Ruby Ridge

Ruby Ridge puts you in charge of a Verneuil flame-fusion furnace. Slide the left lever to tune the hydrogen-oxygen flame and the right lever to meter alumina powder. Keep both inside the sweet zone and your boule climbs tall with pure, vivid color. Run too hot with too much powder and the crystal cracks apart; starve it and the boule slumps into ruin.

Tap the CHROME pulse at the perfect balanced moment to dope your crystal toward legendary pigeon-blood grade. Finished boules are scored by height times color grade times a crack-free bonus, and consecutive perfect runs build a streak bonus of coins.

Spend coins in the Torch Shop on six working upgrades: two flame skins, a Flame Stabilizer, a Precision Hopper, a Grade Spectrometer and a Cooling Jacket. Every item changes real gameplay. All sound effects are synthesized live on your device.

Tune the flame. Trust your hands. Grow the perfect ruby.
