How to clear Colony Flow! Level 425

Colony Flow! Level 425 is a spread-out board built around the Orange and Pink pairs — a busier layout where one wrong line can seal two colors out. Most failed runs here happen in the first three moves, so the order below matters more than speed.

  1. 1

    Survey the Orange lines

    Find every Orange and Pink pixel before touching anything. A quick scan of where the Orange corridor can go decides the whole board.

  2. 2

    Open with the ${corner} corner

    Start by dragging the Orange pair in the top-right corner home. That line never blocks another color, and it frees the edge so the inner routes stay open.

  3. 3

    Route the ${b} pair before it seals

    Watch the Pink pixels crossing the Orange route near the left side. Clear the Pink pair first — if the Orange line seals that corridor early, the Pink pair is cut off and the run restarts.

  4. 4

    Clear the long edge routes

    Edge lines never need the center. Take them while the board is still open, then check the Pink pair is still reachable before moving on.

  5. 5

    Re-check the ${a} path

    After the edge work, Orange usually has one clear lane left. Trace it mentally — if another color has grown into it, undo one step instead of forcing it.

  6. 6

    Finish the center last

    Settle the inner pairs once the edges are done. The center needs the most open space, so it always goes last on a intermediate board like this one.

Pro tips for Colony Flow! Level 425

Outside in

Handle outer pairs first, then move inward. It prevents inner pixels from being blocked and works for almost every stage.

Mind the Orange corridor

Do not let the Orange line fill a corridor completely — the Pink pair needs to cross it later on this board. Leave one open cell.

Reset when lost

If you have made four or more moves without a clear plan for Pink, restart. A fresh board is faster than salvaging a tangled state.
