Merge the microbes. Contain the outbreak. Petri Panic is a physics-packed merge puzzler set inside a glowing petri dish. Drop bacteria, bump matching cells together, and watch them merge into bigger, nastier strains — all the way up to the explosive SUPERBUG. Let them pile over the danger line, though, and the contamination timer starts ticking down... Three ways to play Classic — The pure merge experience. Climb the tiers, chase high scores, and set off SUPERBUG outbreaks that wipe the dish clean. Survival — No cell timers, just a relentless doomsday clock. Every merge buys a few more seconds. How long can you last? Arcade — Classic, but a random event strikes every 20 seconds: dish spins, bombs, rapid fire, double points, bouncy physics, and reality-bending glitches. Tools of the lab Antibiotic — dissolve the dead cells clogging your dish. Petri Heat — reset every cell's life timer. Dish Spin — tilt the whole dish and reshuffle the chaos. Features Chase achievements A friend's leaderboard for Classic mode 100% procedurally generated visuals and a chill, evolving lab soundtrack Satisfying chains, escalating combos, and screen-filling SUPERBUG outbreaks Accessibility built in: colorblind palettes, on-cell tier numbers, reduced-flash and reduced-motion options Easy to learn, tough to master. One more drop never hurt anyone. Probably.
