Flood-fill frontiers
Recolor a connected region to absorb matching neighbors. The choice determines both current growth and the next frontier.
The player's decision
Absorb the largest nearby patch or take a small corridor toward a distant region?
Original scenario
Original setup: a large yellow patch is a dead end, while a small green bridge reaches two regions.
Start with this prototype
Build a 5×5 three-color map expanding from the top-left with a solver-verified move limit. Show frontier, moves and undo. Unify the board; do not pair random boards with arbitrary tight limits.
Change one variable
Keep the map fixed and vary move allowance, separating solvability from guidance.
What to observe in a playtest
Does selecting the current color cost no move? Test narrow corridors and a fully connected board.
Take the full design card
Includes rules, scope, tuning questions and sources for further planning. It does not create a project automatically.

Common pitfall
Absorbing disconnected matching tiles removes frontier planning.
