How to beat Colony Flow! Level 406 — full solution
- Tap the Green 55 box on the front row, left. Ants clear outer Green border blocks and start opening the scene.
- Tap the Green 60 box on the front row, second from left, followed by the Dark Green 58 box. These dismantle the lower and outer green layers, exposing the Red hair perimeter.
- Tap the White 8 box, the Red 40 box, and the Dark Green 60 box. Ants clear the white highlights and outermost red blocks around the mermaid's head.
- Tap the Light Blue 25 box and the Light Green 55 box. Ants collect exposed light blue water highlights and bottom tail accents.
- Tap the linked pair of Black 2 box and Red 20 box. Ants clear the exposed red hair border while the Black 2 waits for inner outline details.
- Tap the Light Blue 57 box and the White 6 box as they reach the front row. They clear outer bubbles and chest accents, unlocking access to the yellow face.
- Tap the Yellow 11 box and the Black 3 box. Yellow ants begin carrying the mermaid's face blocks once the red and white edges recede.
- Tap the Red 42 box, the White 2 box, and the Brown 8 box. This strips away the upper hair and frees the central areas.
- Tap the Cyan 39 box and the Yellow 27 box. Yellow ants clear the remainder of the face while cyan collects tail and bubble blocks.
- Tap the Green 20 box, the Dark Green 21 box, and the remaining Green 55 boxes in the back row. Ants strip the final background wall until every block is gone.

Moves that cost you the level
- Tapping the linked Black 2 + Red 20 pair before Red blocks are exposed → the Black 2 box sits idle in a slot while Red cannot advance, clogging two slots immediately.
- Tapping the Yellow 11 box while the mermaid face is still covered by Red and White blocks → the yellow box cannot work and permanently blocks a slot.
Quick tips for Level 406
- Work from the outer frame inward; green borders must clear before red hair and yellow skin can be touched.
- Ensure at least two slots are free before tapping any linked pair so you do not overflow the tray.
Board breakdown5 notes
- Layout
- The picture shows a mermaid on a green background. Below the nest sits a five-slot tray, backed by a stack of boxed ants arranged in rows with links and padlocks.
- Goal
- Clear all coloured blocks from the pixel picture by feeding matching ant boxes into the five slots without stalling all slots.
- Opening
- Start with the exposed Green 55 and Green 60 boxes on the front row. They immediately begin carving away the green frame.
- Trap
- The Yellow boxes are trapped deep beneath Red hair and Green background blocks; activating Yellow early wastes a slot.
- Mechanic
- Linked boxes joined by a red bar enter the slots simultaneously, requiring two available slots.
Level 406 questions
-
What should I tap first on Level 406?
Tap the Green 55 and Green 60 boxes at the front of the stack to start clearing the outer borders.
-
Why are my red or yellow ants not moving?
Ants only pick up blocks from the outer edge. If inner colours are still surrounded by green or red blocks, uncover their edges first.
