How to Solve Colony Flow! Level 421 — Full Solution
- Tap dark purple 16, then green 15 and green 15; let both green routes return before adding another long stack.
- Tap dark purple 26 and white 31, keeping the first white buffer available while the brown gate enters its first release.
- Use white 40, green 28 and green 30 as their matching holes open, waiting after each long dispatch for the ants to clear the lower edge.
- Route dark purple 40 and dark purple 40 one at a time, then use dark purple 38 only after the cyan-lock side has a free lane.
- When the gate reaches the low 100s, clear green 1, green 24/20 and dark purple 9 before starting another dark 40.
- Feed white 7/13/30 and dark purple 8/34/35 while preserving the white slot for the short return that opens the lower belt.
- Continue with dark purple 3/7/33/37 and green 30/11 while the hood collapses to the face and torso fragments; wait through each perimeter jam.
- Finish white 1/9/11/26/28 and the last dark purple 21/35/40 route, then wait for every ant and the empty-board clear animation.
Colors in this level:
Dark purple, Green, White, Yellow, Cyan, Brown
Common Mistakes to Avoid
- Starting dark-purple 40/40 and white 40 together fills the buffer before the yellow and cyan key lanes are ready.
- Tapping dark purple 38 while ants still cover the cyan-lock side strands the lower route and delays the final clear.
Quick Tips for Colony Flow! Level 421 (spoiler-free)
- Use the short dark-purple 16 and green 15/15 opener before committing to the 40-cubes.
- Keep one white slot free through the dark-purple 40 wave and the cyan-lock transition.
- Wait for the lower perimeter ants to return before tapping the next dark 30-plus stack.
Board notes 5 details
- Layout
- A dark-purple hooded or dark-haired white-faced figure with green trim, yellow and cyan key-like accents, and a brown bottom gate. The visible opening queue is dark purple 16, green 15/15, dark purple 26, white 31, then white 40, dark-purple 40/40, green 30, white 40, green 28, dark purple 40 and dark purple 38.
- Goal
- Route the dark-purple, green and white cubes through their matching holes, open the yellow and cyan key lanes, drop the brown gate and remove the final face, hood and belt pixels until the board is empty.
- Opening
- Tap dark purple 16, green 15, green 15, dark purple 26 and white 31 in that order, waiting for the short green and dark ants to return before taking the next long route.
- Danger Zone
- The linked dark-purple 40/40 pair, white 40 and green 30 can fill every slot before the key lanes open. Keep one white buffer slot free and delay dark purple 38 until the cyan-lock side is clear.
- Mechanics
- A staged-gate, limited-buffer multi-stack board with heavy dark, green and white perimeter traffic and two late key releases.
Frequently Asked Questions
Why does dark purple 16 go first?
It is the short opener shown before the paired green 15 stacks and the dark-purple 26 route, so it starts the brown-gate release without consuming the long-route buffer.
When should I use the cyan-lock side?
Wait until the dark 40 traffic has returned and one white slot is empty; the cyan side is needed for the late belt and face fragments.
