About the project

Add an anonymous result and difficulty rating to the public, aggregate research dataset.

We send only this answer word for puzzle verification, the puzzle number, result, difficulty vote, Hard Mode flag, timezone and a random one-puzzle receipt token. The Observatory stores no answer word, grid, guesses, account, email, IP-derived ID or reusable player identifier. The puzzle-specific receipt prevents duplicate submissions and permits withdrawal; anyone with that token can withdraw, so keep browser-data exports private. See the privacy details.

First-turn measures

All four describe KEFIR 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.

4.48 Entropy (bits)
186 Avg remaining
0.04% Exact match
92.1% Avg ruled out
Higher first-turn entropy than about 51% of evaluated openers
1.46 bits below the highest measured first-turn entropy (~5.95 bits)

As an opening guess: previous benchmark

3.72 Avg guesses
99.92% Solved within six
0.70 Spread of game lengths
#7,805 Rank among openers
Opening with KEFIR left 2 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 3.72 average. It ranks #7,805 of 14,855 openers by average guesses in games solved within six.

The science of KEFIR

What game-tree analysis and word research measure about KEFIR — each figure with what it means.

Optimal play

Opening with KEFIR, a proven-optimal strategy averages 3.76 guesses — rank #8,690 of 14,855 legal openers. The best proven opener, TARSE, averages 3.55.

No guaranteed hard-mode solve In hard mode, no strategy that opens with KEFIR can guarantee a solve within six guesses.

Our six-turn simulation says 3.72 — at or below the proven-optimal 3.76 only 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) — not the site's working answer pool.
