About the Game
A Foundry That Never Sleeps
QuantumBonusEmpire starts you with a single hand-cranked copper furnace on the banks of the Torrens. Every ingot you pour feeds a compounding bonus economy — reinvest into conveyor lines, hire foremen, and watch your output climb even while your phone is in your pocket.
We are a seven-person studio working out of a warehouse just off Hindmarsh Square in Adelaide. The game ships free with no forced ads; a one-time Foundry Pass unlock is AUD $6.99 for players who want to skip the timers.

Tap the furnace to melt raw ore into copper bars. Each bar sells instantly for Quantum Credits — your first currency.

- 04
Prestige & Repeat
Reset for Empire Cores that permanently boost every future run. Nine prestige tiers keep the loop rewarding for hundreds of hours.

Rare prestige tech
Late-game amethyst reactors convert waste heat into bonus multipliers. Chain three reactors to trigger a Quantum Surge and double output for 90 seconds.
No Forced Ads
Play on your terms
Ads are strictly opt-in for a temporary boost. The AUD $6.99 Foundry Pass removes timers entirely — buy it once and it is yours across all your devices.
