How NANOS performs as a guess

Wordle accepts NANOS as a guess, but the solver does not list it as a possible answer.

Played as an opener, it lands at least one colored tile in 80.2% of games, misses completely in 19.8%, and leaves about 199 possible answers on average.

In the previous complete opener benchmark, it ranks #9,534 of 14,855 openers, averaging 3.75 guesses in games solved within six turns.

First-turn measures

All four describe NANOS 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.

4.33 Entropy (bits)
199 Avg remaining
0.0% Exact match
91.6% Avg ruled out
Higher first-turn entropy than about 41% of evaluated openers
1.61 bits below the highest measured first-turn entropy (~5.95 bits)

As an opening guess: previous benchmark

How NANOS performed in the previous complete opener benchmark, against its captured answer snapshot. These research figures are separate from today's solver recommendations. See the data page for the method.

3.75 Avg guesses
99.83% Solved within six
0.70 Spread of game lengths
#9,534 Rank among openers
Opening with NANOS left 4 of the snapshot's answers unsolved after six guesses. A spread of 0.70 means those games clustered within about 0.70 of a guess of the 3.75 average. It ranks #9,534 of 14,855 openers by average guesses in games solved within six.

Research on NANOS

Optimal play

Opening with NANOS, a proven-optimal strategy averages 3.80 guesses and ranks #10,759 of 14,855 legal openers. The best proven opener, TARSE, averages 3.55.

In hard mode it averages 3.95 guesses at best and is rank #5,212 of the 7,453 openers that can still guarantee a solve within six guesses.

Our six-turn simulation says 3.75, at or below the proven-optimal 3.80, 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.
