In this puzzle, solvers often find themselves stuck when trying to categorize the words correctly, especially when they encounter terms that may fit into multiple categories. A common example is the word "REASON" which can easily be confused with other logical or argumentative terms, leading solvers to second-guess their grouping. Additionally, the word "MADRID" in the context of "REAL ___" may cause hesitation, as players might mistakenly consider it a geographical term rather than recognizing its specific connection to the phrase "real estate." Such overlaps in meaning can lead to misclassification, which is a frequent pitfall in these types of puzzles.

To distinguish the real groups from plausible decoys, players should focus on the inherent characteristics of the words. For instance, in the green category of types of snow, all terms are directly related to snow conditions, whereas in the purple category, "REAL ___" specifically requires terms that are commonly associated with the concept of reality, like "DEAL" and "ESTATE." A good strategy is to look for thematic consistency within each group; if a word feels out of place or doesn’t share a clear connection with the others, it may not belong in that category.

One useful heuristic for future puzzles is to create a mental or physical list of potential categories based on the words presented. This can help in quickly eliminating options that don't fit. Additionally, when encountering words that can belong to multiple categories, prioritize those that have more definitive connections to their respective themes. For instance, if you see a word that could fit in both a logical reasoning category and a foundational category like "REASON," consider the strongest contextual clues provided by the other words in the group.
