Rights holder / original work: Microban level collection (David W. Skinner)
Includes 50 levels from the Microban collection by David W. Skinner, credited by name in the game. The game's own third-party notice says BOXXY claims no copyright in the Microban layouts and that its repository contains no separate express commercial licence from the creator. The site also loads a Sokoban solver from another author's repository (dangarfield/sokoban-solver), for which, per the same notice, no explicit redistribution licence was visible. (Sam Cornwell)

About Boxxy
Boxxy is a free box-pushing puzzle game in the Sokoban tradition for desktop and mobile browsers: you push crates onto targets, one move at a time. It has a 50-level BOXXY Originals pack and more original packs (The Jigsaw, Exponentially, Alphabet Soup, Starry Night, Static Noise, Four Leaf Clover and others) that unlock as you play, plus 50 levels from the classic Microban collection by David W. Skinner. There is a Boxxy Daily puzzle with a fastest-time leaderboard, undo and restart, a guided solve, a ghost of your best run to race, mouse, touch, keyboard and swipe controls, a wardrobe for the character, music, a hidden level maker and many Easter eggs. Accounts are optional: you can sign in with email or Google to save progress in the cloud, or download the whole game for offline play. The interface is in eight languages. The developer, Sam Cornwell, who says they had started and stopped learning to code for about thirty years, writes that it was made solely with ChatGPT in a browser and that ChatGPT wrote a huge amount of the actual code, while the developer designed the structure, tested everything and rejected bad solutions. All of the original levels were designed by hand, without ChatGPT or generative AI. There are no ads and no charge.
How it was built
Partially verifiedIn a post on r/vibecoding (21 Aug 2026, UTC), the developer writes: “It was made solely with ChatGPT in a browser. I have not even touched Claude once.” The game was built with “ChatGPT 5.6 on high in a browser” through a series of requests, answers, outputs and iterations, without background agents; when a chat filled up, the developer started a new one and supplied a zip file with the whole project. The developer says ChatGPT “has written a huge amount of the actual code”, while the developer had to understand the structure, decide how it should work, test everything, reject bad solutions and sometimes tell it to redo the whole approach, and occasionally adjusted code by hand. The level design was done entirely by hand, without ChatGPT or generative AI.
Built in ChatGPT in the browser by a non-programmer over about two months, per the developer: first the bare game (a level, a character, box movement, level completion), then level packs, then visuals and the systems behind them. At the time of the post it was about 30,000 lines of JavaScript, CSS and HTML (about 25 MB), on version 282 after around 300 iterations, with user accounts and server-side code, a contact form, a level maker, a level-pack builder and a solver. The developer says the total cost was about £50, mostly the OpenAI subscription plus a domain. Accounts and cloud saves run on Cloudflare D1. Per the game's third-party notices, a Rust/WebAssembly Sokoban solver by another author is loaded from outside the site.

“It was made solely with ChatGPT in a browser. I have not even touched Claude once.”Verification notes: AI use, workflow and figures from the developer's post on r/vibecoding by u/samcornwell (21 Aug 2026, 18:51 UTC), read from the Arctic Shift Reddit archive on 7 Nov 2026; it links boxxy.io. The post says ChatGPT “has written a huge amount of the actual code” and that the game was made “solely with ChatGPT”; no percentage is given, so no AI code share is recorded. The cost (about £50) is in pounds and is not converted. Developer name, packs, features, languages and the legal and third-party notices from boxxy.io, its LICENSE.md and THIRD-PARTY-NOTICES.md, read on 7 Nov 2026. The game is source-available under a proprietary licence, not open source. The bundled Microban levels and the externally loaded solver are third-party material, described in the notice below. One music track is titled “Tetris Piano”; its content was not checked. The site uses PostHog analytics in cookieless mode and calls no AI services. The release date is not stated; the game was public by 21 Aug 2026. Team size is not stated (the site thanks several playtesters). The game was not played.
