About this game

Radon Glow is a hands-on sub-slab mitigation puzzle. Radon pools in hidden blind
spots under the basement slab. Core suction pits where the pressure field can
actually reach the haze, route vent pipes to the outdoor stack (every elbow adds
pressure loss), and pick a fan speed: too weak will not cover the rooms, too
strong stirs up extra soil gas. Then run the radon test and get every room at
or below 4.0 pCi/L.

Twelve missions with growing floor plans, stronger soil emission, and
load-bearing no-drill zones. Earn coins and stars, then spend them in the Field
Supply shop on six working tools: longer core bits, flex duct kits, sealed
manifolds, radon sniffers, pressure boosters, and coin doublers. Progress and
gear are saved on the device.
