You can open more than one Roblox game at once, but the method depends on whether you're using the website or the app

The straightforward answer: yes, you can run multiple Roblox games simultaneously on Windows, Mac, or through a web browser. Each instance runs as a separate window or tab, so you can play two games side-by-side, switch between them, or just keep one running in the background. The steps differ slightly depending on your setup, and there are a few things that will slow you down or stop it from working.

Your computer needs enough memory and processing power to handle multiple games at once. Roblox games are not heavy compared to AAA titles, but running two or three at the same time will use noticeably more RAM and CPU. If your computer is already struggling with one game, adding a second will make both lag. You should also know that Roblox may limit how many instances you can run from a single account — this is not a hard block, but the platform does monitor for unusual activity.

Key Takeaways

  • On Windows, you can open multiple Roblox games by launching the app more than once or by opening separate browser tabs, each running a different game.
  • On Mac, the Roblox app will only open one instance at a time, so you must use a web browser to run a second game alongside the app.
  • Your computer needs at least 4 GB of RAM free to run two games smoothly; running three or more requires 8 GB or more.
  • Roblox may flag your account if you open too many instances at once, so start with two and monitor for any warnings.

Opening Multiple Games on Windows

On Windows, the easiest method is to use the Roblox app and a web browser at the same time. Launch the Roblox app from your Start menu, join a game, and leave it running. Then open your web browser (Chrome, Edge, or Firefox), go to roblox.com, and join a different game in a new tab or window. Both will run simultaneously.

If you want to run two instances of the app itself, you can do this by opening the app, joining a game, then opening File Explorer and navigating to the Roblox installation folder. The default location is C:\Users\[YourUsername]\AppData\Local\Roblox\Versions. Find the RobloxPlayerBeta.exe file, right-click it, and select "Open" to launch a second instance. You can repeat this to open a third or fourth instance, though performance will drop significantly.

A simpler alternative is to use multiple browser windows instead of the app. Open Chrome or Edge, go to roblox.com, and join a game in one window. Then open a second browser window (not just a tab — a completely separate window), log in again if needed, and join a different game. This avoids the complexity of managing app instances and often runs more smoothly.

Opening Multiple Games on Mac

The Roblox app on Mac will only open one instance at a time. If you try to launch it twice, the second click will just bring the existing window to the front. To run two games on Mac, you must use the app for one game and a web browser for the other.

Launch the Roblox app and join a game. Then open Safari, Chrome, or Firefox, navigate to roblox.com, and join a different game in the browser. Both will run side-by-side. If you need to run three games, you can open two browser windows and the app, though this will strain most Mac computers unless you have 16 GB of RAM or more.

Some users report better performance by using two different browsers — for example, the Roblox app plus Chrome plus Safari. This spreads the load across different processes and can reduce lag. Test this on your own machine to see if it helps.

What You Need Hardware-Wise

Running two Roblox games at once typically uses 2 to 3 GB of RAM total, depending on which games you're playing. Some games are more demanding than others. If your computer has 4 GB of RAM total, you should have at least 2 GB free before you start, which means closing other programs like Discord, Chrome tabs, or Spotify.

For three games, aim for 8 GB of RAM with at least 4 GB free. Your CPU also matters — a modern processor (Intel i5, AMD Ryzen 5, or equivalent) will handle two games without much trouble. Older or budget processors may struggle, and you'll see stuttering or freezing in both games.

Check your available RAM before you start. On Windows, right-click the taskbar and select "Task Manager," then look at the Memory section. On Mac, open Activity Monitor (search for it in Spotlight), click the Memory tab, and look at the number next to "Memory Used." If you have less than 2 GB free, close other programs first.

Keeping Games Running Side-by-Side

Once both games are open, you can arrange them on your screen by dragging the windows. On Windows, you can snap windows to the left or right half of your screen by dragging the title bar to the edge. On Mac, use Mission Control (swipe up with four fingers or press Control+Up) to see all open windows and drag them to different spaces, or simply resize and position them manually.

If you're using browser tabs instead of separate windows, you can open the second tab in a separate window by right-clicking the tab and selecting "Open in New Window." This gives you two side-by-side windows instead of stacked tabs, which is much easier to manage.

Keep in mind that whichever window is in focus (the one you're actively clicking in) will get priority for your keyboard and mouse input. If you're playing a game that requires constant input, the other game will feel unresponsive. This setup works best if you're actively playing one game and just keeping another running in the background, or if you're switching between them every few seconds.

Account Limits and Warnings

Roblox does not explicitly ban multiple instances from a single account, but the platform monitors for unusual activity. If you suddenly open five or six games at once, you may trigger a security alert or temporary restriction on your account. Start with two games and monitor your account for any messages from Roblox.

If you receive a warning, stop opening multiple instances for a few days and let the flag clear. Roblox is mainly concerned with bot activity and account theft, not legitimate players running two games. As long as you're actively controlling the games (not using automation or scripts), you should not have problems.

If you plan to run multiple games regularly, consider spreading them across different accounts. This avoids any risk of triggering account restrictions and also lets you play with friends who might be in different games at the same time.

Troubleshooting Lag and Crashes

If both games are lagging or one keeps crashing, the first step is to close one game and see if the other runs smoothly. If it does, your computer does not have enough resources for two games. Close unnecessary programs — browser tabs, Discord, streaming apps — and try again.

If one game crashes but the other stays running, the problem is usually that specific game, not your setup. Try a different game in that slot and see if it stays stable. Some games are simply more demanding than others.

If both games crash immediately, your graphics driver may be outdated. On Windows, right-click the desktop and select "NVIDIA Control Panel" or "AMD Radeon Settings" (depending on your GPU), then check for driver updates. On Mac, go to System Preferences > Software Update. Restart your computer after updating and try again.

Frequently Asked Questions

Will running two Roblox games get my account banned?

No, running two games from one account is not against Roblox's terms of service. The platform may flag unusual activity if you open many instances at once, but a temporary restriction is the most likely outcome, not a permanent ban. Start with two games and monitor your account for messages.

Can I run multiple games on my phone or tablet?

The Roblox mobile app will only run one game at a time. You cannot open two instances of the app simultaneously on iOS or Android. You could theoretically use a mobile browser and the app together, but this is not practical on a small screen.

What's the maximum number of games I can run at once?

Technically, you can open as many as your computer's RAM allows, but practically, most computers will run smoothly with two games and start to struggle with three. Running more than four games at once will cause noticeable lag in all of them and may trigger account warnings.

Do I need a better computer to run two games?

Not necessarily. If your computer runs one Roblox game smoothly, it likely has enough power for two. The main requirement is free RAM — close other programs and check your available memory before you start.

Why does one game freeze when I click on the other?

Roblox games pause when their window loses focus. This is normal behavior. Click back on the frozen game's window to resume it. If you want both games to stay active while you're not looking at them, you need to keep both windows visible on your screen at the same time.
