ECHO
Echo every signal back and keep the streak alive.

About this game
Every move comes back. Drag a ball and it slides one square — then, every three turns, every ball you have moved repeats its move. Forever. Balls smash gems of their own colour, so you are never just solving a puzzle: you are building a machine out of your own past, and then watching it work. Line several balls up to strike on the same beat and the whole board goes off at once. 160 levels, every one of them verified solvable before it shipped, plus a Daily Echo that changes at midnight.

Tips and strategy
- Think in beats, not moves. Three drags from now everything you have moved will repeat, so plan the board on the beat instead of planning your next tap.
- Line several balls up to strike on the same beat. When the whole board fires at once you break far more gems than the same moves spread across separate turns.
- Use WAIT when your balls are already pointed at the right colour. Skipping a turn brings the next beat forward and lets the machine you have built do the work.
- Move only the balls you actually need. Every ball you touch repeats that move for the rest of the level, so a stray early drag comes back every three turns.

Frequently asked questions
- How does ECHO actually work?
- You drag a ball one square at a time, and every three turns each ball you have already moved repeats that move. Balls break gems of their own colour, so your past moves become the solution.
- Is ECHO free to play?
- Yes. It runs in your browser at no cost, with 160 levels and a Daily Echo that changes at midnight, and there is nothing to download.
- What does the brass dial at the top do?
- It counts down to the next beat. When it reaches zero, every ball you have moved repeats its move at once, which is when most of the gems break.
