Orteil created Cookie Clicker on August 8, 2013. The game was fairly simple at first, and by the 24th of the same month, he made a new version of the game at a different URL. The old game would later be known as "Cookie Clicker Classic".
The New Cookie ClickerEdit
After creating the new Cookie Clicker (also known as the 1.0 Update), Orteil continued to add new features to the game, such as upgrades and achievements. The game is still in constant update, with large updates happening around holidays such as Halloween, Christmas, Valentine's Day, April Fools' Day, and Easter. The game's current link can be found here. The game's source code can be found here.
There are 16 buildings. From lowest to highest starting cost: cursors, grandmas, farms, mines, factories, banks, temples, wizard towers, shipments, alchemy labs, portals, time machines, antimatter condensers, prisms, chancemakers, and fractal engines.
