To post a Roblox game, start by opening Roblox Studio. Launch the program and open the game you want to publish.
Next, select File from the top menu and choose Save to Roblox. Fill in the game name, description, and other settings. You can always update these details later.
Then, set your game permissions. Go to File, then Game Settings, and select Permissions. Set the game to Public for everyone to play or Friends for limited access.
After that, publish your game. Return to File and select Publish to Roblox. This action will make your game available on the Roblox platform.
Finally, share your game by visiting the Creator Dashboard. Find your game, click the three dots next to the game name, and select Copy URL to share the link with others.
By following these steps, you can successfully post your Roblox game and share it with the public or friends.
