Optimal play

Opening with COSET, a proven-optimal strategy averages 3.60 guesses and ranks #196 of 14,855 legal openers. The best proven opener, TARSE, averages 3.55.

No guaranteed hard-mode solve In hard mode, no strategy that opens with COSET can guarantee a solve within six guesses.

Our six-turn simulation says 3.60, at or below the proven-optimal 3.60, because the two figures score different answer lists.

These figures come from exhaustive game-tree search and are exact for the NYT lists of July 2023 (3,158 answers). They do not use the site's working answer pool.

Familiarity and learning

Frequency
COSET sits in the rare band of the wordfreq scale, appearing less than once per million words of written English; the band marks it as a word few players will have met in print.
