- 1.数字连线（1897）——从报纸解谜专栏，到 Flow Free 与 Zip 的时代2026-07-30 · Toki · 约10分钟
1897年，解谜作家 Sam Loyd 在《布鲁克林每日鹰报》刊登了《困惑的邻居们》。1917年，Henry Ernest Dudeney 在自己的著作中将其打磨成一款驾车者谜题；1980年代，Nikoli 将其引入日本，命名为 Arukone 与 Numberlink（数字连线）。2012年，Big Duck Games 的《Flow Free》把它变成彩色圆点与管道，下载量突破一亿；到2025年，这一脉系谱延伸至领英（LinkedIn）的每日谜题《Zip》。本文追溯这条已有120余年历史的规则——不交叉地画出一条线——是如何存活至今的。
- 2.卡库罗（1966）——从 Cross Sums 到加算 Cross，六十年不曾移动的加法格子2026-07-25 · Toki · 约8分钟
卡库罗，英语圈称为 Cross Sums，1966年诞生于美国戴尔公司的一款拼图杂志企划。1980年代，Nikoli 将其引入日本，命名为“加算 Cross”，2005年又经由《卫报》以近乎逆向输出的方式传遍世界。本文将追溯这个既非填字游戏也非数独、专攻加法的格子，为何在六十年间不断更换媒介却始终未曾改变规则，行文将同时参照当年的纸面报道与如今的 Steam 商店页面。
- 3.Sudoku (1979) — How a Nameless Invention Conquered the World's Morning Papers2026-08-22 · Toki · 约3分钟
In 1979, a puzzle called 'Number Place' appeared, uncredited, in an American magazine. This piece traces the 25 years it took to become Sudoku — refined by Japan's Nikoli, carried by a retired Hong Kong judge's homemade program, and finally landing in a London newspaper in 2004 — and the 'logic only, no guessing' design principle that still lives on in the 2024 Steam puzzle collection Islands of Insight.
- 4.Nikoli (1980) — The Reader-Grown Puzzle Magazine, and the Road Sudoku Took Around the World2026-07-02 · Toki · 约5分钟
Puzzle Communication Nikoli, launched in 1980, was Japan's first magazine devoted to puzzles. Its name came from a racehorse; the prototype of Sudoku came from America. This essay traces forty years in which Nikoli's mode of production—reader submissions and handmade problems—gave birth to Slitherlink (1989) and Nurikabe (1991), and sent Sudoku around the world via Hong Kong judge Wayne Gould's generator program, rereading the source of a question at the heart of modern puzzle design: who should make a good problem?
- 5.Slitherlink (1989) — Loop-Closing Logic Born From a Two-Player Paper Game2026-07-23 · Toki · 约6分钟
In June 1989, barely half a year into the Heisei era, Puzzle Communication Nikoli #26 introduced a new puzzle format. Adapted from a two-player paper game called Slither into a single-player pencil puzzle, Slitherlink offers a paradoxical solving pleasure — proving where lines cannot go rather than where they can — and carries a nearly 38-year lineage running through NP-completeness proofs to Steam storefronts in the 2020s. We trace, with sources, the loop-logic Nikoli founder Maki Kaji once called "the son of Sudoku."
- 6.Minesweeper (1990) — The Logic Puzzle Microsoft Built Into a Billion PCs2026-08-17 · Toki · 约5分钟
On 8 October 1990, a small game shipped as one of seven titles in the Windows Entertainment Pack. From 1992's Windows 3.1 onward it came preinstalled on nearly every PC running Windows, and its lineage is said to trace back to Mined-Out, a 1983 ZX Spectrum game by British programmer Ian Andrew. This article follows the genealogy of a logic puzzle nobody set out to design as one — up to 2017's Tametsi, which stripped out the probability and returned the form to pure deduction.
- 7.Hashiwokakero (1990) — Thirty-Six Years of Logic Grown from Numbers Joined by Lines2026-08-18 · Toki · 约5分钟
In 1990, Hashiwokakero debuted in Puzzle Communication Nikoli #31. Its rule — connect numbered islands with bridges until everything forms one network — grew out of an earlier prototype, "Ketsugoshu," that the same contributor "renin" had published in issue #28 the year before. In 2009 it was proven NP-complete; in 2004 it reached Simon Tatham's Portable Puzzle Collection ahead of any Steam release; and in 2023 Nikoli itself ported it to Switch, PC, and Xbox. This article verifies a 36-year lineage.
- 8.Nurikabe (1991) — A Ban on Two-by-Two, Borrowed from a Yōkai's Name2026-08-05 · Toki · 约5分钟
In 1991, Nurikabe debuted under the pen name "renin" in the reader-development column of Puzzle Communication Nikoli #33. Its four rules — size islands by number, connect the rest into a single black sea, and never allow a two-by-two black block — weren't even expected to catch on by the magazine's own editors. In 2004 it was proven NP-complete; its "no two-by-two" rule was inherited by LITS; and in 2025, Steam's Nurikabe World brought the puzzle back under its own name. This article verifies a 34-year lineage.
- 9.Yajilin (1999) — A Board Where Two Rule-Systems Were Grafted Together2026-07-28 · Toki · 约5分钟
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.
- 10.Masyu (2000) — The Loop of Black and White Pearls Born from a Misreading2026-08-03 · Toki · 约6分钟
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.
- 11.马里奥的画线方块(1995) — 1987 年诞生的逻辑2026-06-02 · Toki · 约5分钟
1995 年 3 月 14 日在 Game Boy 上发售的《马里奥的画线方块(Mario's Picross)》,把八年前由两位日本发明者各自独立发明出的「お絵かきロジック」翻译成了玩法。从报纸谜题到游戏,再到当代 Steam 上的 Nonogram。一种逻辑谜题以近乎不变的形态存续半个世纪——本文追溯这条谱系。
- 12.Inside Kaji Maki's Philosophy — placing puzzles as entertainment, never education2026-07-28 · Kizuki · 约12分钟
A study of Kaji Maki (1951–2021), the man who named sudoku, built only from what he said publicly: the philosophy that sealed off brain training — his single biggest commercial opening — in favour of plain entertainment; his obsession with handmade puzzles and the solving process; the forgotten cover price on issue one and the trademark he travelled to Britain for and lost. It covers the dilemmas of reach versus revenue and a small company facing global demand, and closes with Kizuki's reading.
