Colony Flow Level 166 Walkthrough guides you through one of the trickier stages in this colony-building puzzle game, where efficient pipe placement and resource flow management become critical.
This level introduces tighter space constraints and multiple flow paths that must connect without crossing, making it easy to lock yourself into dead ends if you don’t plan your initial moves carefully.
This walkthrough focuses on the opening pipe sequence that sets up success, the key decision points where most players get stuck, and the exact colony placement order that clears the level efficiently.
You’ll find specific move-by-move guidance for the critical first half, plus troubleshooting tips for the most common blocking patterns that force restarts.
Colony Flow Level 166 Walkthrough
Colony Flow Level 166 clears a red-capped, red-and-blue runner portrait through launch-order routing. The key is establishing the light-cyan perimeter streams first—light-cyan 400 and light-cyan 149—while keeping at least one white buffer pad open for later traffic. Opening the larger yellow and blue groups before the cyan loop is stable clogs the lower crossing and strands fragments around the central hole.
The portrait clears in layers: cyan opens the outside route, yellow removes the upper mass and legs, blue and red strip the runner’s torso and coat, then cream, white, black, and dark groups clean isolated pixels. The level finishes with red 1, dark 2, and yellow 3/2.
How the Level Works
Ants leave the central hole and travel around the outside frame, clearing matching pixels. Five white buffer pads provide staging space, but filling all of them while the cyan and red streams cross the bottom edge leaves no room for later groups.
The visible stacks are cream 23, yellow 45, light-cyan 400, light-cyan 149, pale-yellow 40, black 15, red 25, blue 43, white 44, yellow 50, and yellow 49.
How to Play Colony Flow Level 166 - Step-by-Step Solution
Tap light-cyan 400, then red 25.
Wait for the first ants to leave the hole and spread along the lower frame. The counters fall to roughly cyan 395 and red 22.
Tap light-cyan 149.
Release it after the first cyan/red pair has moved toward the lower perimeter. Let both cyan streams share the outside loop.
Hold blue 43 and the yellow stacks.
Do not open blue 43, yellow 45, yellow 50, or yellow 49 while cyan forms a solid band across the lower edge. Wait for a visible gap and keep at least one white buffer pad empty.
Release the yellow route.
Tap cream 23 and pale-yellow 40, then open yellow 45, yellow 50, and yellow 49 in order. Let each yellow group reach the hole before launching the next.
Clear the runner fragments.
Once the yellow traffic separates, open blue 43 and red 45. Use black 15, dark 20/40, and white 44 to remove isolated shoes, head pixels, and pale fragments.
Finish the remaining stacks.
Release red 1, dark 2, then yellow 3 and yellow 2. Wait for the finalants to complete the perimeter loop before the victory screen appears.
Common Mistakes
- Opening blue or yellow while the cyan streams cross the lower route. This ques fragments over the central hole and blocks the perimeter traffic.
- Filling all five white bufers during the first cyan/red wave. Later groups need staging space; keep at least one pad open.
- Stopping when the runner breaks into small fragments. The level requires red 1, dark 2, and yellow 3/2 before the board empties.
Quick Tips
- Start light-cyan 400 and red 25, then wait for the first ants to leave the hole before adding light-cyan 149.
- Keep one white buffer pad empty while cyan and red traffic moves along the lower edge.
- The runner is not finished when only small fragments remain—follow the end counters before waiting for victory.
