Answer

You can simply write the definition of the block using the definition from my thought:

// assume that there is a function numbers(a, b) that returns numbers from a to b
function checkPasscode(passcode) {
  const allPrimeNumbers = numbers(1, passcode).filter(isPrime);
  // If the passcode is a number between the 96th and 97th prime number
  // and the passcode is 4 numbers ahead of a specific prime number,
  // then the passcode is right.
  return (
    allPrimeNumbers.length === 96 &&
    allPrimeNumbers.at(-1) === passcode - 4
  );
}

You can see that if the passcode is 4 numbers ahead the 96th prime number.

Therefore, the passcode is 507.

From my thought:

From this site:

The following table lists the first 1,000 primes, with 20 columns of consecutive primes in each of the 50 rows.

nice

You should blue the passcode so then people who want to give it a try don’t see the answer.

Like this:
The passcode it 507
The passcode is [spoiler]insert passcode[/spoiler]

5

The second one

The hints are encoded using Unicode.

I can’t solve the second passcode, it’s so hard. maybe another person could help

8

Hint: It is a 6-digit number starting with 6.

9

I found it: 634114.

The surprising thing is that I bypassed all of those

I wrapped it

The third one

14

when trying to brute force it (srry, but i dont have the mental capacity for solving stuff like this without brute force), i came upon this error

EDIT: it errors at values >= 10

15

99 doesn’t error

16

i know how i can brute force it now… thanks!

17

nvm, i tried inputting large sequences of 9’s and it didn’t work (the highest i tried before giving up was 10048 9’s)

18

I just made a script that counts up, tries the number, and moves on if it errors or is incorrect

Its still running. It’s at around 136000 right now

19

ok, that’s what i was trying to do, but the password tester shouldn’t give errors in the first place!

This might be intentional, but you don’t need to split the password just to get a letter. There’s already special blocks for length and letter for strings
