Which stack should I lead with in Colony Flow Level 45?

Lead with the green 13 stack in the first cell of the 5-cell active row, then the white 27 stack in the second cell, then the black 33 stack in the third cell, then the purple 10 stack in the fourth cell. This dispatches the green, white, black, and purple ants up the dirt path in that order and closes the green corner lights, the white star cells, the dark monitor outline, and the purple banner together before the three red 30 stacks in source row 1 are allowed onto the dirt path. Tap the three red 30s in source row 1 only after the four active row waves have cleared, and tap the black 45, red 84, blue 38, green 25, blue 35, blue 45, green 35, and red 45 source stacks only after the matching active row wave has cleared.

Why should I hold the three red 30 stacks in Colony Flow Level 45?

The three red 30 stacks in source row 1 use the same dirt path as the green 13, white 27, black 33, and purple 10 active row waves, and the red wall frame around the monitor only sits in cells that are still open while the green corner lights, the white star cells, the dark monitor outline, and the purple banner are still closing. If red ants are sent before those four active row waves have at least started closing their color regions, the red ants stall on the still-empty wall frame cells, the red 84 in source row 2 plus the red 45 in source row 4 waiting in the active queue cannot reach the rest of the wall and the small red accent strip, and the late small red refills that have to rise into the empty white buffer pad get stranded behind active green, white, black, and purple ants on the dirt path. Tap the three red 30s in source row 1 only after the four active row waves have cleared the perimeter of the streaming room.

Colony Flow! Level 45 Walkthrough

medium 6 colors

Colony Flow Level 45 is a streaming-room board where the green corner accents, white monitor stars, dark monitor outline, purple banner, red frame, and blue screen all share one ant hole, so the active-row opener has to clear before the heavy red wall wave starts.

Board Notes

Layout: The board opens in portrait view. The top half of the screen holds a pixel-art game-streaming room / arcade: a small cluster of green corner lights in the upper-left next to a small yellow star, a chunky red and dark-red wall frame around a wide blue monitor / window, a small red lower-band accent strip, several white star cells inside the monitor screen, a few purple and black outline cells wrapping the monitor and the wall frame, and a pink/red banner stripe along the very bottom of the art. Below the dirt strip the working area is a 5-cell top active row plus a 4-row, 3-column source grid. The 5-cell top active row opens as green 13, white 27, black 33, purple 10, empty white buffer pad. Source row 1 reads red 30, red 30, red 30. Source row 2 reads black 45, red 84, blue 38. Source row 3 reads green 25, blue 35, blue 45. Source row 4 reads green 35, red 45, with the third cell of source row 4 still hidden by the dirt strip.
Goal: Red cubes from the three red 30 stacks in source row 1, the red 84 in source row 2, the red 45 in source row 4, plus the late red refills that rise into the active row must fill the red wall frame and the small red lower-band accent strip. Green cubes from the green 13 in the active row, the green 25 in source row 3, the green 35 in source row 4, and the late green refills must close the small green corner lights and the green wall highlights. White cubes from the white 27 in the active row, the late white refills that rise into the empty buffer pad, and the white cells that surface from the source grid must fill the white star cells inside the monitor screen and the white highlight cells on the wall. Black cubes from the black 33 in the active row, the black 45 in source row 2, and the late black refills must trace the dark outline wrapping the monitor and the red wall frame. Purple cubes from the purple 10 in the active row plus the late purple refills must fill the small purple accent cells along the lower banner. Blue cubes from the blue 38 in source row 2, the blue 35 in source row 3, the blue 45 in source row 3, and the late blue refills must close the blue monitor screen.
