Colony Flow! Level 625 Walkthrough: Step-by-Step Solution

To beat Level 625 in Colony Flow!, clear the unobstructed outer perimeter paths first, then dispatch the remaining colors one by one through the shared central intersection only after each line has completely entered its matching nest. Rushing interior groups before the perimeter is clear causes ant collisions at crossing points, immediately jamming the board and failing the stage.

Level 625 Board Layout and Hazards

Level 625 features narrow perimeter channels wrapping around a tightly congested core. Multiple colored ant streams must maneuver toward their target drop-off nests, but two separate colors share a single central intersection.

The stage presents two major failure conditions:

• Junction Collisions: If two intersecting ant lines are triggered at the same time, their identical movement speeds cause them to collide at the crossing point.
• Premature Core Dispatch: Activating an interior cluster before its exit channel is empty leaves ants stranded in the path of incoming traffic, locking the entire grid.

Opening up the outer boundary provides the buffer space needed to see the remaining core paths clearly and avoids accidental crossover conflicts.

Routing Phases

Manage traffic across the board by clearing sections from the outside in. Never route two crossing paths simultaneously.

Step-by-Step Clearing Sequence

Follow this order to route all ant swarms into their matching nests without collisions:

1. Scan the Board Edges: Locate the colored nest that connects to an unobstructed channel running along the board frame. Tap and route this swarm along the wall, keeping it entirely outside the central junction.
2. Wait for the Lane to Empty: Allow every ant in the initial group to enter its nest before tapping any other color. The vacated path now serves as a secondary bypass channel.
3. Route the Secondary Flank: Send the adjacent flank swarm down the cleared outer boundary to bypass the center entirely.
4. Isolate the Center Cluster: With exterior traffic resolved, examine the two remaining colors in the core. Identify the color that has a direct, straight-line vector through the central crossing.
5. Send the Primary Core Group: Tap and route this interior color through the central intersection. Keep your hands off the screen while the line moves to prevent accidental inputs.
6. Finish with the Final Swarm: Confirm that the last ant of the previous swarm has crossed the junction threshold and entered the nest, then dispatch the final ant group through the middle.

Key Mistakes to Avoid

• Early Dispatch at Crossing Nodes: Tapping the next color while the preceding line still has trailing units crossing the junction causes an instant collision. Wait until the crossing node is completely vacant.
• Misjudging Nest Hitboxes: The colored drop-off holes on Level 625 sit close together. Trace your path visually before confirming the release to ensure the route does not graze an adjacent nest entrance.
• Tackling the Center First: Attempting to untangle the middle cluster before clearing the edges removes your outer buffer lanes and clutters the board, making collision-free navigation far more difficult. Clear the perimeter first to ensure a reliable run.
