About Bacteria
Dive into a microscopic puzzle world in Bacteria. Touch and detonate organisms, setting off chain reactions to clear each level. Plan your moves strategically to wipe out every bacterium with limited explosions. Enjoy progressively challenging levels and addictive gameplay that tests your timing and precision skills.
It's a focused puzzle game made for fans of the genre. It's tuned to load fast and play smoothly whether you've got five minutes or an hour.
A couple of things help once you get going: Watch for combos: clearing pieces in chains usually scores more than chasing the timer. When you are stuck, undo the last move and look at the board again instead of forcing a fix.
Add Bacteria to your break rotation. It's free on Glaze Games, loads fast, and saves nothing you didn't ask it to.
