Wordle #1,639, measured
This section compares SWING'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
This score is a percentile, not an opinion. Under the site's fixed solver settings, SWING measured harder for the solver than about 28% of all 1,952 recorded answers to date. Its rating is easier for the solver. CRANE, SLATE and ADIEU leave about 73.7 possible answers; it has a 4-word S_ING family.
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
ARISE left the fewest candidates: its first-guess feedback left 30 of the 2,384 words in the site's working answer pool. At the other end, AUDIO left 275 candidates, about 9 times as many. TRACE came back all gray. None of its letters appear in SWING. The vowel-heavy probes ADIEU and AUDIO revealed comparatively little here. Vowel coverage helps only when the answer's vowels are still in doubt.
| Opener | First-guess feedback | Answers still possible |
|---|---|---|
| ARISE | ARISE | 30 |
| RAISE | RAISE | 30 |
| CRANE | CRANE | 58 |
| SALET | SALET | 58 |
| SLATE | SLATE | 58 |
| STARE | STARE | 70 |
| TARSE | TARSE | 88 |
| ADIEU | ADIEU | 105 |
| TRACE | TRACE | 256 |
| AUDIO | AUDIO | 275 |
“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.
