To open your inventory in Roblox on a PC or Mac, click the ‘Backpack’ button on the lower bar. Alternatively, you can press `Windows + CTRL + O` to access your inventory quickly.
If you’re using a mobile device, tap the ‘More’ button at the bottom of the screen, then select ‘Inventory’. This allows you to view and manage your items easily.
On a console, press the ‘D-pad’ down or use the specific button set by the game settings. The method might vary, so check for a ‘Backpack’ icon or the game’s instructions if needed.
Remember, game creators can customize controls, so the exact steps might differ slightly. Always look for the ‘Backpack’ icon or refer to the help section for guidance.
