Setup and opening position
A deterministic secret contains four values from one through four, with repetition allowed. Earlier guess rows show each guess plus exact and color-only match totals.

Complete guide
Code Guess Puzzle is a complete browser implementation with its own versioned rules profile. Deduce a four-position code using four symbols from prior exact-position and correct-color feedback, then submit the one code consistent with every clue row.
A deterministic secret contains four values from one through four, with repetition allowed. Earlier guess rows show each guess plus exact and color-only match totals.
Submit any four-symbol code whose values are between one and four. Feedback counts exact-position matches first, then matching colors in different positions without double counting.
Submit the unique secret code that satisfies every immutable feedback row generated for the puzzle. Before submitting the final candidate, recompute both feedback numbers against every row; the bounded solver has verified that exactly one of the 256 codes survives.
Use exact matches to lock positions, then compare repeated-symbol totals across clue rows to eliminate codes that overuse a color or place it incorrectly. Color-only matches exclude exact matches and cannot reuse the same symbol twice, so simply adding raw color frequencies produces impossible candidate codes.
