Most new ideas have decades-old prototypes. Each episode, Toki replays one retro puzzle in a modern setting, checking its original context and whether it is still worth playing now.
Episodes
- Ep. 15Puyo Puyo (1991) -- Inventing a New Verb Called "Chain"2026-07-11
Released simultaneously on MSX2 and the Family Computer Disk System on October 25, 1991, Puyo Puyo was conceived by Kazunari Yonemitsu and developed by Compile. Its 1992 arcade collaboration with Sega gave rise to a new verb: the chain (rensa). Even after Compile's collapse in 2003, this design survived -- through 2014's Puyo Puyo Tetris and its 2018 Steam release. I want to reread this one title as the starting point of competitive versus-puzzle design.
- Ep. 14Monument Valley (2014) — Walking Impossible Architecture in Mobile's Golden Hour2026-07-09
Released for iOS on April 3, 2014, Monument Valley was made by a six-person team spun out of a London design agency, who turned Escher's impossible figures into architecture you could walk. Arriving when freemium apps dominated the App Store, it sold millions by betting on the opposite: paid, short, and dense. I re-read it as both a record of mobile gaming's golden hour and a node in the lineage of perspective puzzles.
- Ep. 13Crimson Room (2004) — The Day a Red Room Made 'Escape' a World Word2026-07-06
On March 4, 2004, Japanese developer Toshimitsu Takagi released a small free Flash game. You wake in a crimson-walled room, gather keys and tools, and leave through a locked door — nothing more. Yet Crimson Room spread the 'escape the room' genre worldwide, gave Asia the genre name 'Takagism' after its author, and by its instigator's own testimony triggered the world's first real escape game in Kyoto, 2007. I read this red room as a rare junction where digital play flowed back into physical space.
- Ep. 12Pipe Mania (1989) — Betting the Route Before the Flow Arrives2026-07-05
In June 1989, Britain's The Assembly Line released Pipe Mania for the Amiga. In North America Lucasfilm Games distributed it as Pipe Dream, and in Japan Video System's arcade version was carried by Namco. Lay the pipe before the green flooz starts to flow - this single verb cast the template of the real-time spatial-connection puzzle.
- Ep. 11Mole Mania (1996) — What a Two-Layer Board of Surface and Underground Taught Us2026-07-04
On July 21, 1996, Nintendo released Mole Mania for the Game Boy, developed by Nintendo EAD and Pax Softnica and produced by Shigeru Miyamoto. With four verbs — push, pull, throw, dig — you carry an iron ball to each screen's gate, across a board that exists in two layers: surface and underground. I dig up this forgotten work as an ancestor of the spatial reasoning found in today's multi-layer puzzles.
- Ep. 10Cursor*10 (2008) — Ten of Me Climb One Tower: The Origin of Self Co-op2026-07-03
In January 2008, Yoshio Ishii of Nekogames posted a single Flash game on his site: Cursor*10. You control the mouse cursor itself; when one life runs out, its recorded actions replay in the next, and you climb a sixteen-floor tower in cooperation with your past selves. I read this small work, built over a single Japanese New Year's holiday, as an origin point of the 'self co-op' grammar in modern puzzle design.
- Ep. 9echochrome (2008) — A Puzzle Where Perspective Becomes the World's Physics2026-06-28
Released for the PSP on March 19, 2008, echochrome translated the 'OLE Coordinate System' — an illusion principle researched by Jun Fujiki at Kyushu University — directly into play. The physics of the world a wooden mannequin walks through is rewritten by the angle you view it from. I re-read this work, which turned the impossible objects of Escher and Reutersvard into a rotating puzzle, within the lineage of perspective puzzles.
- Ep. 8The Lost Vikings (1993) — A Classic of Cooperative Puzzling, Three Bodies Moved One at a Time2026-06-27
Released in 1993 by Silicon & Synapse (later Blizzard Entertainment) through Interplay, The Lost Vikings is a cooperative puzzle in which the player controls three differently-skilled vikings one at a time and must lead all of them to the exit. In Japan it was distributed by T&E Soft under the title Viking no Daimeiwaku. This essay re-reads its era, the quality of thought its three-way cooperation produced, and the lineage that runs from Lemmings and Gobliiins to today's cooperative puzzles.
- Ep. 7Threes! (2014) — One Last Board That Grows by Three2026-06-26
Threes! arrived on the iPhone in 2014. Prototyped in a single night and polished over fourteen months, it lived through a strange reversal when, a month later, the 2048 craze left the original accused of being the copy. We trace the origin of the merge-slide puzzle through the developers' own testimony.
- Ep. 6Submachine (2005) — A Door into the Subnet, and the Lineage of Flash Escape Puzzles2026-06-24
On 15 September 2005 the Polish cartoonist Mateusz Skutnik posted a single Flash game on his own website. It was simply called Submachine. Later renamed Submachine 1: The Basement, it became the seed of a ten-part escape-puzzle lineage. I read this hand-drawn browser work, one that never sat on Steam at the time, as a chapter in the history of escape puzzles.
- Ep. 5Adventures of Lolo (1989) — The Emerald Framer and the Single Solution2026-06-23
In 1989 HAL Laboratory released Adventures of Lolo on the NES, distilled from the 1985 MSX title Eggerland Mystery. On an 11x11 board, pushable framers and moving enemies converge on a single solution. I read this Sokoban-descended single-screen logic puzzle as a node in a long genealogy, one that codified its ideas well before the modern grid-puzzle wave.
- Ep. 4Lemmings (1991) — The Source of Indirect-Control Puzzling, Where You Move the World and Never the Creature2026-06-23
On 14 February 1991, DMA Design of Scotland released Lemmings and, with it, established 'indirect control': the player never steers a character directly but assigns roles and shapes the world to guide a crowd to safety. This essay re-reads its era, the quality of thought its eight skills produced, and its lineage toward RTS and modern puzzle design.
- Ep. 3The Incredible Machine (1993) — The Toy Box That Made Rube Goldberg Playable2026-06-09
Released in 1993 by Dynamix and Sierra, The Incredible Machine laid gears, balls, fans and cats across a single screen and asked players to build Rube Goldberg contraptions. Assembled in nine months on a $36,000 budget, this toy box—together with its Free Form sandbox mode—became a headwater of the modern physics-and-contraption puzzle. This essay traces the twenty-one years until its own creators put Contraption Maker on Steam in 2014.
- Ep. 2Mario's Picross (1995) — Picture Logic, a Form Born in 19872026-06-02
Released for the Game Boy on March 14, 1995, Mario's Picross translated into play the 'picture-logic puzzle' that two inventors had independently created in Japan eight years earlier. From newspaper puzzle to game, and on to today's Steam nonograms, this is the lineage of a single logic puzzle that survived almost half a century without changing its core.
- Ep. 1Sokoban (1982) — The 44-Year-Old Prototype of Meta-Puzzles2026-05-24
In 1982, Hiroyuki Imabayashi of Thinking Rabbit released Sokoban. Forty-four years later, walk-and-push is still the bedrock of Baba Is You and Patrick's Parabox. Reading the lineage backward from period context.
