The Last Computation: A Game About Alan Turing’s Final June

《最后的计算》：一款关于艾伦·图灵生命中最后一个六月的游戏

June Solstice Game Jam Submission This is a submission for the June Solstice Game Jam. Before we talk about the game, let me take you somewhere. It is June 8, 1954. A housekeeper walks into a house in Wilmslow, Cheshire, England. She finds Alan Turing — mathematician, codebreaker, the man who helped end World War II — dead. He is 41 years old. A half-eaten apple sits beside him. 这是“六月至日游戏开发大赛”（June Solstice Game Jam）的参赛作品。在谈论这款游戏之前，请允许我带你去一个地方。时间是1954年6月8日。一位管家走进英国柴郡威尔姆斯洛的一所房子。她发现了艾伦·图灵——这位数学家、密码破译者、曾帮助结束第二次世界大战的男人——已经去世。他年仅41岁。他身边放着一个吃了一半的苹果。

This is the same man who, a decade earlier, sat in a freezing hut at Bletchley Park and broke the Nazi Enigma cipher when the Allied forces had nearly run out of time. His machine — the Bombe — cracked codes that no human could crack fast enough. It is estimated that his work shortened the war by two to four years. Historians believe it saved over fourteen million lives. 这就是十年前坐在布莱切利园（Bletchley Park）冰冷小屋里，在盟军几乎弹尽粮绝之际破解纳粹“恩尼格玛”（Enigma）密码的那个人。他的机器——“炸弹机”（Bombe）——破解了人类无法快速破译的密码。据估计，他的工作使战争缩短了二到四年。历史学家认为，这拯救了超过一千四百万人的生命。

And then, less than ten years after the war ended, the British government chemically castrated him as punishment for being gay. He died alone. The apple — possibly laced with cyanide — was never tested. June is the month Alan Turing was born. It is the month he died. It is Pride Month. And this year, it is the month of this game jam. This game is for him. 然而，在战争结束不到十年后，英国政府因他是同性恋而对他实施了化学阉割作为惩罚。他孤独地死去。那个可能涂有氰化物的苹果从未被检测过。六月是艾伦·图灵出生的月份，也是他去世的月份。这是“骄傲月”（Pride Month）。而今年，这也是举办这场游戏开发大赛的月份。这款游戏是献给他的。

What I Built

我的作品

THE LAST COMPUTATION is a browser-based mystery game set in June 1954, the weeks before Turing’s death. You play as his successor — an operative who has just recovered three encrypted transmissions from Turing’s study, transmissions no one was supposed to find. The game has four chapters: 《最后的计算》（THE LAST COMPUTATION）是一款基于浏览器的解谜游戏，背景设定在1954年6月，即图灵去世前的几周。你扮演他的继任者——一名刚刚从图灵书房中找回三份加密传输文件的特工，这些文件本不该被任何人发现。游戏共有四个章节：

Chapters 1–3: The Codebreaking Each chapter presents an intercepted document, styled as a wartime classified file — paper texture, red TOP SECRET stamp, typewriter ink, all of it. The document contains a ciphertext that you must decode using the same methods Turing and his team used at Bletchley: Caesar shifts and ROT13. These are real ciphers. The game doesn’t hold your hand. You work it out, or you ask for a hint. The decoded messages are fragments of Turing’s final thoughts — haunting, brilliant, and deeply human. 第一至三章：密码破译 每一章都会呈现一份截获的文件，设计风格为战时机密档案——纸张纹理、红色的“绝密”印章、打字机墨迹，应有尽有。文件中包含一段密文，你必须使用图灵及其团队在布莱切利园使用过的方法进行解码：凯撒移位（Caesar shifts）和ROT13。这些都是真实的密码。游戏不会手把手教你，你需要自己解开，或者请求提示。解码后的信息是图灵最后思想的碎片——令人难忘、才华横溢且充满人性。

