Can somebody tell me is there any way to create multiple game account with one email account?

If you google tempmail you can get a temporary email that disappears when you leave the page so all you need to do is leave it open in a tab until you've linked your new account

No there isn't a way, you need different addresses, but you can set up extra email addresses easily.

Yes, in a way. If your email is [email protected] you can use that on your first account. On additional accounts use the email addresses [email protected] or [email protected], etc.

IM30 sees these as separate email addresses and allows each account to bind to each variation.

However, gmail sees them all as the same address and allows all the accounts to funnel answers into a single gmail inbox.

The only drawback is when one of your accounts sends an alert, like 'helicopter has arrived' or 'water storage is full' you can't tell which account sent the message.

I do not know if this trick works with any email providers other than gmail.
