The most appropriate online casino bonus for you would be the one that increases your chances of winning. And this can indeed happen if you make use of the bonus money in a game that you are comfortable with and know how to strategize. So the first rule in selecting a bonus would be to consider only those bonuses that are connected with games that you are most likely to play.
But there’s more to it. And complete information can only be obtained by reading the terms and conditions related to a given bonus. If you have to choose between a free, no-deposit bonus and a deposit bonus then you first need to compare the wagering and cashout related conditions attached with these. A no-deposit signup bonus that can often be to the tune of a few hundred dollars will carry wagering terms that a newbie may find hard to fulfill. But pro gamers, forever on the lookout for a good bonus, may actually welcome a good no-deposit bonus. So, basically apart from the casino requirements, you also need to factor in your gaming skills and intentions.
It will help to keep in mind that although games like slots and keno come with very good bonus offers as compared to blackjack and other games of skill; they invariably have a substantial house edge that makes winning a little difficult.
