Compare Molecule - a chemical challenge prices across trusted key stores and find the best deal. Developed by a.mighty.dish. Published by a.mighty.dish. Released on 3/2/2018. Available on PC. Genres: Indie.

A tiny Sokoban-style puzzler that wraps genuine chemistry trivia around some surprisingly mean atom-pushing logic. Short, handcrafted, and brutally honest about its difficulty.

I have a soft spot for the kind of game that fits on a USB stick and still manages to make me feel quietly stupid. Molecule - a chemical challenge is exactly that. The core mechanic lifts cleanly from Sokoban: you push atoms around a grid, connecting them into a target molecular structure using the fewest possible moves. Spin plates rotate atom clusters, triggers toggle barriers, and the board layouts get genuinely mean as the 40 levels progress. Each of those levels corresponds to one real molecule, from simple salts up to more complex organic structures, and the game drops a small science fact on you when you finish one. It is a modest loop, but it is put together with quiet intention. The developer, a solo outfit called a.mighty.dish, comes from a visual effects background rather than a games industry one, and that origin story shows in two directions at once. The retro-inspired pixel presentation is clean and legible, with a spartan aesthetic that keeps your eye on the puzzle geometry rather than decorative noise. On the other hand, the settings menu offers exactly two audio toggles and no frame-rate cap, which has caused some players' hardware to spin up unnecessarily. The UI is bare-bones in a way that feels less like a design choice and more like a first release. There is no dedicated exit button; Escape brings a confirmation dialog. You work with what you have. The difficulty is the main story here. The game makes no apology for punishing play, and the global step-count leaderboard per puzzle adds a quiet competitive pressure that will interest efficiency-minded solvers long after the story solution is found. Beating a world record on a molecule like CINO3 with 20 moves is the kind of small, private triumph this game traffics in. That said, a reported bug where atom pieces enter a broken collision state and can pass through each other or vanish on contact is a real concern on trickier puzzles, and the developer's post-launch patch history is sparse. If you hit it mid-solve you will lose progress in a way that stings. Who is this for, honestly? Puzzle fans who like their logic games chemical-themed and structurally tight, and who do not need ambiance or narrative scaffolding to stay engaged. It is closer in spirit to classic Sokoban shareware than to something like SpaceChem, which layers programming complexity on top of molecule building. This one keeps the ask simple: shortest path, correct shape, move on. If you're a completionist chasing all 40 Steam achievements, there is a full solution guide in the community hub. If you want to earn them blind, budget a few focused evenings and accept that one or two molecules will sit in your head for days before the path clicks. Kai, 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.
