can I create 25 accounts?
Are you for real on this one because, am surprised you can even ask that! Anyway, here is the terms of use of service from Neodice.com for you.
5.4. You are only allowed to register one Account with the Service. Accounts are subject to immediate closure if it is found that you have multiple Accounts registered with us. This includes the use of representatives, relatives, associates, affiliates, related parties, connected persons and/or third parties operating on your behalf.
Owning multiple account is prohibited on not just Neodice.com but on other casinos or/and sportbook as well. Mainly because, creating multi account has been sme means users try to cheat the system. Besides, there is nothing you need to be done on a multi-account that, you can't archive on a single account.
My advice, don't try to violate the Terms of use by thinking, you would multi account and they won't know anyway. That hunch has put so many gamblers in issues like funds confiscation and banning of the accounts on the gambling site. Play in accordance to the Terms of Use and not be sorry!
