Checklist to Help you Choose the Right Casino Bonus

Before choosing your "reward" upon your choice of casino and signing up to it, make sure the offer's something you're happy with, and get value from. We're not just talking about the monetary value here, but the little details that could make or break a good experience.

What to look for when picking a welcome bonus offer:

  • License: The casino has to be licensed and regulated by one or more of the following regulatory bodies; Malta Gaming Authority (EU) Spelinspektionen (Sweden), Danish Gambling Authority (Denmark), UK Gambling Commission (UK)
  • Amount: can you afford to take max advantage of the bonus amount? If no, then go for a lower amount
  • Wagering: make sure to check the terms of wagering for the promotion
  • Games: Make sure that the casino offers the type of games you're looking for (here's a difference between live casinos, vs. one that specializes in online slots)

We've already made sure to list you the best casino bonuses available at this time. We're sure any number of these will be a good fit for you, but ultimately the quality of your experience is the one thing that matters the most - and that depends entirely on your own style and preferences. 

Just keep in mind how you'd act if given a choice when buying something (anything really) with your own money. If there wasn't a difference in the pricing with regards to the quality, what would you choose? 

  1. Superior
  2. Outstanding
  3. Standard

We're guessing the first one. After all, gambling isn't a form of income or a way to earn money - but entertainment, and the quality of that shouldn't be any lesser than the very best. Please remember to gamble responsibly. 

Learn More About the Different Types of Casino Bonuses

Bonuses are essential rewards casinos give you for signing up and depositing money into your player account.  Cutting a long story short; standard offers gives you extra money to play with by adding more funds to your player balance. 

Deposit Bonuses

The most common type being the "first deposit" one, also known as a "match bonus". This type is also the easiest one to figure. The casino matches your deposit with a certain percentage up to the max value of the promotion, adding it to your player balance. 

If the offer is a 100% bonus, the player will start with double their deposit. If it's a 200% bonus they'll start with triple their deposit and so on.

With more to play with, you have more playtime, (and a bigger chance of hitting a big win). Or, you can play with bigger bets than you'd normally do.

Common for all casino bonuses is that the amount needs to be wagered ex-amount of times before cashing out. E.g. a €50 bonus with a 40x wagering requirement must wager €2.000 before the balance can be cashed out. 

The best casino bonuses are those that strike a good balance when it comes to the amount and the wagering requirements. 

This requirement is there to ensure that the player takes the bonus with the intention to play, and not just to cash out free money.

Deposit bonuses are mostly the "cashable" type. They're widely considered to be the best casino bonuses available. There are, however, also other types on offer. 

The different types of deposit bonuses are:

  • Cashable
    The most common casino bonus type is the cashable one. Once the wagering requirements of the bonus have been fulfilled, both the deposit, winnings and bonus are free to cash out.
  • Sticky
    The Sticky bonus is exactly like the cashable bonus but with one key difference - the bonus itself cannot be cashed out. Once a player fulfils wagering requirements, they are allowed to cash out their deposit and winnings, but not the bonus. When a player makes a withdrawal that includes a sticky bonus, the bonus is generally deducted from the withdrawal sum.
  • Post-wager
    Post-wager deposit offers differ from the cashable and sticky versions in that they are credited only after the player has wagered their deposit a certain amount of times. Some players prefer this as it allows them to cash out whenever they want (as the deposit is not tied to wagering requirements), but most prefer the cashable bonuses as they allow a bigger balance to be played immediately after deposit.

No-deposit Bonuses

The no deposit bonuses don't require you to deposit to receive them. It's the perfect opportunity for you to take the casino for a … spin - before depositing.  No-deposit bonuses are great for getting a feel for the casino you're testing out. As an added bonus in itself, you also stand a chance of winning money while doing it. Do however note that almost all bonuses that don't require a deposit carry both relatively high wagering requirements as well as having a max cashout - e.g €50 euro.

You should not that, however, some no deposit offers comes with real money deposit requirements before withdrawing the funds. That's why you need to make sure to always read the casino's terms and conditions.

Free spins Bonuses

These are mini-bonuses; free game rounds on video slots which you needn't pay for. Any winnings are yours for the taking. Meaning that those 20 spins are on the house, and whatever you win you get to keep. 

The best casino bonuses when it comes to free spins are by default those without wagering requirements. Why? Your winnings don't need wagering before being able to cash them out. That is, provided you meet the minimum withdrawal amount of course. 

While the winnings from these free spins bonuses often carry wagering requirements, they have the benefit that you can often choose when to play them, which means that they won't tie in with your deposit until you choose to use them. If you score a big win with your own deposit, you can cash these winnings out and then play the free spins for a chance to win more.

Free spins can be both of the deposit (e.g. Deposit €20 and get 50 extra free spins) and no-deposit type (Join our casino today and get 20 free spins to try us out).
