About HYPERBUBBLE
HYPERBUBBLE is a free one-button game that runs in the browser. You press and hold to make the bubble heavy so it drops, and let go so it floats, riding the hills like a skier: hold on the way down, release at the bottom and fly. A year counter shows how far you got, and a pink bar for human flourishing shows how well; the bar leaks as the pace of change rises and climbs only through acts of care, such as adopting orphan risks before they come back with teeth, starving moral-panic fires of attention and using emerging technologies for good rather than riding the hype. At zero the run ends. Holding Shift, or resting two fingers on the screen, slows the world down on purpose, at a cost in flourishing. There is a bestiary that fills in as you meet things, a daily challenge played on the same seed by everyone, a soundtrack that grows with the eras and an optional leaderboard that uses generated pseudonyms. The game is based on the research of Andrew Maynard, Professor of Advanced Technology Transitions at Arizona State University: per the README, nearly every rule is borrowed from frameworks in his work, and the whiteboard look is an homage to his Risk Bites videos. Maynard says he asked Anthropic's Fable 5 model, via Claude Code, to research two decades of his work and design a browser game from it, and the game credits it as devised and coded by Claude Fable 5, over more than 90 iterations. The whole game is one self-contained HTML file with procedural graphics and a synthesized soundtrack; the code is MIT-licensed. Free, no account; the developer says it plays best on a desktop or tablet.
How it was built
VerifiedIn the Show HN post the developer writes: “I asked Fable 5, via Claude Code, to research the past two decades of my research and design a browser game from it”, and calls the result, after more than 90 iterations, a long collaborative effort. Per the genesis blog post, Fable did a deep research dive into his work, created five game-designer agents to propose concepts, passed them to a panel of three AI judges, picked the winning proposal, then debugged, tested and checked the first draft with sub-agents before refining the game with him. The blog's credits list “Claude Fable 5 (Anthropic, via Claude Code)” for research, game design, code, art, music, testing and the self-audit document. The developer does not say whether any code was written by hand.
- DeveloperREADME: “Designed and coded by Anthropic's Claude in collaboration with Maynard, across five generations and ninety builds.” Credits: Claude (Anthropic) for “research, game design, code, art, music, and testing”. — GitHub (2020science)
- DeveloperThe game's “ideas behind this” page: “Devised and coded by Claude Fable 5”. — Andrew Maynard
- DeveloperGenesis blog post (10 Jul 2026): credits “Claude Fable 5 (Anthropic, via Claude Code)” with research, game design, code, art, music and testing. — The Future of Being Human (Andrew Maynard)
Per the developer, Claude Fable 5 in Claude Code researched his work, generated competing game concepts with designer agents and AI judges, built and tested a first draft, and then iterated with him over more than 90 builds and five generations. The game is a single self-contained HTML file with procedural hand-drawn graphics and a fully synthesized soundtrack, with no libraries and no build step; the only server part is an optional leaderboard, a Cloudflare Worker of about 120 lines with a D1 database that stores a board name, a pseudonym, a year, a hill count and a flourishing peak per entry.

Verification notes: Four developer sources agree on the AI claim: the Show HN post of 14 Aug 2026 (22:01 UTC, user 2020science), the README, the game's own “ideas behind this” page and the genesis blog post of 10 Jul 2026 on the developer's newsletter, which names Claude Code. “Fable 5” is the developer's name for the Anthropic model and is kept as written. Team size 1 rests on the README credits, which name only Andrew Maynard and Claude. Gameplay, the leaderboard's data and the MIT licence come from the README (raw.githubusercontent.com); github.com and the GitHub API did not answer our checks, so the repository's dates were not read. The page loaded on 4 Nov 2026 (build 101 in its notes); its only network calls go to the leaderboard at hyperbubbleboard.fvture.net, and no calls to AI services were found. The blog post of 10 Jul 2026 already shares a link to the game, and the game first lived at fvture.net/hyperbubble; the post gives version numbers (“updated to version 3 July 25 2026”, later version 4) but no launch date, so no release date is recorded. The README says the HYPERBUBBLE name, the social-card artwork and Maynard's writings and frameworks are not covered by the MIT grant. The developer said on HN that mobile play works but is not tuned yet. The game was not played through.
Development history
The developer shares the game in a newsletter post on how he asked Anthropic's Fable 5 to make it, with Fable's own self-audit of the process; the game is then hosted at fvture.net/hyperbubble.
Per the newsletter post, the game is updated to version 3.
The developer posts the game on Hacker News as a Show HN, after more than 90 iterations.
