About NG: Flow Lines
Flow Lines turns the grid into a network of containers: each colored dot is a source that must pipe a continuous line to its matching sink without crossing another line. Every cell on the board is a potential conduit—once occupied, it rejects any other path. The rule is simple: connect pairs, fill the grid, and never let two flows touch. The puzzle's physics is topological—lines can bend, but they cannot split or share space. Plan your routes so each pair gets a clean, unbroken channel through the whole board.
Flow Lines has that perfect "just one more level" feel. You tap a colored dot, drag to connect it to its matching dot, and fill the grid without lines crossing. The trick is planning your route so every cell gets used without overlapping. It's simple to start but gets cleverly tricky as the boards fill up. There's something deeply satisfying about watching the whole grid connect cleanly.
How to Play NG: Flow Lines
- Tap on a colored dot to select it.
- Drag your finger across the screen to draw a path from the selected dot.
- Connect the path to another dot of the same color to complete a pair.
- Ensure the line is continuous and does not overlap with any other line.
- Fill every square on the grid with a line to complete the level.
Game Features
- Color-matching pairs must be connected without crossing lines.
- Every cell on the grid must be filled by a path.
- Increasing board sizes add complexity as more pairs compete for space.
- No time limit or penalties for wrong moves—undo freely.
- Smooth drag controls for precise path drawing on touchscreens.
Tips & Strategies
- Start with pairs that are far apart—they limit routing options for others.
- Use the board edges as natural boundaries to confine a line.
- If a line gets trapped, undo it early and try a different route.
- Look for cells that can only be reached by one color—fill those first.
- Leave central cells open for lines that need to cross the board.
Frequently Asked Questions
What happens if two lines touch or overlap?
Overlapping lines are not allowed—you must redraw one of the paths to avoid contact.
Can I undo a line after drawing it?
Yes, you can undo any line at any time without penalty.
Do all cells have to be filled?
Yes, the goal is to fill every square on the grid with a continuous line connecting each pair.
Is there a color limit per level?
The number of color pairs increases with difficulty, but each level has a fixed set of matching dots.
Can I play Flow Lines on a desktop browser?
Yes, the game works with mouse drag on desktop as well as touch on mobile devices.
