Cookie Clicker

In the addictive browser game Cookie Clicker, created by French developer "Orteil", your mission is to rapidly bake cookies, accumulate a vast cookie stash, and collect as much milk as possible - with no definitive end in sight. The game begins with a single, giant cookie that yields one cookie each time it's clicked. As your cookie collection grows, you can invest in upgrades that automatically bake cookies, creating an endless loop of cookie production that can persist indefinitely.