Opening: The run opens with the green 13 stack in the first cell of the 5-cell active row. Green 13 is the smallest numbered stack in the active row and the green corner lights are the smallest color region at the top of the art, so opening with green 13 dispatches green ants up the dirt path in the first beat and the nearest green corner cells start closing immediately. The second confirmed tap is the white 27 stack in the second cell of the active row, which sends white ants up the same dirt path and starts filling the white star cells inside the monitor screen. The third confirmed tap is the black 33 stack in the third cell of the active row, which sends black ants up the same dirt path and starts drawing the dark outline wrapping the monitor and the red wall frame. The purple 10 in the fourth cell of the active row is held for one beat so the green, white, and black waves can clear the perimeter of the streaming room before the purple banner accents are touched. The empty white buffer pad in the fifth cell of the active row is kept open so the rising source refills (the red 30 wave from source row 1, the red 84 from source row 2, the blue 38 wave, and the late white, green, and black refill waves) can land cleanly as the active row drains. The three red 30, black 45, red 84, blue 38, green 25, blue 35, blue 45, green 35, and red 45 source stacks are all held for one beat so the green 13, white 27, and black 33 active row waves can clear the perimeter first.
Danger Zone: Most failed runs start at the purple 10 stack in the fourth cell of the 5-cell active row. The purple banner cells along the lower edge of the art are the smallest color region in the picture besides the green accent cells, and if the player taps the purple 10 before the green 13, white 27, and black 33 waves have cleared the perimeter of the streaming room, purple ants cross the wall frame that black still has to outline and stall on the still-empty banner cells, blocking the late purple refills that need to close the banner stripe. The other trap is firing the three red 30 stacks in source row 1 while green and white ants are still walking the dirt path up to the small green corner accents and the white star cells, because red ants use the same dirt path as the green and white ants and a premature red click strands red ants on the still-empty red wall frame cells and blocks the red 84 in source row 2 plus the red 45 in source row 4 that need to close the wall and the small red lower-band accents. Tapping the black 45 in source row 2 before the red wall frame is at least half-closed is also bad, because black ants share the dirt path with red ants and stall on the still-empty outline cells. Letting the blue 38 in source row 2 rise into the active row before the white star cells in the monitor are mostly closed strands blue ants on the still-empty monitor screen cells and blocks the blue 35 plus the blue 45 in source row 3 that need to close the rest of the monitor.
Mechanics: Level 45 is a multi-stack color-routing board combined with a pixel-art completion goal and a single ant hole, with a game-streaming-room scene. The 5-cell top active row plus the 4-row, 3-column source grid makes this a tall 17+ stack working area with exactly one empty white buffer pad, so almost every tap immediately changes a route. The streaming room pixel art has six main color families (red wall frame and a small red lower-band accent strip, green corner lights and wall highlights, white star cells and monitor highlights, the dark outline wrapping the monitor, the purple banner stripe, and the blue monitor screen) plus the late refill waves, and the player has to keep all of those routes staged at once. The 5-cell active row is the queue that pre-holds the green 13, white 27, black 33, and purple 10 from the start, and the 4-row, 3-column source grid underneath it acts as the supply that refills the active row as stacks are sent. The single empty white buffer pad is the only true staging space here, so the last small red, white, green, black, blue, and purple refill waves still need a clean delivery after the bottom of the source grid looks clear. Compared to Level 35's garlic-bulb board, this streaming-room scene is shorter on the source grid but adds a much larger red wall frame plus a small red lower-band accent strip that forces the player to drain the three red 30 stacks in source row 1 first before any blue monitor refill is allowed onto the dirt path.

