How to clear Colony Flow! Level 408
Colony Flow! Level 408 is a nested board built around the Yellow and Cyan pairs — pairs sit close together, but a few routes weave across the board. Most failed runs here happen in the first three moves, so the order below matters more than speed.
- 1
Survey the Yellow lines
Find every Yellow and Cyan pixel before touching anything. A quick scan of where the Yellow corridor can go decides the whole board.
- 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
Route the ${b} pair before it seals
Watch the Cyan pixels crossing the Yellow route near the right side. Clear the Cyan pair first — if the Yellow line seals that corridor early, the Cyan pair is cut off and the run restarts.
- 4
Clear the long edge routes
Edge lines never need the center. Take them while the board is still open, then check the Cyan pair is still reachable before moving on.
- 5
Re-check the ${a} 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
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 408
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 Cyan 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 Cyan, restart. A fresh board is faster than salvaging a tangled state.
