CASINO WELCOME BONUS

Some players might not know that bonuses may come rolling in the moment they sign up. One of the most popular online casino bonus offers, and the first Deposit Bonus new online casino players often claim, is the Welcome Bonus. Although the availability of the Welcome Bonus depends on the player’s jurisdiction, generally, the casino will deposit an additional amount of money after the player registers a new account and makes their first deposit.

In many cases, the Welcome Bonus would match or offer a percentage of the first deposit, typically in bonus funds (separate to cash funds), up to a certain amount. EnergyCasino’s Welcome Bonus, for instance, is a 100% bonus up to €200 upon placing the first deposit. It’s our way of welcoming new players to the Energy adventure to help kick it all off with a spectacular bang! Apart from bonus funds, new players may be awarded free spins or cash funds as part of the Welcome Bonus package, depending on the player’s jurisdiction.

TERMS AND CONDITIONS

Since every player loves a good Welcome Bonus, these brilliant deals are often used as a way to attract players to the casino. With a bit of scouting, you may find one particularly appealing. If this is your first rodeo, one of the most important things to consider before claiming the Welcome Bonus is its Terms and Conditions.

The promotion’s Terms and Conditions will help you learn the ins and outs of the Welcome Bonus. They would list everything you need to know and all the requirements you would need to fulfil before claiming. Rewards like bonus funds, cash funds and bonus spins are often subject to wagering requirements, which must be completed before the bonus expires. Bonus funds cannot be withdrawn from a player’s account until all requirements have been met.

Deposit Bonuses may specify a minimum deposit to receive the rewards at all. Jurisdictional limitations, qualifying slot games, max. bonus win and a minimum bet or max. bet cap may also be among the criteria that may keep you from being eligible to claim the offer.

We highly recommend giving the Terms and Conditions a solid run through before hitting the ‘CLAIM’ button and updating your deposit balance. There’s no worse feeling than claiming a bonus you think you’d enjoy only to find out that you do not or can’t meet the requirements.

Suppose you happen to come across a deal that you’re not eligible for. In that case, you can try to earn bonus funds through casino tournaments, promotional events or by simply waiting until another bonus rolls in — that’s the beauty about playing at online casino sites!

Everything You Need to Know About 100% Casino Bonuses

Your 100% no deposit bonus may become a heavy weapon in your hands that will allow you to extract some real cash, test new games, and accomplish who knows how many more other goals, but only if you learn how to maximize this bonus to the fullest. We’ll decipher it in the paragraphs below, and now let’s name the most important aspects:

  • Bonus type: welcome, match, no-wagering; cashable, non-cashable.
  • Wagering requirements: apply (usually) or not apply.
  • Limit to the amount of withdrawable bonus money: applies (usually) or not applies.

What Exactly Is 100% Bonus?

A casino 100% bonus is a reward granted to you by the casino as a part of another bonus or as a standalone bonus. 100% bonus means that the real cash bonus amount will equal your deposit amount. For example, if you’ve deposited $100, your 100% bonus will be $100, granting you a total of $200 to play with; if you’ve deposited $500, your 100% casino bonus will be yet another $500, granting you a total of $1,000 to play with. And so on.

As you can see, ‘100%’ has to do with the bonus size but not its type. A 100% bonus may be of the following types:

  • Welcome bonus. The most widespread is a 100% welcome bonus, which will double up your initial deposit to give you a great boost at the very beginning of your gaming career. It’s worth noting that this welcome bonus usually has a lower playthrough requirement than its bigger peers of 200% and 300%.
  • Match (deposit) bonus. A 100% match bonus is another super-popular casino perk granted to regular depositors. As a rule, this type of bonus has an impressive upper limit of up to a few thousand dollars.
  • No-wagering bonus. It’s an absolutely best-case scenario. A no-wagering 100% bonus is a gem, as you don’t have to complete the playthrough requirement. In other words, all bonus money is yours from the very start and with no strings attached. A no-wagering 100% bonus is always small in size, up to a few dozen dollars, but hey, it’s still free, and you can do with it whatever you want!

Why Do Online Casinos Offer 100% Bonuses?

You might think it’s unreasonable for casinos to offer generous perks to players, but, of course, it’s all well-calculated. Most casinos have large budgets of millions of dollars, and they all play long-run. It doesn’t matter to them if you’ve won a few hundred dollars from them. As long as you are well on your way to becoming a regular, that would bring all that money back and then some.

