Saw a Guide with various numbers and thought this might be a nice addition. The expected number of flips to get 10 heads in a row is, counterintuitively, NOT simply the inverse of the probability, so it's worth mentioning separately.

20% Chance: 12,207,030 flips

25% Chance: 1,398,100 flips

30% Chance: 241,929 flips

35% Chance: 55,770 flips

40% Chance: 15,893 flips

45% Chance: 5,338 flips

50% Chance: 2,046 flips

55% Chance: 876 flips

60% Chance: 411 flips

Interesting! FateZiggy did an automated stream which was running 24/7 trying to get an ending at 20% heads chance. It was achieved after 1,765,752 flips.

I wish we had a little category for the most tails in a row with a little leaderboard lol would be hilarious to see how bad it gets. I hit a 60% tails 24 times in a row today and hit alt F4 XD

@Xialdin This could be done. If you send me a video of your worst tails streak or share it in the Discord I can create the category.
