How do we choose the Best Casino Bonuses?

There are several things that we look at when choosing the top bonuses and promotions at online casinos. Some of the main criteria are:

1. Reputable Online Casino Operators

There are certain blacklisted casinos that you may not know about. These casinos operate with bad business practices and are often devoid of good ethics. Generally, blacklisted casinos offer very tempting bonuses, no deposit offers and high deposit match promotions, which are tied to predatory terms and conditions. Most often, their promotional offers sound too good to be true! In fact, they are, and you risk losing your deposits along with your winnings.

We ensure that none of these bad casinos are included on our lists!

You can expect reputable casinos at CasinoWow who are well regulated in a top jurisdiction, or who have a strong history of upholding their most popular bonuses and payouts without heavy penalties or other drawbacks.

In addition, we're constantly monitoring the terms and conditions of new exclusive bonuses by our partner casinos to ensure you receive fair and safe offers.

2. Fair Wagering Requirements

Almost all casino bonuses are subject to terms and conditions. We ensure that these meet the best industry standards. Usually, if a casino bonus seems too good to be true, it often is. These outlandish promos will often come with over-the-top playthrough requirements before you can draw on any wins. Even when you are able to draw, sometimes the withdrawal limits are so low that it is hardly worth the time and effort expended by yourself.

So stick to good and reputable online casino brands with clear and fair bonus wagering requirements. Some things to look for include: maximum bet allowed when using a bonus, which games count towards wagering requirements, maximum withdrawal limit and the timeframe for completing the wagering requirements.

3. Good Variety

We like to ensure that all of our players are catered for, and therefore we will search for the best offers over a broader scope of promotions. Our top 5 bonuses list often holds a potent mix of Deposit Match Bonuses, No Deposit Bonuses, Free Spins and combos of Match Bonus and Free Spins, for both regular players and VIPs.

Rest assured of our judgement and professional experience, and select top casino bonuses that are worth using to bring you hours of smiles.

Frequently Asked Questions

Are online casino bonuses worth it?

Online casino bonuses can be very beneficial, providing extra funds to play with and enhancing the overall gaming experience. However, it's important to read the terms and conditions, including wagering requirements, game restrictions, and expiry dates, to determine if the bonus is worth pursuing.

Can I claim multiple bonuses at the same time?

Most online casinos allow players to claim one bonus at a time. However, some casinos may offer multiple ongoing promotions or a loyalty program that allows you to accumulate rewards over time. Always check the casino's bonus policy to understand how and when you can claim different bonuses.

What are wagering requirements?

Wagering requirements are the conditions that players must meet before they can withdraw any winnings from a bonus. These requirements specify how many times the bonus amount (and sometimes the deposit amount) must be wagered. For instance, a 30x wagering requirement on a $100 bonus means you must bet $3,000 before you can withdraw any winnings.
