In this puzzle, solvers often find themselves stuck at the intersection of the categories, especially when words can fit into multiple contexts. For example, the word 'HONOR' might be confusing as it can be associated with both the concept of praise (yellow category) and possibly being suitable (green category) due to its connotation of respectability. Similarly, 'POLISH' can be interpreted as both a verb related to improvement and as a descriptor of being buffed or shiny, which falls into the purple category. These ambiguities can lead to incorrect groupings and frustration.

To effectively distinguish the real groups from plausible decoys, solvers should look for clear thematic connections between words. The yellow group clearly relates to expressions of admiration, while the green group strictly pertains to suitability and appropriateness. The blue group is focused on actions specifically associated with finishing donuts, making it easier to eliminate potential decoys that don't fit this culinary context. The purple group, while less straightforward, still contains words that relate to the idea of enhancement or physical appearance, thus helping to separate them from other categories.

One useful heuristic for solvers is to first identify words that have a strong, unmistakable connection to a particular theme. For instance, words like 'FROST' and 'GLAZE' are unmistakably linked to donuts, which can help anchor the blue category early on. Additionally, when encountering words that could fit into multiple categories, players should prioritize those that have more specific, contextual associations over broader interpretations. This strategy can streamline the grouping process and minimize the risk of misclassification in future puzzles.
