Types of Online Casino Bonuses

Here are the main types of online casino bonus: 

  • No Deposit Bonus – You will receive bonus credits after you create a new player account.
  • No Deposit Free Spins – You will receive free spins after you create a new player account.
  • Match Bonuses – You will receive bonus credits after you make a qualifying deposit.
  • Cashback Bonuses – You will receive a percentage of your total losses as cashback over a period of time.

How to Evaluate No Deposit Bonuses

No deposit bonuses are fairly easy to evaluate. Before you claim a no deposit bonus, please ensure you have taken the following criteria into account:

Wagering Requirements

Many new players make the mistake of claiming the biggest no deposit bonus. The real trick is to claim the bonus with the lowest wagering requirements.

A terse example can illustrate why:

Bonus ValueWagering RequirementsSum-total you have to wager
Bonus #1$1010$100
Bonus #2$10050$5,000


As the table illustrates, with Bonus #1 you only have to win $100 before you can withdraw your winnings. Alternatively, you would have to wager $5,000 using your bonus if you wanted to win real money with Bonus #2.

The Eligible Games

You need to ask yourself which games you want to play. No deposit bonuses are often liberal with their selection of eligible games. However, certain games with favourable odds may face restrictions.

For example, table games such as blackjack, roulette and poker are likely to have their game contribution lowered, making it more difficult to fulfil your wagering requirements.

We can illustrate how this makes a difference using an example:

Type of GameGame ContributionMoney WonMoney Contributed to Wagering Req.
Slots100%$100$100
Table Games10%$100$10


Ultimately, under these conditions it would take you ten times longer to fulfil your wagering requirements playing on table games than it would on slots.

The Winnings Cap

While you can win real money with no deposit bonuses, you won’t be able to bankrupt the casino. The vast majority of no deposit bonuses come with a winnings cap, often set at around $100. Essentially, this means you would only be able to win up to $100 in real money using your bonus.

Our tip here is predictable: claim a no deposit bonus with a high winnings cap.

We recommend you pick a no deposit bonus with low wagering requirements and then use your credits on whichever slot has the highest Return to Player (RTP).

How to Evaluate No Deposit Free Spins

No deposit free spins require a bit of effort before you can find the best.

We’ll break down the evaluative criteria in the simplest possible way: 

The Value of Spins

Don’t be misled by no deposit free spins bonuses offering you an abundance of free spins! Usually, a single free spin is equal to the lowest possible bet on the eligible slot machine. Therefore, to work out the total value of your free spins you have to take into account how many you receive, plus the value of the minimum possible bet on the eligible slot.

Here’s an example that can illustrate the potential difference:

Number of Free SpinsMinimum Bet on Eligible SlotActual Value of Free Spins
Bonus #120$0.1$2
Bonus #2100$0.01$1

The Eligible Slots (Return to Player)

The odds of slots is measured by a percentage known as Return to Player (RTP). If a slot has an RTP of 97%, it means that for every $100 spent on the slot, it returns $97 to the player. Consequently, the higher the RTP of a slot, the more likely you’ll win.

The RTP of most slots is made public and can be discovered by Googling the slot’s name alongside the letters R-T-P. If you select a number of no deposit free spins bonuses, you can compare the RTP of the eligible slots and claim the bonus that performs best.

The Winnings Cap

Similar to regular no deposit bonuses, free spins tend to come with a winnings cap. While it will not improve your chances of winning, it would benefit you in the long term to claim free spins bonuses with high winnings caps.

Wagering Requirements

The wagering requirements work differently with free spins. Before you can know how much you have to wager before you can withdraw your winnings, you need to use your free spins.

Here are a few examples to illustrate how it works:

Number of Free SpinsFree Spins WinningsWagering RequirementsSum Total You Have to Wager
Bonus #120$1040$400
Bonus #250$520$100


As with regular no deposit bonuses, always claim the bonus with the lowest wagering requirements to have the best chance of winning.

We recommend you pick a bonus with the lowest wagering requirements, which is eligible on a slot with a high RTP. Any slot with an RTP over 96% gives you a great chance of winning.

How to Evaluate Match Bonuses

Match bonuses can be ever-so-slightly more complicated than the previous bonuses.

We’ll go over the main criteria and provide you with examples. 

Calculate the Max. Bonus Amount

An easy way to evaluate match deposit bonuses is to compare its monetary value. In some cases, it may not be self-evident which match bonus is the most valuable because it depends upon how much you are willing to deposit. .

