Decay

Decay is an incremental game about creating atomic nuclei with a particle launcher and discovering isotopes. You configure the launcher with protons and neutrons, then launch a particle to see the resulting nucleus and its decay chain. Nuclei can become larger and more unstable, producing longer and more complex decay chains.

Run experiments

Successful experiments earn money, which you spend on upgrades to improve your laboratory and expand its capabilities. You can build additional test chambers and automate them to run multiple experiments in parallel.

Discover isotopes

The game includes hundreds of isotopes to discover. You can observe real atomic decay chains, including how an isotope forms and how it may decay.
