To clear Level 450 in Colony Flow!, route the unobstructed outer perimeter paths first before touching the interior cluster. The board concentrates multiple entry points toward the center and places destinations along the edges, funneling several color groups through a tight two-column central corridor. Sending interior units early cuts off perimeter paths and causes permanent traffic locks.
Phased Clearance Order
Solve the board from the outside inward to preserve the center as an open junction.
| Phase | Target Area | Objective | Collision Risk |
|---|---|---|---|
| Phase 1 | Outer Flanks | Send units with direct, unobstructed wall paths home | Low; no shared interior intersections |
| Phase 2 | Secondary Ring | Divert intermediate ants along cleared perimeter tiles | Medium; watch intersecting turn corners |
| Phase 3 | Central Core | Route high-density center groups straight to their nests | High; premature entry deadlocks adjacent colors |
| Phase 4 | Remnants | Guide remaining isolated units into open nests | Low; wide transit lanes available |
Step-by-Step Path Execution
- Clear the Outer Flanks
Locate the ant group situated against the outer boundary that has a direct, turn-free route to its matching nest. Direct this group home immediately. This opens up border lanes that serve as bypass routes for more congested tiles.
- Route the Secondary Feeder Line
Select the intermediate group positioned next to the newly cleared edge. Guide these ants along the empty perimeter corridor rather than cutting across the central grid. Keeping the middle clear preserves the transit space required by locked interior units.
- Release the Central Cluster
With the outer bypass lines established, activate the heavily restricted central color group. These ants have limited flexibility and must travel straight across the middle columns. Because the central intersection is unobstructed, this cohort can reach its destination without blocking neighboring lines.
- Finish Trailing Remnants
Send the remaining isolated colors to their respective targets. With both the core and perimeter channels cleared, these ants have multiple unobstructed paths to finish the stage.
Common Mistakes and Failure Points
- Solving Inside-Out: Activating central paths first cuts across border corridors, permanently isolating exterior units from their destination holes.
- Tight Cornering: When routing around an obstacle, curving too close to unreleased spawn points can block subsequent units. Always swing paths wide along cleared outer borders.
- Overlapping Inputs: Triggering a new color line while a previous unit is actively walking across a shared intersection tile triggers an immediate collision failure. Wait for the transit animation to finish before initiating the next movement.

Good guide for Colony Flow! players. The updates part was useful.
Nice guide. I am checking the other Colony Flow! articles next.
This helped me understand updates much better.
