The Golden Cookie (not to be confused with the Red Cookie) is an object that shows up on the screen in a random position during normal gameplay. It remains on the screen for 13 seconds, slowly fading into nothing (the time it stays on-screen can be increased, see below). If it is clicked before it disappears entirely, it will grant the player one of four semi-random outcomes.
Note: These numbers only apply exactly for your first cookie. There is an 80% chance that the cookie will be forced to be different from the previous effect. All chances are calculated from the source code.
49.00417% to get "Frenzy": Get x7 cookie production for 77 seconds. Affects Cookies per Second, but does NOT affect Cookies per Click (although it indirectly affects cookies per click with the Plastic/Iron/Titanium/Adamantium Mouse upgrades).
49.00417% to get "Lucky!": Get an instant boost of cookies equal to 10% of the current cookies plus 13, or 20 minutes worth of cookies (which is CPS*1200) plus 13, whichever is less. (Stacks with Frenzy; if Frenzy is active when you get "Lucky," you can potentially get 20x7 = 140 minutes worth of cookies)
1.6625% to get "Clicking Frenzy": Gives x777 cookies per click for 13 seconds. Only works for manual clicking. Stacks with Frenzy. If Frenzy is active when you get Clicking Frenzy, you can potentially get x5439 cookies per click.
0.32916% to start a "Cookie Chain": The first cookie you click in the chain will reward you with +6 cookies, and 3 seconds after being clicked another cookie will appear which grants +66 cookies, and then the third +666 cookies, and so on. Every time you click the golden cookie, after it rewards cookies, it runs a couple checks. The first five will always appear (as long as you don't miss clicking them), but after that, there are a few things that can cause the chain to break
