Periodically, Golden Cookies may appear, and when clicked, confer various bonuses (flat +cookies, or additional multiplier of cookie production for 77 seconds). I’ve noticed other people have many more Golden Cookie clicks than I do at my point in the game.

- How often do Golden Cookies appear?
- How long are they available for clicking before disappearing?
- Are Golden Cookies more likely to appear if the game has been running a long time without a Golden Cookie click?
- How is the flat +cookie bonus calculated?
- Do the bonuses always alternate between clicks, or between appearances? (flat bonus vs percentage increase)

**Answer**

Without any upgrades or anything, a Golden Cookie spawns `m`

minutes after the last one disappeared, where `m`

is a random number between 5 and 15. Each of the upgrades **Lucky day** and **Serendipity** cut that time in half, and the debug upgrade **Gold hoard** makes them spawn pretty much constantly instead. Also, if your last cookie gave you a cookie chain, then the next one spawns 3 seconds later. This means that you are *not* more likely to get a Golden Cookie if you haven’t clicked on one in a while.

Without any upgrades, again, a Golden Cookie lasts for 13 seconds before disappearing. The **Lucky day** and **Serendipity** upgrades both double that. If your last cookie gave you a cookie chain, then it disappears after 6 seconds instead.

When you get what appears to be a flat number of cookies, it either gives you 15% of your banked cookies or the equivalent of 20 minutes of cookie production, whichever is lower.

The bonus you get is randomly chosen each time you click the cookie. It normally chooses between **Frenzy**, which multiplies your production by 7, and **Lucky**, which gives you cookies as I just described. There is also a small chance of getting a **Click frenzy**, which multiplies your cookies per click by 777, and an even smaller chance of getting a **Cookie chain**, which gives you 6 the first time you get it, 66 the second time, etc. until you get something else. As Michael Madsen’s answer points out, the effects *appear* to alternate because every time you click a golden cookie, there’s an 80% chance that it will remove the previous effect from the list of possible effects before it picks which one actually happens.

Once the Grandmapocalypse begins, you also have a chance of getting **Ruin**, which makes you lose half as many cookies as you would gain from a **Lucky** cookie, **Clot**, which cuts your production in half, and **Elder Frenzy**, which multiplies your production by 666 for a few seconds.
