Free Infinite Craft-Style Alchemy Game — Single HTML File (Infinite Alchemy AI)

Infinite Alchemy AI is the Infinite Craft / Little Alchemy loop as a single hybrid file. Start with Fire, Water, Earth and Air, drag two nodes together on the canvas workbench, and discover: Steam, Lava, Energy, Life, Human, Robot, AI — a hand-written recipe book covers the classic chains, and a procedural fallback guarantees every combination produces something even fully offline with no key.

The hybrid part is the hook: paste your own Gemini API key into the top bar (it goes directly from your browser to Google — never to any middleman server, and it isn't stored) and any combination missing from the local book is synthesized live by gemini-2.5-flash into a new named element with its own emoji, which joins your permanent inventory. It's the cheapest possible demonstration of LLM-augmented game content: one fetch call, JSON out, new game object in.

Our review fixed one real recipe bug from the zero-shot generation: "Fire+Air" was defined twice, so the second definition silently overwrote Energy — killing the five recipe chains that depend on it (Portal, Storm, Life, Wizard, Robot) in offline mode. Plasma now comes from Energy+Air and the whole tree is reachable again.

1. Download and unzip — you get index.html and a README.

2. Double-click index.html, or upload it to any static host (shared hosting, GitHub Pages, Netlify, an S3 bucket… anything that serves a file).

3. To embed it in an existing site: <iframe src="/games/index.html" width="860" height="620"></iframe>. That's the whole deployment story.

Community build: one of six HTML5 games generated by the site's owner with Google Gemini 3.1 Pro — each a true zero-shot: one prompt, one file, ~14 seconds of generation, no external libraries, images or audio (all sound is Web Audio synthesis). The exact prompt, verbatim (in Turkish, as written):

Infinite Craft / Little Alchemy tarzında, tek bir HTML dosyasında çalışan 'Infinite Alchemy AI' adında hibrit bir simya oyunu geliştir. Sol panelde keşfedilen elementler listelensin, sağdaki Canvas çalışma alanında elementler sürükle-bırak ile üst üste getirildiğinde birleşsin. İçinde yerleşik çevrimdışı tarif sözlüğü ve prosedürel yedek mekanizma bulunsun; ayrıca üst bara opsiyonel Gemini API anahtarı girildiğinde gemini-2.5-flash API'sine istek atarak yeni elementleri dinamik JSON (isim ve emoji) olarak üretsin.

Verified before publishing: every file read line-by-line, UI strings localized to English for this showcase, and each game deployed and played on the live demo. Found and fixed a real zero-shot bug: a duplicate "Fire+Air" recipe key silently killed the Energy element and the five chains built on it in offline mode. Also confirmed the optional API key goes browser→Google directly and is never stored.
