Colony Flow Level 646 Walkthrough
A large orange shrimp sits above the word SHRIMP; open cyan 33, commit the cyan 30 -> black 20 -> white 26 link, and protect pad five while the mystery patch reveals.

How to Solve Colony Flow! Level 646 — Full Solution
- Activate cyan 33 and let the first water cubes drain from the leftmost pad.
- Start the cyan 30 -> black 20 -> white 26 link, preserving the fifth tray position while its three colors route.
- Add cyan 35, then red 30 and orange 30 as the water, shell, and body lanes become available.
- Cycle cyan 34/35 and orange 26/30 separately; wait whenever linked white or black still holds a pad.
- Route red 24 and the late black 20 outline after the gray mystery patch reveals the shrimp's left-side colors.
- Clear the last cyan, orange, red, black, and white remnants and wait until the SHRIMP lettering and all five pads empty.
Colors in this level:
Cyan, Orange, Red, Black, White, Yellow
Common Mistakes to Avoid
- Treating the three-stack link like one tray position leaves no landing space for the next shell color.
- Starting red 24 before its hidden band appears holds a pad without removing visible cubes.
- Running two long cyan groups together delays the compact orange and black cleanup.
Quick Tips for Colony Flow! Level 646 (quick clues)
- Count the opener link as three pads.
- Run one cyan background group at a time.
- Delay red 24 until its shell band is exposed.
- Wait for the mystery patch before the final outline cleanup.
Board notes 5 details
- Layout
- Orange shrimp with red shell bands, dark outline, cyan water, white bubbles, and SHRIMP lettering. The five-pad tray faces cyan 33, a cyan 30 -> black 20 -> white 26 link, orange 30, red 30/24, cyan 35/34/30 groups, orange 26/30 groups, and a gray mystery patch.
- Goal
- Drain the cyan water and lettering, expose the mystery patch, then clear the orange body, red shell stripes, white highlights, and black outline.
- Opening
- Start cyan 33, then activate the linked cyan 30, black 20, and white 26 stacks; add cyan 35 only after one linked color begins draining.
- Danger Zone
- The three-color link consumes three tray positions, so adding red 30 and another cyan group too early can occupy all five pads.
- Mechanics
- Written pixel art, a hidden shrimp-side patch, and a three-stack cyan-black-white link force alternating background and body batches.
Frequently Asked Questions
What opens Level 646?
Start cyan 33, then commit the cyan 30 -> black 20 -> white 26 linked group.
Why must the fifth pad stay empty?
The linked opener already occupies three pads, and the spare position admits the first useful red or orange stack.
When should red 24 be used?
Wait until the gray mystery patch exposes the remaining red shell band.
What proves the shrimp is solved?
The orange body, cyan water, and SHRIMP lettering vanish and all five pads return to white.
