SLART vs UNIOS
See which word leaves you with the easier game.
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. SLART has the lower average in games solved within six: 3.55 guesses to 3.68 for UNIOS.
Looking only at the opening row, SLART has higher entropy (5.63 bits versus 4.71). That describes first-guess separation, not the full solve on its own.

*Treating every word in the possible-answer list as equally likely.
A fully gray row is rarer with SLART: it happens 10.7% of the time, against 18.5% for UNIOS.
Neither word is on the possible-answer list, so neither can solve the game on turn one here. Both can still be useful guesses.
