How should I open Colony Flow Level 31?

Open with the white 8 stack at the far left of the 5-cell top row, then the orange 15 right next to it, and then the dark navy 7 once it rises into the third cell of the top row from the source grid. This drains the white background, the first orange X arm, and the first navy diamond cell together before any large white 30, orange 30, orange 28, or dark navy 25 refill is allowed onto the dirt path. Tap the dark navy 25 stacks, the orange 30 stacks, the orange 28 stack, the white 30 stacks, or the white 25 stacks only after the white 8, orange 15, and dark navy 7 waves have cleared the perimeter of the X.

What breaks when the dark navy 25 stack goes early in Colony Flow Level 31?

The dark navy 25 stack in the second source row uses the same dirt path as the orange 15 stack in the top row, and the four small navy diamond cells plus the central navy diamond only sit in cells that are still open while the orange X arms are draining. If dark navy ants are sent before at least one orange arm cell is open, they stall on the still-empty diamond cells, the orange 28 refill waiting in the third source row cannot rise, and the white 19 refill that has to rise into the top row gets stranded behind active orange and dark navy ants on the perimeter. Tap dark navy 25 only after the orange 15 wave has cleared at least one diagonal arm cell.

Colony Flow! Level 31 Walkthrough

medium 3 colors

Colony Flow Level 31 is a compact 5-cell top row plus 3-by-4 source grid X-shaped celtic-cross board where a soft white background, four thick orange diagonal arms that form an X, four small dark navy diamond accent cells in the quadrants between the X arms, and a slightly larger dark navy diamond at the very center of the X all share the same single ant hole.

Board Notes

Layout: The board opens in portrait view. The top half of the screen holds a pixel-art X-shaped celtic-cross scene: four thick orange diagonal arms form an X, with a small dark navy diamond accent in each of the four quadrants between the arms and a slightly larger dark navy diamond at the very center of the X. The orange X and the navy diamonds sit on a soft white background. Below the dirt strip the working area is a 5-cell top row plus a 3-by-4 source grid underneath. The 5-cell top row opens as white 8, orange 15, empty white buffer, empty white buffer, empty white buffer. The first source row reads white 30, dark navy 25, orange 30, white 25. The second source row reads white 30, dark navy 25, orange 30, white 25. The third source row reads white 30, orange 28, orange 30, white 25.
Goal: Orange cubes from the orange 15 in the top row, the orange 30 stacks in source columns 1-3, and the orange 28 in the third source row must be carried up the dirt path to the four thick orange diagonal arms of the X. Dark navy cubes from the dark navy 25 stacks in source columns 1-2 must be carried up to the four small navy diamond cells between the X arms and the central navy diamond. White cubes from the white 8 in the top row, the white 30 stacks in source column 1, the white 25 stacks in source column 4, and the white 19 and white 6 refill waves must clear the soft white background cells around the X.
Opening: The video opens on the white 8 stack at the far left of the 5-cell top row. White 8 is the smallest numbered stack in the top row and the white background is the largest feature of the pixel art, so opening with white 8 dispatches a white ant up the dirt path and the background cells closest to the ant hole start draining in the first beat. The second confirmed tap is the orange 15 stack in the second cell of the top row, which sends an orange ant up the same dirt path and starts clearing the orange diagonal arm that runs from the upper-left toward the lower-right. The third confirmed tap is the dark navy 7 stack that has now risen into the third cell of the top row from the source grid, which sends a dark navy ant up the same dirt path and starts clearing one of the small navy diamond cells between the X arms. The three empty white buffer slots in the top row (cells 3, 4, and 5 of the very first beat) are kept open so the rising navy 7, white 19, orange 27, orange 16, and navy 29 refills can land cleanly as the source rows drain. The white 30, white 25, orange 30, orange 28, and dark navy 25 source stacks are all held for one beat so the white 8, orange 15, and navy 7 waves can clear the nearest background, arm, and diamond cells before any larger refill is sent.
Danger Zone: This board usually breaks at the dark navy 25 stack in the second source row, second column. The video shows that stack holding a steady 25-count while the orange and white waves clear the perimeter, and if the player taps that dark navy 25 before at least one orange arm cell is open, dark navy ants get stranded on the still-empty diamond cells and the orange 28 refill waiting in the third source row cannot rise. The other trap is firing the white 30 stack in the first source row before the orange 15 has cleared its first arm cell, because white ants use the same dirt path as orange ants and a premature white 30 click strands white ants on the still-empty background cells and blocks the white 25 refill in the first source row that needs to reach the background. Tapping the orange 30 in the first source row while the dark navy 7 wave is still walking the dirt path is also bad, because orange ants share the path with the dark navy ants and stall on the still-empty diagonal arm cells. Letting the orange 28 in the third source row rise into the active row before the dark navy 7 wave is at least half-drained strands orange ants on the still-empty arm cells and blocks the white 19 refill that needs to reach the background.
Mechanics: Level 31 is a multi-stack color-routing board combined with a pixel-art deconstruction goal and a single ant hole, with an X-shaped celtic-cross scene that uses only three color families (white background, orange X arms, dark navy accent diamonds) on a fairly compact 5-cell top row plus 3-by-4 source grid. The 5-cell top row plus 3-by-4 source grid underneath makes this a 17-cell working area with three empty white buffer slots, so almost every tap immediately changes a route. The X pixel art has three main color families (orange X arms, dark navy accent diamonds, white background) plus the late refill waves, and the player has to keep all of those routes staged at once. The 5-cell top row is the active queue that pre-holds the white 8 and the orange 15 from the start, and the 3-by-4 source grid underneath it acts as the supply that refills the active row as stacks are sent. The three empty white buffer slots are the real staging space here, so the very last small white refill, the last small orange refill, and the last small dark navy refill still need a clean delivery after the bottom of the grid looks clear. Compared to Level 30's wide tropical coconut board, the X scene is narrower, has only three color families, and has a white-heavy background that forces the player to keep the empty buffer slots open for the late white refill waves instead of using them as active stack spaces.

