iCookieClicker is an "incrementer" game.The point of the game is to bake cookies by tapping on a giant cookie until you have enough cookies to buy upgrades. The seemingly endless gameplay makes it a game that can last an indefinite amount of time, or at least until your device can no longer run it.
