Play NG: Flow Lines Online Free

About This Game

Connect the colors and paint every square in this elegantly minimal line-drawing puzzle. Each board presents pairs of matching dots, and your task is to link each pair with a smooth path that never crosses another line. The real challenge arrives with the finishing rule: the entire grid must fill up, so every route must be planned with total coverage in mind. Hundreds of layouts scale from gentle warm-ups to genuinely demanding tangles. Clean visuals, instant restarts, and pure logical satisfaction make it a perfect pocket puzzle for all ages.

How to Play

Goal: connect every pair of matching dots and fill the whole grid without any overlapping lines. Controls: tap a colored dot, then drag your finger or mouse across adjacent squares to draw a continuous path to its partner. Tip: pair up the longest, most awkward connections first, since short lines flex into leftover gaps easily. Restart instantly whenever two lines accidentally cross.
