The main reason to pick up one of the top Book of Ra games or Novoline online casinos is their bonus quality. They come in many forms so we will focus primarily on our favorite ones. The best bonus types to play online slots in general are 1st Deposit (welcome) bonuses, which have NO DEPOSIT bonuses and FREE SPINS.
Casino slot games that are designed with high volatility require a solid balance because it will take a lot of bets without wins before you hit the lucky punch. Bonuses are a welcome incentive to play the Book of Ra online. It will buy more time before you enter the solid free spin feature with huge wins. Our advice is not to treat them equally. They are not 'money for nothing.' You must keep in mind that the most important aspect of the Book of Ra bonuses is the wagering requirements.
Before you are able to withdraw bonus money from an online casino you need to meet the wagering requirements. Usually, they range between 25-50x the bonus amount. For example: if you take a welcome bonus of €100 and the requirements are 30x.... you need to rollover the bonus amount 30 times (30 x 100 = 3,000). So it will take €3,000 worth of bets before you are able to withdraw your money. It is worth it for high-variance slots (such as Book of Ra,Book of Dead, Lord of the Ocean) where you need to play a longer period of time on smaller bets. The lower requierments are, the better is bonus. It's as simple as that.
The welcome bonus that casinos offer targets potential new customers. You can claim it after signing up for your 1st Deposit. It usually comes in the form of a matching bonus amount. That means that if you deposit €100 you will be awarded another €100 bonus amount so your balance will be €200. Furthermore, many casinos offer FREE SPINS on a slot game determined by the T&C of the casino. FREE SPINS come as an addition to the matching amount after your 1st deposit as a welcome package. These are the most lucrative online casino offers and we highly recommend that you claim them!
You should always take NO DEPOSIT and FREE SPINS BONUSES wherever you can. Why? Because they are risk free. What that means is that you play with real money that can be potentially withdrawn without making a deposit. No Deposit bonuses are usually €5-10 a player recieves after a signing up for a new casino PRIOR to the 1st Deposit. Free Spins, as the name suggests, are gratis spins on slot game for real money without making a deposit.
