Why this Betweenle solver works
Betweenle is really a range-narrowing puzzle. Every guess tells you whether the answer is alphabetically above or below your word, and the percentages reveal how close the answer is to each bound. This solver combines both pieces of information to make smarter guesses than a plain middle-word strategy.
When the remaining range gets small, the page also shows the possible words directly so you can finish the puzzle quickly without guesswork.
