Colony Flow! Level 409 Walkthrough
Level 409 depicts a hedgehog resting on a grassy lawn with red berry bushes against a light blue sky. Success relies on peeling the outer foliage and sky to collect keys before releasing deep body colours. The main trap is committing body boxes early while their blocks remain fully covered.

How to beat Colony Flow! Level 409 — full solution
- Tap Yellow 15 (row 1, leftmost) and Red 38 (row 1, second from left). Yellow ants target exposed snout pixels while red ants strip the berries in the upper-right foliage, using two slots.
- Tap Green 35 (row 1, third from left) and Black 40 (row 2, second from left). Green ants clear the top leaves and black ants remove the hedgehog's upper spines, opening room in the stack.
- Tap Yellow 14 (row 2, third from left) into the fourth slot. It chips away at the creature's snout and paws, carving toward the cyan key icon on the lower-left grass.
- With the cyan key collected, tap the unlocked Cyan box (row 1, rightmost) and Light Blue 50 (row 2, rightmost). They strip the upper sky perimeter while Black 40 and Yellow 15 finish and free two slots.
- Tap Green 35 (row 3, leftmost) and Yellow 24 (row 3, second from left). Green ants strip the right foliage to reach the pink key icon embedded in the leaves, leaving three slots occupied.
- Tap the unlocked Pink box (row 2, leftmost), Green 50 (row 3, rightmost), and Black 40 (row 3, third from left). They strip the foliage and lawn, exposing the yellow key beneath the creature.
- Tap the linked Light Blue 45 pair (row 4 and row 5, leftmost), Green 35 (row 4, third from left), and Green 15 (row 4, rightmost). They consume the remaining sky and ground, leaving only the creature's core body.
- With the yellow key collected, tap the unlocked Yellow box (row 4, second from left), Light Blue 45 (row 5, second from left), Black 38 (row 5, third from left), and Purple 34 (row 5, rightmost). They clear the remaining creature blocks until Black 1 finishes the final pixel.

Moves that cost you the level
- Tapping Black 40 (row 2, second from left) before Red and Green clear the perimeter → black spines are shielded by grass and sky, causing Black 40 to stall in a slot.
- Sending the linked Light Blue 45 pair into the slots when only one slot is empty → linked boxes require two vacant slots simultaneously, preventing the tap from registering.
Quick tips for Level 409
- Target the pixel boundary surrounding key icons to unlock blocked stack lanes as early as possible.
- Always reserve two open slots before tapping the linked Light Blue 45 boxes at the bottom-left of the stack.
Board breakdown5 notes
- Layout
- A 500-block pixel picture sits at the top showing a hedgehog among bushes and sky. Below the nest are five slots and a stack containing five rows of four boxes each.
- Goal
- Clear all 500 blocks from the picture using 20 ant boxes without jamming the five slots. There is no timer.
- Opening
- Yellow 15 and Red 38 are safe initial taps because yellow snout pixels and red berries are immediately exposed on the outer edges.
- Trap
- Tapping Purple 34 or Black 38 from the bottom row prematurely stalls them in slots because their pixels form the interior of the hedgehog and cannot be reached until the outer layers vanish.
- Mechanic
- Coloured padlocks on stack boxes require freeing their matching key icons embedded within the picture's block layers.
