First-turn measures

All four describe CHIRO 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.

4.83 Entropy (bits)
169 Avg remaining
0.0% Exact match
92.9% Avg ruled out
Higher first-turn entropy than about 74% of evaluated openers

Optimal play

Opening with CHIRO, a proven-optimal strategy averages 3.69 guesses and ranks #4,123 of 14,855 legal openers. The best proven opener, TARSE, averages 3.55.

Our six-turn simulation says 3.62, at or below the proven-optimal 3.69, 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.
