Quadrim

项目介绍

Quadrim is four-in-a-row played in a 4x4x4 cube — the game also known as Qubic: 64 cells, 76 winning lines, most of them invisible until someone uses one on you. Author Edwin Vermeer built it with Claude Code on the €15-a-month Pro plan in 8 working days spread over 4 weeks, and shipped it to the App Store: “The agent wrote the code. I wrote the idea, answered the questions and made the decisions.” The game is unusually complete for a vibe-coded build: 31 computer opponents forming a skill ladder (from one that “barely notices a threat” to one that plays the solved game perfectly, via Oren Patashnik's 1980 Qubic strategy), chess-like player ratings, quests and streaks, pass-and-play, a tutorial that teaches the lines rather than the buttons, and fully offline play. It is free with a daily limit, with two optional purchases (€2.99/year unlimited, €4.99 unlock-all). What makes Quadrim special as a project is the process, not just the game: the repo holds every prompt in order, 48 tickets, 183 commits, ~18,000 lines of Dart plus ~16,000 lines of tests — and a log of 396 numbered decisions that the author calls the most valuable thing he made. Art direction came from Claude Design, with Microsoft Copilot writing the image prompts and ChatGPT generating the opponent portraits. Quadrim 是一款 4x4x4 立体四子棋游戏（即 Qubic：64 格、76 条获胜线）。作者 Edwin Vermeer 用 Claude Code（€15/月的 Pro 套餐）在 8 个工作日内建成并上架 App Store。游戏内容出奇地完整：31 个电脑对手组成的天梯（从“几乎注意不到威胁”到按 1980 年 Patashnik 必胜策略走出完美对局）、国际象棋式段位分、任务与连胜、双人同屏、离线可玩。这个项目真正的看点是过程：仓库里按顺序记录了全部 prompt、48 张 ticket、183 次提交、约 1.8 万行 Dart 代码——以及作者称为“最有价值产出”的 396 条编号决策日志。
