How to play

  1. Click a colored dot to begin a flow of that color.
  2. Click adjacent cells one at a time to extend the flow toward its twin dot.
  3. Flows can't cross — each cell holds only one color.
  4. Fill the entire grid (and connect all pairs) to win; 'Clear' resets paths.

Each color has two dots. Click one dot to start a flow, then click neighbouring cells one step at a time to snake a path of that color across to its twin. Flows can't overlap, and you win when every cell on the board is filled with color.

Frequently asked questions

Do I have to fill the whole grid?
Yes — a true solution connects every pair AND covers every cell with a flow.
How do I restart one flow?
Click 'Clear' to wipe all paths, or click the tip cell again to pause and re-route.
