What are online casino bonuses?

Casino bonuses are offers and promotions that online casinos offer to new and existing players to keep them engaged or to sign up new ones. It’s extremely rare to find an online casino which doesn’t offer a casino bonus, especially to new players, with all casinos offering something to entice new players. Bonuses do come with set terms and conditions which players must be aware of before claiming.

How do casino bonuses work

Thumbs Up Bonus is run by a group of experienced players who’ve collectively got decades of experience in the online casino industry. When we started playing, we wished that we’d had access to sites like ours that provide honest and unbiased opinions on the different sites that exist. Instead, we had to do things the hard way, which sometimes resulted in us feeling misled or confused by what initially seemed to be excellent offers.

Thankfully, you don’t have to go through the same experience, nor do you have to spend hours searching the internet and comparing pages and pages of promotions to narrow down the best online casino bonuses that are currently available to UK players. And, because offers change on a regular basis, you won’t find yourself being sent off to find an expired promotion or a completely different casino to the one you were expecting as we’ve constantly got our fingers on the pulse and keep our Best Casino Bonuses page updated accordingly.

How bonuses work is extremely simple, bonuses are awarded automatically via sign up or by entering a casino bonus code. To claim a casino bonus all you need to do is

  1. Decide on the type of casino bonus you want (whether it’s a bonus or free spins)
  2. Find and select a casino and bonus you’re interested in
  3. Read the terms and conditions
  4. Sign up and claim bonus.

What are the Differences types of Casino Bonuses?

Understanding the different casino bonus types out there is a huge step forward in finding the right online casino bonus for you. There are 4 main casino bonus types which as both a new and existing player are able to take advantage of.

Casino Matched Deposit Bonus

A matched casino bonus offer is a common casino bonus offered by an online casino. This is simply a matched cash bonus into the players account depending on how much the player deposits plus the limits set by the casino. For example, the bonus offer offered by the casino is “100% Matched Bonus Up to £100”. What this means is that 100% of what is deposited (£100 maximum deposit) at the online casino is awarded to the player. This means if the player deposits £75, the player is awarded another £75 into their casino account. Giving the player £140 to play with.

Deposit casino bonus

This type of online casino bonus is slightly different to a matched deposit casino bonus. Instead of matching the amount deposited at 100% by the player the casino offers, this bonus type awards the player a percentage of their bonus or a fixed bonus amount.

For example, the casino may offer “50% Bonus up to £100”. Which means 50% of what is deposited is awarded to the player. If the player deposits £50, the player is awarded an extra £25 into their online casino account.

Another example is “Deposit £10 get £20”. Simply enough this online casino bonus offers the player an extra £20 into their casino account of they deposit £10. Giving them £40 in total to play with.

No deposit casino bonuses

This casino bonus type does what is says on the tin. It’s simply a bonus amount or number of free spins awarded on registration only, with no deposit needed from the player and winnings can be withdrawn,

It’s important to remember that the terms and condition of this promotion set out exactly how this type of casino bonus can be used.

Free Spins on Slots bonuses

This type of online casino bonus relates only to slot games. It’s simply a free number of spins on a specific or selection of slot games. This can be awarded to the player as a deposit casino bonus, for example, a “deposit £10 get 20 Free Spins” offer which gives the player 20 free spins on top of their deposit amount.

Or as a new deposit bonus, which awards the player a number of free spins on registration

Terms and conditions on all bonuses

The online casino bonus types offered by online casinos all have terms and conditions set which govern exactly how the promotion will work, how to opt-in and how the bonus is claimed. It’s extremely important you understand these before accepting any offer, as wagering, game contribution and withdrawal terms apply. If you need more information on what to look out for regarding online casino bonus terms and conditions check out our terms and conditions guide. Or if you want to understand wager requirements, our guide to wager requirements will help.

How to exploit online casino bonuses

To exploit an online casino bonus, one must understand the bonuses wagering requirements, redeeming games and house edge. All of which are located with the terms and conditions.

Finding the best online casino bonus with low or no wager requirements and available o games with high house edge (also known as RTP) is the only way to exploit casino bonuses.

Are there Any Strings Attached to the Online Bonuses?

Provided that you read the terms and conditions of every bonus promotion prior to claiming, anything that you perceive to be an issue will be identified, and you can always choose to walk away and look at another offer. The main risk is that bonuses don’t guarantee that you’ll win any money, but that’s the nature of online gambling – you can’t win all the time. In our experience, the most important factors to be aware of when reading Ts and Cs are:

  1. Is there a limit on how much you can win with your bonus?
  2. What are the wagering requirements?
  3. How long before your bonus and/or winnings expire?
  4. What kind of games can you play to meet the wagering requirements?

Reputable online casinos will mention all of this information in their offer’s terms and conditions, so it’s well worth taking the time to read them.

Are casino bonuses worth it?

Whether it’s a sign up, no deposit or free spins casino bonus, casino bonuses are always worth taking. you’re not going to walk away with a big win 100% of the time. But, you can use online casinos to your advantage by making sure that you claim as many membership perks as possible. And, the easiest and often quickest way to do this is by helping yourself to the best casino bonuses on the market.
