See which word leaves you with the easier game.

Tied 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 six-turn results are effectively tied: when the same solver plays from each word, ROAST averages 3.46 guesses and SLART averages 3.46 in games solved within six.

Looking only at the opening row, ROAST has higher entropy (5.65 bits versus 5.63). That describes first-guess separation, not the full solve on its own.

Against 1,858 past Wordle answers, SLART left the smaller first-guess group on 54% of dates; ROAST did so on 44%, with the rest tied.

What to expect from the first guess

OutcomeROASTSLART
First-turn solve* 0.04% 0%
At least one green 39.6% 40.8%

*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.

SLART 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 ROAST

All five letters miss 11.5% of the time, leaving 270 words in play. Of the 770 follow-ups checked here, CLINE leaves the fewest possible answers on average (5.8).

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

ROAST 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, ROAST then SLART earns 6.86 bits of information in total, 1.21 bits more than the better word manages alone.
