What defines a top online casino?

When choosing the right online casino for your gaming needs, there are many different aspects you will want to consider in order to ensure you receive the absolute best casino experience.

While your initial instinct might be focus on who can offer you the best bonus for your deposit, you will also want to delve deeper into factors such as top tier customer service, payout rates and an operator’s overall reputation.

To make the casino you choose can meet all your priorities and you are entirely satisfied with the services you receive, make sure to use online casino reviews to help you determine which site is the right one for you.

Any top rated online casino will receive outstanding grades in the following key aspects:

1 Easy to use website

Playing casino games for real money should never be a complicated experience. A quality casino will offer a website that makes it incredibly easy for you to sign up, deposit, and find your favorite games.

Choosing a casino with an attractive and easy to navigate design will guarantee your gaming experience is as smooth as possible.

2. Ability to bet in local currencies

While they may operate in your country, some casinos will not actually carry your local currency – forcing you to play in a foreign coin.

This may not only make it harder for you to keep up with the value of your bets, but also likely make you give up small percentages of your funds every time you exchange currencies.

The best online casinos for real money will accept all major currencies such as USD, Euro, NZD, CAD, and Pound amongst others.

3 High payout rates

Getting paid out handsomely when you win is what casino games are all about!

Some casinos offer higher payout rates on their games than others, as their game collection focuses on offering games with a lower House Edge.

This not only means you’ll get higher payouts when you win, but also that you may win more often as well!

High payout casinos also tend to offer a fast selection of payment methods, allowing you to cash out your winnings in record times!

4 Great promotional offers and bonuses

While you don’t want to choose a sub-par casino just because of their bonuses, you will definitely want to choose the best casino that can offer you plenty of attractive promotions.

To get the best value for your money, keep a lookout for reputable operators that can offer you a strong welcome package, substantial reload bonuses, and a rewarding loyalty program.

5 High reputation

With so many options to choose from, an online casino’s reputation is everything.

Any well informed player will shy away from a real money casino that is not well reviewed by other players or trusted review sites, as choosing a disreputable casino is not the kind of gamble you’ll want to make.

To ensure you only choose well regarded operators, make sure they are properly licensed by respected authorities and governing bodies, such as the MGA and the UKGC, and verified fair by independent auditors such as eCogra.

Different types of real money online casinos

Real money online casinos can be found in all shapes and forms, some of them specializing in a particular area while others try to offer it all.

Our website features Live dealers, high payout, fast withdrawal, and no account casinos.

The selection is always widening, and it can be hard to find trustworthy options to play. Thankfully, Casino Senpai is here to guide you through the different types of online casino and shows you what you can expect from each of them.

Live casino’s

Broadcasted live from actual casinos floors and realistic studios, Live casinos takes the land based casino experience directly to your home! Place bets in real time and watch as dealers physically spin the wheel or deal the cards to determine the winner.

The best part? At live casinos you can interact directly with live dealers and fellow players from around the world via chat, making your favorite online casino games more social than ever!

Highest payout casinos

While most online casinos will offer you a vast selection of games to choose from, not all of them offer games with the same payout odds.

High payout casinos feature games that will actually pay you more when you win – or will pay out more often.

Offering a selection of games with high Return to Player (RTP), these casinos have a much lower house edge in their games than most of the competition – giving players plenty more chances to come out ahead.

Fast withdrawal

An increasingly popular choice with players, fast withdrawal casinos specialize in providing customers with same day cash outs – with some even paid out in a matter of minutes.

Boast top-notch customer service, which is tasked with ensuring every valid payout request is approved within minutes, fast payout casinos offer payout options that can be processed almost instantly, such as e-wallets and cryptocurrencies – allowing you to receive your winnings faster than ever before.

Casinos without registration

Before you can get started, most online casinos will require you to create an account using your personal information, such as name, address, phone number, email, and sometimes even your ID number.

Casinos without registration – also known as a no account casinos – do away with the need to create an account or send in any sensitive information or documents, by instead letting you identify yourself and transfer funds directly with the use of your BankID.

Online Casinos with best bonus

One of the most attractive parts of playing casino online, casino bonuses are an additional reward given to players whenever they sign up or make a qualifying deposit.

While most casinos will offer promotions to get you to try their services, there are some that offer bonuses that are simply out of this world!

Giving you the opportunity to play your favorite games for longer – or discover new favorites without needing to risk your own money – getting the best bonus for your money can go a long way!
