This bonus is very favorable for customers of CasinoEuro. For a player who has registered using an invitation from another casino customer, the client receives a bonus of 40 euros, and the newcomer will get 20 euros as a bonus. However this bonus can be obtained only if this friend will meet all wagering requirements. Only those who have made at least one deposit at CasinoEuro may refer friends. A referred customer should not be registered with this casino. Having received an invitation message, he or she should open an account within 30 days. To receive an initial bonus, a referred customer must deposit at least 20 euros into the account. Only in this case he or she will be able to get a bonus of 20 euros. The bonus should be wagered 10 times to be able to convert the won amount and withdraw it from the account. For example, having received 20 euros, the referred customer has to make bets whose size should be equal to 200 euros. Only then the bonus prize will be transferred to the account, but it is also necessary to wager it 25 times, i.e. you should make bets whose amount has to be equal to €1,000. Keep in mind that this bonus may be removed if the account balance is less than 1 euro.
