Colony Flow! Level 587: How to Clear Central & Perimeter Blocks

To clear Level 587 in Colony Flow!, dismantle the high-density block clusters in the center of the board first. Clearing the central grid creates horizontal movement lanes, which allows you to move blocks from the top and bottom without trapping outer pieces in dead zones.

Clear Central Bottlenecks First

The middle of the grid in Level 587 acts as a bottleneck. Leaving these blocks untouched restricts movement across the rest of the board and prevents pieces on the edges from connecting.

Target Horizontal Lanes: Focus on removing blocks that span horizontally across middle rows. Opening these lanes establishes main pathways to move blocks from the top and bottom halves of the grid.
Create Working Space: Dismantling the central group first provides the open space needed to maneuver larger block clusters later in the puzzle.

Clear Outer Edges and Corner Blocks

Once central lanes are open, clear the perimeter to prevent pieces from becoming permanently trapped. Corner blocks are the main failure point in Level 587 because they easily form unreachable isolated tiles.

Check Outer Rows and Columns: Find the outermost edge with at least two connected blocks.
Clear Corner Connections: Remove pieces adjacent to corners as soon as a path opens. Leaving corner spaces occupied blocks peripheral flow lines.
Work Inward: Move step-by-step from the outer edges toward the center to avoid leaving disconnected single blocks.

Execution Strategy and Pitfalls to Avoid

Maintaining movement options is critical to completing the level before running out of valid moves or board space.

Priority	Strategy	Goal
1. Center Axis	Remove high-density middle clusters	Establish horizontal flow lanes across the board.
2. Corners	Clear corner-adjacent connections immediately	Prevent dead zones and trapped edge pieces.
3. Full Paths	Target trigger blocks that collapse entire lines	Minimize total moves and preserve free space.

To avoid gridlock, check the surrounding tiles before executing a move. Avoid creating isolated single blocks ("islands") that have no direct connection to nearby paths, as clearing them later requires extra moves. If a section becomes crowded, clear an adjacent edge piece to open a new entry path into the center.
