Optimal play
Opening with UMBOS, a proven-optimal strategy averages 3.79 guesses and ranks #10,189 of 14,855 legal openers. The best proven opener, TARSE, averages 3.55.
In hard mode it averages 3.88 guesses at best and is rank #3,829 of the 7,453 openers that can still guarantee a solve within six guesses.
Our six-turn simulation says 3.75, at or below the proven-optimal 3.79, 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.
