Which stack should I lead with in Colony Flow Level 39?

Lead with the green 15 stack at the far left of the 4-cell active row, then the gray 6 in the second cell, then the white 10 in the third cell, and then the red 10 in the fourth cell. This closes the two green leaf clusters, the small gray accent cells, the white inner-petal cells, and the dark red center of the camellia together before any pink petal ring, black outline, yellow background tile, or orange accent color is allowed onto the dirt path. Tap the pink 10, the black 12, the white 15, the orange 20, the yellow 7, the green 8, the yellow 16, the yellow 20, the green 15, the green 2, or the late refill waves only after the green 15 plus gray 6 plus white 10 plus red 10 waves have cleared the top of the camellia.

What breaks when the orange 20 stack goes early in Colony Flow Level 39?

The orange 20 stack in row 2 uses the same dirt path as the green 15 stack in row 1, and the small orange accent cell under the lower-right of the flower only sits in cells that are still open while the green leaf clusters are closing. If orange ants are sent before the leaf clusters are at least half-closed, they stall on the still-empty orange accent cell, the small late orange refill waiting behind them cannot rise, and the pink 12, pink 8, pink 14, and pink 1 refills that have to rise into the refill slot at the right end of the active row get stranded behind active green and orange ants on the dirt path. Tap orange 20 only after the green 15 wave has closed the leaf cells closest to the ant hole.

Colony Flow! Level 39 Walkthrough

medium 8 colors

Colony Flow Level 39 is a camellia-flower board where pink and white petals, two green leaf clusters, a dark-red center, a yellow background, and one small orange accent all share the same ant hole, so the blossom has to open in layers.

Board Notes

Layout: The board opens in portrait view. The top half of the screen holds a pixel-art camellia-flower figure: a wide round blossom with overlapping pink and white petals on a yellow background tile, a dark red/black center with a small white cross highlight, two green leaf clusters on the left and right sides of the blossom, a thin black outline wrapping the entire silhouette, and a small orange accent cell tucked under the lower-right of the flower. Below the dirt strip the working area is a 4x4 source grid of cube stacks. Row 1 (the active row) opens as green 15, gray 6, white 10, red 10. Row 2 reads pink 10, black 12, white 15, orange 20. Row 3 reads green 15, yellow 7, green 8, yellow 16. Row 4 reads yellow 20, green 15, green 2, yellow 16.
Goal: Green cubes from the green 15 stacks in row 1 and row 3 plus the green 15, green 8, and green 2 stacks in rows 3-4 plus the late green 14 and green 2 refills that rise into the active row must fill the two green leaf clusters on the left and right sides of the blossom. Pink cubes from the pink 10 in row 2 plus the late pink 12, pink 8, pink 14, and pink 1 refills that rise into the active row must close the wide pink petal ring around the blossom. White cubes from the white 10 in row 1 plus the white 15 in row 2 plus the late white 8, white 6, white 2, white 9, and white 1 refills must fill the white inner-petal cells and the small white cross highlight in the center. Black cubes from the black 12 in row 2 plus the late black 8, black 6, black 15, black 14, black 9, black 3, and black 2 refills must trace the thin black outline wrapping the flower silhouette. Red cubes from the red 10 in row 1 plus the late red 5 and red 1 refills must fill the dark red center of the blossom. Yellow cubes from the yellow 7, yellow 16, yellow 20, and yellow 16 stacks in rows 3-4 plus the late yellow 14, yellow 16, yellow 10, yellow 5, yellow 9, and yellow 1 refills must fill the yellow background tile and the small yellow accent cells. Gray cubes from the gray 6 in row 1 must handle the small gray accent cells on the petal edges. Orange cubes from the orange 20 in row 2 must fill the small orange accent cell under the lower-right of the flower.
Opening: The first confirmed tap in the contact sheet lands on the green 15 stack at the far left of the 4-cell active row. Green 15 is the highest-count green stack in the top row and the two green leaf clusters on the sides of the blossom are the largest green feature of the pixel art, so opening with green 15 dispatches a green ant up the dirt path and the leaf cells closest to the ant hole start closing in the first beat. The second confirmed tap is the gray 6 stack in the second cell of the active row, which sends a gray ant up the same dirt path and starts closing the small gray accent cells on the petal edges. The third confirmed tap is the white 10 stack in the third cell of the active row, which sends a white ant up the dirt path and starts closing the white inner-petal cells. The fourth confirmed tap is the red 10 stack in the fourth cell of the active row, which sends a red ant up the dirt path and starts closing the dark red center of the blossom. As soon as the first row of the active queue is cleared, the pink 10, the black 12, the white 15, and the orange 20 stacks in row 2 rise into the active queue, and a new refill slot opens at the right end of the active row. The green 15, yellow 7, green 8, yellow 16, yellow 20, green 15, green 2, and yellow 16 stacks in rows 3-4 are all held for one beat so the green, gray, white, and red waves can clear the leaf, edge, inner-petal, and center cells before any larger pink, black, orange, or yellow refill is sent.
Danger Zone: The first real trap is the refill slot that opens at the right end of the active row as soon as the first row of the 4x4 source grid is cleared. The contact sheet shows that refill slot being filled with the late black 8, black 6, black 15, black 14, black 9, black 3, and black 2 refills in quick succession, and if the player taps those rising black refills before the green 15 plus gray 6 plus white 10 plus red 10 waves have closed the leaf, edge, inner-petal, and center cells, the pink 12 and pink 8 refills waiting behind them get stranded behind active black ants on the dirt path and the wide pink petal ring never closes. The other trap is firing the orange 20 stack in row 2 while green ants are still walking the dirt path up to the leaf clusters, because orange ants use the same dirt path as the green ants and a premature orange click strands orange ants on the still-empty orange accent cell and blocks the small late orange refill that needs to reach that accent cell. Tapping the yellow 7 stack in row 3 before the dark red center is at least half-closed is also bad, because yellow ants cross the petal cells that the white and pink stacks still have to fill and stall on the still-empty yellow background tile. Letting the black 12 stack in row 2 rise into the active row before the green 15 plus gray 6 plus white 10 plus red 10 waves have cleared the top of the blossom strands black ants on the still-empty outline cells and blocks the late black 14 and black 9 refills that need to reach the rest of the outline.
Mechanics: Level 39 is a multi-stack color-routing board combined with a pixel-art completion goal and a single ant hole, with a camellia-flower scene that uses seven main color families (pink petals, white inner petals, green leaves, black outline, dark red center, yellow background tile, orange accent) plus a small gray accent on a compact 4x4 source grid. The 4x4 source grid makes this a wide 16-stack working area with one refill slot that opens at the right end of the active row, so almost every tap immediately changes a route. The camellia pixel art has seven main color families plus the small gray accent and the late refill waves, and the player has to keep all of those routes staged at once. The 4x4 source grid is the active supply that starts with green 15, gray 6, white 10, and red 10 in row 1 and refills the active row as stacks are sent. The single refill slot at the right end of the active row is the only staging cell on the board, so the very last black refill, the last pink refill, the last yellow refill, and the small green 2 refill still need a clean delivery after the bottom of the grid looks clear. Compared to Level 35's tall garlic-bulb board and Level 33's hammer board, the camellia scene is wider but has a much more delicate pink-and-white petal ring and a green-on-yellow leaf-and-background contrast that forces the player to keep the refill slot open for the late black and pink refills instead of using it as an active stack space.

