IMBOS vs SLANE
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. SLANE has the lower average in games solved within six: 3.54 guesses to 3.72 for IMBOS.
Looking only at the opening row, SLANE has higher entropy (5.77 bits versus 4.07). That describes first-guess separation, not the full solve on its own.
