How to clear Colony Flow! Level 703

Colony Flow! Level 703 is a sprawling board built around the Yellow and Magenta pairs — a layout that punishes guesswork — plan the whole map before dragging. Most failed runs here happen in the first three moves, so the order below matters more than speed.

  1. 1

    Survey the Yellow lines

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

  2. 2

    Open with the ${corner} corner

    Start by dragging the Yellow 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 Magenta pair before it seals

    Watch the Magenta pixels crossing the Yellow route near the left side. Clear the Magenta pair first — if the Yellow line seals that corridor early, the Magenta 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 Magenta pair is still reachable before moving on.

  5. 5

    Re-check the Yellow path

    After the edge work, Yellow 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 advanced board like this one.

Pro tips for Colony Flow! Level 703

Outside in

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

Mind the Yellow corridor

Do not let the Yellow line fill a corridor completely — the Magenta 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 Magenta, restart. A fresh board is faster than salvaging a tangled state.
