Online casinos welcome bonuses

To attract new players to their website, online casinos offer them welcome bonuses. The welcome bonus you will receive can take multiple forms: deposit bonus, no deposit bonus, free spins, cash money… Discover all these kinds of bonuses just below.

Online casinos deposit bonuses

The first and more frequent kind of online casino welcome promotion are the deposit bonuses. It is also the main bonuses you will find here, on Madness Bonus: deposit bonuses on the best and more trustworthy online casinos. How does this work? It’s very simple. Deposit the amount of money you want (300€ for example), and your depositt is matched by the casino to a certain percentage and amount.

For example: deposit 300€ with a 100% up to 300€ bonus and you will start playing with 600€ in total.

As nothing comes for free, these bonuses come with betting requirements. You have to complete a wager. That means you must bet the amount of your deposit and the bonus that you received a certain amount of times. If we take the previous example (300€ deposit, 300€ bonus) with a wager x30, you have to bet 18,000€ before requesting a withdrawal.

Of course, this is just an example as every casino has wagering requirements of its own. Some casinos will give you a lot of free room in how you can play with an active bonus. Others will have very precise and restrictive rules. Always read the bonus terms and conditions before depositing. The most common betting rule is a 5€ maximum bet per spin.

No deposit bonuses: free money

No deposit bonuses are another kind of common welcome offers. Some casinos are offering you a small amount of cash you can use to discover their games. Most of the time, you will receive between 5 to 10 euros directly into your balance. Just know that in general, you are only allowed to withdraw up to 100€ from the winnings made with this free money. For more information, read the casino’s terms and conditions.

We know it can be frustrating to be limited like this, but just see this bonus as a way to discover the casino. Nothing more.

Online casinos welcome free spins

Finally, you can also receive free spins when registering on a casino. On some casinos, you receive these free spins in addition to your deposit bonus. Other times, you just receive these upon registration. Either way, always be sure to check the casino’s terms and conditions to be aware if your free spins come with specific wagering requirements.

How to find a good online casino?

Finding a good and trustworthy online casino is not easy. There are a lot of options out there, and the best is still to compare the different casinos. As we know your time is precious, we have redacted online casino reviews to help you choose the best casino.

We analysed a series of criteria to identify the best online casinos:

  • The Design and features: Madness Bonus pays a particular attention to the casino’s design and features. These points are very important for the players. A casino that looks good is instantly more trustworthy. Add to this useful features such as excellent games filters, a loyalty program progress bar or live RTP display, and you have a pretty good casino in front of you.
  • The bonuses and promotions: We can’t deny it. Bonuses and promotions are one, if not THE number one factor when it comes to choosing a casino to play on. Lucky for you, we have plenty bonuses in here! Don’t hesitate to compare them and take the one you think is the best.
  • The games library: What would be an online casino without a good games library? You might wonder: what makes a good games library? To us, a casino that has famous game providers such as Play’n GO, Pragmatic Play, Push Gaming, Quickspin, Netent or Nolimit City is in this category. Of course, it should also feature Evolution Gaming’s Live casino games.
  • The VIP and loyalty programs: Attracting new players with appealing offers is one thing, making them loyal is something else. Some casinos are better than others in this. Don’t hesitate to check how a casino rewards his players through its loyalty and VIP programs. It could help you choose one casino over an other. Cashback, deposit bonuses, free spins, free cash… Casinos reward their loyal players in many different ways.
  • The deposit and withdrawal methods: While credit card is the most common deposit method, there are other options to credit your player account. Among these are e-wallets, cryptocurrencies, bank transfer… Each casino has a different approach in terms of deposit and withdrawal methods. Find the one with the options you like the most and you will be all set.
  • The client support: Finally comes the client support. A good casino also has a good client support, with efficient live chat operators.

What makes a bad online casino?

There are various reasons why an online casino can be considered a bad one. As we don’t want you to have bad surprises when gambling online, we will help you identify a bad casino.

