BPC stands for bacteria per click.
When the player taps on the main screen, he will produce Bacteria in the amount that is at least equal to the current BPC. The game starts with the player having just 1 BPC and it is primarily increased by purchasing Bacteria guns from the Bacteria colonies menu.
Mechanics such as Red Bacteria, critical hits, and tapping combos enable temporarily increasing BPC or producing more Bacteria than the current BPC would normally allow.
BPC can quickly reach large numbers, which are displayed using abbreviations or scientific notification, if it has been enabled in the settings menu.
BPC sources
BPC sources add some number to the base Bacteria production per tap.
They include Bacteria gun, which can be purchased from the Bacteria colonies menu, and Bacteria cannon, which can be purchased for Diamonds in the premium section.
BPC modifiers
BPC modifiers increase the current BPC by some percentage.
Most BPC modifiers are reset when attacking planets or entering a Black Hole, but others — such as the BPC bonus from Minerals — are permanent.
