Getting Acquainted With Bonuses

If an online casino bonus offer seems too good to be true, it's worth examining the logic behind them. In case you haven't noticed there are more than a hundred licensed gambling sites vying for your business in Britain. Casinos are well aware that competing options are just a click or tap away. In order to attract players and keep them happy, they do dole out big bonuses.

Most Popular Bonuses

Welcome Bonuses - Casinos will give you free cash on top of your initial deposit as a welcome.


No Deposit Bonuses - Players can claim free cash without a deposit. Although you'll usually only get a few pounds or free spins, you can win real cash.


Reload Bonuses These are available to existing players. You'll generally get extra cash when you deposit.


Loyalty Rewards - Some casinos offer a loyalty program to reward frequent players. While there are many benefits such as prize draws, you can rack up points which can be redeemed for extra cash or free play bets.

Online casino bonus offers beat just about anything you'll find when gambling offline. When you visit a site for the first time, you can take advantage of a sign up or welcome bonus. These usually take on the form of a match bonus, which will give you extra cash when you fund your account. For example, you might find a 100% deposit bonus up to 1,000. That means the casino will double the amount of your deposit up to a specified limit. When playing at a site, UK players can also find no deposit online casino bonuses that give you free spins or a little cash to play with even if you don't feel like opening your wallet.

Online casino bonuses make you a winner before your first hand or spin of the reels.

You should always aim to claim the best online casino bonus possible, especially since you can use your free money to win even more. Fortunately, we have already compared every licensed gambling site available to British players, with the aim of uncovering phenomenal promos, bonuses, and rewards. All you have to do is claim yours by visiting any of the recommendations on this page.

Frequently Asked Questions

How do deposit bonuses work?

When you claim a deposit bonus, you'll get extra cash on top of the money you add to your bankroll. For example, you might find a 100% deposit bonus that will double the amount of your initial deposit. Find out more in our guide to how bonuses work.

Can I cash out my bonus?

While bonuses are effectively free money, you can't withdraw your complimentary cash immediately. At an online casino, UK players must satisfy wagering requirements before cashing out. In other words, you'll need to play a set number of games first.

Do I have to be a new player to claim a bonus?

Although welcome bonuses are generally reserved for new players, the free cash doesn't have to end after your first deposit at an online casino. UK casino fans can take advantage of reload bonuses, promotions, and loyalty rewards.

Can I claim bonuses on my smartphone or tablet?

It doesn't make a difference how you choose to access online casinos. UK sites will let you play and get a casino bonus on any iPad, iPhone, Windows Phone, Microsoft Surface, Android tablet or smartphone.

How do I find a great site with a big bonus?

Our gambling experts have tested and compared every licensed gambling site in the UK. If you're ready to claim free cash from a fantastic casino just visit any of the top-rated sites we've collected on this page.
