How to make a browser game and publish it online

Step 01Build the game

Open Create, describe the idea and answer a few questions. The platform picks a starting template and the AI coder builds a playable project that you change by chatting: see create with AI. When the idea is a simple arcade or puzzle game, it comes ready from the game constructor. Full walkthrough: how to make a game with AI.

If you already have a game built elsewhere, you can upload a ready build too, for example from Claude Code or another agent connected over MCP.

Step 02Check the test version

Every project has a test copy at {id}-dev.idos.games. It runs the same way the live game will, with sign-in and the game's settings, but players never see it. Before every release:

• play it on a phone and on a computer;
• try it in a private window, as a brand new player;
• check that the store, quests and leaderboards show what you expect;
• give the link to one person who has never seen the game, and watch.

Step 03Deploy it for players

When the test version looks right, deploy it from the version history. The game opens at {id}.idos.games, where {id} is the app ID in lowercase. Two details that save you from bad releases:

• The tested build is the released build. Nothing is rebuilt on deploy, so there are no surprises between what you checked and what players get.
• Code and settings are released separately. Economy, store and quest settings go to the live game as their own action, so a code release never overwrites live prices by accident.

Each game runs on its own address, so games never share browser storage or sign-in data with each other.

Step 04List it in the catalog

The live address works on its own: send it to friends, post it, test with a small group. When you want strangers to find the game, publish it to the idosgames.com catalog in the dashboard. The game gets a page at idosgames.com/app/{id} with a Play button, a description, comments and a share menu.

Link to that page, not to the bare build address, from your own site and posts: a page with a description is what search engines can show, while the build address only opens the game.

Step 05Connect your own domain

On paid plans you can put the game on your own domain, for example play.yourgame.com. Add it in the dashboard, create the DNS record it shows, and the game opens at your domain once the record is confirmed. Details: publishing and sharing.
