The Password Game

Unfortunately, I think I haven't been able to see every rule in my research, but (Thanks to fellow tildes users for assisting!) here's every rule from 16 and beyond:

Rule 16 says "Your password must include the best move in algebraic chess notation." and shows a chess board, with a randomized board state. This is where I personally failed as I am not familiar enough with chess to realistically solve it.

Rule 17 says "🥚← This is my chicken Paul. He hasn't hatched yet, please put him in your password and keep him safe."

Rule 18 says "The elements in your password must have atomic numbers that add up to 200."

(at some point, probably here, your entry field is given some formatting tools)

Rule 19 says "All the vowels in your password must be bolded."

Rule 20 says "Oh no! Your password is on fire. Quick, put it out!" and fills up a bunch of fire emojis in your password input box. Apparently, Paul can burn if you do not clear the fires fast enough.

Rule 21 says "Your password is not strong enough 🏋️" and I'm not sure what the solution is but it might be just spamming a bunch of 🏋️ 🏋️ 🏋️ 🏋️ 🏋️

Rule 22 - courtesy of @em-dash with suspected possible variants:
Your password must contain one of the following affirmations:
I am loved
I am worthy
I am enough

Rule 23 says "Paul has hatched! Please don't forget to feed him, he eats three 🐛 every minute." - At this point, I believe the egg emoji is automatically replaced with a chicken emoji, and you will have to add 🐛🐛🐛 to the password every minute while you're solving other rules or it will fail. As Paul eats them, the bugs actually disappear from your password in real time. You can overfeed him by trying to add a large amount too fast.

Rule 24 says "Your password must include the URL of a 24 minute 7 second long YouTube video." - have fun searching for one while keeping Paul fed... It's also likely to fuck up your roman numerals or other prior answers. Also, the time is randomized, so you can't just borrow someone else's answer which solved, as yours will likely require a different duration video.

Rule 25 says "A sacrifice must be made. Pick 2 letters that you will no longer be able to use." and a keyboard is displayed where you click 2 letters and then click Sacrifice.

Rule 26: Your password must contain twice as many italic characters as bold (26 through 28 courtesy of @pizardwenis96)

Rule 27: At least 30% of your password must be in the Wingdings font

Rule 28: Your password must include this color in hex

Rule 29 - All roman numerals must be in Times New Roman. (thanks to @SteeeveTheSteve for this one)

Rule 30 says "The font size of every digit must be equal to its square."

Rule 31 says "Every instance of the same letter must have a different font size.

Rule 32 says "Your password must include the length of your password.

Rule 33 says "The length of your password must be a prime number."

Rule 34 says "Uhhh let's skip this one." and is automatically checked off

Rule 35 says "Your password must include the current time." so it will basically infinitely require updating.

At the end, which is after Rule 35, it asks you to confirm your password, basically, by opening a second text field and starting a bomb, which supposedly is 2 minutes. I suspect the player may not be allowed to copy and paste, here. The password must be entered exactly correctly as a copy of the first, and I'm not sure but I suspect the temporal rules may still be maintained, such as the current time and feeding Paul.

The country, chess, youtube, and possibly elements of other rules are randomized so you won't be able to rely on other people's answers.

Some users reported that an illegal move on the chessboard was part of the captcha, producing an unwinnable condition, but apparently the captcha can be rerolled at any time.

Some users reported that the country they received in Rule 14 had a letter that made their roman numeral rule 9 impossible (in the example, it was the C in "Cambodia" putting their roman numeral total well above their required 35.) As it turns out, it will accept the country name in lowercase, avoiding this issue.

One user supposedly completed the game, but did not report how many rules there were total. Seems to be 35 rules and then the retype confirmation.
