If you make a deposit in casino then get a Deposit Welcome Bonus. The height of the Deposit Welcome Bonus depends on it how much you deposited. When you make a bigger deposit you get a higher Deposit Welcome Bonus. In the casino without registration and payments you get the No deposit welcome bonus.
The Europa Casino has no No-Deposit-Bonus but a wonderful welcome bonus of $ 2.400.-. Because you can play so long time with this 2.400.- dollar it's like a no deposit bonus or better we think.
