Cookie Clicker

Cookie Clicker is a cool game. You just only click to play and earning a single cookie per click. You can then spend earned cookies upon purchasing assets such as "cursors" and other "buildings" that automatically produce cookies. The game has no ending, it has hundreds of achievements, and users may aim to reach milestone numbers of cookies. Prices increase exponentially, each asset costing 15% more than the last-purchased asset of the same type. Achievements can be earned by completing various tasks or goals. Have fun.
