If you’re wondering what we mean by “bonuses”, it’s pretty simple. When you sign up and register with an online casino, they’ll either give you free cash (usually proportional to the amount you deposit), or free spins on the slot machines where you can win without personal investment. You can even get no deposit bonuses , which don’t require you to put any money into the casino!
Bonuses are a big part of online casino nowadays, so make sure you aren’t missing out.

Free Spins

Slots are the most popular of all online casino games in the UK. In fact, they often make up 80-90% of all games offered by a casino and free spins are one of the most desirable bonuses available.

When you play slots, you wager a certain amount on every spin; with a free spin bonus, you can play as normal but using free cash from the casino. Whatever you win can be turned into actual profit, and there’s absolutely no financial risk involved. The reason we love slots is that, with every tense pull of the lever, there is the potential to win a huge jackpot, or unlock bonus rounds within games which lead to even more bonuses.

Welcome Bonuses

If you’ve been caught by the allure of online casino but aren’t sure whether to invest, or simply can’t decide which casino to partner up with, the welcome bonus will help you decide. Basically, this is a reward: you’ve chosen a casino over all its rivals, and so you’re given some free spins or cash as a thank you.

All Slots, Guts and Casumo tend to have the best welcome bonuses for new players, so be sure to check them out first

Types of Welcome Bonus

Your bonus will usually be in the form of either: Free spins, or a matched deposit.

Free spins are for players who enjoy the thrill of gambling but aren’t willing to stake much money on the outcome. There are usually large wagering requirements (see below) and so high-rollers will tend to just bet their own money and get the profits in the bank more quickly.

Matched deposits suit the big money players better. The casino will often match your first deposit 100% for up to hundreds of pounds; for example, deposit £300 and get another £300 free. For your more conservative players, the free spins may be more enticing.

Wagering Requirements

It’s not a “catch” per se, but welcome bonuses are usually a bit more than they seem. Basically (and this goes for all casinos), any winnings you make from free spins/matched deposits are subject to further wagering.

Say you get a bonus worth £25, and the wagering requirement is 40x: you must bet £25×40 = £1,000 before you can withdraw your winnings. If you hit a jackpot worth £10,000, you could do this in minutes; for others, it can take a great while longer. You can still win real profit from your bonuses, but you’ll have to be both patient and lucky.

There’s no out-and-out way to clear your wagering requirements quickly, but many people find betting aggressively works best. Higher risk for higher yield. You can bet on other games, too, though frequently only 25% or less of your winnings on another game will count towards your wagering requirement. With slots, it’s 100%.

Cashable vs Non-Cashable

Keep an eye on these terms when you are examining your signup bonus:

Cashable bonus – Once you have met the playthrough requirement, you can withdraw both your profits and the original bonus amount given to you by the casino. In our earlier matched deposit example that’s £300 plus your profits.

Non-cashable – Also known as “sticky” bonuses, you can only withdraw your profits; the bonus sum is removed.

No Deposit Bonuses

A lucrative no deposit bonus is the granddaddy of online casino rewards for those who are new to the industry: you give your email address, they give you free spins or cash. There’s no hidden pitfall further down the line, just a show of good faith from the casino.

If you make a profit, it may be necessary to place a nominal deposit (maybe £10) before making your first withdrawal, but the remaining profit (which could be thousands) will be yours alone. For free.

You can see why we love no deposit bonuses!

Mobile Bonuses

The last few years have been witness to a major boom in the world of mobile casino, and the app developers know that lucrative bonuses are the best way to lure us in. Since many developers lack the prestige that comes from being a big name in the industry for years, they need to offer even better rewards to gain players trust.

Bonuses are similar to those on desktop, with free spins and matched deposits making up the bulk of offers.

High Roller Bonuses

You can probably imagine what these offers involve – matched deposits for massive wads of cash. Gambling high stakes on new slots, if you can afford it, is the single most exhilarating online casino experience.

50% match up to £5,000 is a pretty common one. If you deposit £10k, then you’ll get an additional £5k in your bank immediately. Of course there are playthrough requirements like anywhere else, but several thousand extra pounds will certainly tilt the odds a little in your favour.

Others Popular Bonuses

Casinos are always inventing creative ways to rewards their players, and we’ve only looked at some of them. Let’s briefly examine a few others, while we have your attention.

Monthly Reloads

A reload bonus is one where a percentage (often 50-150%) of your previous deposit can be claimed back, usually after one month. This encourages players to make high deposits to improve their reload bonuses, which can come in very handy if you’re having a tough time on the reels.

Refer a Friend

Extremely simple: whenever you invite a friend and they sign up and make a deposit, using a special link, your account will be credited with a sum of money, often £50 or so. This can be used to make a profit like any other bonus, subject to wagering requirements.

Preferred Payment

Casinos want to avoid paying hefty transaction fees as much as you do, and they usually have payment methods they’d prefer you to use. A preferred payment bonus rewards you simply for using the casino’s favourite method – bargain!


Online casino bonuses have become an integral part of the industry over the past ten years, and they are only becoming more lucrative as providers attempt to out-do one another. There are incredible success stories out there of players winning huge progressive jackpots from simple free spins, so don’t ever discount a good-looking bonus: it could change your life.
