Yes, you can play Roblox on Linux, but there are some limitations and workarounds. Using the Wine compatibility layer, you can run Roblox on Linux. Wine allows Windows programs to run on Linux, although Roblox Corporation has removed support for Wine several times. Currently, it is not officially supported.
Another option is using Waydroid, an Android emulator on Linux. This method lets you play Roblox, but it is limited to games that support mobile devices. For better GPU performance, you may need a custom libndk patch for AMD GPUs and software rendering for Nvidia GPUs.
There are also wrappers like Vinegar and Grapejuice that use Wine to run Roblox. These wrappers offer a user-friendly interface and can be installed through Flatpak repositories. They have been tested on various Linux distributions.
Roblox Studio, used for creating custom content, can also run on Linux using Wine or these wrappers. While playing Roblox on Linux is possible, it often requires additional setup and may not be officially supported by Roblox Corporation.
