You can go to play in a terrestrial or traditional online casino but you will find that there is no enough number of games to play. In those places, the gaming rules are the same: you do not have to play unless you have money to pay some chips. No bonuses are available there.

But if you come to play in an online casino, you will be provided with hundreds of online games. For slots for example, you can have many variants but the rules remain the same, except for bonus. Bonus is now a very good marketing tool to attract the most players, so online casino operators have to give you as many as you need to let you win. You sign up for free and you get welcome bonus right away. You continue playing and betting on the best online games and you will be awarded different bonuses.
