How to play Neon Flow Lines
Neon Flow Lines is a numberlink-style puzzle played on a glowing grid in the dark. Each level scatters pairs of same-colored neon nodes across the board — connect every pair with a continuous glowing path. Paths can’t cross, overlap, or cut through another color’s nodes, and every cell must be filled when you finish. There are 10 grids from 5×5 up to 8×8, each with at least one perfect solution. Drag from a node to draw; tap a node to wipe its path and retry. Clear a level to earn up to three stars.
Controls
Mouse or touch: press a node and drag across empty cells; lift to finish the path. Drag back over your own path to trim it; tap any node to erase its path. Keyboard: arrows move the glowing cursor, Space starts/stops drawing, R erases the path under the cursor, N/P switch levels, Enter starts from overlays. The ◀ Prev / Next ▶ buttons switch levels anytime — stars are kept.
Tips & strategy
Start with the most trapped pairs — nodes stuck in corners or along edges have the fewest routing options, so lock those paths in first. Leave the center open for flexible colors as long as you can. If a pocket of empty cells can only be reached by one color, route that color through it. Watch the Fill counter — connecting a pair early while leaving orphaned pockets behind means redrawing. Clean solves come from planning a few moves ahead, not from speed.
Scoring
Each level earns up to three stars based on efficiency: zero path restarts for three stars, one or two restarts for two stars, three or more for one star. Par is the full grid fill shown in the HUD. Your 10-level total maxes out at 30 stars, and your best rating per level is always kept — replay any level to improve it.
