Colony Flow Level 170 clears a green cactus wearing a red-and-yellow sombrero by building routes in a specific sequence.
The level requires building three top yellow stacks first to establish the perimeter, then working through black, white, green, and pale-yellow routes to expose the final dark center and single green pixel. This walkthrough focuses on the exact build order and route priorities that clear the level efficiently.
You’ll find the specific color sequences, perimeter-first strategy, and the steps needed to reveal and complete the final center section without getting stuck.
Colony Flow Level 170 Walkthrough
Colony Flow Level 170 clears a green cactus wearing a red-and-yellow sombrero. Tap the three top yellow stacks first—yellow 35, yellow 40, and yellow 35—to build the outer perimeter.
Once their counters drop to 2 / 6 / 6 and the ring crosses the lower edge, open black 25 and white 8 to expose the brim and dark side pixels. Route green 35 and green 38 for the cactus arms, then use green 35 / 36 for the central stalk.
Clear pale-yellow 21 and20 for the sombrero brim, keeping one buffer free. Finish with the remaining yellow and black groups, then the late yellow 2 / 6 / 5 counters, the dark sequence 25 → 22 → 13 → 3, and the final green 1 pixel. Wait for the purple border ants to clear before Victory appears.
How to Play Colony Flow Level 170 - Step-by-Step Solution
Tap yellow 35, yellow 40, and the second yellow 35 across the top row.
Let the yellow ants cross the lower edge and establish the outer ring. Wait for counters to reach 2 / 6 / 6 before opening other stacks.
Open black 25 and white 8 once the yellow ring has crossed the bottom.
Black 25 clears dark side pixels; white 8 opens the pale brim route. Keep the top black 30 closed to avoid packing the sombrero approach.
Route the cactus arms with green 35 and green 38.
Once yellow traffic has room, tap green 35 and green 38 for the left and right arms. Use later green 35 / 36 groups for the central stalk and lower sections. Pause if green ants meet the yellow ring at the hole.
Clear the pale-yellow brim with pale-yellow 21 and 20.
Keep at least one white buffer free while black ants circulate. Do not spend all five buffers before the yellow ring empties.
Finish the remaining yellow 35 / 30 and black 30 groups.
The picture should break into a yellow hat band, separated green arms, and a narrow dark center.
Complete the late counters in sequence.
Clear yellow 2 / 6 / 5, then the dark groups: 25 → 22 → 13 → 3. Wait for each group to reach the hole before tapping the next.
Clear the final green 1 pixel.
This isolated piece is the last visible green. Let it leave through the active route without reopening other stacks.
Wait for the board to fully clear.
Purple ants may continue around the border after the cactus vanishes. Do not tap anything until allants, counters, and pixels are gone. The Colony Flow logo appears, then Level 170 Victory screen.
Avoiding Dead Ends
- Do not open black 30 or green arms before the yellow ring crosses the lower hole. Early traffic packs the sombrero route and isolates the central stalk.
- Preserve one white buffer. White 8 and pale-yellow 21 / 20 need staging space when they expose the brim and dark pixels.
- Pause when green ants meet yellow traffic. A solid yellow ring means green 35 and green 38 should wait.
- Do not stop when the cactus disappears. The level continues through dark 25 → 22 → 13 → 3, the final green 1, and the purple border cleanup.
Why Start With the Three Top Yellow Stacks?
Yellow 35, yellow 40, and yellow 35 carry the background and hat perimeter. Letting them fall to 2 / 6 / 6 before adding black or green traffic keeps the central cactus route open and prevents the hole from jaming.
When to Open Black 25 and White 8?
Wait until the yellow ring has crossed the bottom edge and a buffer remains free. Open black 25 first to clear dark side pixels, then white 8 to expose the pale brim without crowding the hole approach.
