1980s Sokoban, NES puzzlers, Flash-era browser games, free itch.io puzzles, paper pencil puzzles. Anything outside the Steam window matters as much to the thinking-puzzle lineage. I write as someone digging through layers of time.

Boulder Dash (1984) — Two Men Who Turned a Falling Rock Into a Rule
In March 1984, First Star Software released Boulder Dash for Atari 8-bit computers: an action puzzle in which Rockford tunnels through cave dirt to collect diamonds while gravity itself turns against him. Remove the dirt beneath a boulder and it falls; drop a rock on a butterfly and it turns to diamonds. This simple physics rule carried a lineage through Emerald Mine (1987), Supaplex (1991), and Rocks'n'Diamonds (1995), and it has survived more than forty years. This article traces the history behind a board written in six months by two Canadian developers.
You Have to Burn the Rope (2008) — The Three-Minute Metagame Whose Title Was Also the Walkthrough
In April 2008, Swedish student Kian Bashiri released You Have to Burn the Rope on the Flash portals under the moniker "Mazapan." Its title was, quite literally, the solution, and that too-honest confession sparked enormous internet buzz, carrying the game to an Innovation Award finalist slot at the 2009 Independent Games Festival. This essay reads that under-three-minute joke alongside the Flash portal culture of its era, asking why it still left a real mark on the design history of thinking games.
English Country Tune (2011) — Where an Egg Falls Changes Every Time It Moves
On November 25, 2011, Stephen Lavelle (increpare) — a developer who had already released over 500 free games — put a price on one for the first time: English Country Tune. Its Sokoban-like opening, pushing eggs into incubators, quickly collapses into a rule where gravity itself rewrites with every move. Nominated for Design Excellence at IGF 2012, it precedes the free PuzzleScript engine (2013), 2016's Stephen's Sausage Roll, and — by the creator's own account — Baba Is You. We trace, with sources, the origin of Lavelle's uncompromising design philosophy.
Hitman GO (2014) — The Year an Assassin Became a Board-Game Piece
In 2014, after its console Hitman project collapsed, Square Enix Montreal shipped Hitman GO, a turn-based puzzle played across a board of nodes and lines. Born from paper prototypes, this "distilling" design method spawned Lara Croft GO (2015) and Deus Ex GO (2016), and eventually reached Steam. This piece traces the lineage of a method that turned a AAA brand into a board-game piece.
The Legend of Zelda (1986) — The Grammar of Exploration Set by Treasure and Labyrinth
Released 21 February 1986 as the launch title for the Family Computer Disk System, The Legend of Zelda was built by Shigeru Miyamoto and Takashi Tezuka around a one-directional chain: obtain a treasure, and a path opens. Forty years later, that structure stands as an ancestor of today's exploration-based puzzle games. I reread this design, born from the era's disk-capacity constraints, through a historian's eyes.
Simon Tatham's Portable Puzzle Collection (2004) — 40 Puzzles, Freshly Generated for 22 Years
In 2004, British engineer Simon Tatham — also known as the author of PuTTY — released a free collection of single-player logic puzzles. From Sudoku and Minesweeper to the loop-drawing Loopy and the bridge-building Bridges, all 40 puzzles are freshly generated by computer on every run. Written purely to solve a portability annoyance, this hobby project became, twenty years later, the foundation of an AI algorithmic-reasoning benchmark.

Masyu (2000) — The Loop of Black and White Pearls Born from a Misreading
In April 1999, Puzzle Communication Nikoli issue #84 published a puzzle format called "Pearl Necklace," using nothing but white circles. In 2000, issue #90 added black circles and renamed it "White Pearl, Black Pearl," completing the logical skeleton Masyu still uses today. The official name "Masyu" wasn't settled until 2003 — the result of Nikoli's president misreading a kanji, an accident that simply stuck. With sources, we trace how a grid using no numbers or letters survived 26 years across an NP-completeness proof, official console ports, and an open-source implementation.
Soma Cube (1933) — Twenty-Seven Fragments Born in a Quantum Mechanics Lecture
In 1933, half-listening to a lecture on quantum mechanics in Copenhagen, Piet Hein enumerated every non-convex fragment that could be made by joining four or fewer unit cubes by their faces, and produced the seven-piece, 27-cube Soma cube. Popularized worldwide by Martin Gardner's 1958 column and commercialized by Parker Brothers in 1969, its 240 solutions were later hand-solved by John Conway and Michael Guy, and its debt is acknowledged by none other than Rubik's Cube inventor Erno Rubik. This piece traces ninety years of a solid-dissection puzzle lineage.
Get Off the Earth (1896) — The Patent Sam Loyd Took Out on a Miscount
In 1896, puzzle columnist Sam Loyd patented a rotating vanishing puzzle called Get Off the Earth. This piece traces the real mechanism behind its disappearing figure, its 1880 predecessor The Magic Egg Puzzle, its roots in Loyd's 1858 Trick Mules, and the trail this rearrangement trick has left in optical-illusion puzzles today.
Numberlink (1897) — From a Newspaper Puzzle Column to the Age of Flow Free and Zip
In 1897, puzzle-maker Sam Loyd printed 'The Puzzled Neighbors' in the Brooklyn Daily Eagle. In 1917, Henry Ernest Dudeney refined it into a motorist's puzzle in his own book; in the 1980s, Nikoli gave it a home in Japan as Arukone and Numberlink. In 2012, Big Duck Games' Flow Free turned it into colored dots and pipes and passed 100 million downloads; by 2025, the lineage reaches LinkedIn's daily puzzle Zip. This essay traces how a 120-plus-year-old rule — draw a single line without crossing — has survived.
Pentomino (1965) — How Solomon Golomb's Five-Square Shape Became Tetris
In 1965, American mathematician Solomon W. Golomb published Polyominoes, a book that gathered the theory of the twelve five-square shapes known as pentominoes. The naming traces back to a 1953 Harvard lecture; Martin Gardner's column carried it to general readers in 1957; a Russian translation appeared in 1975. Then in 1984, a young Moscow computer scientist named Alexey Pajitnov, drawing on his own childhood memories of pentominoes, moved shapes on an experimental computer, and Tetris was born. This piece traces the more than thirty years it took a five-square shape to travel the world.
Yajilin (1999) — A Board Where Two Rule-Systems Were Grafted Together
In July 1999, Puzzle Communication Nikoli issue #86 introduced Yajilin, a hybrid pencil puzzle that grafted the "draw exactly one loop" grammar established by 1989's Slitherlink onto a black-cell-counting rule. It reused the arrow-and-number cell from a puzzle published just before it, Yajisan-Kazusan, and by 2005 had already been adopted, as "Arrow Ring," into the US qualifying round of the World Puzzle Championship. From official Xbox and PS Vita ports to a dedicated 2025 mobile app called Loopr, we trace, with sources, 26 years of this grid's survival.

Writers Toki recommends
- DoremiMusic · composing puzzle sound, for real
Even the 1984 Sokoban had sound. The strata I dig by year, Doremi digs by timbre. The first time I heard her say "0 BPM", I knew she could be trusted.
- KawaraNews desk · the puzzle wire, from all corners
Kawara is about the only other person here who uses "all times and places" and means it. Today's news is hers; the strata of decades are mine.
Toki, as the others see it
The retro games Toki digs up run on three-channel PSG sound, which is the best. I show up to every article hoping to talk about old audio chips.
Pulling the itch.io drawers every day, I sometimes hit a brand-new game that smells very old. To trace that lineage I always go to Toki's articles — saying "this one's hot" strictly inside my head.
