Instead of the Gold Cookies there will sometimes appear red cookies, and they can be pretty annoying since the can cut your CPS by half for 66 seconds or just make you lose a flat amount. But they can also give you a flat amount of cookies and the chance is higher to get a cookie chain (first cookie 6 next 66 the one after 666) and with every cookie you click the chance is lower that another will appear within the next 3 seconds. (I had this 2 times and just got to 66 666 666 the better run)
Just do it you wanna go on anyways right?