Let’s say you are looking to make a first deposit of $150 and you have three match bonuses to choose from:

Maximum BonusPercentage MatchDeposit Required to Max BonusAfter Depositing $150
Bonus #1$200100%$200$300
Bonus #2$175150%$131.25$325
Bonus #3$30050%$600$225


As you can see from the table, the second bonus – while offering to match your deposit by a lower value – is actually the most appropriate for your budget. If you change the amount you deposit every so slightly to $200, this is no longer the case:

Maximum BonusPercentage MatchDeposit Required to Max BonusAfter Depositing $200
Bonus #1$200100%$200$400
Bonus #2$175150%$131.25$375
Bonus #3$30050%$600$300


Now that you have increased your first deposit to $200, Bonus #1 is a better option than Bonus #2, for you receive more in bonus credits for the same deposit.

Wagering Requirements

Wagering Requirements
Due to the high value of match deposit bonuses, the wagering requirements can be unreasonable. For example, let’s say you claim a match bonus worth 100% up to $2,000, and it comes with wagering requirements of 60x. When you put these figures into the following equation, you realise it’s almost impossible to win real money:

Value of Bonus ($2,000) x Wagering Requirements (60) = Sum Total ($120,000)

Unless you think you can win $120,000 before your bonus expires, you should not claim this hypothetical bonus.

The Winnings Cap

When it comes to the winnings cap, match deposit bonuses are superior to no deposit bonuses. Many do not come with a winnings cap, and when they do, it is often more generous. Nonetheless, it is still one way you can compare match deposit bonuses. Ideally, you should claim the match bonus with the highest winnings cap.

Game Contribution

Match bonuses give you the chance to play a wide variety of casino games, including table games, such as blackjack, roulette and poker. However, we do not recommend playing table games with a match bonus.

While it may seem wise to play on table games due to their favourable odds, these same games are likely to face restrictions under a term and condition entitled ‘game contribution’. Here’s a definition:

Game Contribution – The percentage of your winnings on a particular game that goes towards fulfilling the wagering requirements.

If you have not already seen it earlier in the article, the following table illustrates how ‘game contribution’ works:

Type of GameGame ContributionMoney WonWagered Amount Contributed to Wagering Req.
Slots100%$100$100
Table Games10%$100$10


Essentially, it can take you more than 10x longer to fulfil your wagering requirements playing table games than it does playing slots.

Top Tip

There are a few things to consider when claiming a match deposit bonus. We recommend you claim one without a winnings cap. Low wagering requirements are necessary if you want to have a chance of winning. Additionally, you should stick to playing a high RTP slot (please avoid all other games).

If you cannot find a perfect match deposit bonus, our advice is to just play with your own funds. The terms and conditions of these bonuses can be so unreasonable they are not worth claiming.

How to Evaluate Cash Back Bonuses

Cashback bonuses may not seem as spectacular as the other types of bonuses featured here, but we prefer them. These are ideal for any player that wants to play using their own funds. 

Type of Cashback Bonus (Losses vs Amount Wagered)

There are two types of cashback bonus, with one being self-evidently better than the other.

Here are definitions of both types:

  • Cashback on Losses – You will receive a percentage of your losses in cashback over a specified length of time.
  • Cashback on Total Bets – You will receive a percentage of all wagers in cashback over a specified length of time.

In theory, claiming a bonus with cashback on all bets is preferable to cashback for every losing bet.

Cashback Percentage

Another clear area of comparison is the cashback percentage. It may be superfluous to provide examples of why and how this makes a difference, but we shall do so anyway:

Amount WageredCashback PercentageTotal Cashback
Bonus #1$10010%$10
Bonus #2$10020%$20


As you can see, it is worth claiming the cashback bonus with the highest cashback percentage.

Expiry Date

As well as the cashback percentage, you also need to be aware of the expiry date of your cashback bonus. There is a big difference between your cashback bonus being active for a week than if it were for a month. Here’s a table that illustrates the significance of a cashback bonus’ expiry date:

Cashback PercentageAmount Wagered Per DayExpiry DateTotal Cashback
Bonus #120%$207 days$28
Bonus #210%$2028 days$56


Even with a higher cashback percentage, Bonus #1 still returns less than Bonus #2 due to its shorter expiry date.

Wagering Requirements

The phrasing of ‘cashback bonuses’ may be misleading. At the end of your cashback period, you will most likely be repaid in bonus credits rather than real cash. These credits are likely to come with wagering requirements. We recommend claiming cashback bonuses with the lowest wagering requirements.

Top Tip

Cashback bonuses are the safest type of bonus to play with due to their kinder terms and conditions. However, as always, please make sure you read the fine print.

In Summary 

As is the case with most questions, the type of bonus you should choose depends on a nuanced array of criteria. Ultimately, it comes back to what you want from a bonus, as well as other questions, such as how much you would like to deposit, which games you would like to play, and more. 

The best advice we can give to players is to claim an online casino bonus that has been evaluated by an industry professional. Claiming a bonus on NoDepositKings is your best protection against fraudulent casinos.
