About Echo Flow
Echo Flow is a puzzle game built around a single elegant idea: light travels along the connections between nodes, and the order in which sources are placed determines everything. Each new source starts its own wave, signals spread one step at a time, and when two signals arrive at the same node simultaneously, the color with the higher number wins. Short lessons introduce the rules as the puzzles progress, so the logic unfolds naturally rather than all at once.
Some levels add a color target on top of the basic goal, requiring a specific number of nodes to end up in a particular color by the time the whole network is lit. With a strict move limit governing every attempt, each placement decision carries real weight.
How to Play Echo Flow: Light the Whole Network
The goal in every puzzle is to light the entire network within the allowed number of moves. Select a dark node to place a source there; that source lights only its own node at first, then existing signals spread one step along the connections with each subsequent placement. When signals from different sources reach the same node at the same time, the node takes the color assigned the higher number.
If a level shows a color target, that condition must also be satisfied by the time the last node is lit — the attempt ends the moment the whole network is illuminated. To correct a mistake, use the back arrow to undo a single move, or use the circular arrow to restart the puzzle from the beginning.
