Understand this puzzle

Choose a worked example after solving, or open just the part you need. These explanations are calculated from this recorded puzzle.

Compare the letters after solving

For NITRO, the pattern N__R_ fixes positions 1 and 4. It matches 15 of 14757 words in our independent five-letter dictionary: NACRE, NAIRA, NAIRU, NARRA, NARRE, NEARS, NEGRI, NIGRE ….

4 dictionary words differ at exactly one position: NITRE, NITRY, NITTO, VITRO. Check that differing position before treating a familiar spelling as the solution.

This comparison explains spelling constraints. These are dictionary matches, not the publisher's accepted guesses or historical answer pool.

Why these alphabetical bounds work

NITRO comes after NITRE: the first different letter is at position 5, where NITRO has O and NITRE has E. Earlier positions match.

NITRO comes before NITRY: the first different letter is at position 5, where NITRO has O and NITRY has Y. Earlier positions match.

These neighbours come from our independent dictionary. They illustrate alphabetical comparison, not an official distance score or a recorded play session.

Alphabetical distance counts words in a dictionary, rather than the number of letters between guesses. Your game's dictionary can differ from this helper's.
