Echo

Every move you make comes back to you. Drag a ball across the board and it slides exactly one square. That part feels simple enough. Then the twist lands. Every three turns, each ball you have already moved repeats the move it made before. The board does not forget. It replays your history back at you, whether you are ready for it or not.

Balls smash gems that share their colour, so clearing the field is only half the story. You are never just solving a puzzle in front of you. You are building a machine out of your own past, then standing back to watch that machine run. A move you made ten turns ago can return at the worst possible moment, or the best one, depending on how well you planned ahead.

Line several balls up so they strike on the same beat and the whole board goes off at once. That is where the real satisfaction lives. Timing becomes everything. You learn to think in rhythms, to count turns, to set up chain reactions that only exist because you remembered what you did three moves back. NAJOX built this around that single idea, and it holds up across every stage.

There are 160 levels in total, and every one of them was verified solvable before it ever shipped. No dead ends, no impossible boards, just carefully designed problems that reward patience and foresight. On top of that, a Daily Echo arrives and changes at midnight, giving you a fresh challenge tied to the calendar. Come back tomorrow and the puzzle will not be the same one you left behind.