Chapter 4: The Imitation Game — Inverted This is where the game turns. In 1950, Alan Turing published a paper asking: “Can machines think?” He proposed a test — now called the Turing Test — where a machine tries to convince a human that it is human. The machine that passes becomes, in some sense, intelligent. In Chapter 4, a machine intelligence derived from Turing’s own notes has been watching you work. Now it speaks. And it wants to ask you the questions. Not whether you are smart. Whether you are human. 第四章：模仿游戏——反转 这是游戏的转折点。1950年，艾伦·图灵发表了一篇论文，提出了一个问题：“机器能思考吗？”他提出了一个测试——现在被称为“图灵测试”——即机器试图说服人类它是人类。通过测试的机器在某种意义上就变得具有智能。在第四章中，一个源自图灵笔记的机器智能一直在观察你的工作。现在它开口了。它想问你问题。不是问你是否聪明，而是问你是否是人类。

You have five turns. It asks you about grief, about love, about the fear of endings. It is cold, precise, and deeply curious. Every answer you give is scored — not by word count, but by the texture of your humanity: your hesitations, your emotion, your beautiful imperfection. At the end, it delivers a verdict. The solstice framing is deliberate: June is the turning point of the year. Chapter 4 is the turning point of the game. And June 1954 was the turning point — the darkest one — of one extraordinary human life. 你有五次机会。它会问你关于悲伤、关于爱、关于对终结的恐惧。它冷漠、精确且充满好奇。你给出的每一个答案都会被评分——不是根据字数，而是根据你的人性特质：你的犹豫、你的情感、你那美丽的不完美。最后，它会给出一个判决。以“至日”为框架是刻意为之：六月是一年的转折点。第四章是游戏的转折点。而1954年6月，则是一个非凡生命最黑暗的转折点。

How I Built It

我是如何构建它的

The Design Philosophy The hardest decision was: what should a Turing game actually feel like? I didn’t want a quiz about his biography. I didn’t want a platformer where you jump over Enigma machines. I wanted the player to inhabit the experience — to actually do the things Turing did, and then face the question that consumed the final years of his life. The result: real ciphers, real history, real AI. 设计理念 最艰难的决定是：一款关于图灵的游戏到底应该是什么感觉？我不想要一个关于他生平的问答游戏，也不想要一个跳过“恩尼格玛”机器的平台跳跃游戏。我希望玩家能沉浸在那种体验中——真正去做图灵做过的事，然后面对那个占据了他生命最后几年的问题。结果就是：真实的密码、真实的历史、真实的AI。

The Cipher Puzzles Each puzzle uses a cipher Turing’s team would have recognised. The three shifts — 3, 7, and 13 — increase in difficulty, and ROT13 (shift 13) is the one that requires you to understand the mirror symmetry of the alphabet. The decoded messages are original text written in Turing’s voice, drawing from his published papers and documented thoughts. 密码谜题 每个谜题都使用了图灵团队所熟知的密码。三种移位（3、7和13）难度递增，而ROT13（移位13）则需要你理解字母表的镜像对称性。解码后的信息是以图灵的口吻撰写的原创文本，取材于他发表的论文和记录在案的思想。

The Inverted Turing Test This was the heart of the game and the hardest part to get right. The standard Turing Test asks: can a machine fool a human into thinking it’s human? I wanted to flip it. The machine knows it is a machine. It is not pretending. It is genuinely, analytically curious about what humanity feels like — because its creator, Turing, was fascinated by exactly that question and was persecuted for exhibiting what his society considered the wrong kind of humanity. 反转图灵测试 这是游戏的核心，也是最难做好的部分。标准的图灵测试问的是：机器能欺骗人类让其认为它是人类吗？我想反转它。机器知道自己是机器，它没有在伪装。它真诚且理性地对“人性是什么感觉”感到好奇——因为它的创造者图灵正是被这个问题所吸引，并因表现出他那个社会所认为的“错误的人性”而受到迫害。
