A fire spreads across the grid. Drag to build walls and seal it into a closed pocket — sealed fire suffocates, and you score for every ember trapped.
Small seals are safe points. Letting a fire grow before you trap it pays far more — but one careless second and it overruns you. New fires are telegraphed before they ignite; mind the wind.

Seal fire into a closed pocket to capture it. Bigger captures escalate: SPARK → BLAZE → INFERNO → FIRESTORM. Chain captures quickly to build a combo multiplier. Walls refund when their pocket is captured.
