What is the answer to rule 6 in The Password Games?

Your total character count must be a prime number: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, or 53 and beyond. Add or remove characters, ideally special characters, until the count lands on a prime.

Do emoji count as one character or two for the prime length rule?

One. The game counts user-perceived characters, so every emoji is exactly 1 toward your length. Count what you see, not bytes.

Directive 6: Prime Length (Hints & Answer)

Hint first (no full spoiler): Count every character, emoji included, and make sure the total is a number that refuses to be divided.

Directive 6 requires your total password length to be a prime number. The Committee accepts 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, and so on. Composite numbers are divisible, and the Committee does not trust anything that can be split.

Emoji count as 1 character each. Count what your eyes see.

The full solution

Count your characters. If the total is prime, you pass. If not, add or remove characters until it is. The nearest primes are never far apart, so the fix is usually one or two characters.

Friday7 (7 characters, prime, APPROVED)
Friday9! (8 characters, DENIED; 9 is 3x3, so pad three specials to reach 11: Friday9!:-) passes)
Friday9!venus (13 characters, prime, APPROVED)

Keep this prime list where you can see it: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53. Most complete vault runs finish somewhere in the 40s or low 50s.

The critical technique, the one you will use a dozen times: pad with special characters. Specials are not letters and not digits, so adding them changes your length and nothing else. No digit sum disturbance for Directive 8, no Scrabble score change, no letter cap trouble. When your length is stranded between primes, a ! or two walks you home. See Directive 4 for the full argument.

Padding with digits or letters also works arithmetically, but each has side effects that come due later. Punctuation has none. The Committee accepts bribes only in punctuation.

What breaks later

Directive 6 is the most-violated rule in the game, by design. Nearly every later directive forces new characters into your password, and every insertion risks knocking you off a prime:

Rules 9, 10, 13, and 23 each inject required digits or content. Each arrival is a fresh length audit, and usually a fresh DENIED stamp on this directive while you re-pad.
Directive 8 creates a two-variable problem: adjustment digits fix the digit sum but move the length, and padding fixes the length without touching the sum. Solve the digit sum first, then pad to prime. Always in that order.
Act III letter caps make letter-padding actively dangerous, which is why the punctuation strategy is not just convenient but eventually mandatory.

Develop the habit now: after every single edit for any rule, recount and re-check the prime. Players who batch their edits and check once at the end spend a lot of quality time with the DENIED stamp.

Stamp: APPROVED, at this exact length, and not one character otherwise.
