First-turn measures

All four describe MUCIN used as an opening guess. Entropy is the same idea as “avg ruled out” on a log scale: a higher number means the guess splits the possible answers into more, smaller groups.

4.35 Entropy (bits)
271 Avg remaining
0.0% Exact match
88.6% Avg ruled out
Higher first-turn entropy than about 42% of evaluated openers
1.59 bits below the highest measured first-turn entropy (~5.95 bits)

Optimal play

Opening with MUCIN, a proven-optimal strategy averages 3.72 guesses and ranks #6,404 of 14,855 legal openers. The best proven opener, TARSE, averages 3.55.

In hard mode it averages 3.83 guesses at best and is rank #2,377 of the 7,453 openers that can still guarantee a solve within six guesses.

Our six-turn simulation says 3.65, at or below the proven-optimal 3.72, 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.
