    Your guide into the world of online casinos

    Since we were little we have been fed with gambling commercials, During the 90s they were mostly commercials educating about how to play certain table games such as Blackjack and roulette. During the 2000s the online casinos really took off and we saw more and more casinos popping up online and saw more and more commercials. That is where we got the idea of creating a website that will guide you through all the new casinos and separate the good from the bad. We will provide you with the best campaigns, the best bonuses, the latest bonus spins and of course list the bookies with the best odds.

    What are bonus spins?

    This iconic bonus has gotten a lot of names during the years as it is the most common way of rewarding the customers at a casino. If you are new into the world of casinos you will notice that almost every casino out there is calling them something different. For Example: Mega spins, Super spins, bonus spins, extra spins, free games etc. What you really need to know is that there is really only two different bonus spins out there. The ones with wager which means that if you win on your bonus spins you will have play for a certain amount before you can withdraw your winnings, the second type of bonus spins is the wager free which means that if you win on your bonus spins you can withdraw it straight away. No strings attached.

    What is a casino bonus?

    Almost everyone has taken a bonus before, maybe not a casino bonus but bonuses as in loyalty cards from your favorite store where you will get better prices or even money back. The reason why there is so many loyalty programs out there is cause we as humans like to be rewarded so the scheme works. In the world of casinos however the loyalty programs/bonuses is very generous but a lot of them comes with strings attached and is not very beneficial for you, so what we will do it read all the fine prints for you and only list the bonuses that will maximize your chances of winning big at the casinos. There will still be some strings attached of course, some bonuses you will have to deposit a certain amount and wager the amount of the bonus you receive.

    What is a live casino bonus?

    Live casino is a phenomenon that has really become popular the last few years and is going nowhere anytime soon. To play online at a live casino means that you will have live dealers doing all the work like they would if you went to a land-base casino. The reason why it has become so popular is that you will get the same exact feeling in front of you screen as if you were in a land-base casino without having to dress up and physically walk into a casino.

    What is a sportsbook bonus?

    So if you receive a sportsbook bonus, what the difference? A sportsbook bonus works the exact same way as a casino bonus but you only use it when you place bets on your favorite team on a betting site. The requirements is often that you will have to place the bets on games with high odds, but the best part of receiving a sportsbook bonus is that will have the math on your side since you are betting the majority of the bonus with free money. We recommend that check through the betting sites that we list to receiver the best odds for the game you want to bet on.
