No, creating a Chef ID is not mandatory, you can still enjoy Star Chef 2 without it. However, we strongly recommend linking your game to Chef ID to make it much easier to restore your progress if you reinstall or switch devices and also you will be able to play on multiple devices.
If you choose not to link, please note down your Game ID for future reference. In case you need to move your game to another device or recover it, you can share your Game ID with us, and we’ll help you restore your progress. In case if you do not have your game ID it would be difficult for us to find and recover your game.
