About this game
The nuclear idle tycoon simulator is back — and it's free.
Build your own power company from the ground up. Manage heat, optimize production, and grow a massive energy empire. In Reactor 2, you don't just construct power plants — you power an entire evolving city.
Master the system, discover your best strategy, and scale your profits to become a true industrial billionaire.
⚡ BUILD, POWER, AND EXPAND
Start small with basic wind turbines and grow into a high-efficiency nuclear power network.
Your mission is simple — supply energy to the city. Your challenge? Control the heat.
• Produce heat with diverse power sources
• Convert heat into electricity for the city
• Cool your systems to avoid production shutdowns
Balance everything perfectly to achieve maximum efficiency.
😌 RELAXED STRATEGY, NO PUNISHMENT
Reactor 2 is an idle clicker game built for thinkers, not masochists.
Your reactors never explode or reset your progress — they simply pause and cool down. This creates a no-loss, strategy-first experience where you experiment, optimize, and build at your own pace.
🔬 RESEARCH THE FUTURE
Unlock dozens of technologies and push your power empire forward.
• Renewables: Solar, Wind, Hydro, Tidal
• Advanced Tech: Nuclear, Fusion, Arc Reactors

Every upgrade deepens your strategy and multiplies your profits.
