NAIEO vs SLART
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 3.67 for NAIEO.
Looking only at the opening row, SLART has higher entropy (5.63 bits versus 5.39). That describes first-guess separation, not the full solve on its own.
One thing NAIEO does better is damage control. Its worst feedback pattern leaves 189 possible answers, while SLART can be left staring at 252.
