Colony Flow! Level 700 Strategy Guide

To clear Level 700 in Colony Flow!, resolve the color nodes along the outer edges of the board before connecting central paths. Securing the perimeter first preserves open space in the middle, preventing gridlock in this high-density stage.

Grid Layout and Constraints

Level 700 features a tight board with non-symmetrical node layouts and fixed obstacles that restrict worker movement and cube routing.

Dead Zones: Designated spaces on the grid prohibit connections. Routing lines through these areas blocks access to adjacent targets.
Central Bottlenecks: Narrow gaps between obstacles limit the number of paths that can cross the center simultaneously.
Limited Colony Slots: Indiscriminate move choices fill available pathways quickly, cutting off access to exit terminals.

Step-by-Step Pathing Strategy

Clearing Level 700 requires establishing perimeter paths to keep central lanes clear for awkward color pairs.

Identify Outer Pairs: Locate the color pairs closest to the board boundaries before making any moves.
Form Edge Lines: Draw shortest-path connections along the outermost available tiles, hugging wall boundaries to conserve grid space.
Snake Outer Routing: If a direct perimeter line is blocked, curve the line along vacant outer tiles rather than cutting inward.
Target Distant Nodes: Connect awkward or widely separated pairs early so they do not get isolated by easier connections.
Fill Central Lanes: Use remaining central gaps to finish short, direct connections once the perimeter is stabilized.

Priority Level	Route Type	Target Location	Goal
High	Outer Perimeter	Board boundaries	Prevents early grid congestion
Medium	Awkward / Distant	Across outer tiles	Avoids isolating difficult nodes late in the run
Low	Short / Central	Inner grid gaps	Completes remaining paths without extra turns

Troubleshooting Dead Ends

If the board locks and no valid moves remain, your line order likely trapped an unresolved color pair.

Check for Isolated Nodes: Inspect whether an outer path completely cuts off access to a target node. If so, clear the blocking line and route it one tile closer to the edge.
Reduce Unnecessary Turns: Every extra turn consumes grid space. Keep lines straight wherever possible to avoid creating kinks that restrict adjacent slots.
Reverse Connection Order: If completing edge nodes first still causes a bottleneck, connect the most distant awkward pair first to establish your anchor route, then build outer lines around it.
