Why is registration required?
In game there is an opportunity to play through the guest account, but in this case we don't guarantee safety of the data, therefore we recommend to be registered in the app.
If you play through the guest account, you can link it to any social network. Pay attention that after you link your account it is impossible to return to the guest account.
It is possible to link a guest account with chips and gold listed in it with the account of a social network only once.
