Colony Flow! Level 1667 Routing Order and Clearing Guide

To beat Level 1667 in Colony Flow!, clear the unobstructed outer perimeter tracks before tapping any pieces in the central grid. Releasing outer runners first opens turnaround space along the edges and prevents irreversible traffic jams in the center intersection.

Step-by-Step Clearing Sequence

Level 1667 features an interlocking board where mid-board paths cross a congested central hub. Peeling back the board from the exterior inward ensures your units have open exit corridors.

Phase	Board Location	Core Action	Failure Point to Avoid
1. Outer Flanks	Top-right and bottom-left borders	Drain direct perimeter lines immediately into exits	Launching paths that feed into central crossings
2. Corner Loops	Adjacent corner turnarounds	Route corner units into the newly vacated outer tracks	Leaving trailing segments across shared bends
3. Feeder Lanes	Outward-facing mid-board paths	Direct intermediate units into open edge corridors	Intersecting active streams that are still moving
4. Core Lockup	Center intersection cluster	Dispatch trapped center units through cleared lanes	Tapping units whose target exits remain blocked

1. Clear the Exterior Flanks

Begin by identifying the border paths on the top-right and bottom-left edges. These tracks do not cross the interior web and can drain directly into their exits. Releasing them immediately removes board clutter and creates essential clearance buffers.

2. Free the Corner Loops

Once the exterior tracks are empty, tap the units resting on corner turnaround tiles. Because the adjacent outer lanes are now open, these corner units can navigate the turns without causing pileups.

3. Route Mid-Board Feeder Lanes

Target the mid-depth lines that face toward the opened outer borders. Release these units one line at a time into the perimeter lanes. Do not tap a new lane until the preceding unit has fully exited the board.

4. Empty the Center Core

With the perimeter and intermediate lanes clear, the central intersection will have direct lines to the stage boundaries. Route the deepest trapped units out along the newly opened corridors to finish the level.

Preventing Common Deadlocks

Most failed attempts on Level 1667 occur from input timing mistakes and premature routing:

Do not tap the center early: Tapping congested interior units before their exit paths are cleared strands them across transit nodes, permanently blocking intersecting lanes.
Wait for full exits: Releasing an adjacent line while another is mid-transit causes tail collisions on shared corners. Allow each stream to completely leave the board before tapping the next piece.
Stagger shared funnels: When two lanes feed into the same exit, tap the forward unit closest to the funnel first. Only tap the rearward unit once the merge point tile is entirely empty.
