Colony Flow Level 20 Walkthrough guides you through solving a puzzle where the empty white buffer serves as the only staging cell available at the start.
This level requires careful sequencing to move colored flows through the limited workspace without blocking your own progress. This article focuses on the clearest play-focused answers and practical mechanics you need to complete the level.
You’ll find specific move sequences, staging strategies for the white buffer cell, and how to route each flow to its matching colony without creating deadlocks.
Colony Flow Level 20 Walkthrough
Colony Flow Level 20 presents a strawberry-cake pixel-art board where yellow, pink, red, green, brown, black, and purple ants share one dirt path. The critical detail: preserve the empty white buffer slot at the top-right corner for the brown refill. Filling that slot early with pink 17 or green 8 strands the brown dish ants and leaves a visible gap.
Full solve order:
- Tap yellow 36 (far-right cell, second row). Yellow ants clear the wide cake filling. Wait one beat for the wave to reach the cake’s bottom edge.
- Tap yellow 30 (top row, second from left). The second yellow wave continues clearing the filling while the first wave finishes the perimeter.
- Tap pink 32 (left cell, third row). Pink ants begin clearing the strawberry body. Do not tap pink 30 or pink 17 yet.
- Tap the brown refill immediately when it rises into the top-right white buffer slot. Brown ants clear the dish beneath the strawberry. If pink 17 or green 8 occupies this slot first, the brown refill is stranded.
- Tap pink 30, pink 17, pink 12 in sequence. Let each pink wave clear its section before dispatching the next.
- Tap red 28, then the two red 30 stacks. Leave a short gap between red waves—red and pink share the path.
- Tap green 8, then green 20 once most of the strawberry body is clear. Green ants finish the leaf and stem.
- Clear remaining stacks: black 25, purple 10, red 20, pink 35, plus any late refills until the board is empty.
Gameplay Mechanics
Tap numbered cube stacks to send ant carriers along the dirt path. Each wave delivers cubes to matching color regions in the strawberry-cake image. Yellow, pink, and red compete for the main perimeter route, so yellow must be mostly drained before sending larger pink and red waves.
The brown dish is the board’s timing check: its refill requires the top-right staging space, and blocking that slot prevents dish completion.
Quick Tips
- Start with yellow 36. The wide cake filling creates working room for later waves.
- Reserve the top-right buffer for brown. Do not use it early with pink 17 or green 8.
- Drain yellow before committing to pink and red. Early pink or red waves stall against unfinished yellow cells and crowd the route.
- Send one wave at a time. Brief gaps between stacks let ants clear the perimeter and avoid path congestion.
- Save green until late. The leaf and stem clear more reliably after most of the strawberry body is finished.
Board Layout and Challenges
The board is a four-row, four-column grid with one extra white buffer slot at the top-right. The 4×4 grid reads, top to bottom and left to right: pink 12 / yellow 30 / pink 17 / green 8 in row one; red 28 / black 25 / yellow 36 in row two; pink 32 / pink 30 / purple 10 / red 30 in row three; red 30 / red 20 / pink 35 / green 20 in row four.
Main challenges:
- Shared ant path: Yellow, pink, and red use the same route. Dispatching too many later stacks before yellow is drained causes stalls.
- Buffer management: The top-right white slot is the required staging space for the brown refill.
- Refill timing: Watch for late stacks after the main board appears nearly clear, especially brown and final color waves.
- Completion requirement: Clear every color region and refill stack to finish the strawberry-cake image and unlock Level 21.
Common Mistakes
- Filling the top-right buffer with pink 17 or green 8 before the brown refill rises, which strands the brown refill and leaves a visible gap under the strawberry.
- Tapping pink 12 or pink 17 before yellow filling is at least half-cleared, which strands pink ants on remaining cake cells and blocks the brown refill.
- Tapping green 8 too early, which sends green ants across unfinished strawberry body cells and stalls them on the stem.

How Is This Level Different?
Level 20 combines seven color targets in one layered strawberry-cake design: yellow cake filling, pink strawberry body, darker red dot cells, green leaf and stem, brown dish, black outline, and purple accent. Clearing these regions gradually reveals the completed image. Nearby levels in the Colony Flow progression use the same ant-delivery mechanics, but stack layouts, refill timing, and staging spaces change from board to board.