Quick Tips for Colony Flow! Level 31 (spoiler-free)

Tap the white 8, orange 15, and dark navy 7 in that order so the white background, the first orange X arm, and the first navy diamond cell start draining together before any large white 30, orange 30, orange 28, or dark navy 25 refill is allowed onto the dirt path.
Keep the three empty white buffer slots in the top row open for the rising dark navy 7, white 19, orange 27, orange 16, and navy 29 refills. The video shows those slots being filled with refills in quick succession, and filling them with a white 30, orange 30, or dark navy 25 click strands the refill waves and leaves the background cells, the X arms, and the diamond cells undrained.
Save the dark navy 25 stacks, the orange 30 stacks, the orange 28 stack, the white 30 stacks, and the white 25 stacks for the mid-to-late game. They are the diamond, arm, and background colors, and the win cue is the empty art canvas, not an empty play area.

How to Solve Colony Flow! Level 31 — Full Solution

Tap the white 8 stack at the far left of the 5-cell top row. White ants walk the dirt path up to the soft white background around the X, and the background cells closest to the ant hole start draining in the first beat. Wait for the first white ants to clear the bottom edge of the art before tapping the next stack.
Tap the orange 15 stack in the second cell of the top row. Orange ants walk the same dirt path and start clearing the thick orange diagonal arm that runs from the upper-left toward the lower-right of the X. White and orange share the path, so leave one beat between them so the background cells closest to the ant hole are mostly drained before the arm cells start clearing.
Wait for the white 8 and orange 15 ant waves to clear the dirt path between the ant hole and the bottom edge of the art. Let the dark navy 7 rise from the source grid into the third cell of the top row, then tap it to send a dark navy ant up the dirt path and start clearing the first small dark navy diamond cell between the X arms. Do not tap the dark navy 25 in the second source row, the white 30 in the first source row, the orange 30 in the first source row, or the orange 28 in the third source row yet.
Tap the white 19 stack that has now risen into the top row, then the white 6 stack that follows it. White ants walk the dirt path and keep clearing the soft white background cells around the X. White shares the path with every other color, so leave one beat between the white wave and the next orange or dark navy refill that rises into the active queue.
Tap the orange 27 stack, then the orange 16 stack, then the orange 30 stack in the first source row, then the orange 28 stack in the third source row, as they rise into the active row. Orange ants walk the dirt path and start clearing the remaining three thick orange diagonal arms of the X. Orange and white share the path, so leave one beat between the orange wave and the next white refill.
Tap the dark navy 25 stack in the first source row, then the dark navy 25 stack in the second source row, as they rise into the active row. Dark navy ants walk the dirt path and start clearing the remaining three small dark navy diamond cells between the X arms plus the central dark navy diamond. Dark navy and orange share the path, so leave one beat between the dark navy wave and the next orange refill.
Wait for the white, orange, and dark navy ant waves to clear the dirt path between the ant hole and the bottom edge of the art. Do not let any white refill rise into the top row during this beat, and do not tap any of the remaining source stacks yet.
Finish by tapping the late white 30, white 25, orange 30, and dark navy 25 refill waves that rise into the three empty white buffer slots in the top row, plus the last small white refill, the last small orange refill, and the last small dark navy refill. White ants close the last background cells, orange ants close the last arm cells, and dark navy ants close the last diamond cells. The X-shaped celtic-cross silhouette is fully cleared once the last cube is delivered into its matching cell and the level banner appears.

Common Mistakes to Avoid

Filling the three empty white buffer slots in the top row with a white 30, dark navy 25, or orange 30 click before the white 8, orange 15, and dark navy 7 waves have cleared the perimeter of the X, which strands dark navy and white ants behind active orange ants on the perimeter and leaves the navy diamond cells plus the white background cells undrained.
Firing the dark navy 25 stack in the second source row before at least one orange arm cell is open, which strands dark navy ants on the still-empty diamond cells and blocks the orange 28 refill in the third source row that needs to reach the X arms.
Tapping the white 30 stack in the first source row before the orange 15 has cleared its first arm cell, which sends white ants across the arm cells that the orange has to clear and stalls them on the still-empty diagonal arm cells at the top of the art.

Frequently Asked Questions

How should I open Colony Flow Level 31?
Open with the white 8 stack at the far left of the 5-cell top row, then the orange 15 right next to it, and then the dark navy 7 once it rises into the third cell of the top row from the source grid. This drains the white background, the first orange X arm, and the first navy diamond cell together before any large white 30, orange 30, orange 28, or dark navy 25 refill is allowed onto the dirt path. Tap the dark navy 25 stacks, the orange 30 stacks, the orange 28 stack, the white 30 stacks, or the white 25 stacks only after the white 8, orange 15, and dark navy 7 waves have cleared the perimeter of the X.
What breaks when the dark navy 25 stack goes early in Colony Flow Level 31?
The dark navy 25 stack in the second source row uses the same dirt path as the orange 15 stack in the top row, and the four small navy diamond cells plus the central navy diamond only sit in cells that are still open while the orange X arms are draining. If dark navy ants are sent before at least one orange arm cell is open, they stall on the still-empty diamond cells, the orange 28 refill waiting in the third source row cannot rise, and the white 19 refill that has to rise into the top row gets stranded behind active orange and dark navy ants on the perimeter. Tap dark navy 25 only after the orange 15 wave has cleared at least one diagonal arm cell.
