How to play NeonWire

NeonWire is a neon connect-and-fill puzzle. The goal is simple: link every pair of same-color light nodes with non-crossing paths until the whole grid is filled. There is no timer and no game over — take your time. This guide walks through the rules and the two mechanics that set NeonWire apart from a plain flow-style connect puzzle.

The basics

1. Read the board. Each color has exactly two glowing nodes. Empty cells are waiting to be filled; dark cells (obstacles) can never be entered.
2. Drag to connect. Press one node and drag along adjacent cells — up, down, left or right — to the matching node, then release. Paths are straight only; no diagonals.
3. Keep paths apart. In the final solution each cell belongs to one path. Dragging over another color cuts its line, so you will need to redraw it.
4. Fill the grid. A level is solved when every color is connected and every open cell is covered. No empty cells left.
5. Reset anytime. Tap a path's endpoint to clear that color, or use Reset to clear the whole level.

Directional current (⚡)

On some levels endpoints carry a polarity: one is a source (+) and one is a sink (−). The light has to flow from the source to the sink, so you decide which end to start drawing from. If a level has arrow cells, your path may only pass through them in the direction the arrow points — going against it is blocked instantly while you draw. This adds a planning layer that a simple undirected connect puzzle does not have.

Energy budget & star rating (🔋)

Every level has a par step count — the efficient number of cells to draw through. Finishing earns at least one star; solving at or under par earns three. Because steps are a visible resource, there is always a reason to come back and beat your own best score. Some hard levels cap your energy, so efficient routing matters even more.
