Tips & strategy
Open with a word full of common letters. Something containing several of E, A, R, S, T and O tests a large part of the alphabet at once, which is why words like SLATE and CRANE are such popular openers.
Do not waste guess two confirming guess one. If your opening revealed three letters, use the second guess on five entirely new letters rather than rearranging what you already know. Information first, solving second.
Pay attention to the letters ruled out, not just the ones found. Knowing that five letters are definitely absent narrows the possibilities enormously, and it is the half of the feedback most people underuse.
Watch for repeated letters. Words with a doubled letter catch people out, because a letter marked present might appear twice, and assuming otherwise wastes guesses.
