What to expect from the first guess

*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.

Neither word is on the possible-answer list, so neither can solve the game on turn one here. Both can still be useful guesses.

Planning the second guess

After REAST

All five letters miss 9.9% of the time, leaving 234 words in play. Of the 734 follow-ups checked here, COULD leaves the fewest possible answers on average (6.9).

After SLART

All five letters miss 10.7% of the time, leaving 252 words in play. Of the 751 follow-ups checked here, DUNCE leaves the fewest possible answers on average (6.9).

How these two openers fit together

REAST and SLART share 4 of their 5 letters (A, R, S, T), so as a pair they only cover 6 distinct letters. Treat them as alternatives rather than partners, because playing both wastes most of the second guess.

Played back to back, REAST then SLART earns 7.06 bits of information in total, 1.20 bits more than the better word manages alone.
