Claude Game Maker: How to Make Games with Claude AI

Yes, it's literally Claude under the hood

We're not vague about the "AI" in our AI game maker. Every game on Arcade Sandbox is generated by Anthropic's Claude models, each doing the job it's best at:

• Claude Opus builds 2D games. Platformers, shooters, puzzles, cozy sims — Claude Opus writes the complete HTML5 game (code, canvas art, difficulty tuning) in one streaming pass you can watch.
• Claude's newest frontier model builds 3D games. 3D from text is genuinely harder — cameras, spatial reasoning, WebGL — so 3D builds run on Fable 5, Anthropic's newest model, writing against a lightweight 3D engine we inject. More on 3D-from-text here.
• Claude Haiku sharpens your prompt. Before a build starts, a fast Claude model expands your one-liner into a proper design brief — mechanics, controls, scoring, palette — so a short prompt still gets a thoughtful game.

What "a game made with Claude AI" looks like

Each build is a single self-contained HTML5 game: canvas-drawn art, keyboard and touch controls, scoring, a start screen with your title. It's the same core magic as asking Claude for a game in chat — plus the parts a chat window can't do:

• Hosting and a shareable link the moment the build finishes — no copying code into files.
• Plain-English revisions. "Make the jump floatier. Add a boss every 5 waves." Claude patches the existing game rather than rewriting it, so revisions are fast and your link never changes.
• Reference images. Attach up to three photos or drawings and Claude uses them as art direction — here's how that works.
• A public arcade. Publish free and other players can discover your game. Their first play is free; if they unlock it for 🪙500, you keep 75% (🪙375) as build tokens.

Prompting Claude for better games

Claude rewards specificity — the same skill that gets you better answers in chat gets you better games:

"A neon twin-stick shooter where enemies split in half when shot, down to tiny fragments. Screen shake and particles on every kill. Waves get faster; every 5th wave is a giant boss that splits into a full wave."

"A cozy puzzle game about sorting a magical library: drag falling books to shelves by color and size before the desk overflows. Gentle pace, warm palette, satisfying shelf-complete animations."

Three habits that pay off: name the feeling ("frantic", "cozy", "one-more-try"), name the feedback (shake, particles, streak celebrations), and name the ramp (what makes minute five harder than minute one). The full method is in How to make games with AI.

Claude game maker vs. asking Claude directly

Full honesty: you can ask Claude to write you a game at claude.ai, and it will. If you're comfortable saving HTML files and hosting them somewhere, that's a fine DIY path. Arcade Sandbox is for when you want the finished experience — build, revise, host, share, plus an arcade of other people's creations — in one place, with the model routing, 3D engine, and prompt-sharpening already tuned for games. That focus is the product. (For how we compare to other platforms entirely, see the honest comparison.)
