How to Make a Browser Game with AI, Step by Step

To make a browser game with AI, describe it in one or two plain-English sentences, play the version the AI builds, ask for changes in chat, and publish it to a web address anyone can open.

What kind of game should I start with?

Start small. AI game makers are strongest at small 2D games with one clear mechanic: snake, brick breakers, endless runners, platformers, match-3, memory pairs, quizzes and clickers. Big 3D worlds, online multiplayer and long story campaigns are still hard. A finished small game beats an unfinished big one.

How do I make a browser game with AI, step by step?

• 1. Write one sentence. Name the genre, the controls and how you win or lose. Example: "A neon snake game: arrow keys to turn, eat glowing orbs to grow, game over if you hit your own tail."
• 2. Generate it. Sign up with email or Google, paste the sentence, and get a live preview.
• 3. Play it for two minutes. Note what feels wrong: too fast, too easy, hard to see.
• 4. Fix it by chatting, one change at a time. "Make the snake slower at the start and speed it up every five orbs." Every change is saved as a version, so you can roll back.
• 5. Publish it. Your game gets its own address on amplify.is, and you can connect your own domain later. ## How do I write a good game prompt?
• Name a known genre first, then add your twist.
• Say what the player controls and with which keys.
• Say how a round ends and how scoring works.
• Describe the look in three or four words.
• Leave out everything else; add it later in chat. ## Can I start from a template instead? Yes. Amplify has free game starters you can play and remix: Gem Swap, Dash, Quick Quiz, Spark Forge, Hop, Snake, Pair Up and Bounce. Starting from a working game is the fastest way to learn what prompts do. ## Is it free to make a game with AI? You can build free with your 100 signup credits, no card needed. A quick game uses about 6 credits. ## FAQ ### Do I need to know how to code? No. You describe the game in plain English and change it in chat. ### How long does it take? A first playable version of a small game takes minutes, not days. Polishing it takes longer, one chat edit at a time. ### Can other people play my game? Anyone with the link can play your published game in the browser, no Amplify account needed. ### Is publishing free? Publishing is free, and you can unpublish anytime. When you publish or unpublish, Bing and the other IndexNow search engines are notified straight away. ### What language should I write the prompt in? English. Amplify works in English.
