A first-person puzzle game where you flip between parallel dimensions to manipulate physics and rescue your kidnapped uncle from his own ridiculous mansion.

Quantum Conundrum is a first-person physics puzzler developed by Airtight Games and published by Square Enix. You play as a kid dropped off at your eccentric uncle's massive mansion, only to find him missing and the place locked down. Your only tool is the Interdimensional Flux Shifter, a glove that lets you toggle between four alternate dimensions on the fly: Fluffy (objects become light), Heavy (objects become dense and crush things), Slow Motion, and Reverse Gravity. Each dimension changes how every object in a room behaves, and most puzzles require chaining multiple shifts together in sequence to move platforms, redirect laser beams, or fling safes across gaps. From a mechanics standpoint, this is a tight, well-scoped puzzle game. The dimensional shifting is the single core system, and the designers squeeze a lot of variety out of it without bloating the runtime. A typical puzzle asks you to make a couch light enough to carry, switch to Heavy mid-throw so it smashes a button, then pop into Slow Motion to sprint across before a door closes. That loop stays satisfying for most of the roughly five-to-six hour campaign. The difficulty curve is mostly fair, though a handful of late-game sections lean into precise timing in ways that feel more like a platformer than a puzzler, which will frustrate players who came for logic over reflexes. Where Quantum Conundrum stumbles is in the execution of its personality. The uncle's voice-over narration is clearly angling for the same comedic warmth Portal achieved with GLaDOS, but the writing lands inconsistently. Some jokes earn a smile; others repeat themselves or overstay their welcome. The mansion aesthetic is charming in screenshots but gets visually repetitive across its three main wings. There is no mod support to speak of, no replay hooks, and no difficulty settings, so the experience is largely linear and self-contained. For a strategy-minded player, that means you get one clean run through the design, absorb what the developers intended, and you are done. That said, the core design philosophy here is genuinely smart. Each room is essentially a small constraint-satisfaction problem: you have four tools, a fixed set of objects, and one correct order of operations. If you enjoy breaking a system down to its variables and solving for the optimal sequence, there is real satisfaction in Quantum Conundrum even if it never reaches the depth that a longer puzzle game might offer. It is not a grand-strategy experience by any means, but the same analytical instinct that helps you optimize a build order will make these puzzles click quickly. New players to the genre will find the early rooms function as a solid, respectful tutorial that introduces one mechanic at a time before combining them. Bottom line: this is a well-built, compact puzzle experience with a clever central mechanic that the developers use responsibly. It is not a long game, it has no community ecosystem around it, and the humor misses as often as it lands. But if you want a few evenings of clean, physics-based puzzle solving with a low barrier to entry, Quantum Conundrum delivers exactly what it promises and not much more. Diego, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
