How should I open Colony Flow Level 19?

Open with the 7 white stack in the leftmost cell of the 5-cell top row, then the 20 black stack in the second row of the main grid, then the 9 black refill in the buffer row, then the 10 yellow and 8 yellow stacks for the beak, then the 15 red and 20 red stacks for the round body. This closes the small white belly and the dark eye mask and tail before the wide red body and the refill waves (12 red, 14 white, 17 red, 13 red, 18 red, 6 red, 12 red, 5 red, 15 red, 10 white, 1 red) start climbing up from the main grid.

What breaks when the 20 red stack goes early in Colony Flow Level 19?

The 20 red stack fills the lower body and the dark tail edge, and red ants use the same dirt path as the white and black ants. If the 20 red is tapped before the round body is at least half-done, the red ants stall on the still-empty body cells, the dark eye mask and the yellow beak can no longer reach their cells, and the small 10 white and 1 red refill waves cannot find a clean staging space in the two white buffer slots.

Colony Flow! Level 19 Walkthrough

easy 4 colors

Colony Flow Level 19 is a round red bird pixel-art board where a small white belly, a short yellow beak, a dark black eye mask and tail, and a wide red body all use the same dirt path between two ant holes.

Board Notes

Layout: The board opens in portrait view. The top of the screen holds a pixel-art round red bird (Angry Bird silhouette): a wide red body, a small white belly, a black eye mask with a single dark eye cell, a short yellow beak on the front of the head, a dark black tail pointing back, and a small dark crest on top of the head, all framed by a thin dark outline. Two small dark ant holes sit on a dirt path directly below the pixel art, with a 2x speed toggle pinned in the upper-right corner. The working area below the path is a 5-cell top row followed by a 3-cell-wide 3-row main grid and a booster row at the very bottom. The top row opens as 7 white, 10 yellow, 8 yellow, and two empty white buffer slots on the right. The first row of the main grid shows 15 red, 15 red, 15 red. The second row shows 20 black, 15 red, and a 15 white tile. The third row shows 20 red, 15 red, and a 15 white tile.
Goal: Red cubes from the 15 red, 20 red, and the rising red refill waves must fill the wide round body, the crest on top of the head, and the dark tail. White cubes from the 7 white and the two 15 white tiles must fill the small white belly cell. Yellow cubes from the 10 yellow and 8 yellow stacks must fill the short yellow beak. Black cubes from the 20 black stack must fill the eye mask and the dark outline of the crest and tail.
Opening: The first confirmed tap is the 7 white stack in the leftmost cell of the 5-cell top row. White ants walk the dirt path up to the small white belly cell of the red bird and start filling it. The second tap is the 20 black stack in the second row of the main grid, which sends black ants up the right side of the path to begin drawing the dark eye mask and the dark tail. The third tap is the 10 yellow stack in the second cell of the top row, which starts filling the short yellow beak. The 8 yellow follows next, then the 15 red stacks in the first row of the main grid are tapped one at a time to start drawing the wide round body. The two empty white buffer slots in the top row stay open so refill waves (12 red, 14 white, 9 black, 17 red, 13 red, 18 red) can land in order as the top stacks are consumed.
Danger Zone: The danger zone is the two empty white buffer slots in the 5-cell top row. The video shows a long sequence of refill waves rising into those slots in order (12 red, 14 white, 9 black, 17 red, 13 red, 18 red, 6 red, 12 red, 5 red, 15 red, 10 white, 1 red), and parking the wrong color in either slot strands the next refill wave before it can rise into the active row. The other trap is tapping the 8 yellow stack in the top row before the 10 yellow has been sent, because the 8 yellow is the smaller half of the beak and the 10 yellow has to land first to open the beak cells cleanly. Tapping the 20 red in the third row of the main grid before the round red body is at least half-drawn is also bad, because red ants use the same dirt path as the white and black ants and a premature red click stalls the route on the still-empty body cells.
Mechanics: Level 19 is a multi-stack color-routing board with a single-color opener (the 7 white stack) and a pixel-art completion goal. The round red bird silhouette has to be filled from the small white belly and short yellow beak outward to the wide red body and the dark eye mask and tail. The 5-cell top row with two white buffer slots is the active queue, and the 3-cell-wide 3-row main grid underneath acts as the supply that refills the active row as stacks are sent. Compared with Level 16, this board has four visible colors (white, yellow, red, black), a 3x3 main grid plus a 5-cell top row, and a single-color opener (the 7 white stack) that closes a tight inner region while the larger red, yellow, and black stacks handle the wider body and outline. The two ant holes split the perimeter traffic, so the player can run a white or yellow wave on the left side and a black or red wave on the right side at the same time, but only if the two white buffer slots stay open. The win cue is the completed red bird art, not the play area going empty, so the last 1 red cubes still need a clean delivery after the bottom of the grid looks clear.

