About 大富翁 - 好运之城
A Chinese-language property-trading board game that runs in the browser on a computer or phone, with no sign-in. You and three computer opponents with names and personalities (林小满, 顾星野, 唐可可 on the page) start with 6,000 coins and move clockwise around 24 city landmarks, buying land, building and collecting rent; a coloured strip marks each district, and owning a full colour set raises its rent by 50%. Item shops and random-event squares fill a strategy backpack of up to six cards, one of which you can play before each roll, and the city's market conditions change every four rounds. The site offers a single-player mode, three game lengths and an autosave that keeps one game in the browser. An online mode matches you anonymously with one other human player; if no opponent is found within two minutes, a computer player takes the seat. The developer, ttkit on V2EX, says the game was made over a weekend with "GPT-6 Astra", together with a Tank Battle and a match-three game, as a recreation of arcade games played in childhood, then added the online mode after requests in the thread. A WeChat mini game version with matchmaking and friend rooms followed in October 2026. The game is part of TTKit, the developer's site, which also hosts other small games and AI tools.
How it was built
Partially verifiedIn the V2EX thread of 6 Sep 2026 the developer writes that over a weekend they used "GPT-6 Astra" to make three arcade games played in childhood, Tank Battle, Monopoly (大富翁) and a match-three game ("周末用 GPT-6 Astra 做了坦克大战、大富翁、消消乐三款小时候玩的街机游戏"), and praises the model's ability at making small games. Asked whether the professional-looking screenshots were also produced by Astra, the developer replied "对，都是 Astra 生成的" (yes, all generated by Astra); asked how many tokens it took, "roughly over 10 million" (粗算是 1000 多万 token); asked how the prompt was written, the developer quoted "增加一个大富翁游戏，要求界面精致，道具丰富，可玩性高" (add a Monopoly game with a polished interface, plenty of items and high playability). The follow-up thread of 15 Sep 2026 says the online mode was added in spare time "as far as AI can do it" (在用 AI 能做到的情况下), and the WeChat thread of 20 Oct 2026 ends by calling the project vibe coding. "GPT-6 Astra" is the developer's own wording; the threads do not name the product or service used, so the tool is recorded as undisclosed.

Generated with an AI model the developer calls "GPT-6 Astra" over a weekend from short prompts, per the developer, and then extended in public: after players in the first V2EX thread asked for multiplayer, the developer added anonymous online matches with a computer stand-in, then released a WeChat mini game version with matchmaking and friend rooms. The developer says the mini game took little development time and that most of the month before its launch went into the required ICP filing (备案) and WeChat review.

“周末用 GPT-6 Astra 做了坦克大战、大富翁、消消乐三款小时候玩的街机游戏。”Verification notes: AI use comes from the developer's three V2EX threads (6 Sep, 15 Sep and 20 Oct 2026, China time) and the developer's replies in the first. The developer writes in the first person but never states a team size, so the developer type is recorded as undisclosed. "GPT-6 Astra" and "Astra" are quoted as the developer wrote them; we did not confirm what model or service the name refers to. The developer says the games were made with the model and quotes the one-line prompt used for this game; the reply "都是 Astra 生成的" answers a question about the screenshots (效果图), not the code. No share of AI-written code is given; it is recorded as vibe-coded on the strength of the made-with-Astra statement, the quoted prompt, the token count and the closing reference to vibe coding. Board, landmarks, starting money, items, market changes, modes, autosave and the online rules come from the game page and the site's game list on 4 Nov 2026; the meta description mentions three game lengths and the game list mentions nine item types, which were not counted in play. The computer opponents and the stand-in player are called AI on the page; nothing on the page describes AI-generated content during play, and the game was not played. The web release date is the date of the first thread. The WeChat version was announced with a QR code only; we could not open it. The TTKit site also offers AI chat, writing and image tools, which are separate from the game.
