SLATE leads in the previous complete six-turn benchmark

These game-length figures come from the previous complete opener benchmark against its 2,354-answer snapshot, ranked by average guesses among games solved within six. Its answer snapshot and continuation policy are separate from today's solver recommendations.

The same solver played from both openers. SLATE has the lower average in games solved within six: 3.55 guesses to 3.57 for STALE.

Looking only at the opening row, SLATE has higher entropy (5.86 bits versus 5.74). That describes first-guess separation, not the full solve on its own.

Against 1,859 past Wordle answers, SLATE left the smaller first-guess group on 34% of dates; STALE did so on 16%, with the rest tied.

*Treating every word in the possible-answer list as equally likely.

Both openers come back completely gray at almost the same rate, so the difference between them lies in how much their hits actually tell you.

Planning the second guess

After SLATE

All five letters miss 9.7% of the time, leaving 228 words in play. Of the 728 follow-ups checked here, IRONY leaves the fewest possible answers on average (6.9).

After STALE

All five letters miss 9.7% of the time, leaving 228 words in play. Of the 728 follow-ups checked here, IRONY leaves the fewest possible answers on average (6.9).

How these two openers fit together

SLATE and STALE share 5 of their 5 letters (A, E, L, S, T), so as a pair they only cover 5 distinct letters. Treat them as alternatives rather than partners, because playing both wastes most of the second guess.

Played back to back, SLATE then STALE earns 6.07 bits of information in total, 0.21 bits more than the better word manages alone.
