Research on CLAST

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

Optimal play

Opening with CLAST, a proven-optimal strategy averages 3.60 guesses and ranks #115 of 14,855 legal openers. The best proven opener, TARSE, averages 3.55.

In hard mode it averages 3.70 guesses at best and is rank #9 of the 7,453 openers that can still guarantee a solve within six guesses.

Our six-turn simulation says 3.51, at or below the proven-optimal 3.60, 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.
