In online gaming, there are plenty of benefits that keep players locked in. Many of which come in the form of bonuses and promotions.

However, not every bonus is worth claiming. Some give you the boost you need, but others make it hard to withdraw your winnings. And it's not because of bad luck, but because the terms are designed that way from the start.

What are the biggest red flags in casino promotions?

CasinoWow takes you through the most common red flags in casino bonuses, what good terms actually look like, and a quick checklist for deciding whether an offer is worth claiming.

8 casino bonus traps

Before you claim a promotion, you need to be aware of the red flags to look for. By spotting these, you can easily determine which promotions offer a boost and which will hold you back.

Hidden & unrealistic wagering requirements

One of the first red flags in casino promotions is hidden and unrealistic wagering requirements. Some promotions may look great, but come with wagering requirements that are simply too high to ever reach. These can range between 60x and 100x or more.

These types of promotions are not practical as it becomes nearly impossible to clear the requirements. At the end of the day, the playthrough requirements strip away the majority of the bonus value.

This is especially important when the wagering is applied to both the bonus and deposit amount. As it is a lot heavier, new players often fall for the face value rather than the actual value of the offer.

Ultimately, high wagering requirements keep your winnings locked away and make the withdrawal process much more complicated than it needs to be.

Maximum cashout restrictions

Many promotional offers have a maximum cash-out restriction. This means that there’s only a certain amount you get to withdraw from the offer. This is quite common in no deposit bonuses. The casino will offer a reward, but at the same time, cap the max withdrawal amount. Generally, it is a relatively small amount, of anything from €10 to €100.

While the offer itself may seem good, the cap on withdrawals can really break your speed. Think about it, if you hit the jackpot but you’re bound to a max withdrawal limit, it can cause great frustration.

It’s important to always check for maximum withdrawal limit clauses in casino promotions before you opt in.

Short expiry periods

Most casino bonuses will have an expiry date. In general, this ranges from 7 days to 30 days in legit online casinos, depending on the promotion. However, there are some offers that have extremely short expiry periods. These casinos expect you to claim the offer and meet the wagering requirements within 24-72 hours.

These types of promotions rush the process, increase the pressure, and make it almost impossible to complete the requirements fairly. It’s a lose-lose offer for the majority of players.

When you are rushing to meet the requirements, it can lead to hasty decisions that carry no benefit. Players who have fallen into this trap have said that promotions with short expiry dates put a lot of pressure on them and cause disappointment.

Restricted games

Promotional terms and conditions often include game limitations. For many of these offers, it’s often high RTP or low-volatility games that are excluded from bonus play.

These restrictions not only limit your choices but also restrict your chances of winning. On top of that, it might even make it more difficult to meet the wagering requirements. The worst part is that it often includes games that punters love to play.

With every offer, you always need to go through the terms to see which specific games are excluded. Sometimes it will be an entire game type, and other times it will be specific slots and games listed by name.

Low contribution percentages

When it comes to completing wagering requirements, slot games often count towards the contribution, but for many other games, like table games, there are restrictions in play. Or if the games are allowed, they contribute very little to the contribution percentages.

These restrictions cut down your choice of games. For avid table game or live casino players, this can easily become a frustration, keeping you from playing games you’d most often choose first.

Instead, this forces players to opt for games they don’t normally play in an effort to meet the terms and conditions of the offer.

Withdraw delays & verification issues

Many platforms, especially unlicensed operators, tend to delay withdrawals whenever they can. They do this by insisting on heavy KYC verification checks and repeated document requests. The process is stretched out and frustrating. It’s designed this way to discourage withdrawals, and may lead to your funds being trapped for weeks.

For this reason, it’s best to check the terms beforehand and read player reviews or feedback on forums. Ultimately, the best thing you can do is opt for licensed and regulated casinos.

These sites have limitations in place, but withdrawals are processed within a couple of hours to 3 days max. There are also protections in place that give you something to fall back on when the casino is not acting according to the regulatory requirements.

Bonus abuse clauses

Casino operators have gotten smart in the wording of their promotional terms. Many will have vague terms in place that state irregular play allows the casino to confiscate your winnings. They can do so without any clear explanation of why.

At CasinoWow, we thoroughly review casino platforms and their terms and conditions. Platforms with unclear or missing terms are added to our CasinoWow blacklist of casinos you should avoid. If you’re not sure if a platform is trustworthy, we recommend checking our list of casinos filled with red flags.

Then, there's the other side of players who abuse casino bonuses, which could rightfully lead to action being taken against them. Bonus abuse is not always fraudulent, i.e., creating multiple accounts or bonus hunting, but it still goes against casino etiquette.

It’s best to stick to the rules and play at casinos that have clear, detailed terms and conditions that are easy to access and understand.

Auto opt-in promotions

The final red flag to watch out for is auto-opt-in promotions. These are not promotions you need to opt in for, they automatically apply on deposit, whether you want it or not. It’s a crafty way to lock in your funds and require more playthrough before withdrawal is possible.

As an online casino player, you may not always want a promotional offer. Sometimes you want to make a straightforward deposit, play your favourite games without restrictions, and withdraw your winnings without delay or additional requirements.

Auto opt-in promotions are sneaky and will restrict your ability to withdraw your funds, whether you wanted a bonus or not. This is why it’s important to check the casino promotions and whether they are optional before you think about making a deposit.

What good bonus terms look like

While red flags are important to identify, there are also green flags you need to be aware of. Spotting green flags in promotional offers makes it easier to get your hands on fair promotions that benefit your gameplay.

Wagering requirements: Check promotions with a wagering requirement of under 35x that applies to the bonus only.
Expiry period: Opt for offers that expire within 30 or more days. This gives you enough time to meet the wagering requirements without getting reckless or hasty in your decisions.
Little to no withdrawal cap: Ideally, you want to claim promotions that have no restrictions on withdrawals. Meaning you get to keep all your winnings.
Transparent terms: Check for offers with easy-to-understand conditions written in plain language rather than complex terms.
Game contributions: Promotions that allow table game and live dealer contributions even at reduced rates add flexibility and make it more fun for all types of players.
Max bet: Most terms include max bet rules. The standard maximum bet rules don’t restrict normal play. Check for max wagers of up to €10.

How to check whether a promotion is worth claiming

When you’re ready to claim a casino bonus, there are a few things you need to consider first. Here’s how to check if a promotion is beneficial for you:

Read the terms and conditions

Always go through the bonus terms and conditions before you even consider claiming an offer. By reading the terms, you will have a better understanding of what the promotion has available and what it requires from you.

Assess the wagering requirements

Go through the terms and check for the wagering requirements. Ideally, you want to claim offers with lower wagering requirements that can easily be met. Really understand how many times you will be required to play through the bonus before withdrawals of winnings will be allowed.

Check for hidden fees and restrictions

Don’t skim over the terms. Read it thoroughly to check for any hidden fees or restrictions, as these can easily affect the overall value of the promotion.

For example, if you prefer playing table games or live casino games, check the contribution rates. Or if you are more of a slot player, check which titles are excluded.
