Tokamak — Chain Reaction

Tokamak: Chain Reaction is a card game about running a fusion reactor without melting it down. You seat four plasma states into the core and it shows you which fusion protocols your poker hand can fire. Outputs and surviving cards stay seated, so a clean ignition can fire again — the chain the title is named for. Heat builds with every reaction; cross the containment limit and the reactor fails. I wanted to build a problem-solving game where the rules are clear but hidden — you work out what gives you the best chance at success, and then, like life, some of it is just random.
