Colony Flow Level 19 asks you to fill the entire grid by connecting matching colors while managing refill waves that rise from empty cells at the bottom.
The core challenge combines standard Flow puzzle-solving with Colony mechanics where strategic placement determines which cells trigger new blocks during play. This walkthrough focuses on the clearest path to a Full solution: which color pairs to connect first, how to position your lines to control refill timing, and where to leave temporary gaps so rising waves don’t block your final connections.
The goal is a complete grid with all colors properly linked and no dead spaces remaining.
Colony Flow Level 19 Walkthrough
Colony Flow Level 19 presents a round red bird in pixel art, divided into White, Yellow, Red, and Black regions. All ant colors share a single dirt path between two ant holes. The five-cell top row holds the initial stacks and serves as a staging area for refills that rise from the main grid below. Clear the small regions first—White belly, Yellow beak, Black eye mask—then work through the Red body waves one at a time. Keep the two rightmost top-row slots empty so refills can rise in sequence. Overlapping Red waves will block the shared route.
Full Solution
- Tap the 7 White stack in the leftmost top-row cell. White ants walk up to clear the small White belly.
- Tap the 20 Black stack in the second main-grid row. Black ants clear the eye mask and dark tail. A 9 Black refill rises into the buffer row.
- Tap the 10 Yellow stack, then the 8 Yellow stack. The 10 Yellow must land first to open the beak cells cleanly. Reversing the order stalls the 8 Yellow wave.
- Tap the three 15 Red stacks in the first main-grid row one at a time. Let each Red wave drain before tapping the next.
- Once the Red body is at least half-cleared, tap the 20 Red stack in the third main-grid row, followed by the 12 Red refill that rises into the buffer row.
- Tap the rising Red refills in order: 17, 13, 18, 6, 12, 5, and 15 Red. Wait for each wave to clear the path before sending the next.
- Finish with the 10 White, 1 Red, and any remaining 15-value stack. The board clears when the last cube reaches its matching cell.
Quick Tips
- Keep the two rightmost top-row slots open. Refills rise into these buffer spaces in a fixed sequence: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.
- Always send 10 Yellow before 8 Yellow. The 10 Yellow opens the beak route; the 8 Yellow finishes it.
- Let each Red wave drain before tapping the next. Overlapping Red ants block the shared path.
- White clears the belly, Yellow clears the beak, Black handles the eye mask and tail outline, and Red fills the body, crest, and tail edge.
Key Challenges
The challenge in Level 19 is space and timing, not color matching. The top row begins with7 White, 10 Yellow, 8 Yellow, and two empty buffer cells. Those empty cells stage the refill waves that rise from the main grid during play. Filling either slot with the wrong color strands the next refill before it can rise into the active row.
The Red body is the largest region and requires most of the Red stacks. Clearing the small White, Yellow, and Black regions first prevents those colors from competing with the long Red sequence later in the level. Tapping the 20 Red stack in the third row before the body is at least half-cleared sends Red ants up the same path as White and Black ants, stalling the route on remaining body cells.
