Factories
If you want to increase your cookie production considerably you will need to invest in Factories. The Factory is the fourth cheapest building you can purchase and produces cookies at a base rate of 10 cookies per second. When they have been fully upgraded they will each produce 224 cookies per second. Having 50 of them will unlock Dungeons (thses can only be unlocked on the Beta Version or by using cheats).
