All Reviews →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.
puzzlepuzzle-platformerfirst-personThe 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.
puzzlepuzzle-platformersci-fiBraid, 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.
puzzleplatformerlogicToki 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.'
puzzlemetroidvaniaVoid 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.
puzzlesokoban-likemeta-puzzleStoryteller
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.

Essays
All Essays →Soundtrack: Braid, Anniversary Edition — only the sounds that survive being reversed
The music of Braid was not composed. Jonathan Blow hired no composer; he licensed existing cello and harp pieces from Magnatune artists, under a single condition — that they stay beautiful when played backwards. A puzzle game that runs time in reverse, scored with music that doesn't break when reversed. For the Anniversary Edition, LIMBO's Martin Stig Andersen remixed seven tracks into electroacoustic shadows. Black coffee in hand, I, Doremi, take apart 'reversible music'.
Inside Stephen Lavelle's Philosophy — Making the Refusal to Explain Into the Work
"Nah I don't feel like it." That was how Stephen Lavelle (Increpare) answered a player who asked him to explain his puzzle design. The prolific maker of 500-plus freeware games, the author of the free engine PuzzleScript and of Stephen's Sausage Roll. I read his philosophy, obsessions, failures, dilemmas and influences using only words he himself wrote.
Puzzles Made to Show Off a System, Not to Stump You — Patrick Traynor on System-Centric Design in Patrick's Parabox (GDC 2024)
One article today: the official slides from Patrick Traynor's GDC 2024 talk, "System-Centric Puzzle Design in Patrick's Parabox." His premise is inverted: "the purpose of the system is not to make cool puzzles. The purpose of the puzzles is to showcase this cool system." So difficulty is tuned to communicate, not to challenge — puzzles simplified as much as possible while still conveying their idea. He covers smoothing the learning curve (insert, modify, delete, reorder, optionalize), ~15 full-game playtests recorded with narration, an idea-finding method of "find an interaction and force it," and a heuristic for a good puzzle system: how many puzzles you can make in it. 364 shipped puzzles, 600+ unused drafts. A 2024 talk, but worth reading now for how it reframes a core design assumption.
Li et al.: AutoBG, an AI that supports board game design end-to-end from ideation to finish — Fukai Reads
A paper (arXiv preprint) by Zizhen Li et al. on AutoBG, a board game design assistant that covers the whole workflow—ideation, rulebook generation, and individualized feedback—via Verifier-Gated Iteration that splits the generator from the critic; the critic, BG-Critic, is reported to outperform GPT-5.4 on diagnostic quality.
Soundtrack: The Talos Principle 2 — answering scale with a choir
A first-person puzzle in which you leave New Jerusalem, the city the robots built, and walk toward the colossal Megastructure on the horizon. Damjan Mravunac's music is written for orchestra, electronics, and choir, sounding the small time of solving a puzzle and the time of marveling at the size of the world at two different tempos. Black coffee in hand, I, Doremi, take apart why the biggest sound is reserved for the walking.
Where 'Solvable' and 'Fun' Diverge — PuzzleJAX Hands 500+ PuzzleScript Games to the Machines (arXiv, Aug 2025)
One article today: "PuzzleJAX: A Benchmark for Reasoning and Learning" (arXiv preprint, August 2025) by researchers at NYU, the University of Malta, the University of the Witwatersrand (South Africa), and Microsoft (Sam Earle, Graham Todd, Ahmed Khalifa, Julian Togelius and others). They reimplement PuzzleScript — Stephen Lavelle's (increpare) 2013 puzzle-authoring language — on the GPU and hand 500+ human-authored games to tree search, reinforcement learning, and large language models. Read as a designer, the core is one observation: 'solvable by a machine' and 'interesting to a human' are not the same thing. Tree search brute-forces simple games but stalls the moment they get richer; LLMs score 0% on most. The authors even note PuzzleScript's own creator hesitating to embed an auto-solver into the IDE, a caution about measuring difficulty by search.

Series
The Lineage of Meta-Puzzles
The lineage of games that turn rules themselves into something you operate on. How the idea of rewriting unfolded from Sokoban to Baba Is You.
Puzzles That Turn Looking into Play
A rare lineage where the act of looking is the progress. We read the design of observation puzzles through The Witness, Obra Dinn, and Lorelei.
The Design of Undo
A single rewind button reshapes the entire experience. Designs that forgive trials and designs that punish them.
Carving the Learning Curve
Where do you make the player stop, and where do you let them flow? From Baba's vertical wall to Cocoon's unbroken stream.
Recursive Puzzles
Boxes inside boxes, doors inside doors, worlds inside worlds. Games that translate recursion into puzzle mechanics.
Single-Verb Design
How deep can a single-verb game go? The lineage of Sokoban, Sausage Roll, and A Monster's Expedition.
