No that makes sense, I just thought you had to guess the color and then get lucky, I didn't know you had to go through 12 portals, I thought there were 12 colors with 415 exit portals each, and one brought you to the hole haha, jesus christ though, has anyone managed to get it?

No, each 1/415 roll happens independently.
To win you need to get the correct portal 12 times in a row.
To get the result you need to multiply the individual probabilities together.
This means getting the correct portal 2 times in a row would be this:
(1/415) x (1/415) = (1/415)^2 = 1/172225.

you can compare it to rolling a 12 sided die vs two 6 sided dice.
The probability of rolling a 12 with the 12 sided die is 1/12.
The probability of rolling a 12 with the two 6 sided dice is (1/6) x (1/6) = 1/36 .

Um.. wouldn't this be a 1/4980 chance since it'd be 415x12 for a total of 4,980 portals, but maybe i'm missing something here lol
