How to beat Colony Flow! Level 423 — full solution

  1. Tap the Green 29 and Brown 34 boxes in the front row. They clear the outer green canopy and lower brown base, exposing inner layers.
  2. Tap the Yellow 16 box on the left and the Light Blue 30 box on the right. Yellow clears the top banana section while Light Blue strips the upper background sky.
  3. Tap the Brown 35 box from the middle row once revealed. It clears monkey body blocks along the right flank and chest.
  4. Tap the linked Light Blue 35 and Dark Green 30 pair once accessible in the middle row. Both slide into slots together, stripping remaining teal backdrop tiles.
  5. Tap the Dark Purple 40 box once freed. It clears the dark border and outlines surrounding the monkey.
  6. Tap the Red 35 box and the Beige 35 box as they reach the front row. They collect the red facial accents and outer beige fur.
  7. Tap the Yellow key and Pink key as their embedded blocks clear from the canvas. This unlocks the padlock boxes at the base of the stack.
  8. Tap the revealed Black 40 box and Beige 32 box. They clear monkey facial shading and inner fur blocks.
  9. Tap the Brown 18 box, Light Green 18 box, and remaining Yellow/Beige boxes to clear the final banana pieces and clear the board.

Moves that cost you the level

  • Tapping the linked Light Blue 35 and Dark Green 30 pair with fewer than two empty slots → one box is blocked and you jam the bay buffer.
  • Tapping the Yellow 16 box before Green and Brown clear its outer path → yellow blocks stay buried inside the monkey's banana, stalling the slot.

Quick tips for Level 423

  • Always preserve at least two open slots when a linked pair approaches the front row of the stack.
  • Strip picture layers strictly from outside to inside; keys embedded in the portrait cannot be reached until outer borders disappear.
Board breakdown5 notes
Layout
A pixel portrait of a monkey holding a banana sits above five slots and a multi-row stack containing linked boxes and padlock keys.
Goal
Clear all pixel blocks in the monkey portrait by matching them with ant boxes from the stack.
Opening
Begin with the Green 29 and Brown 34 boxes already in the front slots to peel away the picture perimeter.
Trap
Releasing interior Beige or Yellow boxes too early stalls slots because the central monkey face and banana are shielded by dark outlines.
Mechanic
Linked boxes must enter slots as a connected unit of two, requiring two open slots simultaneously.
