Game
Critical Mass
Guess the science term before the reaction goes critical.
Science word hangman for the browser - stabilize the experiment before the risk meter hits critical mass. Built for scientists and the science-curious.
One username: tap Sign in on the menu. The same name you use in Plankwalk or The Chart Room carries your lab notes.
After every win or loss you get a Fact Card (short definition + field). Modes include Classic and Daily Hypothesis (same term for everyone that UTC day). Protocol Charts is the classified floor plan: Classic wins ink the Solvent Bench, Daily Hypothesis inks Half-Life, and a clean run (0–1 miss) inks Core Assembly. Finish the chart to stamp Isotope on this device.
