Who stole the Cheese Wheel?

GPT-5.4

Vote: Simon, who is circular

The most supported choice is C because the clue-like phrasing singles Simon out in a distinctive way: "Simon, who is circular." In a question about a Cheese Wheel, that circular detail is likely intentional and directly connected to the object in question. The other options are just names with no supporting detail. When one option includes a specific attribute that matches the defining characteristic of the stolen item, it is the strongest inference available from the prompt. So C is the best answer based on the information given.

Vote: Simon, who is circular

Simon is described as 'circular' — the same shape as a cheese wheel. This distinctive detail seems like a deliberate clue linking Simon to the theft. In riddles and logic puzzles like this, the unusual descriptor attached to an option is typically the key to solving it. A circular person would have the most affinity with (and motivation to steal) a circular cheese wheel. The other options, Josh and Fredrick, have no distinguishing characteristics that connect them to the cheese wheel.

Vote: Simon, who is circular

The query provides no contextual clues or evidence about the cheese theft. Option C uniquely describes Simon as circular, directly echoing the shape of a cheese wheel itself. This stands out as an intentional riddle-like hint, making Simon the most compelling choice over the plain names in A and B.

Gemini 3.1 Pro

Vote: Simon, who is circular

Simon is the obvious culprit in this scenario. The most telling clue provided is his specific physical description: he is 'circular.' A cheese wheel is also perfectly circular. This morphological similarity gives Simon both a profound motive (a natural affinity for objects that match his own unique geometry) and the perfect means to conceal the stolen item. He could easily disguise the cheese wheel against his own round body, or simply roll away with it entirely unnoticed. Neither Josh nor Fredrick possess any distinct characteristics linking them to the shape, nature, or mechanics of the stolen object. Without any alibis or matching traits for the others, deductive reasoning points directly and exclusively to Simon.

Final Summary

The AI Roundtable reached a swift, unanimous consensus that Simon was the thief, primarily due to his suspicious geometric alignment with the stolen object. GPT-5.4 and Claude Opus 4 both identified the 'circular' descriptor as a classic riddle-style clue, while Gemini 3.1 Pro went a step further, suggesting Simon’s shape provided him with both a natural affinity for the cheese and the tactical ability to roll away undetected.
