How to clear Colony Flow! Level 528
Colony Flow! Level 528 is a nested board built around the Yellow and Purple pairs — several colors share tight corridors, so the order you route them is everything. 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 Purple 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 Purple pair before it seals
Watch the Purple pixels crossing the Yellow route near the right side. Clear the Purple pair first — if the Yellow line seals that corridor early, the Purple 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 Purple pair is still reachable before moving on.
- 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
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 528
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 Purple 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 Purple, restart. A fresh board is faster than salvaging a tangled state.
