Online Casinos FAQs

Which Online Casinos Have The Best Payouts?

Casino games, ultimately, are the decider in whether you’re going to get good payouts while playing. Each one has its own unique Return To Player rate, with blackjack taking the top spot with a theoretical RTP of 99.54%.

For our casino game reviews, we always include the RTP so you know exactly what your chances are.

When it comes to online casinos, some do offer bigger bonuses that can lead to bigger payouts as well as daily tournaments that offer huge prizes. We recommend always checking out a casino’s promotions page to check what offers you can benefit from, to decide if they’re likely to pay out more than other sites.

Which Online Casinos Are Legitimate?

Veteran players will definitely know the answer to this one – it’s all about the licenses a casino has. If the site has been licensed by a reputable country’s gambling commission, such as the UK or Malta, then you know that the casino has been investigated and given their seal of approval.

To see what license a casino has, be sure to scrutinise their terms and conditions or check the very bottom of the site’s homepage. If you can’t see any information about a license, we really wouldn’t recommend playing with that casino because there’s no way to guarantee that it’s safe to play at.

Do Online Casinos Pay Real Money?

Don’t get bogged down in the many different types of bonuses there are at online casinos; at the end of the day what the experience boils down to is you depositing your money and either losing it or gaining more.

As long as your luck is in, you can definitely come away from a casino having won real money – but always check the wagering requirements first.

Which Online Casinos Are The Best?

There are numerous categories to judge an online casino by, such as how many games they have, the bonuses they offer new players and if they’re licensed by the best authorities. Really, the decision is up to you because every casino is different. For a safe bet, we recommend trying out one of our recommended sites above as they all score very highly in each category.

Which Online Slots Payout Best?

As mentioned earlier, every slot has a different Return To Player rate and volatility, meaning that some will pay out more often and some will pay more in single hits. Every slot that we’ve reviewed on our site features an RTP number, so don’t forget to check it out before you commit to playing a Video Slot. The top providers such as NetEnt, Microgaming and Quickspin are well known for launching high RTP games. For example, NetEnt’s Mega Joker has the highest Return To Player rate available at 99%.
