Colony Flow! Level 2670 Walkthrough and Clearing Strategy

To beat Level 2670 in Colony Flow!, clear the unobstructed outer perimeter lanes before moving any pieces in the tangled central cluster. Dispatching perimeter units directly into their matching exit docks preserves empty holding slots and creates the escape routes necessary to dismantle inward-facing blockades.

Recommended Clearing Sequence

Level 2670 features tightly packed, inward-facing paths where premature taps quickly fill staging slots and cause complete gridlock. Work from the outside edges inward using a four-phase order.

Phase	Target Area	Primary Action	Board Impact
Phase 1	Outer Flanks	Send single, unobstructed units straight to matching docks	Opens border lanes without consuming buffer slots
Phase 2	Secondary Ring	Tap units that only had a single outer blocker	Unlocks turn corridors for the interior rows
Phase 3	Central Core	Move the central linchpin unit once its exit path opens	Removes multi-directional deadlocks at the board center
Phase 4	Stragglers	Route remaining isolated units across open intersections	Clears the stage without needing extra holding slots

Managing the Holding Buffer

Limited buffer slots act as a temporary cushion for out-of-sequence moves, but filling them with mismatched colors will immediately fail the level.

Limit buffer usage to two units: Never allow more than two units to sit in the holding docks at once unless the next tap immediately completes a match or frees an exit.
Match buffered colors to incoming streams: If an interior piece must enter the buffer to unlock a pathway, pick a color that matches units currently nearing their exit so the slot clears right away.
Pause on three distinct colors: If three different colors occupy the staging area without immediate clear paths, stop tapping and re-evaluate path dependencies before making another move.

Untangling the Center and Avoiding Final Collisions

The middle rows contain opposing units facing each other along shared corridors. Successfully clearing the interior requires isolating the linchpin piece.

Locate the central linchpin: Find the single inward-facing unit that blocks two or more adjacent directional paths.
Clear the prerequisite blocker: Move only the specific secondary unit that directly obstructs the linchpin's escape line, routing it into a holding slot only if no direct path exists.
Discharge the linchpin: Send the linchpin through the newly opened lane immediately, freeing the surrounding rows.
Allow transit animations to finish: Wait for moving units to reach their destination before tapping trailing pieces at cross-sections to avoid path collisions.
Clear closest to exit first: When two remaining units share an intersection toward the end of the puzzle, always dispatch the unit closest to the gate first.
