The Direct Way
Open Roblox Studio and load your game, or open the one you want to duplicate from the home screen. Go to File in the top-left corner and select Duplicate Game. That creates a brand new place with a new ID and a clean output folder. Everything inside — scripts, models, meshes, sounds, UI — gets copied into a fresh project. This is the most reliable method for How To Copy Games On Roblox if you are starting from Studio rather than trying to pull things from a published experience. The downside is that this only works for games you already have open access to, meaning you own them or they are set to public or group-owned with your membership. If you try to duplicate a game you cannot open, it simply will not be an option. There is no backdoor for that, and you should expect nothing different.
How To Copy Games On Roblox Using Asset Import
When the Duplicate function is not available, which happens often with group games you do not fully control or experiences with locked assets, you need to use the export and import system instead. Here is how it actually works in practice. First, identify every asset you want to carry over. Scripts go into a separate folder inside the Explorer window, right-click, and choose Export to File. Do the same for models and meshes. I used to export everything individually, which took forever and produced a messy bin of random files. The fix was to create a dedicated Copier folder in the workspace during development, put all target items in there before exporting, and then use the Package Manager to bundle them into a single .rbxm file that I could drop into a new project. Paste that .rbxm into the new place, then use Insert -> Local Plugin or just drag it from your file system directly into the Explorer. Each object retains its internal IDs when imported this way, so local scripts referencing the model will still work, but global scripts that hardcoded asset IDs into RemoteEvents or data stores will break. You have to go through and patch those manually. I learned that the hard way on a project where I copied a game with about forty scripts and then spent three hours tracking down broken references because I did not check the DataStore keys first.
What People Miss About This Process
There are two things that consistently trip people up when they try to copy a Roblox game. The first is server-sided versus client-sided data. Scripts that live in ServerScriptService reference game state differently than ones in StarterPlayerScripts. When you copy a game and deploy the duplicate on a new place ID, the server environment is completely fresh. Anything that stored data tied to the old place ID, whether through DataStore service or BindableEvents that broadcast the place number, will silently fail on startup. Check your DataModel settings and look for any PlaceId references in the code before you spend time testing. This usually takes about ten minutes and saves you from debugging what looks like a broken game for hours. The second issue is group asset permissions. If a game was built using group-only models, you cannot duplicate those assets out of the group library into a personal project unless you have at least Builder role or higher in that group. The export option will be grayed out for certain files. I ran into this with a map build from a group that had fifty custom meshes locked to Builders only. My workaround was to request a role increase, export the models while in Builder status, and then downgrade after. Some groups deny that request outright, in which case you can still access the meshes inside the original game in Studio by opening it as a guest if the group allows it, then selecting each mesh and copying it manually into a new place.

Alternative Approach When Duplication Fails
Sometimes the game you want is published and you only have viewer access. In that case, you can use the in-game developer console to pull certain assets, though this is limited and incomplete. Open the experience, press F9 to bring up the output window, and type in commands to list available models. This is not a reliable method for full game copying and you should not rely on it for anything production-level. It works for grabbing a handful of free models that the developer accidentally left unparented in the workspace, but most well-made games keep their assets nested inside models or in hidden folders. The honest answer is that there is no clean way to copy a published Roblox game you do not own or have permission to modify. The duplication tools are designed exactly for that: only accessible to people who can open the project. If someone is selling you a tool that claims to clone published games from the outside, it is either malware or a scam, and you should avoid it entirely. If you have the source and just want a second version to experiment with, the Duplicate Game function inside Studio remains the fastest path. It usually takes about two minutes for a mid-sized game to duplicate, including the time it takes to rename everything and clear out the test folders. A larger game with thousands of models might take around ten minutes depending on your machine. That is the realistic timeframe. Anything faster is lying to you.
