Publish and manage versions

Studio edits your game’s draft, which saves automatically and is shared with your collaborators. Players never see the draft. They play your game’s current version: the one you last published, or the one you chose in version history. Each time you publish, the draft becomes a new numbered version, and Rally keeps every version.

Publish your game

Only the game’s owner can publish. For collaborators, Publish is grayed out.

1. Test your game to make sure it works.

2. Select Publish in the toolbar.

3. Studio sends your latest edits, builds every script and saves the result as a new version. When it’s done, you see Published version 3 (with your version’s number): players get it the next time they join.

After publishing, the button reads Published, which means players have exactly what’s in your draft. It switches back to Publish as soon as anyone edits the game.

• Players who are already in your game keep the version they joined until they leave. New servers run the new version.
• Publishing keeps your scripts’ TypeScript with the version, so you can restore it later.
• If a script has an error that stops the game from building, publishing stops and names the first error. Select Check in the script editor to see them all. See Find and fix errors.
• If Publish says Nothing new to publish, nothing has changed since the version players have. Make a change and try again.

When an AI app asks to publish

AI apps you’ve connected to Rally can’t publish on their own. When one asks to, and you have the game open in Studio, you see a dialog such as Claude wants to publish Lava Run, with the app’s summary of what changed. Check the game, then select Approve and publish or Deny. A request expires after 5 minutes. See MCP tools for more.

Version history

Select Version history (the clock) in the toolbar to see every published version, newest first. Each one shows its number, when it was published and who published it. The version players get now is marked Live, and compiled only marks a version published without its TypeScript, such as the first version of a game created from a template.

Restore an old version to the draft

Select Restore next to a version to make it your draft again. Everyone editing the game switches to it right away. Players aren’t affected until you publish. Owners and collaborators can restore.

Caution

Restoring replaces the draft for everyone, and it can’t be undone. Anything in the draft that hasn’t been published is lost. To keep it, publish first: you can then use Make live to keep players on the version they had.

If the version is compiled only, its scripts come back as compiled JavaScript. They still work; see Scripts that open as JavaScript.

Roll back what players get

Select Make live next to an older version to make it the one players get, without publishing anything new. New servers run that version from then on. Your draft doesn’t change. Only the owner can do this.

Game settings

Game settings are on the game’s page, not in Studio. Select the back arrow at the left of Studio’s toolbar to get there. Only the owner sees these sections.

Settings has:

Setting	What it does
Name	Up to 60 characters.
Description	Up to 1,000 characters, shown on the game’s page.
Visibility	Private: only you and your collaborators can see and play it. Unlisted: anyone with the link can play. Public: listed in Games for everyone.
Max players per server	From 1 to 100.

Select Save changes to apply them. Settings take effect right away, with no need to publish. A new name shows up in Studio for everyone editing, and a new player limit applies to servers that start after the change.

Below Settings:

• Versions lists every version. Make current does the same as Make live in Studio.
• Delete this game deletes the game with every version and all saved player data. It can’t be undone, and anyone editing it in Studio is disconnected.

Whether a game is 2D or 3D is set when it’s created and can’t be changed.

What players see

Players find your game on its page, which shows:

• a cover Rally draws from your game’s name;
• the name, a 2D or 3D badge, your name and how many times it’s been played;
• how many players fit on one server, such as Up to 20 per server;
• the description, and a Play button.

Until you publish for the first time, Play is grayed out and the page says Not published yet.

Where your game appears depends on its visibility. Public games with a published version are listed under Discover games on the Games page, sorted by most played or newest. Unlisted games aren’t listed, so share the page’s link. Private games are only visible to you and your collaborators.

Players need to be signed in to Rally to play. When a server fills up, Rally starts another one for the next players. See Playing games for the player’s side.
