One key heuristic for solvers is to categorize words based on their primary meanings rather than secondary associations. This approach helps eliminate confusion when words have multiple interpretations. For instance, recognizing that 'DINE' and 'FEAST' are directly linked to meals allows players to confidently group them without getting sidetracked by other potential themes. Another useful strategy is to look for linguistic patterns, such as identifying foreign language components or specific grammatical functions, as seen with the Spanish words in the blue group. By applying these strategies consistently, players can enhance their problem-solving skills in future puzzles.
