What kind of bonuses can you receive at online casinos?

Online casinos offer many bonuses to their players in order to attract them and also to give them better odds at winning big money on the Internet. Different kinds of bonuses exist: there are those offered as a welcome gift, that do not commit players to anything and just allow them to play online casino for free, with no deposit. Then, there are bonuses that are being offered when players deposit money on the website: those bonuses increase the amount of money players deposit so they are then able to play with more money than they actually spent. Finally, bonuses are also up for grabs on a regular basis during quizzes or contests organised to animate online casino websites.
