What must happen before the final cleanup?

The left 500 counter must be drained and the yellow key route must release the right-hand 20 lock.

Which stacks create the most pressure?

Dark green 67, cream 50, cyan 50, and cyan 47 are the long groups to separate.

Keep a pad open while the counter falls, then use yellow 20 and its key-linked route to open the lock.

The counter and lock disappear with the flame, trees, sky, ground, object, tray pads, and final small fragments.

Colony Flow! level guide

hard 8 colors

The hard Level 714 flame-and-boat scene lowers a 500 counter, opens a yellow 20 lock with its key lane, and then clears the sky, trees, and ground.

If the player asks you to sign in, open the video on YouTube instead.

Feed dark green 67 and the first cyan 30/30 groups, allowing the 500 counter to fall while the long routes complete.
Add red 40, yellow 20, and cream 50 only as a pad returns; keep the yellow key lane visible rather than burying it behind cyan 50.
Route the yellow key-linked group into the right-hand 20 lock and wait for the lock panel to release.
Alternate cyan 47/50/32/42 with green 30 and remaining dark-green foliage to clear the sky and the cyan/yellow right-side object.
Remove the red or maroon ground and yellow flame, then finish the small 2/5/13/23 fragments and wait for the counter, lock, tray, and board to clear.

Colors in this level:

Brown, Green, Lime green, Cyan, Charcoal, Red, Yellow, White

Starting cyan 47 and cyan 50 together can consume the five-pad buffer before the key route is ready.
Ignoring the 500 counter while chasing the flame delays the release of the rest of the scene.
Filling the last pad before yellow 20 is linked leaves no space for the lock-opening wave.

Board notes 5 details

Layout: Yellow flame or campfire at left, turquoise sky, green trees and bushes, dark maroon ground, and a cyan-and-yellow boat-like object at right. The opening board shows a left 500 counter and a yellow lock marked 20, with dark green 67, cyan 30/30, charcoal 25, red 40, yellow 20, cream 50, green 30, and cyan 47/50/32/42 reserves.
Goal: Lower the 500 counter, release the right-hand yellow 20 lock, and empty the sky, foliage, flame, maroon ground, and cyan/yellow object.
Opening: Use the exposed dark-green and cyan groups to make progress on 500 while preserving one pad for the yellow key lane; route yellow 20 and its linked groups when the key becomes visible.
Danger Zone: Dark green 67, cream 50, cyan 50, and cyan 47 are long runs that can fill all five pads before the counter or key-linked lock has finished.
Mechanics: Two visible gates control the scene: a 500 counter and a yellow 20 lock with a key route. Counter progress and the lock release must be paced before broad scene cleanup.

What must happen before the final cleanup?
The left 500 counter must be drained and the yellow key route must release the right-hand 20 lock.
Which stacks create the most pressure?
Dark green 67, cream 50, cyan 50, and cyan 47 are the long groups to separate.
When should the yellow lane be used?
Keep a pad open while the counter falls, then use yellow 20 and its key-linked route to open the lock.
What is the completion cue?
The counter and lock disappear with the flame, trees, sky, ground, object, tray pads, and final small fragments.
