CARLE leads in the current bounded six-turn policy

Both words are in the current screen of 182 openers, tested against 2,358 answers. Exact misses rank first; average guesses among wins break ties.

The same solver played from both openers. CARLE has the lower average in games solved within six: 3.46 guesses to 3.48 for REACT.

Looking only at the opening row, CARLE has higher entropy (5.76 bits versus 5.69). That describes first-guess separation, not the full solve on its own.

What to expect from the first guess

OutcomeCARLEREACT
First-turn solve* 0% 0.04%
At least one green 43.9% 37.2%

*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.

CARLE is not on the possible-answer list, so it cannot solve the game on turn one here. It can still be a useful guess.

Planning the second guess

After CARLE

All five letters miss 10.9% of the time, leaving 258 words in play. Of the 758 follow-ups checked here, SNOUT leaves the fewest possible answers on average (6.2).

After REACT

All five letters miss 10.7% of the time, leaving 253 words in play. Of the 753 follow-ups checked here, SOILY leaves the fewest possible answers on average (7.1).

How these two openers fit together

CARLE and REACT share 4 of their 5 letters (A, C, E, R), 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, CARLE then REACT earns 7.39 bits of information in total, 1.63 bits more than the better word manages alone.
