To get a casino bonus it is necessary to open a new account (for further information: begin to play in the casino).   
We recommend you to choose a game room proposed from our casino list, possibly the one that gives a greater bonus on the first deposit. If you look for other casinos, here is an updated online casino list.  
For example if you want to open a new account online and to deposit 100$: lets choose the European Grand Casino (critique Casino Euro Grand) that offers a bonus with 100% deposit.  

With an expense of 100$ we have well 200$ to play in the casino or the 100$ deposited and a bonus of 100$.  

To get an extra bonus from the casino   

But if we want to get a higher bonus?  

The accounts e-wallet that also accepts American Express (as for instance Money bookers, Neteller, EcoCard) gives an additional bonus on every 15% of deposit.  

Then in total, continuing the example of before, we will have in our account:  

1.100$ of deposit  
2.15% of the 100$ deposited  
3.100% of bonus on the 100$ deposited on European Grand Casino  

Total 100$ + 100$ + 15€$= 215$!!!  

A correct use of the bonuses is a good strategy to win money in the casino.
