Ultimately, bonuses are strategies by the online casinos to get more visitors to their site. It is similar to promotions in advertising. They are not doing it purely for your benefit. However, that does not mean you cannot gain something from the bonuses and promotions on offer. The main thing on offer is free game time. Freerolls allow you to play in tournaments for free and even give you a chance to enter a big money tournament that will allow you to play a casino game for large prizes. The freeroll will often be sponsored by another firm which is where the online poker room makes its money and you can just sit back and enjoy the gaming experience.

As for the welcome bonuses, deposit bonuses and match bonuses, these allow you to gain some free game play, or eventually win some extra cash. The chances of you winning big and keeping the money before you qualify for the amount of wagers it takes to release the funds from the 'bonus account' into your 'real money account' is relatively low, but it is more than worth it in most cases because of the game time you get for your bonus.
