What is a casino bonus?

So what exactly is a casino bonus? To put it simply – Casino Bonuses are rewards that the casino credits at various stages. Such as signing up or when you first deposit at a casino. The most common types of casino bonuses are welcome bonuses, which you will receive upon registering at an online casino or once you make your first deposit. Welcome bonuses are optional, however, the majority of players prefer playing with a bigger bankroll. Which makes good welcome bonuses highly sought after. Besides welcome bonuses, there are various types of other bonuses, such as reload bonuses, loyalty offers, weekly and seasonal casino bonus campaigns.

Online casino bonuses are a great incentive for players to make a deposit and have a bigger bankroll, therefore playing longer at a casino and having increased chances of hitting a big win. When choosing which is the best online casino bonus for you, it’s important to pay attention to the terms and conditions to make sure you know what you are signing up for.

Types of online casino bonuses

Since there are so many kinds of online casino bonuses, it can be easy to get lost in all the terminology. Especially if you are a beginner player. Don’t worry, the Solid Casinos team is here to break down the most popular types of online casino bonuses, so you know what to look out for!

Welcome Bonus

Welcome bonuses are vital for casinos to attract new players. Nowadays the competition between online casinos is fierce, so it’s important to have a great welcome offer to incentivize players to sign up and make a deposit. There are two kinds of welcome bonuses – Deposit offers and no deposit bonuses, that you can receive upon registration.

Deposit Bonus

As we’ve already mentioned – this is the most common type of online casino bonus. A deposit bonus requires you to make a deposit at the casino in order to claim the bonus. The amount you can receive will depend on the specific offer, as well as how much you are depositing.

No Deposit Bonus

No deposit bonuses are usually awarded upon registration at an online casino. It’s a great way to explore what the casino has to offer without putting in any real money, so it’s risk-free. Some casinos will also offer no deposit bonuses as seasonal promotions if you are subscribed to their newsletters.

Cashback Bonus

A cashback bonus will give you a percentage of the money that you have lost back to you. Some casinos will give cashback in the form of bonus money, while others will credit real money back to your account. It’s a great way to get back some of your losses and have another chance to get that big win!

Free Spins Bonus

Some casinos will offer free spins on a certain slot game. The winnings of the free spins are usually added to your account as bonus money, that you can then play on other slot games. There are some Free Spins offers that are wager-free as well, so always pay attention to the terms and conditions of the specific offer.

Match Bonus

Match Bonuses are arguably the most common types of casino bonuses you will encounter. The size of the bonus you can receive is based on the amount of real money that you deposit. For example, a 100% up to $100 bonus will give you a bonus dollar for every dollar that you deposit – up to $100. Match bonuses are a great way to boost your bankroll, so you have more to play with.

Reload Bonus

Reload bonuses are offered to existing players at a casino. Once you are registered at an online casino and have subscribed to the newsletters, you will receive reload bonuses right to your mailbox. You will have to make a deposit to claim a reload bonus and it can consist of a match bonus, as well as free spins or even cashback.

Refer-a-Friend Bonus

Almost all casinos will have a refer a friend bonus that they offer. If you find a casino that you really like, you can share it with a friend – both you and your friend will receive a special offer. Usually it’s required for your friend to make a first deposit for the bonus to be awarded to your casino account. Refer-a-friend bonuses are a great way for casinos to expand their player base, especially for New Casinos.

Loyalty Bonus / VIP Bonus

Loyalty or VIP Bonuses are only offered to players that have been active at an online casino and meet their VIP criteria. Not all casinos offer a loyalty scheme, however all the best online casinos will have one for sure! There are usually multiple levels of loyalty schemes, which determine what bonuses you are eligible for.

High Roller Bonus

High roller bonuses are for players who are looking to make larger deposits and play with higher stakes. Some online casinos will cater to high rollers and have special bonuses. High Roller bonuses will usually have specific terms and are more favorable for high rollers. These bonuses are for experience players only.

How do online casino bonuses work?

