First-turn measures

All four describe NISIN 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.

3.40 Entropy (bits)
458 Avg remaining
0.0% Exact match
80.7% Avg ruled out
Higher first-turn entropy than about 5% of evaluated openers
2.55 bits below the highest measured first-turn entropy (~5.95 bits)

Optimal play

Opening with NISIN, a proven-optimal strategy averages 3.93 guesses and ranks #14,270 of 14,855 legal openers. The best proven opener, TARSE, averages 3.55.

In hard mode it averages 4.10 guesses at best and is rank #7,132 of the 7,453 openers that can still guarantee a solve within six guesses.

Our six-turn simulation says 3.90, at or below the proven-optimal 3.93, 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.
