Getting Started With Online Gambling

Naturally, any savvy gambler wants the best bang for their buck! But to choose the best online casino, you’ll need to understand the basics…

All casinos (online or land-based) that serve UK gamblers must be registered. And, you can be confident that every registered casino is required to follow strict regulations designed to avoid rigging, exploitation of vulnerable gamblers, or data breaches (hacks). Naturally, The Genie isn’t taken in by unregistered rogue casinos, and only ever suggests legitimate casinos for our lists!

Is Gambling in the UK Legal?

Absolutely! So long as you’re a UK citizen over 18, the Gambling Act of 2005 allows you to gamble legally at any legitimate, licensed casino – whether land-based or online. Gamblers from other jurisdictions should check their local laws, and the T&C’s of the UK casino they want to join, before signing-up.

Are UK Gambling Winnings Taxed

No! Provided you’re a UK citizen, one of the big benefits of gambling is the fact that all winnings are 100% exempt from income tax…

That’s right, however much you win, the tax man won’t get a penny!

How Do Live Casinos Work?

Modern casinos provide a range of options for easy gambling, meaning you can often play through your browser, via a mobile app, or via software you download to your computer. And, if you prefer a ‘real’ casino experience, why not explore live casinos – where you can play against real live dealers online!

Instead of using software simulation, live casinos use a webcam link and feature real tables, with real live dealers, using physical cards, wheels, or dice! And with games that play out right before your eyes, the best live casinos offer an immersive and engaging experience that takes online gambling to a whole new level!

Understanding Bonuses

The three main types are welcome cash bonuses, no deposit bonuses, and free spins…

1) Casino Welcome Cash Bonuses

The most eye-catching bonus offered by many casinos is a welcome cash bonus… And it pretty much does what it says on the tin, offering new members a cash bonus to say ‘Welcome’ when they sign-up and make their first deposit!

Welcome Cash Bonuses, or “Deposit bonuses”, are offered on a percentage basis relate to the amount of your own cash you’ve paid in – so a 100% deposit bonus on a £50 deposit would equal £50 free as a bonus.

2) Casino No-Deposit Bonuses

Believe it or not, no-deposit bonuses are a lot like standard welcome cash bonuses – only you don’t need to make a deposit! (Maybe you guessed that from the name?) A no deposit bonus is the perfect way to start gambling on a site you’ve never used before, since you get to bet using your bonus funds, without putting up your own money…

And, if you don’t like the site that’s no problem, you can walk away without having spent a thing!

3) Free Spins

Instead of offering cash to gamble, many casinos offer free spins for new members instead – that means you get a free go on selected games (often slots – hence ‘free spins’).

Essentially, free spins and cash bonuses are different ways of presenting something very similar – the chance for you to gamble without using your own cash! Just like cash bonuses, some casinos offer no deposit free spins!

It can be worth taking the time to work out which bonus structure gives you the best return!

How Do Wagering Requirements Work?

Casinos that offer the best bonuses have to protect themselves from members simply stealing that money (i.e. signing-up, claiming a bonus, and walking away with the free cash!). The casinos do this by applying wagering requirements that mean that cash bonuses and winnings from free spins have to be wagered (bet) a set number of times before being eligible for withdrawal.

The casinos publish their wagering requirements in their T&C’s – and, though these requirements can look a little complex, it’s worth remembering that they’re really just there to protect the gambling sites from abuse and to allow the casinos to offer their services to genuine gamblers.

Some last words from the Genie

Casinos that make it onto our lists have to pass The Genie’s tests.

Some of the features he loves are a great range of slot games, attentive customer support, and fair odds. He is especially fond of casinos that have a unique and stunning design. Three great examples are Casumo, Mr Green Casino and Wishmaker who is taking their design to the next level. Generous bonuses also catch The Genie’s eye. However, there are some things you need to look out for.

English Language Customer Support

Most gamblers have a trouble-free experience, but, if you run into problems, it can be reassuring to know that there’s quality support on hand from a UK customer support team that speaks your language!

£GBP Currency

You’re already busy working out the odds, thinking about your hand, or where to place your chips, so the last thing you need is to be converting everything into €Euros, or $USD! When you choose a UK casino, you have the convenience of betting in your native currency £GBP!

Legal Protection

Any UK casino needs a license from the UK Gambling Commission in order to operate legally. And licenses are only granted to casinos that offer members a fair, safe, and secure environment to gamble in. That means they can’t rig their games, and they must protect transactions and customer data.

Needless to say, The Genie likes to keep things legit and only adds licensed UK online casinos to our lists!
