Vault #4: Star, Star, Triangle, Diamond — the solution

The Vault code from August 18, 2026: 4 symbols from a palette of 5, nine guesses, par 5. Below, the code and a crack that keeps only what fits.

The puzzle

A code 4 symbols long, each drawn from circle, hexagon, diamond, star and triangle — repeats allowed. Every guess comes back as three counts: exact (right symbol, right slot), near (right symbol, within one slot of where it was played) and far (in the code, but wider away).

The walkthrough

The strategy the help sheet teaches: after each answer, keep every code that still fits every count so far, and guess one of them. Par was measured the same way, so a clean run lands on it or just under. Here it takes 4 guesses, 1 under par.

1. circle, circle, hexagon, hexagon — 0 exact, 0 near, 0 far. 625 codes fit before this guess; 81 fit after it.
2. star, diamond, star, triangle — 1 exact, 2 near, 1 far. 81 codes fit before this guess; 2 fit after it.
3. star, triangle, diamond, star — 1 exact, 2 near, 1 far. 2 codes fit before this guess; 1 fit after it.
4. star, star, triangle, diamond — 4 exact — cracked.

The answer

The code was star, star, triangle, diamond — the star twice.
