About Flow Link
Flow Link hands you a dark slate grid scattered with pairs of colored dots and one deceptively simple job: drag a pipe from each dot to its twin. Pipes can't cross, and here's the real catch — connecting every pair isn't enough. The level only clears when every single cell of the board is buried under pipe, so a lazy shortcut that leaves two empty corners means you're redrawing half the puzzle.
That coverage rule is where the game gets interesting. You'll finish a route, spot a stranded pocket of cells, and realize the orange pipe has to take the long way around the edge so the blue one can snake through the middle. Drawing over an existing pipe snips it at the point of contact, which makes rerouting fast and a little ruthless. Undo steps you back, a hint sketches one full solution path, and a soft pop follows every cell you claim.
The first fifteen levels on a 5x5 grid teach the habit of thinking in detours; by the seventies you're juggling ten flows on a 10x10 board. It's a calm, no-timer puzzle for people who like their logic with a bit of sprawl.

How to play Flow Link
Press on a colored dot and drag to draw a pipe through the grid, one square at a time, until you reach the matching dot. Pipes can't cross each other — drawing across another pipe cuts it at that spot, and dragging backward erases your own line. To win, connect every pair of dots and cover every cell of the grid with pipe; the fill percentage in the HUD tells you how close you are.

Tips & tricks
- Corners only have two ways in and out, so route a pipe through each corner early — they're the cells that most often get stranded.
- If a small pocket of empty cells has only one color touching it, that pipe must detour through the pocket; redraw it before touching anything else.
- Long, hugging routes along the walls are usually correct: the pipe whose dots sit near the edge tends to own the border cells.
- Chasing three stars? Aim to draw each flow in a single stroke — count the empty cells between the dots first, then commit.