  • Attract new players. 100% welcome bonuses suggest an excellent motto: Get Your Money Doubled! It works like a magnet for new players, as they can only deposit half of the money they will have to play with. One example of such use of the 100% welcome bonus is the Conquer online casino.
  • Make you deposit more over time. It goes without saying that once you’ve tried the real-money play, you get excited, and with a casino 100% bonus at hand, you often get overexcited, which leads to excessive losses and more deposits.
  • Make you a casino follower. It’s quite hard to get off the hook once you’ve felt all the advantages of real-money play. Free credits do not excite you anymore – you’re craving real battles with real money at stake. At this stage, you become a casino follower.
  • Make you an affiliate. Surprisingly enough, you don’t even have to spend YOUR money to help the casino promote itself. In a while after receiving your bonus, you might want to invite your friends for the same bonus, and that’s how your referral career may start. More invites will generate more money, and the win-win deal will benefit you, the casino, and maybe even the attracted players, who may also get some perks from your referral link.

Any conscious gambler can quickly nullify the disadvantages of any bonuses while reaping the benefits to the fullest.

How to Claim Your Real Money 100% Casino Bonuses?

Claiming your 100% bonus is no harder than claiming any other casino bonus, but there are a few nuances to take into account, especially if you’ve never claimed bonuses before:

  1. Register with the best casino you can find. The importance of selecting a credible online casino cannot be overestimated. Up to date, there are still casinos that don’t fulfill their obligations, so you must be very careful with it. To safeguard yourself against all sorts of trouble, we recommend you use our ready-made list of verified online casinos with 100% bonuses.
  2. Read the bonus terms & conditions. Every casino has a bonus term & conditions page on which it elaborates on all the conditions and limitations that must be met before you can withdraw your bonus and (or) bonus winnings. These limitations may or may not include geographical restrictions, wagering requirements, players/games/deposit methods excluded from the bonus offer, and other conditions, so we strongly recommend you peruse the bonus T&C page of your casino before taking action.
  3. Choose the bonus with the best wagering requirements. That being said, the accompanying conditions – the wagering requirements – define whether it is expedient to deal with the bonus offer. Therefore, make sure the playthrough requirement is not too high (30x and better will do), and the upper limit to the maximum amount of bonus winnings isn’t too low (a few hundred dollars will do).
  4. Claim your real money bonus and complete the wagering. Some bonuses might be claimable via email, live chat, or promo codes, but 100% bonuses are often credited automatically once you’ve made your deposit. Nevertheless, make sure you are aware of how to claim the bonus.
  5. Withdraw your money or play with it. Once you’ve played through your real cash bonus, you are free to do with your money whatever you want – you can instantly withdraw it or try to win even more.

What Are Wagering Requirements?

As you already know, not only the size of the bonus matters but also the wagering requirements – the conditions that you have to fulfill to withdraw your bonus and (or) your bonus winnings. Depending on the casino and the type of bonus, the wagering requirements may include:

  • Playthrough requirement. A playthrough requirement is a number that defines the total amount of money that you must wager on casino games to convert your bonus money into cash. For example, a 30x playthrough requirement means you must wager at least 30 times more than your bonus amount. Naturally, the lower the playthrough requirement, the better. The best-case scenario is the no-wagering 100% bonus, as it requires no wagering.
  • Eligible games and contributing percentages. Unfortunately, not all games count the same towards the playthrough requirement, and not all games count. You can find this info on your casino’s bonus T&C page. For example, if slots and table games contribute 100%, every dollar wagered on slots and table games count as a dollar towards the playthrough requirement. Still, if craps and video poker counts 20%, every dollar will count as 20 cents towards the playthrough requirement. As simple as that.
  • Maximum withdrawable amount. Sometimes players catch their lucky breaks, and casinos want to be safe when that happens, so most online platforms will establish a cap on the number of bonus winnings that you can cash out. As a rule, the cap is a few hundred dollars or a few thousand at best.
  • General restrictions. Last but not least, some countries, states, territories, and some banking methods may be excluded from the bonus offer, so you should check that out in advance.

100% Bonus Casino FAQ

A 100% casino bonus is any bonus that gives you an extra 100% of your real-money deposit. This bonus can be of different types, including but not limited to welcome bonus, match bonus, and no-wagering bonus.

Once you’ve got your bonus money, you have to convert it into cash by completing the wagering requirements established by your casino.

Are There Any Wagering Requirements for 100% Bonuses?

Yes, wagering requirements apply to all 100% bonuses except for no-wagering, which is rare. Typically, wagering requirements define the total amount of money you must wager on eligible casino games before cashing out your bonus (if cashable) and your bonus winnings. Wagering requirements may or may not apply to both the bonus and the bonus winnings.

Who Can Qualify for 100% Bonuses?

The qualification requirements are established by your casino, but basically, it’s enough to make the minimum deposit to the casino eligible for a 100% bonus. However, as being said, additional qualification criteria may apply in some cases.

  5. Complete the wagering requirements and do with the money you’ve won whatever you want.

For example, you can first take advantage of a 100% welcome bonus, then grab a 100% match bonus, and then avail of a 100% high-roller bonus. There’s absolutely no limit to the flexibility of 100% bonuses!
