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 3.47 for SLATE.

Looking only at the opening row, SLATE has higher entropy (5.86 bits versus 5.76). That describes first-guess separation, not the full solve on its own.

The past-answer results are close: across 1,858 puzzles, CARLE left the smaller first-guess group 50% of the time and SLATE did so 50% of the time, with the rest tied.

One thing SLATE does better is damage control. Its worst feedback pattern leaves 228 possible answers, while CARLE can be left staring at 258.

A fully gray row is rarer with SLATE: it happens 9.7% of the time, against 10.9% for CARLE.

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.
