Petri Defence

Place cells. Stop the germs.

Free · Designed for iPad. Not verified for macOS.

Two ways to play: quick Relaxed levels with a reward every few minutes, or Hardcore puzzle boards with a boss to beat. Plus a new Daily level every day. Germs are heading for the heart. Place your cells, shape their path and stop every last one. Petri Defence is a small tower defence game that is all about where you put things. Each level is a petri dish, a handful of cells and a stream of germs. Put a T-cell where it matters, aim an Antibody down the path, slow them with a Net or block the way with a Platelet. Then press Start and watch your plan work. Or not, and try again. TWO WAYS TO PLAY • Relaxed: endless one-minute levels, three stars to chase and a gift box every few minutes. Easy to pick up, hard to put down. • Hardcore: hand-made puzzle boards with a par to beat and a boss at the end of the chapter. You will lose. You will learn. Then you will find the answer. A NEW LEVEL EVERY DAY • The Daily level has its own twist each day. Keep your streak going. GERMS WITH IDEAS OF THEIR OWN Tough ones, fast ones, shelled ones, germs that split in two when they pop and Chewers that bite through your walls. Each one makes you rethink your layout. FAIR AND FRIENDLY • No energy timers and no waiting. Play as long as you like. • Earn ATP by playing and spend it on hats, pop effects and colours for your cells. Looks only: nothing makes the game easier. • Works offline. Your progress stays on your device. Ideas or bugs? Write to hello@petridefence.com
