Reading our detailed online casino guides is a great way to boost your knowledge, particularly when it comes to understanding bonuses. This will help you to make wiser choices and find the best value bonus options, rather than flying blind and not getting any benefits.

Casino Bonus Regulations and Compliance

We only recommend playing at safe and legitimate online casinos, licensed and regulated by the UK Gambling Commission (UKGC). This is important because in the British casino market, gambling operators must also comply with the Licence Conditions and Codes of Practice (LCCP). This includes strict guidelines for casino bonuses and rewards.

  • MGA
  • eCOGRA

Casino Bonus Tip:

Casino sites must publish bonus terms and make them readily available to players. This is a regulatory requirement of the UKGC, and in my opinion, you should always read and understand bonus terms and conditions before proceeding.

Online Casino Bonus Types Explained

Online casinos offer a wide variety of bonuses and incentives, designed to both attract and reward players. However, there’s often strings attached in the small print, which means you should always read the terms and conditions with care.

Below is a table outlining the most common types of online casino bonuses, highlighting what they offer and what you should check before claiming. Understanding these details can help to maximise your benefits and avoid surprises, so it’s worth becoming familiar with these terms.

Bonus Type What the Casino Offers What You Should Check
Welcome Bonus offered to new players, usually when signing up or making their first deposit. Check bonus terms and conditions, wagering requirements, and eligible games before claiming.
Deposit Match The online casino matches a percentage of the player’s deposit (EG: 100% up to £200). Ensure you understand the deposit match percentage, maximum bonus amounts, and wagering terms.
No Deposit Usually offered as free spins on slots or small bonus funds credit. Be aware that wagering requirements and gaming options are restrictive, limiting any chances of keeping what you win.
Free Spins Players receive a bonus number of extra spins for slot games. Free spins are usually tied to specific slots, so check which games you can play, and if you can withdraw any winnings.
Reload Bonus for existing players who make additional deposits. Confirm the bonus percentage, wagering conditions, and expiry date for the offer.
Loyalty Rewards or points for long-term and frequent players. Can be redeemed for bonuses or gifts. Understand how rewards or points are earned, redeemed, and if they expire. Read the loyalty scheme terms and conditions.
Cashback Offered as a percentage of losses refunded to the player, over specific periods of time. Check if the cashback is real money, credited as bonus funds that can’t be withdrawn, and has wagering conditions attached.
Periodical Presented as daily, weekly, monthly, and seasonal bonus offers. Be aware of the validity period for the bonus offer, wagering requirements, and eligible games.
Payment Method Bonuses offered as incentives to use specific payment methods for deposits. Confirm which payment methods are available, plus any deposit and withdrawal restrictions that may apply.
Prize Draws Players can enter random draws for money, bonuses, free spins, or physical prizes. Verify the entry requirements, prize details and claim deadlines, read the terms and conditions.
Account Verification Bonus offered for verifying identity via email, phone, or KYC document submission. Ensure that all submitted documents meet the online casino requirements, check the terms and conditions.
Referral Offered in exchange for recommending the casino site to your friends. Be aware that your friends will need to deposit funds, before you or they receive any referral benefits.
Wager Free Quite a rare bonus with no wagering requirements attached. Confirm that winnings can be withdrawn without any restrictions, read the terms and conditions for betting limits or game restrictions.
Time-Limited Short-term promotions available for specific periods of time. Use this bonus before the expiry date, and check for any specific playthrough requirements.
Mobile Bonuses exclusively available to players using the casino mobile app. Confirm the bonus only applies to the casino mobile app users, check for compatible devices, and read the terms.

Some bonus offers can have different names, but offer the same kind of deal. For example, while Free Spins is often the most popular term used, this offer can be known as Extra Spins or Bonus Spins at some online casinos. Likewise, you may see a Welcome Bonus called Sign-Up Bonus or New Player Bonus instead.

Remember: It’s not obligatory to accept any casino bonus offer. You can opt out if you wish. Always read the bonus terms and conditions, wagering requirements, and understand the playthrough contribution percentages for different types of games. For example, 100% contribution is common for slots, but table games and live casino is often much less.

No Deposit Bonuses – Good Value or False Promise?

Everyone wants great deals, getting maximum benefits for minimum commitment. That’s why the idea of finding online casino no deposit bonus offers appeals to many players. But do casino sites really hand out free cash or free spins to players, without you making any real money deposits?

While it may seem too good to be true, some casinos do have legitimate no deposit bonus promotions. However, beyond the opportunity to play a selection of casino games without depositing first, be aware of the rigid limitations you may encounter:

Casino Bonus Tip:

In my experience, no deposit bonuses rarely provide the opportunity to keep what you win, so the chance to profit from supposedly free cash or free spins is practically zero. After all, casinos are in the business of making money, they’re not charities.

Conclusion

Now that we’ve shown you our selection of top online casino bonuses, explaining what they mean and what you should look out for, you should be able to choose the benefits that best suit your own preferences.

Take your time choosing and avoid grabbing the first bonus offer that catches your eye. Look for bonuses that offer genuine value, based on your gaming activities. Remember that it’s not obligatory to accept any bonus offer, so you can always refuse if you don’t like the deal, and carry on playing with real money at your favourite online casinos.

Online casino bonuses can be a great way to enjoy extra benefits. But always check if the bonus fits your own gaming preferences. Do this before you choose to accept any offer or promotion.

Frequently Asked Questions

We know that our readers enjoy looking for great value online casino bonus deal. That’s why we’ve listed some of the most popular questions below, featuring answers from our casino bonus experts.

What is an online casino bonus?

Online casino bonuses are promotional offers. The main goal of a casino bonus is to provide extra playing funds or incentives, aimed at encouraging players to sign up, deposit, and continue playing. Nevertheless, each type of bonus has its own terms and conditions, so it’s essential to read the fine print before claiming one.

How do free spins work?

Free spins are a type of online casino bonus that allows players to spin the reels of a slot game, without using their own money. They are typically offered as part of a welcome bonus or ongoing promotions, often tied to eligible games, such as the most popular or newest slots. Be aware that you should check the wagering limits, maximum winnings limit, plus the time limits for this kind of offer.

What are wagering requirements?

Also known as playthrough or turnover, wagering requirements are conditions set by online casinos. These determine how many times a player must bet their bonus or winnings from a bonus, before they can withdraw funds. They are usually expressed by a multiplier such as x20 or x35, for example, indicating that you must wager the bonus amount 20 or 35 times before withdrawing.
