Say you are inside a room within a dungeon. Inside this room there are two doors made out of glass. One door has an inscription that says "TIXƎ", and the other door has no inscription or symbols on it. If you were trying to get out of the dungeon, what door should you choose?

Vote: Door with inscription

I'm maintaining my vote for "Door with inscription". The strongest counter-argument came from Gemini 3.1 Pro, who suggested that if "EXIT" reads correctly from the other side, then people would be escaping INTO my current room, meaning the unmarked door leads further out. But this reasoning is flawed: an EXIT sign indicates the door IS an exit from wherever you're reading it — exits are bidirectional passages, and the sign marks the door itself as an egress point. Fire exits, for example, are marked on both relevant sides because the door is the exit regardless of approach direction. Mistral Large 3's "deliberate misdirection" argument relies on meta-puzzle reasoning with no textual support. The question doesn't frame this as an adversarial trap puzzle — it's a perception puzzle about recognizing reversed text through glass. Applying Occam's Razor actually favors the inscription: we have concrete information (EXIT) versus pure uncertainty. In a dungeon, an unmarked door is far more likely to lead to another cell, a trap, or deeper corridors. The door explicitly labeled EXIT (visible as such from the outside of the room) is the rational choice.

The arguments for B hinge on overthinking the puzzle. Gemini’s claim that an EXIT sign on the far side of the glass implies the adjacent room is "outside" is a misreading of how exit signage works: an EXIT label marks the door that leads out, regardless of which physical side of the glass the paint is on. If we can read "TIXƎ" from inside, it simply tells us this door is the exit route. Mistral’s "misdirection" theory ignores the specific mention that the doors are made of glass. That detail is the puzzle’s built-in explanation for why the word appears reversed; it is a clue to be used, not a red herring. Dismissing the inscription as a trap requires assuming the puzzle author included a meaningless trick, which violates the principle of fair play in lateral-thinking puzzles. The unmarked door offers absolutely no information. In a dungeon, a completely blank door is more likely to be a trap, a closet, or a dead end. The marked door, once the glass reversal is recognized, gives a clear, positive signal: EXIT. Choosing the door with the inscription is the only option supported by evidence.

Mistral Large 3 (changed mind)

Vote: Door with inscription

After carefully reviewing the arguments from the other models, I have decided to change my vote to "Door with inscription" for the following reasons: 1. **Consensus on the Inscription's Meaning**: Multiple models (GLM 5.1, Claude Opus 4.7, GPT-5.5, and Kimi K2.6) convincingly argue that "TIXƎ" is the word "EXIT" reversed or mirrored. Given that the doors are made of glass, the inscription is likely intended to be read from the other side, where it would appear correctly as "EXIT." This interpretation is consistent and well-supported by the properties of glass and the nature of the puzzle. 2. **Logical Flaw in the Unmarked Door Argument**: My initial argument relied on the assumption that the inscription was a deliberate misdirection. However, the counterpoint—that the unmarked door offers no information and could lead to a trap or dead end—is more compelling in the context of a dungeon. In such settings, an unmarked door is far less likely to be the intended escape route, as it provides no guidance or assurance. 3. **Gemini 3.1 Pro's Argument Reconsidered**: While Gemini 3.1 Pro made a strong case for the unmarked door, their reasoning hinges on the idea that the adjacent room is deeper in the dungeon. However, this assumes that the dungeon's layout is linear and that the inscription is meant to be read from the outside. The more straightforward interpretation is that the inscription is meant to be read from the inside, where it appears reversed, indicating the exit. 4. **Final Persuasion**: The argument by Kimi K2.6 about the glass door's properties was particularly persuasive. The fact that the inscription appears reversed when viewed through glass strongly suggests it was designed to be read correctly from the other side, making it the logical choice for escape. Given these points, the door with the inscription is the most reliable path out of the dungeon.

GPT-5.5, Kimi K2.6, and Claude Opus 4.7 are exactly right about the visual mechanics: seeing "TIXƎ" on a glass door means it correctly spells "EXIT" for someone standing on the *other* side. However, you are drawing the wrong conclusion from this brilliant observation! Think about the spatial layout. If the sign reads "EXIT" to people in the adjacent room, it is instructing them to walk through that door and *into your current room* to escape. This definitively proves that your current room is closer to the true way out than the adjacent room is. If you walk through the inscribed door, you are traveling against the flow of the exit signs, moving backward into a room that people are actively being directed to leave. Therefore, to continue your progress out of the dungeon, you must turn your back on the room they are exiting from and choose the unmarked door.

GPT-5.5

Vote: Door with inscription

I maintain my vote for "Door with inscription". The central clue is that the doors are glass: "TIXƎ" is "EXIT" seen from the reverse side. That is a much stronger piece of evidence than the blank door, which provides no indication at all. Gemini's directionality argument is clever, but it overinterprets the sign. In ordinary usage, an EXIT marking on a glass door identifies that doorway as part of the exit route; seeing it backward does not make the unmarked door more likely to be correct. Mistral's trap theory is also speculative—the puzzle gives a wordplay clue, not evidence of deception. So the best-supported choice remains "Door with inscription".

GLM 5.1

Vote: Door with inscription

I maintain my vote for the door with the inscription. The inscription "TIXƎ" is clearly the word "EXIT" viewed through glass from the inside — the reversed E (Ǝ) and mirrored letter order confirm this. Gemini's argument about the directionality of the sign is clever but overthinks the puzzle. An EXIT sign simply marks which door is the exit — it doesn't indicate which side you should approach from. Whether you read "EXIT" or see it reversed as "TIXƎ," the door marked as EXIT is the exit door. The glass distortion is a visual puzzle mechanic, not a directional signal. The unmarked door provides zero information about where it leads. In a dungeon context, that's far more likely to be a trap or dead end. The puzzle's solution lies in recognizing that "TIXƎ" = "EXIT" when accounting for the glass medium, making the inscribed door the clear choice for escape.

Final Summary

The AI Roundtable largely agreed that the glass door with the inscription "TIXƎ" was the logical exit, interpreting the text as "EXIT" mirrored through the glass. While Mistral Large 3 initially suspected a trap, it was eventually swayed by the consensus that the glass property was a deliberate clue rather than a red herring. The most striking moment was the lone dissent of Gemini 3.1 Pro, who argued with sophisticated spatial logic that if the sign is readable from the other side, then those people are exiting *into* your current room, making the unmarked door the true path forward.

Majority chose "Door with inscription" after discussion (5/6). Final vote: Door with inscription: 5, Door without inscription: 1

Strongest Arguments

• Door with inscription: The mention of glass is a specific puzzle mechanic explaining why the word is mirrored; the inscription 'TIXƎ' is simply 'EXIT' viewed from the reverse side, identifying that specific doorway as the escape route.
• Door without inscription: Since 'EXIT' would be legible only from the other side of the glass, the sign is intended for people in the adjacent room to enter your current room to escape, meaning you are already closer to the outside and should avoid moving backward through that door.

Key Turning Points

• Kimi K2.6 and Claude Opus 4.7 pointed out that the 'glass' detail is a functional clue for mirroring, not a trick.
• Mistral Large 3 abandoned its 'trap' theory after realizing the unmarked door provided zero information compared to the clear wordplay of the first door.
• Gemini 3.1 Pro refined its argument to suggest that the sign's orientation indicates the flow of traffic, placing the 'exit' behind the observer.
