multiply, and the patterns quietly get harder as you go. • A new Daily Challenge every day — one fresh picture, every morning, from a library of 100+. • Endless Mode — patterns generated on the fly, mirrored and symmetrical, that keep growing for as long as you keep up. Nobody has seen the end of it. • Square and hexagonal grids — the honeycomb boards read completely differently, and they will catch you out the first few times. • Up to three colours per puzzle — remembering where a tile goes is one thing. Remembering which colour it was is another. • Three difficulty tiers — Basic, Hard and Challenge, with less time to memorise as you climb. PLAY IT YOUR WAY Five minutes in a queue or a long quiet evening — Echo Pattern fits either. Lose a puzzle and you simply try again; nothing is taken away, no streak is broken, no leaderboard is watching. The only thing you are competing with is your own memory. Turn on the ambient soundtrack for a deeper session, or play in silence. Both work. Free to play, with an optional one-time purchase to remove ads.