Quick Tips for Colony Flow! Level 39 (spoiler-free)

Tap the green 15, gray 6, white 10, and red 10 in that order from the top row before you touch any other color. The two green leaf clusters, the small gray accent cells, the white inner-petal cells, and the dark red center are the four highest features of the camellia, and they have to close together before any pink petal ring, black outline, yellow background tile, or orange accent color is allowed onto the dirt path.
Keep the refill slot that opens at the right end of the active row open for the late black, pink, white, and red refills. The contact sheet shows that slot being filled with refills in quick succession (black 8, black 6, pink 12, pink 8, white 9, white 1, red 5), and filling it with a pink 10, black 12, white 15, or orange 20 click strands the refill waves and leaves the wide pink petal ring, the black outline, and the white inner-petal cells half-empty even when the source grid looks clear.
Save the orange 20 stack in row 2, the yellow 7 and yellow 16 stacks in row 3, the green 15, green 2, yellow 20, and yellow 16 stacks in row 4, and the late refill waves for the mid-to-late game. They are the orange accent, yellow background, second-leaf, and refill colors, and the win cue is the full camellia-flower image, not an empty play area, so the last small pink refill, the last small black refill, the last small white refill, the last small green refill, the last small yellow refill, and the last small red refill still need a clean delivery after the bottom of the grid looks clear.