Online casino: the importance of the gaming licence

Every online casino must have a gaming licence. It is mandatory. To find out if a casino has a gaming licence, check its footer and you will find all the information you need. The gaming licence guarantees the casino you are playing on is 100% safe and fair. The licence is given by an external organisation, that assures the casino can not interfere with the odds.

If you encounter a casino without a gaming licence, you just have one thing to do: never play on this casino!

Are the bonus terms and conditions easy to comply with?

Playing with a bonus is always exciting, as you have a boosted balance. Every bonus comes with its own conditions you have to respect. Breaking the bonus terms and conditions could have your balance being cancelled by the casino. Trust us, you don’t want to be in this situation. Don’t panic, most casinos have easy to understand bonuses conditions. Most of the times, the problem is not to understand the bonus T&C’s but to respect them.

Sometimes, casinos have so many betting conditions that you don’t have much room left to have fun. Some casinos even have a list of forbidden slot machines when you play with an active bonus. Lucky for you, this betting condition is becoming less and less frequent. If you like a casino but not its bonus rules, just deposit without activating a bonus.

Something you have to check in the bonus terms and conditions is how much you are allowed to withdraw after completing your wager. Most of the times there is no limit, as you completed a wager. But some casinos will limit your withdrawals to 5 or 10 times the amount of your deposit. It is extremely rare but it exists.

We will never say it enough: always take a few minutes and read the casino’s terms and conditions before you start playing. It does not take long, and it could avoid you some unpleasant surprises. This way, you will play with peace of mind, knowing you respect their rules.

How to deposit on an online casino?

Online casinos offer a multitude of deposit methods to their players. While credit card deposits are the most common, other options can be used to credit your player account.

Here is how you can deposit on an online casino:

  • Credit card (instant): Visa, Visa Pro, Mastercard
  • Bank transfer (1 – 2 banking days)
  • Cryptocurrencies (instant): Bitcoin, Ethereum, Litecoin, Tron, XRP…
  • E-wallets (instant): Cashlib, Neosurf, Neteller, Skrill, Paysafecard…

All deposits (except in cryptocurrencies) are free of transaction fees.

Can I deposit with PayPal on an online casino?

Unfortunately, there are not a lot of online casinos that accept PayPal as a deposit method. Why? Because casinos don’t want to deal with people who deposit and then open a PayPal ticket to get their money back. One of the only casino that accepts PayPal deposits is Gamdom.

Lucky for you, Gamdom is a partner of ours and you can claim a free chest (with up to $50 inside) when registering on this casino with the code “MadnessBonus”.

How to withdraw from an online casino?

Withdrawing from an online casino is extremely easy. To make this even more simple, we advise you to verify your account immediately after you register on a casino. This way, when you win you will be able to withdraw faster. Withdrawing usually takes between 2 to 5 days.

Here are the most common withdrawal methods on online casinos:

  • Credit card (3 – 4 banking days): Visa, MasterCard
  • Bank Transfer (1 – 2 banking days)
  • Cryptocurrencies (instant): Bitcoin, Ethereum, …
  • E-wallets (instant): Neteller, Skrill, …

On most online casinos, there is a maximum amount of money you can withdraw per week and month. This amount is different for each casino. It can be 1,500€, 2,000€ or even 5,000€ per week. To find out how much you can withdraw per week and month, head over to the casino’s terms and conditions. If you like to play and withdraw big amounts of money, we advice you to play on cryptocurrency casinos.

How to become a VIP player on an online casino?

Every player want to reach the VIP rank. To be part of this private club, you have to play on the casino on a regular basis. Regularity really is the key to become a VIP player. The more you deposit and the more money you wager on the casino, the more chances you have to reach this special status. Casinos keep to themselves the conditions of access to their VIP club.

Becoming a VIP player unlocks the following perks:

  • A dedicated VIP manager, to answer all your questions.
  • More bonuses every week (deposit bonus, free spins, cashback, …).
  • Withdrawals processed faster than those of regular players.
  • A higher withdrawal limit.
  • Gifts and other surprises.

It doesn’t even stop when you reach the VIP status. Most casinos have multiple VIP ranks. Keep playing and you will level up to unlock even more amazing rewards.
