ROUTE field guide

ROUTE Grid Rules Explained in Plain Language

A compact rulebook for markers, targets, playable dots, defender cells, adjacency, and completion.

Markers have fixed jobs

Each receiver belongs to one target. Endpoint color and identity define the pair and cannot be swapped.

Defenders reshape the board

A defender removes a cell and can turn an open region into a forced corridor.

Completion is global

A legal individual path works only if every other pair can still connect and all remaining space can be covered.

Try it on a field

Open ROUTE on iPhone and change one path at a time. Every playable field is solver-validated, so a failure is useful evidence about corridor ownership, endpoint access, or coverage.
