The most common casino bonuses that is offered today is a match bonus of 100% which basically means that the casino doubles your deposit. You’ll also find that alot of casinos offers Free Spins which is basically free rounds at a chosen slot. These casino bonuses often come with a wagering requirement that you’ll have to finish before you can make a withdrawal.

Safety and Security Measures

To feel comfortable and safe when playing casino online is something that is very important since you give away alot of personal information about yourself that you don’t want to get into the wrong hands. This is extra important when it comes to transactions since you’re giving out your credit card numbers, bank info and such and that’s why all serious online casinos today uses SSL encryptions and all transactions are encrypted with atleast 128 bits.

This might be hard to understand for someone who doesn’t know much about computers, but in English it basically means that your money and other sensitive information is as secure as on the biggest online shops and internet banks. Apart from this the casino also has stored the players money on separate bank accounts which aren’t connected to the casino in any way so even if the casino would get hacked they wouldn’t be able to access your money.

Many casinos online offers very high bonuses apart from the normal match bonuses which are very popular right now, on some casinos we can see up to 300% or 400% bonuses which triples and quadruples your initial deposit.

Different Game Providers at Different Casinos

The casino market has developed fast during the last few years and today there are thousands of different games and slots to choose between. Slots as a rule contains four of five wheels and every slot comes with their own sets of themes with unique bonuses, jackpots, functions and such.

Today most game providers has their own nichés and when you start a slot you’ll quickly notice what provider its from. But how come different casinos has different games? This is because slot providers hire out their slots to casinos and that’s why you wont find the same supplies at all casinos. This can be a charm in itself and many players choose the casino they play on after their supply of games.

The big casino sites which have been around for multiple years usually has up to 30 different game providers to choose between which gives their players a big variety of games. If you’re a new player within the casino world we recommend collecting some Free Spins and then try around among the different slots and find your favorites and then pick your casino after that.

Free is good is a way of speaking that most people probably agree to and here at Slotsoo we’ve taken this into account and found a ton of different casinos that gives you the best bonuses online. The most common free bonuses you’ll find today is Free Spins aswell as free money which you get right after registration and no deposit is required. The amount of Free Spins and how much money you get varies from casino to casino. It’s usually no big amounts we’re talking about, many casinos gives a small part at registration and then the rest with your first deposit.

Taking part of a casino bonus without deposit and free spins but still succeed to win big amounts of money is a dream for many.  Most Free Spins given out by casinos today are on normal slots such as Starburst, Book of Dead and Gonzo’s Quest. Sometimes you can also get spins on jackpots such as Mega Fortune which gives you the chance to millions, completely free.

Casino Gambling Licenses

To be allowed to drive an online gambling website you need to have a gambling license. This means that an responsible authority sees over an actor and controls so that it offers safe, fair and responsible gambling. The most common licenses you’ll find today is Malta License, Curacao License and UK Gambling License. There are some smaller ones aswell such as Gibraltar and Alderney which is also very good.

There are many reasons why a gambling license is important on a casino that you plan on playing on. Firstly, it guarantees that the casino keeps your money safe and separate from their own funds. It also guarantees that all information is completely encrypted so that no information can be leaked to third parts. Lastly, the most important of them all, the games are completely fair with real random generators and pays out accordingly to its RTP.

If you’re unsure you should always double check if the casino has a legit license before playing. The easiest way to do this, is to check on the bottom of the casino’s website. That’s usually where they list their licenses together with a link that verifies their license. If a casino doesn’t list their license that’s a really good warning sign to get out of there. It’s most likely a scam casino that is out to get your money.
