Black Hole Reactor Simulator
A Roblox experience owned by TixBux ROBUX.
Description (written by the developer; not a statement by this register)
Control a black hole reactor and keep it stable. Feed the singularity, regulate gravitational containment, balance Hawking radiation and energy output, and meet the city's power demand before the reactor collapses. 🕳️ Ignite the singularity and ramp up the reactor to full power 🌌 Monitor gravity, radiation, and core stability — trigger EMERGENCY CONTAINMENT when things go wrong ⚡ Complete energy contracts and maintain steady output to earn credits 🔧 Upgrade magnetic containment, radiation converters, and energy turbines to harness more power safely ⚠️ Survive containment failures, gravity surges, and energy demand spikes as the reactor pushes beyond its limits Harness the power of a black hole to build the ultimate energy plant — keep the singularity under control, or risk a catastrophic containment breach.

Growth
Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
