In this puzzle, solvers often get stuck on distinguishing between the groups due to the presence of plausible decoys that can easily confuse them. For instance, the words "BUN" and "ROLL" might lead some players to associate them with the concept of food or bakery items, but they actually belong to the category of deli bread options. Similarly, the terms "KISSER" and "TRAP" can mislead solvers into thinking they fit into a different category, as they have more abstract meanings compared to the other slang terms for mouth. This confusion arises because players may not be fully aware of the specific contexts these words are commonly used in, leading to incorrect groupings.

To effectively distinguish the real groups from the decoys, solvers should focus on the thematic consistency of the words. For example, all options in the yellow category relate directly to types of bread used in deli sandwiches, which is a clear and specific theme. In contrast, the green category is centered around slang terms for mouth, which can be more abstract but still follows a clear linguistic theme. By identifying the primary context or theme of each word, players can better categorize them and avoid common pitfalls.

One useful heuristic for future puzzles is to look for shared characteristics that define each group. For example, identifying the function or common usage of the words (like food-related terms or slang) can help in grouping them correctly. Additionally, players should keep an eye out for words that may seem to fit multiple categories but ultimately have a stronger association with one theme. By practicing this method of thematic identification and context awareness, solvers can enhance their grouping skills in future puzzles.
