How to play Flow

  1. Press New Game for a fresh grid of coloured dots.
  2. Drag from one dot to its matching partner to lay a pipe in that colour.
  3. Pipes cannot cross — and every square must end up filled.
  4. Drag over an existing pipe to redraw it. Connect all pairs and fill the grid to win.

Tips & strategy

  • Start with the dots in the corners and along the edges — they have the fewest routes.
  • Remember you must fill every cell, so a short straight link is often wrong.
  • If a colour boxes another in, redraw the outer one to leave a path.
  • Every puzzle has a full-cover solution, so a dead end means a pipe is taking the wrong lane.

Frequently asked questions

Does every cell have to be filled?

Yes. A finished puzzle connects all pairs and leaves no empty square.

Are all puzzles solvable?

Yes — each is generated by cutting one path that already covers the whole grid, so a complete solution always exists.
