Wordle #643, measured

This section compares GROUT's solver-difficulty percentile, first-guess results for ten familiar openers, and opt-in player reports. Each number identifies its dataset.

Solver difficulty, as a percentile

40/100

This score is a percentile, not an opinion. Under the site's fixed solver settings, GROUT measured harder for the solver than about 40% of all 1,952 recorded answers to date. Its rating is middle of the pack. CRANE, SLATE and ADIEU leave a large group.

Solver pressure ranks the answer within the pool; it does not measure player performance. The opener table compares first-guess results, and the contributed ratings report player results.

CRANE, SLATE and ADIEU benchmark

TRACE left the fewest candidates: its first-guess feedback left 15 of the 2,384 words in the site's working answer pool. At the other end, ADIEU left 195 candidates, about 13 times as many. The vowel-heavy probes ADIEU and AUDIO revealed comparatively little here. Vowel coverage helps only when the answer's vowels are still in doubt.

“Answers still possible” counts the words in the site's 2,384-word working answer pool whose feedback would match that opener exactly. This is pattern arithmetic, not a simulation. A smaller number means the opener left fewer possible answers after the first guess. It does not describe later turns.
