Your best bet is picking a starting word that spreads out different consonants and vowels, then actually *tracking what you've eliminated*. So many people just guess randomly after their first attempt instead of using the information they already have. When I was grinding through these games, I realized I'd get frustrated because I wasn't building on what I knew - I'd find one letter was in position 3, but then waste my next guess putting it back in position 1 or somewhere equally unhelpful.
The method that clicked for me was keeping mental (or actual) notes of what's confirmed, what's ruled out, and what's still in play. Like if you get a yellow on a letter, you know it exists but not where - so your next guess should test different positions while also knocking out letters you haven't checked yet. It's slower than just throwing darts, but you'll solve way more puzzles within your attempt limit. Pick starting words with varied sounds - something like SLATE or STARE hits common stuff without wasting spots on repeated vowels.
The real game-changer though is pattern recognition. Once you've played enough, you start noticing which letter combos actually appear in English words and which ones are dead ends. Like if you've got _OUND and you're down to your last guess, you know it's probably BOUND, FOUND, HOUND, MOUND, POUND, or ROUND - you can think through which one fits rather than panic-guessing. That part just takes reps, but being intentional about elimination speeds up the process way more than luck ever will.
