Level 451 displays a pixel-art deer against a pale blue sky with a butterfly and flower. Clear the background sky and border blocks first to unlock internal brown and beige deer segments without clogging slots. Avoid trapping brown ant boxes before the deer body is uncovered.

How to beat Colony Flow! Level 451 — full solution

  1. Tap the White 40, Hot Pink 24, and Red 15 boxes in the front row of the stack. Ants clear the white borders, the red butterfly, and hot pink flower petals on the left edge.
  2. Tap the Light Blue 8 box from the front row left and Cyan 38 box once exposed. Ants carry away the light blue sky perimeter, peeling back the background to expose the deer silhouette.
  3. Tap the Brown 16 and Brown 38 boxes. Ants begin dismantling the upper-right ears, head outline, and outer flanks of the deer.
  4. Tap the Beige 10 box and Brown 35 box. Ants clear the lighter muzzle, chest spots, and inner facial contours.
  5. Tap the Brown 40 and Beige 38 boxes. Ants collect the central body mass and belly patches as interior blocks become accessible.
  6. Tap the locked Brown 40 and Beige 34 boxes once the green padlock unlocks. Ants remove the final deer back and leg blocks to finish the level.

Moves that cost you the level

  • Tapping the Brown 16 or Brown 38 box before clearing the White 40 and Light Blue 8 sky blocks → brown blocks inside the deer body remain buried, causing brown boxes to jam all available slots.
  • Filling all five slots before uncovering the green key → the locked Brown 40 box cannot open and ant progress halts completely.

Quick tips for Level 451

  • Prioritize peeling off outer background colours like Light Blue and White so inner animal colours become exposed from all sides.
  • Keep at least one slot empty while waiting for key blocks to dissolve and release locked boxes in the stack.
Board breakdown5 notes
Layout
A pixel portrait of a resting deer surrounded by a butterfly and flower against a light blue backdrop, with 5 slots positioned above a stacked queue of ant boxes.
Goal
Clear all pixel blocks on the board using ant boxes from the stack.
Opening
Deploy White 40, Hot Pink 24, and Red 15 from the front row to clear outer perimeter details and reveal lower rows.
Trap
Deploying the heavy Brown boxes early stalls the slots because most brown deer pixels are shielded behind sky and border blocks.
Mechanic
Padlocked boxes in the stack require collecting a matching key hidden in the pixel grid before they can be tapped.
