Radium Shine

Radium Shine puts you in charge of a luminous coating workshop after dark.

Each shift brings a new order: a dive watch dial, a fire exit sign, or a cinema floor marker, each with its own brightness and glow-duration spec. Run the full production line with your own hands:

1. SLURRY MIX - lock the needle in the green window for the perfect powder-to-oil ratio.
2. SCREEN PRINT - pull the squeegee and release at the ideal coating thickness. Thickness decides how bright the part will glow.
3. CURING OVEN - vent heat with quick taps and hold the temperature inside the curing band.
4. HOOD ASSEMBLY - time your tap as the pointer sweeps across the mark.
5. DARK ROOM - inspect the finished part. Payout equals initial brightness times glow duration.

Watch out for charged dust grains drifting onto wet coatings; tap them away before they land.

Spend your coins on six real upgrades: a humidity room that steadies the slurry, a precision printer with wider lock windows, an online photometer that plots the live decay curve, hi-glow phosphor for brighter parts, a UV fast oven for quicker curing, and a fire contract that boosts every payout. All upgrades are permanent and saved.

All sound effects are synthesized at runtime. No ads, no accounts, just the quiet hum of the workshop and the glow of a job well done.
