Colony Flow! Level 255 Walkthrough
Level 255 features a circular shield made of Cyan, Red, White, and Blue blocks, with a locked box requiring a Blue Key hidden in the outer ring. Carve directly through the lower rings to expose inner colours and retrieve the key safely. Avoid filling slots with Blue or White before a path reaches their inner layers.

How to beat Colony Flow! Level 255 — full solution
- Tap the three front Cyan boxes (Cyan 15, Cyan 20, Cyan 15) into the first three slots. The Cyan ants carry off the outer perimeter and bottom border, exposing the lower edge of the outer Red ring.
- Tap Red 20 (front row, left), Blue 10 (front row, middle), and White 20 (front row, right). The Red ants carve a wide breach through the bottom Red ring, immediately exposing the middle White ring and inner Blue circle so the accompanying White and Blue ants can begin carrying blocks.
- As the initial boxes deplete, tap the revealed White 20 (front row, left), Blue 26 (front row, right), and an incoming Red 14. The ants bore directly through the lower halves of all concentric rings, uncovering the central White star and pushing toward the Blue Key on the left.
- Continue tapping incoming White and Blue boxes alongside Red 15 to clear through the core. The Red ants on the left reach and collect the embedded Blue Key, while the inner White star and Blue circular background are cleared out.
- With the Blue Key collected, the locked box in the stack unlocks. Tap the unlocked box together with White 1 and Blue 12/13 into the open slots, stripping away the upper White ring and top Blue core blocks to leave only the upper Red arch and outer Cyan corners.
- Tap the remaining Cyan 15, Cyan 20, and the final Red boxes into the slots. The ants clear away the topmost Red arc and remaining outer Cyan corner blocks to finish the level.

Moves that cost you the level
- Tapping Blue 10 and White 20 before the bottom Red ring is breached → neither Blue nor White blocks are exposed at the start, jamming two slots indefinitely.
- Filling all five slots before collecting the Blue Key → the locked box in the stack remains blocked and slot gridlock prevents clearing newly uncovered layers.
Quick tips for Level 255
- Tunnel upward through concentric rings from the bottom nest to expose inner White and Blue layers as early as possible.
- Prioritize clearing the left portion of the outer Red ring to release the Blue Key before running out of accessible boxes in the stack.
Board breakdown5 notes
- Layout
- The picture is a circular shield surrounded by Cyan background blocks, with an ant nest centered directly below. Five slots sit above a three-column stack of ant boxes.
- Goal
- Clear all Cyan, Red, White, and Blue blocks from the shield picture using ant boxes. No timer is present.
- Opening
- Deploy the three front Cyan boxes (Cyan 15, Cyan 20, Cyan 15) to strip the bottom Cyan border, then follow with Red 20 to breach the shield's outer ring.
- Trap
- Tapping inner-layer boxes like Blue or White before Red has breached the shield perimeter leaves those boxes stranded in slots with no exposed blocks to carry.
- Mechanic
- A locked box in the stack requires a Blue Key embedded inside the left side of the outer Red ring. Removing the adjacent Red blocks frees the key to unlock the box.

How do I unlock the locked box in Colony Flow! Level 255?
Direct Red ants to clear the left side of the outer Red ring. This frees the embedded Blue Key, which automatically travels down to unlock the box in the stack.
