Every click produces one cookie. As players get more cookies, they can trade those cookies for new automated methods of cookie productions, from cursors that click the cookie once every ten seconds for the player and friendly grandmas who will bake extra cookies to time machines that bring cookies from the past and antimatter condensers that turn all the antimatter in the universe into cookies on a regular basis.
There are ten different items that the player can purchase to increase automated cookie production, all of which increase in cost with every unit the player's purchase. Building items can be sold back at any time for half of its current price and each building item can be upgraded to increase its efficiency or the number of cookies produced per second.
