Colony Flow! level guide
Colony Flow! Level 518 Walkthrough
Level 518's aquarium scene is dominated by blue-family stacks — blue 36, 40, 32, 43 in Row 1 plus cyan 45 and dark blue 26 behind — all competing for the same central hole, so the opening phase is a sustained single-shade blue drain before pink coral, yellow seahorse, and grey accent stacks can begin.

How to Solve Colony Flow! Level 518 — Full Solution
- Tap blue 36 stack (top row, far left) to begin routing blue cubes through the central hole; allow full clearance before next tap.
- Tap blue 40 stack (top row, second from left) to continue the blue flow; the path is now established and ants move efficiently.
- Tap blue 32 stack (top row, center) followed by blue 43 stack (top row, fourth) in quick succession since the route is clear.
- Tap cyan 45 stack (second row, far left) to merge cyan cubes into the established blue path; the pixel art fish section begins clearing.
- Tap pink 44 stack (second row, second from left) to route pink cubes; the red coral section of the pixel art starts appearing.
- Tap dark blue 26 stack (second row, third) and white 34 stack (second row, far right) to clear the second row completely.
- Tap yellow 30 stack (third row, far left) to route yellow cubes; the orange seahorse section clears from the pixel art.
- Tap grey 20 stack (third row, second from left) followed by pink 45 stacks (third row, positions three and four) to finish the third row.
- Clear any remaining bottom-row stacks, waiting for ant traffic to settle between each tap to avoid path congestion.
Colors in this level:
Blue, Cyan, Dark blue, Pink, Yellow, Grey, White
Common Mistakes to Avoid
- Tapping multiple blue stacks simultaneously creates ant traffic jams at the single hole bottleneck—always clear one stack fully before tapping the next.
- Activating white 34 stack too early fills the buffer slot and blocks routing flexibility for the final color batches.
- Rushing through pink 44 before the blue path clears forces pink cubes to compete for the same route, slowing completion.
Quick Tips for Colony Flow! Level 518 (spoiler-free)
- Read the full board before making your first move so you know which lane is actually under pressure.
- With 7 colors in play, clear the pair with the fewest blockers first so the board opens up instead of tightening.
- Think in chain clears. The best move is the one that sets up the next two moves, not just the quickest current match.
Board notes 5 details
- Layout
- Aquarium pixel art canvas (upper 60%) with underwater scene: large purple-orange fish, green seaweed clusters, red flower coral, orange seahorse, bubbles. Below: Row 1—blue 36, blue 40, blue 32, blue 43, dark blue unlabeled; Row 2—cyan 45, pink 44, dark blue 26, white 34; Row 3—yellow 30, grey 20, pink 45, pink 45; Row 4 partially visible. Single brown hole centered beneath canvas.
- Goal
- Route all colored cube stacks to matching holes to fully erase the aquarium pixel art, leaving a plain white board. The underwater scene includes a large purple-orange fish in upper left, green seaweed clusters, red flower-shaped coral in upper right, orange seahorse in lower center, and scattered bubbles.
- Opening
- Tap blue 36 stack (top row, far left) first—the blue family dominates the board and establishing this path early lets subsequent blue stacks (40, 32, 43) flow efficiently through the same route.
- Danger Zone
- Multiple blue-family stacks (36, 40, 32, 43, 45, 45) compete for the same hole route; tapping several simultaneously causes ant traffic jams at the bottleneck. White 34 stack on second row acts as a buffer blocker if activated too early—save it for after main blue flow clears.
- Mechanics
- Aquarium pixel art clearance with blue-family color variant sequencing; batch clearing required to erase the complex multi-color pixel detail; limited buffer management with white and grey stacks as temporary routing aids.
Frequently Asked Questions
Why are there so many blue-toned stacks?
Level 518 uses blue-family variants (blue, cyan, dark blue) to create the aquarium water and fish scales in the pixel art. Each shade must route separately even though they appear similar.
What does the pixel art depict?
A full underwater aquarium scene with a large purple-orange fish, green seaweed clusters, a red flower-shaped coral, an orange seahorse, and scattered bubbles against a light blue water background — all erased when the level is complete.
Can I tap the pink and yellow stacks before clearing all blue stacks?
Technically yes, but it creates routing congestion at the single hole. The recommended order clears blue-family first to establish an efficient path, then handles accent colors.
