Full description

Inspired by real simulation tools used by nuclear engineers, Criticality Idle simulates nuclear reactor physics in a fun way that anyone can understand. Work your way through various reactor layouts, from realistic to silly, and everything in between. Reactor components include fuel, control rods, water, graphite, reflectors, and neutrons, all of which have multiple upgrades to increase power and income. Simulator particle limit can be adjusted based on your device capabilities while still maintaining accurate power and income levels. Early access out now! New reactors to be added weekly!
