Online Casino Bonuses for 2021

There are so many different types of online casino bonuses that it can become very confusing to understand what you are actually getting when you join a new online casino. Why do some online casino’s offer 1200 free whilst others only offer 150 free and which offer is better? The only way to answer this question is to break up the offer into its parts and fully analyse each part of the casino bonus.

An online casino bonus can be broken up into:

Bonus Type
The bonus type is the mechanism that the bonus is awarded on, these could be free spins, deposit matches or no deposit bonuses.
Bonus Terms
The bonus terms can comprise of a number of factors including but not limited to maximum bonus amount, minimum bonus amount, deposit thresholds, deposit percentages and free spins values.
Casino Terms
These are made up of minimum withdrawal amounts, wagering requirements and miscellaneous terms that certain casinos apply that do not relate directly to the bonus in question.

Casino Bonus Types

Online casinos are constantly innovating and coming up with new types of bonuses and promotions to offer potential new customers. The majority of these innovative casino bonuses are still based on the same core bonus type we will discuss below.

Deposit Match Casino Bonuses

The most common component of of the best online casino bonuses it that of what is commonly referred to as a deposit match. This is when the casino matches all or a portion of a deposit made by a player. This “free money” is credited to the players casino bonus balance. This bonus money is made available for players to gamble with across all games at the online casino but cannot be withdrawn until wagering requirements are met, at which point the bonus money gets converted into cash money and is transferred to the players cash balance at the casino. This process can be confusing for players as bonus balances and cash balances are commonly combined in the casino interface.

Deposit match bonuses come with a variety of minor terms that potential customers should always look out for. The key terms to take not of are:

  • Casino Coupon – This is the total amount of free money available via the deposit match. The coupon can be split across multiple deposits which is common on large deposit match offers.
  • Deposit Match Percentage – This is the match percentage that the casino will cover of your deposit. The highest deposit match percentage is usually attributed to your first deposit. This percentage match is often as high as 100% and in some cases like Lucky Nugget Casino is at 150%.
  • Wagering Requirements – Wagering requirements are one of the most controversial terms that are attached to casino bonuses. Wagering requirements are the number of times you must bet your free money before being allowed to withdraw it. These numbers range from 35x to 55x depending on the program. This is a why it is imperative research the wagering requirements attached to a bonus before you deposit money at a casino.

You will often see that online casinos offer multi-deposit match welcome bonuses. This is where they offer deposit matches across your first x number of deposits with varying coupon and deposit match percentages. This allow for online casinos to advertise larger free bonus amounts and benefits players as they receive large deposit match percentages across more of their deposits. Captain Spins Casino’s welcome bonus is a good example of this where they offer 100% match percentage across your first 4 deposits with a coupon value of $/£/€ 300. This allows players to claim up to 1200 in bonus money via deposit match bonuses. The Captain Spins welcome bonus also has 260 bonus spins available to players that are credited on each of their first 4 deposits.

Free Spins Casino Bonuses

Free spins are another popular casino bonus type because they give customers the ability to play at a casino without risking their own money. You will sometimes see free spins referred to as bonus spins but they are essentially the same thing. The difference in terminology is usually determined by geographical and regulatory differences. In the UK, casino are not allowed to refer to their bonus spins as free spins as there are wagering requirements attached to the spins which under UK regulatory guidelines means that they are not free.

Free Spins are awarded to players as part of casino welcome bonuses. They can be awarded as a no deposit bonus or as part of a larger deposit match bonus. They are commonly awarded on increments of 10 of 50 free spins. Free Spins are awarded on slots that allow for low value spins which means that the potential cost to the online casino is mitigated. A rough guide to calculating the value of a free spins bonus is to divide the total number of free spins by 10. This is not always the case and a more comprehensive explanation of how to calculate the value of free spins can be found on our Free Spins Bonus Page.

The key criteria to research when determining how good a free spins casino bonus is, are:

  • Free Spins Slot – The slot machine that the free spins are awarded on. This is important as getting free spins on a boring slot aren’t really worth it. The most popular slots for free spins are Starburst or Book of Dead.
  • Number of Free Spins – This would be the number of free spins that are made available via the casino bonus.
  • Free Spins Value – The monetary value of the free spins. Some free spins are more valuable than others but in general the 10% rule can be applied.
  • Wagering Requirements – Winnings from free spins are normally subject to wagering requirements but some online casinos Like Dunder give wager free, free spins.
  • Maximum Win Limits – There is normally a maximum win limit attached to free spins. This is normally 10x the value of the free spins but should be checked at each casino.

Online Casino Bonus Terms

There are a number of terms that players should always look out for when assessing online casino bonuses. This is not a comprehensive list but it does highlight a number of key terms that players should look out for. Remember that even the best casino bonuses do come with a number of terms and conditions.

Casino Bonus Wagering Requirements

It is important that players check wagering requirements before depositing money at an online casino. The wagering requirements attached to a bonus are important for any player looking to withdraw their winning from an online casino and some casinos have what we would consider excessive wagering requirements attached to their bonuses.

Wagering requirements range from 35x to 55x. The 35x is already an imposing number before some casinos push it up to the 55x mark. If you consider that the average online slot pays out at 96%-98% we can calculate the theoretical cost is of meeting wagering requirements. If we play a slot with a low hold percentage of 98%, the play through would cost us close to 70% of our total bonus.

Bet Limits for Wagering Requirements

It is common for online casinos to limit the maximum you are allowed to bet during the period you are playing through your bonus money. This term is normally only applied on welcome bonuses and if the term is vague in the terms and conditions, you should request an official position from the casino via email.

Maximum Win Limits

This term is often applied to free spins casino bonuses and is normally a multiple of the value of the free spins. If you receive 50 free spins on Starburst as an example. The value of those 50 free spins is likely to be $/£/€ 5. A common maximum win limit on the free spins would be 10x and therefore you would be limited to winning $/£/€ 50 on your initial free spins. This win limit is not applied to any winnings after your free spins have completed.

Minimum Withdrawal Limits

All online casinos impose a minimum withdrawal limit. This is not normally a problem but for players looking to win real money and withdraw their winning from no deposit bonuses, they are often blocked from withdrawing their winnings as they are below the minimum withdrawal limits imposed by the casino. The most common minimum withdrawal limits are either $/£/€ 20 or $/£/€ 50 depending on the casino involved.
