Research on SIGMA

Game-tree analysis and word research for SIGMA, with an explanation for each figure.

Optimal play

Opening with SIGMA, a proven-optimal strategy averages 3.72 guesses and ranks #6,312 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 #2,278 of the 7,453 openers that can still guarantee a solve within six guesses.

Our six-turn simulation says 3.68, 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.
