About Criticality

Criticality is an incremental clicker game about splitting atoms and triggering chain reactions. You play a hapless engineer caught in Cold War politics, working with a rickety reactor and volatile atoms in a series of high-stakes situations.

Trigger chain reactions

Click to fire a neutron. Atoms absorb it, split and detonate, creating chain reactions; longer chains earn more points. You spend points on reactor upgrades that boost neutron output and unlock mechanics, building up from small reactions to larger blasts. Push the reactor toward critical mass to earn rewards, while risking a meltdown.

Endings and upgrades

The game has four endings, over 300 upgrades and a prestige system with game-changing mechanics. It also features jazzy music, relaxing gameplay and atom popping.
