The best AI game maker, compared by what you get

Six AI game makers, side by side

• Roam. Runs on iPhone, free. Output: a playable game with world, art, sound and rules, edited by talking, played solo or with friends. Limits: iPhone only, and games live in Roam.
• Rosebud. Runs on the web. Output: a browser game you remix in a web editor. Limits: the free tier runs on weekly credits.
• Astrocade. A feed of short games that you can also make. Good for quick, short ideas.
• Summer Engine. A desktop app for Mac and Windows: a full 2D and 3D engine with an AI agent. Good if you want files on your computer and more control.
• Roblox Build. A prompt-to-game tab in the Roblox mobile app, announced in July 2026. Limits: an alpha that began in New Zealand and is opening country by country, for age-checked users 9+.
• Google Playground. A Google web platform launched in October 2026. Limits: US only, 18+, and creation runs on credits tied to your Google AI plan.

Pick by the question you actually have

• "Which one works on my phone?". Roam on iPhone, and Roblox Build where it is open. Rosebud and Playground by Google run on the web, Summer Engine on desktop.
• "Which one gives me a game, not code?". Roam, Astrocade and Roblox Build return games you play. Desktop tools give you a project to keep working on.
• "Which one is best with friends?". Roam puts friends inside the game, solo or together. Roblox Build uses Roblox's own social layer.
• "Which one gives me the most control?". Summer Engine or a web editor like Rosebud. More control, more work.

How to test any AI game maker in five minutes

Use the same prompt in each one: "obby on a sky island, my dog is the monster, 3 lives." Then check four things. How long until you are playing? Does a plain change like "add checkpoints" work? Can a friend join or be in it? Does it run where you are?

The best AI game maker is the one that passes all four for you. For phone-first people who want to play with friends, that is the case Roam is built for.
