I review thinking-puzzle games on Steam from a designer's perspective. Putting meta-puzzle lineage, Undo design, and learning-curve craft into words — that's the core of my criticism. Observational, restrained tone.

Closing Into One Screen — The Density a One-Screen Puzzle Builds
Sokoban, Baba Is You, Snakebird, Patrick's Parabox — the strongest thinking puzzles keep their whole board on one screen. A designer's look at why simultaneous visibility deepens thought, and when breaking the frame is worth its cost.
The Grammar of Zachtronics — Translating Programming into Puzzle
SpaceChem, TIS-100, Shenzhen I/O, Opus Magnum, Exapunks. A maker's-eye reading of the programming-puzzle grammar Zach Barth honed from 2011 to 2022, along three axes: the command queue as a verb, optimization design that abandons the single solution, and the ladder of abstraction.
Narrative Puzzles and Storyless Puzzles — Lorelei vs Stephen's Sausage Roll

One button reshapes the entire experience. Sokoban's restart, Braid's rewind, Baba Is You's unlimited Undo. A look at the dividing line between designs that forgive trials and designs that punish them.

Quantum Conundrum
A first-person physics puzzler in which a boy searches a deranged mansion for his missing inventor uncle, armed with the Interdimensional Shift Device. Swap between four dimensions — Fluffy makes heavy things weightless, Reverse Gravity flips the pull, Slow slows time — and bend boxes and physics to clear each room. Built by Portal's lead designer Kim Swift (as reported) and published by Square Enix.
The Swapper
A 2D puzzle-platformer where a gun lets you spawn up to four clones and swap your consciousness between them as you descend the derelict space station Theseus. Red and blue lights bar cloning and swapping in a tight grammar while a lonely clay-modeled world quietly asks what the self is — from Facepalm Games.
Braid, Anniversary Edition
A single-player puzzle-platformer where you rewind, pause and bend the rules of time, world by world, to clear 2D hazards and assemble jigsaw pieces. Thekla's remaster of the 2008 indie classic — fully repainted, with hours of developer commentary.
Toki Tori 2+
A puzzle adventure across an open forest island where your only moves are whistle and stomp. You never unlock new abilities — only knowledge of how each creature behaves — in Two Tribes' 'Metroidbrainia.'
Void Stranger
A 2D Sokoban puzzler in which you lift a floor tile with a rod and set it down elsewhere, descending a forgotten labyrinth past traps and foes. From a handful of verbs grow bottomless puzzles and a hidden story — made by System Erasure.
Storyteller
A puzzle about arranging characters and scenes across comic panels to satisfy a given story title — love, revenge, jealousy — making each prompt come true as a few-panel tale. A compact narrative puzzle by Daniel Benmergui.
FEZ
An exploration platformer where you rotate a 2D world in 90-degree turns, shifting how the plane reads to connect platforms. Collect cube fragments while wandering a crumbling world — Polytron Corporation's signature take on rotation.
The Spectrum Retreat
A first-person puzzler set in the art-deco Penrose Hotel: you pull a colour out of one wall, carry it, and hand it to a matching barrier to open the way. Steam sits at 'Mostly Positive,' 76% of 223 (snapshot 2026-06-16); opinion splits over its double structure of puzzle and story.
ChromaGun
A first-person puzzle where you fire colored paint at walls and roving droids, mixing primary colors to lure each droid onto a matching panel — a Portal-style test-chamber game built on a single verb: painting.
Cosmic Express
A route-drawing puzzle: lay down train tracks to pick up and drop off cute alien passengers in the right order, fitting one winding path into a tight grid.
Filament
A puzzle game where you steer a small probe to wrap a single trailing cable around pillars, solving each room of an abandoned spaceship with one unbroken, non-crossing line.
The Turing Test
A first-person sci-fi puzzle on a moon of Jupiter: redirect energy orbs between sockets to open doors and cross a series of test chambers, wrapped in a story about machine and human judgment.
Taiji
A grid-based logic puzzle in the lineage of The Witness: toggle tiles on panels by deducing unwritten rules through pure observation, as you roam a quiet open world.
Islands of Insight
A sprawling open-world puzzle game with thousands of hand-crafted puzzles — line-drawing, observation, logic — scattered across a fantasy realm to solve at your own pace.
The Pedestrian
A 2D puzzle-platformer where you rearrange and wire together public signs, building a path through the signage for a little stick figure to cross a living city.
The Case of the Golden Idol
A deduction game: examine frozen crime-scene tableaus, gather words from the evidence, and fill in the blanks to reconstruct each murder across an 18th-century mystery.
Viewfinder
A first-person perspective puzzle where the photographs you place into the world become real 3D space, letting you reshape the environment to find a path through.
Maquette

Superliminal
A first-person puzzle where perspective alone decides how big things are.
Chants of Sennaar
Climbing a Babel-like tower, you decipher the unknown logographic language of each floor's people from pictures and gestures. A game of observation and inference.
Snakebird
