Optimal play
Opening with OPSIN, a proven-optimal strategy averages 3.71 guesses and ranks #5,243 of 14,855 legal openers. The best proven opener, TARSE, averages 3.55.
In hard mode it averages 3.80 guesses at best and is rank #1,435 of the 7,453 openers that can still guarantee a solve within six guesses.
Our six-turn simulation says 3.62, at or below the proven-optimal 3.71, 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
