Colony Flow! Level 1970 Guide: How to Clear the Hard Puzzle

To clear Level 1970 in Colony Flow!, sort the colorful cubes along the perimeter into matching holes before moving items into the crowded central grid. This hard-rated stage features narrow pathways and tight worker ant movement, making it easy to overflow your limited colony slots if you move central cubes too early. Keeping your open board space free gives worker ants the necessary room to maneuver without triggering a deadlock.

Perimeter Management and Outer Space

Starting from the outer edges of the board creates an open buffer for subsequent moves. When beginning Level 1970, locate the cube colors positioned nearest to the exterior borders and direct your worker ants to drop them into their corresponding perimeter holes first.

Clearing the edges early provides two main benefits:

• Frees Up Moving Room: Open outer tiles allow worker ants to reroute around inner obstacles.
• Prevents Early Slot Congestion: Clearing immediate outer matches reduces the number of loose cubes held in active colony slots.

Avoid interacting with central cube clusters during your opening turns. Moving central pieces early blocks perimeter lanes and forces worker ants into long, inefficient detour routes.

Managing the Central Grid

The center of Level 1970 contains the highest density of matching holes and obstacles. Once the outer edges are stable, focus on long-distance moves that span across the board. Transferring cubes between distant points early prevents remaining routes from getting cut off later in the stage.

Keep these placement guidelines in mind when handling inner grid tiles:

• Route Long-Distance Cubes First: Prioritize cube pairs separated by large distances while key travel corridors remain open.
• Preserve Emergency Colony Slots: Keep at least two colony slots empty at all times to handle temporary cube storage during complex maneuvers.
• Delay Neighboring Matches: Do not automatically sort adjacent central cubes if doing so creates a wall that blocks worker ants from reaching isolated board sections.

Step-by-Step Order of Operations

Follow this structured sequence to maintain open paths and clear Level 1970 consistently:

1. Perimeter Clear: Direct worker ants to sort outer edge cubes into their matching holes to establish working room.
2. Long-Range Sorting: Transfer distant cubes across the central lanes while main corridors are still clear.
3. Internal Consolidation: Clear remaining short-range matches in the middle grid using the space freed up from the outer edges.
4. Final Verification: Scan open colony slots and remaining holes to ensure your final moves do not leave worker ants stranded without open paths.