Quick Tips for Colony Flow! Level 45 (spoiler-free)

Tap the green 13, white 27, black 33, and purple 10 in that order from the active row before you touch any source row stack. The green corner lights, the white star cells, the dark monitor outline, and the purple banner are the four highest-traffic color regions on the streaming room, and they have to close together before the three red 30 stacks in source row 1 are allowed onto the dirt path.
Treat the active row as the opener queue and the 4-row, 3-column source grid as the supply. The active row has exactly one empty white buffer pad in cell 5 at the start, so the only way to free a slot for a rising refill is to drain an active row cell. Tap the three red 30s in source row 1 only after the green 13 wave has cleared, the black 45, red 84, and blue 38 in source row 2 only after the white 27 wave has cleared, the green 25, blue 35, and blue 45 in source row 3 only after the black 33 wave has cleared, and the green 35 plus red 45 in source row 4 only after the purple 10 wave has cleared.
Save the empty white buffer pad in the fifth cell of the active row for the late cleanup refills. The video shows that pad being filled with rising small white, green, black, purple, and blue refills in quick succession. Filling it with a red 30, black 45, or blue 38 source click strands the refill waves and leaves the white star cells, the green highlights, the dark outline, the purple banner, and the last blue monitor cells empty.

How to Solve Colony Flow! Level 45 — Full Solution

Tap the green 13 stack in the first cell of the 5-cell active row. Green ants walk the dirt path up to the green corner lights at the top-left of the streaming room, and the nearest green corner cells 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. Do not tap the white 27, black 33, purple 10, or any source row stack yet.
Tap the white 27 stack in the second cell of the active row. White ants walk the same dirt path and start filling the white star cells inside the blue monitor screen. Green and white share the path, so leave one beat between them so the green corner lights are mostly closed before the white star cells start filling. Do not tap the black 33, purple 10, or any source row stack yet.
Tap the black 33 stack in the third cell of the active row. Black ants walk the dirt path and start drawing the dark outline wrapping the monitor and the red wall frame. White and black share the path, so leave one beat between the white wave and the black wave so the white star cells are at least half-filled before the outline starts drawing. Do not tap the purple 10 or any source row stack yet.
Tap the purple 10 stack in the fourth cell of the active row. Purple ants walk the dirt path and start closing the small purple accent cells along the lower banner stripe of the streaming room. Black and purple share the path, so leave one beat between the black wave and the purple wave so the outline is mostly drawn before the banner starts filling. Do not tap the empty white buffer pad in cell 5 of the active row, and do not tap any source row stack yet.
Tap the red 30 stack in the first cell of source row 1 as it rises into the active row, then the red 30 in the second cell, then the red 30 in the third cell. Red ants walk the dirt path and start filling the large red wall frame around the monitor and the small red accent strip along the lower band. Red shares the path with green, white, black, and purple, so leave one beat between each red wave so the purple banner cells are mostly closed before the red wall frame starts filling. Do not tap the black 45, red 84, blue 38, green 25, blue 35, blue 45, green 35, or red 45 in source rows 2, 3, and 4 yet.
Tap the black 45 stack in the first cell of source row 2, then the red 84 stack in the second cell, then the blue 38 stack in the third cell, as each one rises into the active row. Black ants close the last dark outline cells wrapping the monitor, red ants close the rest of the red wall frame and the rest of the red accent strip, and blue ants start filling the blue monitor screen. Black, red, and blue share the path, so leave one beat between each wave so the red wall frame is at least half-closed before the blue monitor screen starts filling. Do not tap the green 25, blue 35, blue 45, green 35, or red 45 in source rows 3 and 4 yet.
Tap the green 25 stack in the first cell of source row 3, then the blue 35 stack in the second cell, then the blue 45 stack in the third cell, as each one rises into the active row. Green ants close the last green highlight cells along the wall, and blue ants close the rest of the blue monitor screen. Green and blue share the dirt path, so leave one beat between each wave. Do not tap the green 35 or red 45 in source row 4 yet.
Tap the green 35 stack in the first cell of source row 4, then the red 45 stack in the second cell, as each one rises into the active row. Green ants close the last green highlight cells, red ants close the last red accent-strip cells and the last red wall frame cells, and the late refill waves that rise into the empty white buffer pad (the small white, black, purple, and blue cleanup refills) finish the white star cells, the dark outline, the purple banner, and the last blue monitor cells. The streaming room silhouette is complete once the last matching cube lands and the level banner appears.

Common Mistakes to Avoid

Firing the three red 30 stacks in source row 1 before the green 13, white 27, black 33, and purple 10 active row waves have cleared the perimeter of the streaming room, which sends red ants across the wall frame that black still has to outline and stalls them on the still-empty wall frame cells, blocking the red 84 in source row 2 and the red 45 in source row 4 that need to close the wall and the red accent strip.
Tapping the purple 10 stack in the fourth cell of the active row while green and white ants are still walking the dirt path up to the green corner lights and the white star cells, which strands purple ants on the still-empty banner cells and blocks the late purple refills that need to close the lower banner stripe.
Letting the blue 38 in source row 2 rise into the active row before the white star cells in the monitor are mostly closed, which strands blue ants on the still-empty monitor screen cells and blocks the blue 35 plus the blue 45 in source row 3 that need to close the rest of the monitor.

Lead with the green 13 stack in the first cell of the 5-cell active row, then the white 27 stack in the second cell, then the black 33 stack in the third cell, then the purple 10 stack in the fourth cell. This dispatches the green, white, black, and purple ants up the dirt path in that order and closes the green corner lights, the white star cells, the dark monitor outline, and the purple banner together before the three red 30 stacks in source row 1 are allowed onto the dirt path. Tap the three red 30s in source row 1 only after the four active row waves have cleared, and tap the black 45, red 84, blue 38, green 25, blue 35, blue 45, green 35, and red 45 source stacks only after the matching active row wave has cleared.
Why should I hold the three red 30 stacks in Colony Flow Level 45?
The three red 30 stacks in source row 1 use the same dirt path as the green 13, white 27, black 33, and purple 10 active row waves, and the red wall frame around the monitor only sits in cells that are still open while the green corner lights, the white star cells, the dark monitor outline, and the purple banner are still closing.
