Daily routine
Use this routine before and after each puzzle to reduce random guesses and learn from difficult categories.
Do not start by tapping the first familiar pair. Read all 16 words once, then read them again in a different order. The second pass often reveals a cleaner category because your brain has already warmed up to the vocabulary.
During this scan, mentally mark words that have more than one meaning. These words are common decoys. A word like "pitch" can be a throw, a sales presentation, a field, or a sound quality. Flexible words deserve extra caution.
Before submitting anything, name at least two possible groups. This prevents tunnel vision. If you only see one theory, every nearby word starts to look like proof. A second theory gives you a comparison point and makes false matches easier to spot.
The theories do not need to be perfect. They only need labels: "coffee drinks," "things with keys," "words after moon," or "card terms." Clear labels protect you from vague guesses.
Choose the group where all four words fit the same label with the least explanation. If one word needs a story, leave it out. The first solved group is valuable because it removes four distractions and makes the remaining board easier.
If you get one away, pause. Do not immediately swap words at random. Ask which word is weakest, then check whether that word belongs to another possible group.
After finishing, look at the group that gave you the most trouble. Was the clue literal, phrase-based, sound-based, spelling-based, or based on a second meaning? Naming the type is more useful than simply remembering the answer.
This short review is how players improve. Tomorrow's board will have different words, but the same pattern types return. A player who recognizes pattern types has a major advantage over a player who only remembers old answers.
