What are the main types of bonuses?

UK online casino websites will offer you such bonuses:

casino no deposit bonus;
welcome bonus;
free spins;
deposit bonuses;
cashback;
other bonuses.

Follow this guide to learn more about each type of bonuses.

Casino no deposit bonus

Lots of gamblers search for the opportunity to play games for real money without having to replenish their account. That’s exactly what this reward is about. You can gamble online with no deposit required and you’ll still be able to get wins and successfully withdraw them.

The prize is usually offered when you register at online casino. In this case it’s also called sign up bonus. Everything you need to do to receive it is to create an account. In most cases you’ll have to use a special bonus code in the registration form to claim the gift.

Signup bonus isn’t big. It provides a small amount of:

free spins on registration;
free cash;
free bingo valid cards;
free chips for table games.

Casino no deposit bonus can also be provided as a prize in lotteries or tournaments and as a loyalty program gift for reaching the next VIP level. Note that no deposit wins are usually capped by a certain money amount. In most cases its 50 or 100 pounds.

Welcome bonus

Welcome bonus is a prize offered to all the new players. It often has several parts and consists of 1 – 6 deposit bonuses. To get every reward you should make a qualifying deposit. The casino will match your top-up and provide 25% – 400% more funds. You’ll also be able to receive free spins with one or a few deposit bonuses. They’re usually provided only for certain games. It can be Microgaming slot machines, for example.

Welcome bonus has limited validity and you have to claim all the parts of this prize within a certain time period set in Terms & Conditions. Bonus codes may be required to claim every new bonus.

Free spins

This prize can be used only in slots. It may be provided as a part of different bonuses. New casino users have opportunity to get free spins no deposit 2021 prize or welcome bonus free spins. The reward may also be a part of regular/special promotion or a loyalty gift from online casino. As many other bonuses, free spins have limited validity and they should be used within a predetermined time period.

To use free spins just start playing any qualifying slot machine. You’ll spin the reels and get real-money prizes without betting your own funds.

Deposit bonuses

Deposit bonuses offer you extra money when you replenish your account. They’re offered as regular and special promotions, a part of loyalty program, prize in lottery or tournament etc. Such prizes are used by casino websites to keep players engaged.

If you claim a deposit bonus, you’ll receive extra funds to your account. The prize will 25% – 100% match your top up and even more. Free spins may also be provided. A bonus code may be required to join the promotion.

Cashback

Cashback is a type of casino bonus that allows you to receive a certain refund in case of losses. It means that you’ll get back a part of funds you’ve spent on bets as bonus money. Cashback may be offered as a weekly or monthly prize. It’s often provided as special promotion or a prize in VIP program. You’ll be able to get back up to 50% of your net losses depending on the casino you play at.

In many cases this reward is absolutely cashable and doesn’t require wagering. Still, you should always check bonus policy to know it for sure.

Other bonuses

There are a few more bonuses you may receive playing at UK online casinos. One of them is a preferred payment system bonus. It’s provided when you replenish your account using a certain payment method. This prize usually comes together with the first deposit bonus, but it has different wagering requirements and limits.

Another prize you can get from gambling site is a mobile bonus. This reward is offered to players who install casino software on their smartphone or tablet. The prize isn’t big, but it’s provided without any deposit. You’ll be able to receive free spins, free cash or chips for table games.

What are wagering requirements?

Almost any casino bonus has wagering requirement. It means that you have to make a certain amount of bets in qualifying games before you’ll be able to claim withdrawals from bonus wins. For example, if your bonus is 100 GBP and the wagering requirement is x35, then you’ll have to play through 3500 GBP.

Note that different games have different wagering contribution. For slot machines it’s usually 100%, while for table games the ratio is often 10%. It means that in table games only 10 out of 100 GBP you’ve bet will contribute for wagering purposes.

Everything works in a bit different way for free spins. In this case you have to redeem not the bonus itself, but wins that were generated by this reward.
