Colony Flow Level 15 is a puzzle stage that requires you to connect all colonies using a continuous flow path while filling the entire grid.
This walkthrough breaks down the exact solve sequence, starting positions, and the critical moves that prevent dead ends. Level 15 introduces tighter constraints than earlier stages, making it easy to block yourself if you don’t plan your route carefully.
The key challenge is managing the limited space while ensuring your flow path reaches every colony marker without leaving gaps.
Colony Flow! Level 15 Walkthrough
Colony Flow Level 15 is a raccoon pixel-art board where yellow background, white body, cyan face-and-tail stripe, brown eye-mask, and black outline all share one ant hole. The colors must enter the trail in the right order or the thin eye-mask cells get blocked behind waves of white or yellow ants.
Yellow clears the cream-yellow background. White fills the body, face plate, and paws. Cyan completes the stripe across the face and tail. Brown fills the eye-mask band. Black finishes the outline and dark details.
Every color uses the same ant hole and route. Five empty buffer slots above the 3x3 starting grid hold refill stacks as the opening stacks drain. Keeping those spaces free prevents needed colors from being blocked.
How to Solve Colony Flow! Level 15 — Full Solution
Tap the 35 yellow stack at top-left, then the 35 yellow stack at top-middle.
Let the first yellow wave enter the trail before sending the second. Together they clear the cream-yellow background across the top of the frame.
Tap the 35 cyan stack at bottom-left.
Cyan clears the stripe across the raccoon’s face and tail. Hold the 34 brown center stack for now.
Drain the four 35 white stacks one at a time.
Use the stacks at top-right, middle-left, middle-right, and bottom-middle. Let each white wave progress before tapping the next.
Send the 34 brown center stack after yellow and cyan are at least half-cleared.
Brown fills the narrow eye-mask band. Sending it too early stalls the route and blocks later detail waves.
Clear the refill stacks as they rise into the buffer row:
- 17 yellow
- 18 white
- 22 yellow
- 35 white
- 23 brown
Clear these before the smallest detail stacks to keep the five buffer slots available.
Finish the detail and cleanup stacks with single-tap timing:
- 1 black, 6 brown, 4 brown
- 40 cyan, 28 cyan
- 8 yellow, 8 white
- final 1 black
The board clears after the last black outline cell drains.
Common Mistakes to Avoid
- Tapping the 34 brown center stack too early. If brown goes before yellow and cyan are half-cleared, brown ants stall on remaining body cells and block every later dark-detail stack.
- Filling buffer slots with the wrong color. This strands the next refill wave before it can rise into the active row.
- Tapping the right-side white stack before the cyan stripe has started. White ants dump into body cells that cyan still has to clear and stall on the remaining tail tip.
Quick Tips for Colony Flow! Level 15
- Use the paired yellow stacks as the opening wave. The cream-yellow background is the largest region. A continuous yellow run keeps the dirt strip clean for later cyan and brown waves.
- Resist tapping brown before yellow and cyan are half-cleared. The brown eye-mask sits on top of the white body. A premature brown wave blocks every later dark-detail stack.
- Keep the five buffer slots open through the first four beats. New stacks rise into the buffer in sequence. Parking the wrong color in any slot strands the next refill wave.
- Watch the ant hole, not just the stack grid. If a color is stalled near the shared route, wait for it to clear before adding another stack.
