Donut Clicker is a free online idle clicker game where you click donuts, buy bakery buildings, unlock upgrades, and grow your production. Play the donut game in your browser and see how big you can make your bakery.
Click the main donut with the left mouse button to earn donuts, then use them to improve your bakery. At first, you'll do most of the clicking yourself. Later, your buildings take over more of the work.
The first few minutes are simple. Click, earn, buy something, then click some more. Once you have a few producers running, donuts start coming in without you having to do all the work.
That's when the Donut Clicker game becomes much more satisfying. You can leave the bakery running for a while, come back, and suddenly have enough donuts for something you couldn't afford before.

As production increases in Donut Clicker, prices rise too. A building that looked expensive earlier can eventually become an easy purchase.
There are also plenty of upgrades and achievements to work through. You can check your stats, customise the bakery with different names, skins, and backgrounds, and keep pushing toward prestige.
It is tempting to buy something every time you have enough donuts. Sometimes that's the right move, but not always.
Sometimes the cheaper building is worth buying just to get production moving again. Other times, it makes more sense to save for a better upgrade. A Golden Donut can throw off that plan when one appears while you're saving.