How to Solve Colony Flow! Level 39 — Full Solution

Tap the green 15 stack at the far left of the 4-cell active row. Green ants walk the dirt path up to the two green leaf clusters on the left and right sides of the camellia, and the leaf cells closest to the ant hole start closing in the first beat. Wait for the first green ants to clear the bottom edge of the art before tapping the next stack. Keep the refill slot at the right end of the active row untouched so the late black, pink, white, and yellow refills can land there.
Tap the gray 6 stack in the second cell of the active row. Gray ants walk the same dirt path and start closing the small gray accent cells on the petal edges. Green and gray share the path, so leave one beat between them so the leaf cells closest to the ant hole are mostly closed before the gray accent cells start filling.
Tap the white 10 stack in the third cell of the active row. White ants walk the dirt path and start closing the white inner-petal cells on the front of the blossom. Green, gray, and white share the path, so leave one beat between the white wave and the next green or gray refill.
Tap the red 10 stack in the fourth cell of the active row. Red ants walk the dirt path and start closing the dark red center of the blossom. Green, gray, white, and red share the path, so leave one beat between the red wave and the next green, gray, or white refill.
Wait for the green 15, gray 6, white 10, and red 10 ant waves to clear the dirt path between the ant hole and the bottom edge of the camellia. Let the pink 10, the black 12, the white 15, and the orange 20 stacks from row 2 rise into the active row. Tap the pink 10 first so a pink ant walks the dirt path and starts closing the wide pink petal ring around the blossom. Then tap the black 12, the white 15, and the orange 20 in that order so the black outline, the white inner-petal refill, and the small orange accent cell start closing in the same beat. Do not tap the yellow 7, green 8, yellow 16, yellow 20, green 15, green 2, or yellow 16 in rows 3-4 yet, and do not let the yellow refill rise into the active row during this beat.
Tap the yellow 7 stack in row 3, second cell, then the green 8 stack in row 3, third cell, then the yellow 16 stack in row 3, fourth cell, as they rise into the active row. Yellow ants start filling the yellow background tile, green ants start closing the second green leaf cluster, and yellow ants close the last yellow background cells around the right leaf. Yellow, green, and pink share the path, so leave one beat between the yellow wave and the next pink or green refill.
Tap the yellow 20 stack in row 4, first cell, then the green 15 stack in row 4, second cell, then the green 2 stack in row 4, third cell, then the yellow 16 stack in row 4, fourth cell, as they rise into the active row. Yellow ants close the last yellow background tile cells, green ants close the last leaf cells on both leaf clusters, and yellow ants close the last yellow accent cells. Yellow and green share the path, so leave one beat between the green wave and the next yellow refill.
Finish by tapping the late pink 12, pink 8, pink 14, pink 1, black 8, black 6, black 15, black 14, black 9, black 3, black 2, white 8, white 6, white 2, white 9, white 1, red 5, red 1, red 20, green 14, green 2, yellow 14, yellow 16, yellow 10, yellow 5, yellow 9, yellow 1, and small orange refills that rise into the refill slot at the right end of the active row. Pink ants close the last wide pink petal ring cells, black ants close the last outline cells, white ants close the last inner-petal and white cross cells, red ants close the last dark red center cells, green ants close the last leaf cells, yellow ants close the last yellow background tile cells, and orange ants close the small orange accent cell. The camellia-flower silhouette is complete once the last matching cube lands and the level banner appears.

Common Mistakes to Avoid

Filling the refill slot at the right end of the active row with a black 8, pink 12, pink 8, or white 9 click before the green 15 plus gray 6 plus white 10 plus red 10 waves have closed the leaf, edge, inner-petal, and center cells, which strands pink and white refill ants behind active black ants on the dirt path and leaves the wide pink petal ring and the white inner-petal cells half-empty.
Firing the orange 20 stack in row 2 while green ants are still walking the dirt path up to the leaf clusters, which strands orange ants on the still-empty orange accent cell and blocks the small late orange refill that needs to reach that accent cell.
Tapping the yellow 7 stack in row 3 before the dark red center is at least half-closed, which sends yellow ants across the petal cells that the white and pink stacks still have to fill and stalls them on the still-empty yellow background tile.

Frequently Asked Questions

Which stack should I lead with in Colony Flow Level 39?
Lead with the green 15 stack at the far left of the 4-cell active row, then the gray 6 in the second cell, then the white 10 in the third cell, and then the red 10 in the fourth cell. This closes the two green leaf clusters, the small gray accent cells, the white inner-petal cells, and the dark red center of the camellia together before any pink petal ring, black outline, yellow background tile, or orange accent color is allowed onto the dirt path. Tap the pink 10, the black 12, the white 15, the orange 20, the yellow 7, the green 8, the yellow 16, the yellow 20, the green 15, the green 2, or the late refill waves only after the green 15 plus gray 6 plus white 10 plus red 10 waves have cleared the top of the camellia.
What breaks when the orange 20 stack goes early in Colony Flow Level 39?
The orange 20 stack in row 2 uses the same dirt path as the green 15 stack in row 1, and the small orange accent cell under the lower-right of the flower only sits in cells that are still open while the green leaf clusters are closing. If orange ants are sent before the leaf clusters are at least half-closed, they stall on the still-empty orange accent cell, the small late orange refill waiting behind them cannot rise, and the pink 12, pink 8, pink 14, and pink 1 refills that have to rise into the refill slot at the right end of the active row get stranded behind active green and orange ants on the dirt path. Tap orange 20 only after the green 15 wave has closed the leaf cells closest to the ant hole.