Quick Tips for Colony Flow! Level 19 (spoiler-free)

Tap the 7 white stack first to close the small white belly cell. The belly is the smallest colored region in the art and 7 white cubes are enough to finish it in a single wave before any larger white stack from the main grid arrives.
Send the 10 yellow stack before the 8 yellow stack. The 10 yellow is the larger half of the beak and has to land first to open the beak cells cleanly, otherwise the 8 yellow stalls on the still-empty beak region.
Keep the two empty white buffer slots in the 5-cell top row open. They are the only staging space for the 12 red, 14 white, 9 black, 17 red, 13 red, 18 red, 6 red, 12 red, 5 red, 15 red, 10 white, and 1 red refill waves that climb up from the main grid during the run, and parking the wrong color in either slot strands the next refill wave before it can rise into the active row.

How to Solve Colony Flow! Level 19 — Full Solution

Tap the 7 white stack in the leftmost cell of the 5-cell top row. White ants walk the dirt path up to the small white belly cell of the red bird and start filling it. Wait for the first white ants to clear the path between the ant holes before tapping the next stack.
Tap the 20 black stack in the second row of the main grid to start drawing the dark eye mask and the dark tail of the red bird. Black ants walk the right side of the path and start filling the dark cells of the head and tail. As the 20 black drains, a 9 black refill rises into the buffer row.
Tap the 10 yellow stack in the second cell of the top row, then the 8 yellow stack in the third cell. Yellow ants walk up to the short yellow beak and start filling those cells. The 10 yellow has to land before the 8 yellow, otherwise the 8 yellow stalls on the still-empty beak region.
Tap the 15 red stacks in the first row of the main grid one at a time, letting each red ant wave clear the path before the next. The round body is the widest single region of the red bird and needs all three 15 red stacks plus the 20 red to close. A 12 red refill rises into the buffer row during this beat.
Tap the 20 red stack in the third row of the main grid once the round body is at least half-done. Red ants walk the same dirt path and start filling the lower body and the tail edge. The 12 red refill in the buffer row is tapped next to keep the body closing.
Tap the rising red refill waves (17 red, 13 red, 18 red, 6 red, 12 red, 5 red, 15 red) one at a time as they land in the buffer row, letting each red ant wave clear the path before the next. The body closes progressively and the dark outline cells on the head and tail finish.
Finish by tapping the small 10 white and 1 red refill waves that land last, then any leftover 15 red or 15 white tile, to close the last dark tail cells and the very last body cells. The red bird silhouette is now complete and the level clears as soon as the last cube is delivered into its matching cell.

Common Mistakes to Avoid

Filling one of the two empty white buffer slots in the 5-cell top row with a red or yellow click, which strands the next refill wave (12 red, 14 white, 9 black, 17 red, 13 red, 18 red, 6 red, 12 red, 5 red, 15 red, 10 white, 1 red) before it can rise into the active row.
Tapping the 8 yellow stack in the top row before the 10 yellow has been sent, which sends the smaller half of the beak color into a region the 10 yellow has not yet opened and stalls the beak.
Tapping the 20 red stack in the third row of the main grid before the round red body is at least half-drawn, which sends red ants up the same dirt path as the white and black ants and stalls the route on the still-empty body cells.

Frequently Asked Questions

How should I open Colony Flow Level 19?
Open with the 7 white stack in the leftmost cell of the 5-cell top row, then the 20 black stack in the second row of the main grid, then the 9 black refill in the buffer row, then the 10 yellow and 8 yellow stacks for the beak, then the 15 red and 20 red stacks for the round body. This closes the small white belly and the dark eye mask and tail before the wide red body and the refill waves (12 red, 14 white, 17 red, 13 red, 18 red, 6 red, 12 red, 5 red, 15 red, 10 white, 1 red) start climbing up from the main grid.
What breaks when the 20 red stack goes early in Colony Flow Level 19?
The 20 red stack fills the lower body and the dark tail edge, and red ants use the same dirt path as the white and black ants. If the 20 red is tapped before the round body is at least half-done, the red ants stall on the still-empty body cells, the dark eye mask and the yellow beak can no longer reach their cells, and the small 10 white and 1 red refill waves cannot find a clean staging space in the two white buffer slots.
