You can choose to connect to several services: 
- Facebook is the service we recommend (it offers you a 30 tokens bonus). 
- Google and Apple are handy and fast connection services because the information is already registered in your device. 
- Connect by email, this method of connection is useful if you don't want to link your social accounts, a backup in the cloud is made. 
- Twitter, if you want to connect via a social network, other than Facebook. 
- Finally, you can play as a guest (caution: your progress will be lost if you change device, if you uninstall the application or if you clean your data from the application!)
