Unique Online Casinos Testing Methods

Evaluating online casinos is a tough task that has to be accompanied by a precise and reliable procedure. Our unique methodology ensures that our reviews remain objective and honest. This method produces our reliable and trusted online casino list.

We separate these gaming options based on certain factors as regards their game collections, banking options, security, and game providers. We also review their customer support options and responsible gaming tools to confirm that they have options to protect their customers.

As part of our attempt to protect you from unreliable online casinos, we have to include some gaming sites in our blacklist online casino. The blacklisted online casinos are not always illegal or scam gaming sites. Sometimes, they are just regular casino sites that don’t meet essential wagering requirements.

In our experience, casinos with ratings less than 40, poor data protection, and unverifiable gaming licenses usually end up on the blacklist. Let’s take a quick look at some practices that may get an online casino blacklisted.

Issues with Security

Most blacklisted casinos need more security. They don’t take steps to protect their customers' private information and don’t have valid security encryption. Our research shows that most unreliable online casinos are data farms for scammers to steal players' information, such as their full names, addresses, and banking information. These casino sites also avoid government regulation and refuse to get gaming licenses from international or local gaming authorities. They prefer to operate unchecked to avoid complying with existing gaming regulations.

Issues with Casino Bonuses

Casino bonuses and promotions are designed to pull in and reward players. However, they sometimes become hidden pitfalls against such players. Hence, players feel frustrated in their gambling adventure because of unclear terms and conditions.

Some casinos intentionally use vague and misleading terms so players don’t understand them. Others hide this information, leaving their customers in the dark regarding bonuses.  At SlotsUp, we ensure thorough checks are performed to pick out brands that practice this unhealthy practice.

Issues With Terms and Conditions

Casino terms and conditions should be clear and understandable. They should not include hidden meanings that can affect a player’s voyage. Online casinos should also provide notices making changes to their terms and conditions. Some blacklisted casinos fail to send notices or popups when important gaming conditions are changed. These subtle changes to the casino terms and conditions make it impossible for players to obey them, impacting their gaming experiences. This scam is enough for us to include any casino on our online casino blacklist for cheating their players.

Issues with Payments

Players need to make their deposits and withdrawals through safe, reliable, and fair channels. Using slow payment methods or taking too long to process deposits and payouts makes a casino appear unreliable and can easily ruin the gaming experience.

The availability of a few payment options is a red flag, especially when they are not recognized or popular. It is best to avoid potential risks and avoid casinos offering limited and obscure banking channels.

Issues with Customer Care

Customers frequently need help to navigate the games and other services; this is where customer care comes in. When players get slow responses, they get burned out. Hence, they give the website a poor review. Players want instant responses to their queries. They want 24/7 chat and email responses. They also prefer hotlines where they can speak with the customer support agent. Casinos that don’t have these services may end up on our blacklist.

Issues with Gaming

Players who explore these sites are often left frustrated. Issues like rigged games and uncertified software can affect the players’ trust.

These casinos are unreliable because of poor game selection, bad software, slow/laggy performance, and partnerships with unreliable software developers. And these also raise real concerns about their reliability and quality.

Reputation Issues In Blacklisted Casino Sites

All blacklisted casinos have these issues. They tend to get attention for unfair gameplay, no licensing, delayed payouts, etc. At SlotsUp, our experts stay on the market, analyze player reviews and put our well-detailed reviews of these brands. These reviews are constantly visited to ensure they are always relevant.

Our list of blacklisted online casinos helps players identify those to avoid, yet many still choose to play at these risky options. While we cannot stop players from placing their bets on such sites, knowing the consequences is best. Here are some of the risks associated with playing at a blacklisted website:

• Delayed or denied payouts

• Confiscation of winnings

• Lack of player protection when playing at an unlicensed casino

• Poor customer service

In our experience, many online casinos offer their services without due process. This does not make them scams, but it can affect their services. The poor services on these sites may result in poor ratings from unsatisfied players and blacklists by reviewers and regulatory bodies. However, these blacklisted casinos can redeem themselves by improving their services, getting gaming licenses, and offering quality games by certified software developers. This attempt to redeem itself may take a while, but it would be sufficient to remove the casino from the blacklist.

Despite the growing number of scams and rogue online casinos, there are still many quality options available. We keep a detailed list of the best online casinos to help players find reliable casino options. We use different factors to test the gaming experience, customer support, and payment options in these casinos before adding them to our list.
