Colony Flow Level 638 Walkthrough
A red-haired portrait opens with red 5, red 18, and a forced red 20 -> black 40 link; protect the fifth tray pad, rotate the tan, cyan, pink, and green layers, and let green 2 clear last.

How to Solve Colony Flow! Level 638 — Full Solution
- Activate red 5, red 18, and red 20, then allow the attached black 40 to enter the fourth tray position.
- Hold the fifth pad until red 5 or red 18 clears, then load red 25 instead of starting two new colors.
- Continue the remaining red hair and black outline before introducing tan 35 and the first cyan layer.
- Rotate cyan 46, tan, pink, and green through exposed portrait regions while reserving one pad for each link.
- Reduce the late green 24, tan 8, black 9, cyan 4, and pink 2 as one controlled mixed tail.
- Process red 20 and green 42 after the smaller cyan and pink fragments leave.
- Clear the last tan and black pieces, then drain green 2 to empty the portrait.
Colors in this level:
Red, Black, Green, Cream, Tan, Pink, Cyan
Common Mistakes to Avoid
- Using the fifth pad before a short red opener clears leaves no room for a link.
- Starting red 25 and tan 35 together crowds the forced black 40 route.
- Loading green 42 before the tiny cyan and pink fragments leave prolongs the mixed tail.
Quick Tips for Colony Flow! Level 638 (quick clues)
- Protect the fifth tray pad.
- Clear red 5 before tan 35.
- Follow the black 40 link immediately.
- Leave green 42 for the late board.
Board notes 5 details
- Layout
- Red-haired portrait with a green top, cream-and-tan face, pink cheeks, pale-cyan background, and charcoal outline. The reserve starts with red 5, red 18, red 20 linked to black 40, red 25, and tan 35.
- Goal
- Remove the red hair and linked black outline, then work through cyan, tan, pink, and green until the portrait is empty.
- Opening
- Start red 5, red 18, and red 20, accept its linked black 40 in the fourth pad, and hold the fifth pad until a short red group clears.
- Danger Zone
- The red 20 -> black 40 pair occupies two long-lived positions; adding red 25 and tan 35 together removes the only buffer for later links.
- Mechanics
- A compact four-position red-and-black opener leads into linked portrait layers and a green-dominant endgame without mystery stacks.

Are there mystery stacks?
No mystery stack is visible in the reviewed solve; the challenge comes from linked color layers.
What clears last?
The observed finish drains the final green 2 after the remaining tan and black pieces.
