Petri Panic

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 random events strike as the clock ticks down! Don’t forget to merge every few drops to keep your bonus multiplier going up.

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

• 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.
