    What is an online casino welcome bonus?

    A welcome bonus is first of all a gift or a bundle of offers, which a player usually already receives when registering at the casino free of charge, quasi as a reward for the registration. Often a so-called deposit bonus is also granted, which usually doubles the deposit amount . But you don’t need to make a deposit to get the regular online casino welcome offer.

    Types of Welcome Bonus at Online Casinos

    The beauty of this online casino bonus is the fact that there isn’t just one type of welcome offer; there are two:

    • Deposit welcome bonuses
    • No deposit bonuses

    Deposit casino bonuses require you to top up your account to claim a reward . That is the case with the first type of welcome bonus offer. For the casino to transfer it to your account, you must make the minimum required transaction. Once you do, the casino will match your deposit and provide you with extra funds . In many cases, you will also receive bonus spins. They are usable on certain slot games. Keep in mind that free spins winnings also need to be wagered.

    The second type of welcome bonus is the no deposit offer . You receive these offers without actually making the minimum deposit. The casino transfers bonus money or free spins immediately after you register an account.

    Welcome Bonus Codes

    In some cases, the casino might even include a bonus code . This code is used for one of two reasons. First, some casinos require you to enter a code when claiming the first deposit bonus. Once you enter the code, then the online casino will transfer the reward to your account. The second usage of the code is to gain access to unique rewards . Online casino sites are known for partnering with other platforms via various marketing strategies .

    As a result, they provide them with codes that they give their clients. These codes unlock unique deposit bonuses and make the gaming experience all the more exciting.

    Entering bonus codes is simple as ABCs. All you have to do is click on the “Claim Bonus” button in the promotions section. You will see a field that says “ Enter bonus code .” This is where you must type in the code. Then, finalize the process and reap the benefits.

    Claiming a Welcome Bonus

    Just like all other online casino bonuses, the welcome offer is relatively easy to claim . There are just a couple of steps that you need to complete, all of which are explained below.

    1. Find a Reputable Online Casino. The first step of the process is finding a reputable platform , one that has a good welcome bonus. Make sure that the platform is licensed and regulated by a well-known authority. Additionally, the site should utilize the latest SSL encryption software.
    2. Register an Account. Once you’ve found a casino that matches your personal preferences , it is time to register. Click on the sign-up button and fill in the required fields. Some of the information that the casino will ask of you is first and last name, email address, phone number, etc. Accept the T&Cs and finalize the process.
    3. Deposit Money and Enter Bonus Codes. Check what is the minimum deposit amount for the welcome offer. Before you transfer the funds, enter the bonus code to receive online casino signup bonus. Once the transaction is complete, you will instantly receive the deposit casino bonus.
    4. Use the Bonus on the Eligible Casino Games. After the casino transfers the reward, your bonus balance will increase and you will have the chance to use the reward on casino games. Don’t forget to read the terms and conditions to get familiar with the bonus validity period, wagering requirements, etc.

    Wagering Requirements

    Wagering requirements are the most important and most complicated part of a casino deposit bonus. The case is no different with welcome offers.

    The general rule of these promos is that the lower the contribution is, the better. Here’s why. Playthrough requirements indicate the amount that you need to stake at the casino before you can withdraw bonus winnings. Keep in mind that bonus bets here are not qualifying. You need to wager real money to meet the wagerings. Allow us to explain this T&C via an example.

    Let’s say that you’ve registered at an online casino site where the welcome offer is a 100% matched deposit bonus that goes up to £100. The minimum deposit for the bonus is £20. Bonus wagering requirements are set at x40. This means that you will have to wager a total of £800 before you can withdraw winnings made with the bonus funds count. Why £800? You multiply your deposit with the wagering requirements.

    So, if you deposit £20 and the requirements are set at x40, you multiply these two amounts and you get the final sum – £800. Keep in mind that you must meet the requirements within the bonus validity period. If you don’t, then the casino has the right to forfeit the bonus amount.

    How to Find the Best Online Casino With Welcome Bonus – Tips

    When you register at a certain casino site, it is logical that you will want access to the best casino bonus offers . After all, the operator must meet or exceed your expectations. There are a few ways through which you can find the best casino bonus sites.

    That’s exactly what we’ll focus on in this section. We’ll list a few tips that you can follow to have a good gaming experience.

    • Minimum Deposit. First things first, whenever you want to claim deposit match bonuses such as the welcome offer, you must make sure that the qualifying deposit is not too high . The lower the limit is, the better. That way, you’ll enjoy massive flexibility and you will have the chance to make a low or high cash deposit, depending on how much extra funds you want to receive.
    • Wagering Contributions. As mentioned earlier, before you can withdraw bonus wins, you must meet the wagering requirements . If they are high, then you will have to stake a lot of real money. That makes it harder for you to cashout winnings with the bonus offer. So, always search for casinos where you don’t have to wager a lot of money to withdraw the bonus spins winnings credited.
    • Market Restrictions. All casino bonuses, welcome offers included, come with certain market restrictions . These can be eligible payment methods, minimum deposit, country restrictions, casino games on which you can use deposit free spins, max bonus conversion and maximum bet.Before you make your initial deposit and claim a UK casino bonus, it is vital to read the terms and conditions to see whether any of these restrictions apply to your preferences. For instance, when you receive the welcome deposit match bonus and it features extra spins, you might not be able to use them on your favourite slots. After all, game restrictions are a common thing with the welcome bonus credit.Additionally, payment method restrictions also apply. In the UK specifically, the UKGC banned the use of credit cards in 2020 .
    • Bonus Validity Period. Finally, we have the timeframe in which you must meet all terms and conditions. There’s one general rule here – the longer the validity period is, the better. This is a major benefit, especially if the wagering requirements are high.

    Conclusion

    Whenever the topic of best casino bonuses is brought up, welcome bonus casino sites are the first thing that comes to mind . These online casinos with sign up bonuses are available to new players only and they provide you with extra funds and bonus spins. Not only that, but some operators might not even require you to make a min deposit to claim them.

    Instead, they provide you with a free bonus immediately after you register an account . One thing that you should always keep in mind is that the welcome bonus is a one-time offer and it comes with several restrictions such as casino games selection, maximum bonus amount, game contributions, etc.
