Colony Flow! Level 587 Clearing Order and Route Guide

To beat Level 587 in Colony Flow!, clear the exterior perimeter ants before releasing any units from the congested center. Releasing unblocked ants along the edges opens up turning room and removes cross-traffic conflicts. Once edge units are cleared, you can route the interior ants through central intersections without triggering collisions or gridlock.

Priority Clearing Sequence

Level 587 packs multiple overlapping trails around a tight central junction. If you tap an interior ant while outer lanes remain occupied, it will collide with blocking units or permanently seal off necessary turning channels. Work systematically from the outside in using this sequence:

1. Locate Direct Outer Exits: Scan the borders for perimeter ants facing straight toward exit lanes without crossing any neighboring paths.
2. Send Out Corner Units: Corner pieces typically hold single-direction paths. Releasing these removes immediate border collisions and exposes turning angles for adjacent lanes.
3. Peel the Outer Ring: Dispatch remaining boundary ants row by row. Each departure widens clearance along the outer perimeter.
4. Hold the Center Stationary: Keep interior clusters untouched during the opening phase, even if a unit appears partially free, to prevent cutting off boundary traffic.

Resolving Central Junctions

Once the perimeter is clear, the remaining puzzle funnels into central chokepoints where perpendicular paths cross the same tiles.

To safely clear the middle:

• Identify the deep blocking unit: Determine which color trail sits directly across the intersection. Tapping the unit that physically occupies the junction tile clears the lane for cross-traffic behind it.
• Trace lines from tail to head: If a queued ant halts midway, find the specific crossing unit that obstructs its line and release that unit first.
• Wait out movement animations: Launching units too quickly causes mid-intersection collisions. Let a moving ant fully clear the crossing tile before triggering a perpendicular unit.

Common Deadlocks and Prevention

Because active flow paths cannot intersect simultaneously, tapping units out of order creates irreversible traffic jams.

Endgame Cleanup

After resolving the central junction, the remaining units sit in isolated, open corridors.

Finish the board by launching units one at a time along direct straightaways. Avoid tapping parallel lanes simultaneously; spacing your moves guarantees that trailing units do not clip crossing paths, allowing you to complete the stage cleanly.
