Can you make a Roblox game on your phone?
Yes. You can make and publish a Roblox game from your phone browser with studs.gg. Describe the game you want, let it build the world and scripts, then publish it to Roblox. You do not need Roblox Studio or an API key to copy. A typical build takes about an hour, and you play the finished game on Roblox, not inside studs.gg.
Key takeaways
studs.gg runs in your phone browser, so you do not need Roblox Studio.
A small, clear prompt is easier to build from than a huge game idea.
A typical build takes about an hour, and the 3D preview is not playable.
Connect your Roblox account once, then publish your finished game from your phone.
What do you need?
You need a phone browser and a Roblox account. Go to studs.gg and sign in with Roblox. You do not need to install Roblox Studio. The whole process, including connecting your account and publishing, works on a phone.
A script is a set of instructions that makes parts of a game work. studs.gg writes the scripts for you. You describe the game in plain words.
What should you write in your game prompt?
A prompt is the description you give the game maker. Say what kind of game it is, what the player does, how it should look, and how big it should be. Keep the first idea small.
For example, try this:
Make a small forest obby. Players jump over fallen logs, cross two bridges, and reach a cabin. Use bright colors and add a checkpoint after each section.
An obby is a game where you move through jumps and obstacles. You could also ask for a small tycoon, where players build up a business or place by earning and spending in-game money.
When you tap Build, studs.gg may ask a few questions about your idea. Answer the ones that matter to you, then choose a game concept. For more prompt tips, read How to write a prompt that works.
What happens while studs.gg builds the game?
studs.gg builds the world and writes its scripts. A typical run takes about an hour, so it is not instant. You do not need to keep the browser tab open. You can add your email in Account and turn on finished-run notifications.
When the build is done, you can look at a 3D preview of what it made. That view is not playable. To play, you need to publish the game to Roblox.
How do you publish from your phone?
Open the publish menu under your finished game and tap Connect Roblox. Studs Connect opens Roblox's sign-in page. Sign in to the same Roblox account you use with studs.gg. It sets up the games and publishing key needed for studs.gg to publish. You do not have to create or paste an API key. You only need to connect once.
Then pick one of the games studs.gg set up and tap Publish. When publishing finishes, use Open in Roblox to view your game. See Publish your game to Roblox for the steps and what to do if publishing fails.
What if you want to change the game?
Send a follow-up message in the same project. Ask for one clear change at a time, such as adding another checkpoint or making a shop near the starting area. Small requests are easier to follow than asking for a whole new game at once.
You can see the build before publishing, but you cannot play it inside studs.gg. When you are ready, open studs.gg in your phone browser, describe your first small game, and tap Build.