If you are a new online casino player, it can get confusing when it comes to casino bonuses. All casino bonuses come with terms and conditions attached to them, which you have to follow in order to claim the bonus. Not to mention, that braking the terms and conditions will invalidate your winnings. So make sure that you are aware of the terms and conditions, they are usually easily accessible on the promotion page.

Here are a few things to note, so you can feel more comfortable when choosing an online casino bonus

Deposit Requirements

Usually online casino bonuses, will require you to make a deposit, with the exception of No Deposit Bonuses. For Deposit Bonuses, the size of the bonus will always depend on the amount that you deposit. For example, if it’s a 100% Match Bonus, by depositing $20, you will receive $20 in bonus money, equalling $40 in your casino account. Always pay attention to what are the minimum and maximum deposit requirements in order to be eligible for the bonus.

Wagering Requirements

Wagering requirements tell you how much you need to bet before you can withdraw your winnings. In order for the bonus money to be converted to real money, you need to fulfil bonus wagering requirements. For example a 40x wagering requirement on a $100 bonus means that you must bet $4,000 (40 x $100 before you can withdraw your winnings. Also check which games are eligible for wagering, as usually Table Games and Live Games are either excluded or contribute less towards wagering.

Bet Limits

For most, if not all bonuses, there will be betting limits in place. Always check what is the maximum bet per spin that you can place when using an online casino bonus. For example, you might be allowed to bet a maximum of $5 per spin. This is a very standard term and even the best online casinos will have a maximum bet limit. Make sure to abide by these terms in order to have a successful withdrawal afterwards.

Win Limits

Some online casino bonuses will also have winning limits set for specific bonuses. This is especially the case when it comes to Free Spins offers or No Deposit Bonus offers. For example a specific promotion can have a term that states that you can only win $100 from Free Spins. That means that even if you won a bigger amount and met the wagering requirements, you will only be able to withdraw $100.

Time Limits

Virtually all online casino bonuses will have a set time limit attached to it. Meaning that you have to complete the wagering requirements within a set amount of time. Usually it would be something like 30 days from the time that you claimed the bonus offer. You might also encounter shorter time limits, especially when it comes to No Deposit or Free Spins offers. This information will always be available in the Terms and Conditions of the specific offer.

Excluded Games

Even the best online casinos will have a list of games that they exclude from playing with bonus money. These will usually be the most volatile games, such as NetEnt’s Dead or Alive slot. Usually it’s the same list of games that are almost always excluded from bonus play, however each casino sets their own terms and conditions, so it may differ from casino to casino. Always make sure to check which games are excluded from playing with a bonus, so you can have a successful withdrawal afterwards.

What to look out for when choosing an online casino bonus?

When it comes to online casino bonuses – it’s definitely not a one size fit’s all situation. Every player has different things that are important to them, however, there are a few things everyone should be paying attention to when deciding which online casino bonus is the best for you. Here are a few tips from the Solid Casinos team for choosing an online casino bonus.

  • Wagering Requirements should be one of the first things you look at when evaluating an online casino bonus.The smaller the number – the better! It’s much easier to complete a 30x wagering requirement than a 50x.The industry average is 40x, however it depends on a lot of factors.
  • Deposit Requirements are vital when choosing an online casino bonus. Make sure that it’s within your budget and valuable in proportion to the deposit that you are making.
  • Game Restrictions are a part of virtually any bonus. Usually Table Games and Live games are in the restricted games list when it comes to playing with bonus money. Or such games will contribute a smaller percentage towards wagering. Often excluded are also some high volatility slot games when playing with bonus money. For example the Devil’s Delight slot. This info will always be clearly displayed in the terms and conditions.
  • Match Bonus Percentage will determine how much you can claim in bonus money. The higher the percentage, the more bonus money you can receive. A 100% match bonus is very standard, but you will also see 200% and even 300% match bonuses out there!
  • Deposit Methods are another thing you need to pay attention to when claiming an online casino bonus. There are certain deposit methods that casinos will usually exclude for specific bonuses. Want to deposit using E-Wallets? Bonus promotions often exclude Skrill and Neteller, so pay attention to what the terms say.
