You can run multiple Roblox games on the same computer, but the method depends on whether you want separate windows or just multiple game instances

The simplest way is to open Roblox in your web browser, start a game, then open a second browser window (or a different browser entirely) and start another game. Each browser window runs as its own instance, so you can play two games side by side. If you use the Roblox app instead of the browser, you cannot open it twice on the same computer — the app is designed to run only once. However, you can combine the two: run one game in the Roblox app and another in your browser at the same time.

Running multiple games uses more of your computer's memory and processing power, so performance will slow down. On older computers or laptops with limited RAM, you may notice lag, stuttering, or crashes. Start with two games and monitor your computer's performance before attempting more.

Key Takeaways

  • Opening Roblox in two separate browser windows lets you run two games at once, with each window acting independently.
  • The Roblox app itself cannot open twice on the same computer, but you can run the app and a browser window together.
  • Each additional game uses more RAM and CPU power, so your computer may slow down or crash if you open too many at once.
  • Closing one game window does not affect the other, and you can switch between them freely.

Running two games in separate browser windows

Open your web browser and go to roblox.com. Log in to your account and find a game you want to play. Click the Play button and wait for the game to load in a new window. Once the game is running, do not close the browser tab — leave it open.

Now open a second browser window. You can do this by pressing Ctrl+N on Windows or Cmd+N on Mac, or by clicking File and selecting New Window. In this second window, go back to roblox.com, log in again (or stay logged in if your browser remembers you), and start a different game. You now have two Roblox games running in two separate windows. You can arrange them side by side on your screen, or switch between them by clicking on each window.

This method works because each browser window is treated as a separate instance by your computer. Roblox sees them as two different sessions, so the games do not interfere with each other. You can play both games at the same time, or pause one and focus on the other.

Using different browsers to run multiple games

If you have more than one browser installed on your computer — for example, Chrome and Firefox — you can use each one to run a separate Roblox game. Open Chrome, go to roblox.com, and start a game. Then open Firefox, go to roblox.com, and start a different game. Both games run at the same time because they are in different browsers.

This approach can sometimes be more stable than opening multiple windows in the same browser, especially if one game crashes. If Chrome freezes, Firefox keeps running. The downside is that you need multiple browsers installed, and switching between them takes a bit more effort than switching between two windows in the same browser.

Combining the Roblox app with a browser window

The official Roblox app (available on Windows and Mac) cannot be opened twice on the same computer. However, you can run the app and a browser window at the same time. Open the Roblox app and start a game there. Then open your web browser, go to roblox.com, and start a second game. Both games run simultaneously — one in the app and one in the browser.

This combination can be useful if you prefer the app's interface for one game but want to play a second game in the browser. The app and browser are separate programs, so they do not conflict with each other. You can minimize the app to focus on the browser, or arrange both windows side by side.

Why multiple games slow down your computer

Each Roblox game uses RAM (memory) and CPU (processing power) to run. When you open two games, your computer has to manage both at the same time. If your computer does not have enough RAM or a fast enough processor, it will struggle to keep up. You may notice the games running slower, freezing for a moment, or crashing entirely.

Older computers and laptops with less than 8 GB of RAM are more likely to have problems. Newer computers with 16 GB or more of RAM can usually handle two games without much trouble. If you want to run more than two games, you will almost certainly need a powerful computer with plenty of RAM and a fast processor.

Before you open a second game, check your computer's performance. On Windows, open Task Manager (press Ctrl+Shift+Esc) and look at the Memory and CPU columns. On Mac, open Activity Monitor (search for it in Spotlight) and look at the Memory tab. If your computer is already using 80% or more of its RAM, opening another game will likely cause problems.

Closing one game without closing the other

Each game window is independent, so closing one does not affect the other. If you are playing two games and want to stop one, straightforward close that game window or tab. The other game keeps running. You can close the first game, play the second one for a while, then open a new game in a third window if you want.

If a game crashes or freezes, only that window is affected. The other game continues to run normally. This is one of the main reasons people run multiple games — if one becomes unresponsive, you can close it and keep playing the other one without losing progress in that game.

Frequently Asked Questions

Will running two Roblox games at once get me banned?

No. Roblox does not ban players for running multiple games on the same computer. The games are separate, and there is nothing against the rules about playing them simultaneously. However, some individual games may have their own rules about multi-accounting or using multiple instances to gain an unfair advantage — check the specific game's rules if you are concerned.

Can I run two games on the same account at the same time?

Yes. You can log into the same Roblox account in two browser windows and play two different games at once. Your progress in each game is saved separately, so playing both does not cause any problems with your account.

What happens if one game crashes while I am playing two?

Only the crashed game closes. The other game keeps running normally. You can close the crashed game window and open a new one, or just continue playing the game that is still open. Your progress in the working game is not affected.

How much RAM do I need to run two Roblox games?

Most computers with 8 GB of RAM can run two Roblox games without major problems, though performance may be slower than running one game. For smooth performance with two games, 16 GB of RAM is more comfortable. If your computer has less than 4 GB of RAM, running two games at once will likely cause noticeable lag or crashes.

Can I run two games on my phone or tablet?

The Roblox app on phones and tablets cannot run two games at the same time. You can only play one game per device. If you want to play two games on mobile, you would need two separate devices.
