Satan appears to you and offers you a gamble. If you accept, he rolls a roulette wheel with a chance of 1 per Graham's number ( https://en.wikipedia.org/wiki/Graham%27s_number ) of you going to hell to be tortured in gruesome ways for eternity.

If you win the spin, at probability (G-1)/G (very near 100%), you get 1 million dollars. You can repeat the spin as many times as you like, each time either gaining a million bucks or hitting the negative jackpot which condemns you to infinitely lasting torture.

How many times do you spin?
