The online casino welcome bonus is everybody’s favorite. It brings plenty of bonus money or free spins right into your hands from the beginning. It will multiply your original deposit with a great multiplier and allow you to play many more games, especially if you want to play online slots. What you should check is the match percentage (how many percentages the provide will match your initial deposit), the total amount that you can get (maximum limit), and the wagering requirements (playthrough). The combination of these 3 factors creates the best promos.

Are the best welcome bonuses, the best deals that iGaming apps and sites can offer?

That depends on you completely. If you are looking to try a new casino site, this type will be the best one. But if you are looking for an app or portal for the long run, you should check the reload bonus promos and loyalty program. They might be more important if you stick to a single provider.

An online casino with welcome bonus can have a great reload deal, too. So, you can get everything from the same place.

So, let’s not waste any more time and see which is the best deposit bonus for you. Which real money online casinos to choose from? Which one will bring the right incentives that will make you excited and give you a chance to win?

What is an online casino signup bonus?

The welcome deal is an offer that many gambling sites use as an incentive to attract new players by giving rewards in the form of additional bonus money matching the player’s first deposit, free spins, free credits, free sports bets, and more. The more added perks there are, the better for you as a player. You will have more ways to have fun, and you can extend your time on the site or app.

The initial casino bonus offer is one of the best-known promotions in the industry. It is the massive number most of the portals show you first. As you can see, we are also guilty of this. Sometimes the welcome deal is combined with a no deposit promo, and it is advertised as an online casino signup bonus. It could have different names, but now you know what the essence of it is.

You can see it as a core promotion of every gambling website or app. The juicy reward that gives many additional chances for rewards. The deal is essential for the player’s experience and helps him or her to try casino games, using this bonus cash instead of their money.

The typical sign up bonus has the following characteristics:

  • Matching percentage
  • The maximum bonus
  • Wagering requirements
  • Game contributions
  • Expiry period
  • Minimum deposit

Matching percentage

The apps and portals usually have a match bonus policy that matches the deposit, according to the multiplier. If a welcome promotion has a 200% match, you will get twice the amount you deposited, up to the amount the gambling site allows.

The maximum limit

In the terms and conditions, you will see the “Up to..” sign. It will indicate which is the maximum match the portal will give you for the deposit bonuses. If you deposit more than the casino offers to match, you won’t get additional money for the deposit above the value.

Wagering requirements

The wagering requirements show you how much you should play until you can withdraw the money from your deposit. It is often shortened as WR. The WR usually is between 15x and 30x for US-based casinos. An important thing to note is if the requirements are based on the deposit only or the deposit + the welcome bonus. In the second case, the playthrough will be much higher, and it will be much more difficult to claim the bonus.

Games limitation

The online casino welcome bonus can often be used for all real money games that the site or app offers, but in some cases, there are exceptions. If you get free credits for online slots, you can use them on the exact game the promo indicates and no other. Some iGaming portals don’t let you use these casino bonuses on games of skills like poker or blackjack.

Expiry period

From the moment you claim a bonus, the time starts ticking. You can have 1 week, 2 weeks, or another period, but it is almost certain that your welcome deal will expire in a short time.

You should know what a welcome bonus code is too. Many apps and sites offer promo codes. There are special combinations of characters that unlock perks when you enter them on the gambling’s site or app.

Learn what the difference between a no deposit and a deposit bonus is. Both can be sign up bonuses, but the first does not require you to add funds, while the second will require a minimum initial deposit.

Both are welcome offers, but the biggest welcome bonuses require you to add cash to your account. For both, you will most probably need a promo code, which you can redeem during your registration or later through the Cashier, depending on the gambling site.

Most online casinos will offer both, sometimes at the same time, and you can use them to play real money games.

And lastly, are welcome bonus offers common in the US? Yes, almost every US app and site offers one type of such promotion to attract new customers.

Online casino sign up bonus and its types

What types of online casino welcome bonus are there? There are multiple types such as: additional money, free credits, promo sports bets, or free play on the slot machines. Let’s explore them one by one.

Additional money

Some of the best ones involve a big sum of extra money. You can find such a perk as a deposit welcome bonus. There more you get, the better. Yes, you need to check the T&C, but in general, you want a high amount and a low, or at least reachable, WR. Many times, the WR is calculated not only based on the extra cash but on the sum of the deposit and that money. That makes it harder to claim. For this deal, you will most probably need a promo code.

Free bets

If you are playing on a gambling site or app that is also a sportsbook, you can get free sports bets too. If you are a sports fan, the best welcome bonus online casino includes multiple free bets for the sport you prefer.

Free spins

Slot machines are the most played real money game, both online and offline. Many gambling sites offer such a deal that includes credits for all of their slots. In some cases, the apps or sites offer free play for their new games, too. You can get some spins and try out the new online casino games without betting real money.

No deposit

As a part of the promotion that comes with your first deposit, you can get additional no deposit perks, too. It is usually small, around $40-$50, that you can get even without depositing a single dollar. These casino welcome bonuses are not common, so if you see them, grab them! Take full advantage of them!

How do casinos benefit from the sing up bonuses?

These online casino welcome bonuses attract new players to the gambling portals. They are like advertisements that aim to bring people to them. And they have to do it. The competition in the industry is outrages. Yes, there are many potential clients, but usually, if people like one platform, they stick to it. After that, the apps and sites aim to keep you on their sites with great online casino games and additional promotions. Remember, the smartest thing that you can do is to shop for offers. Nothing stops you from claiming multiple online casino welcome bonuses from various sites.

Pros and cons of online casino signup bonus

Pros
  • Free money – Originally, you were thinking about playing only with the money you deposited. Now you have extra money that you got thanks to the sign up bonus. Enjoy them the way you like!
  • Extend your game session – If you have $1000 and you thought you would play 100 games, with an additional $1000, you will have $2000 to bet and many more chances to win. You can double your game time or bet higher wagers at the same time.
  • Cash out when you complete the terms and conditions – After you accomplish the wagering requirements, the amount you have at that time is yours. You can withdraw it from your account using the payment method you prefer. In some cases, there are maximum winnings that an app or site has.
Cons
  • There are limits – A typical online casino with a Welcome bonus will have a match percentage and maximum amount. You can’t deposit a million dollars and get 1 additional as a bonus. The iGaming platforms set these limits, so they can balance their promotional expenses. An amount of around $1000 for US portals is good.
  • Wagering requirements – Make sure you choose a casino with a realistic WR. If you see 50x WR (deposit + bonus), it will be really hard to claim that promo. Better choose platforms with WR around 35x, and if it is related to the deposit only, that will be a lot better.

Online casino signup bonus FAQ

Why do online casinos offer welcome bonuses?

They do it to attract new users. It is a part of their promotional budget, and it is one of the biggest marketing expenses they have. They are willing to spend the money because the competition is strong, and they need to get players’ attention.

Why the best first deposit bonus is not always the biggest welcome bonus?

Because the promotions have multiple characteristics. Sometimes a big deal of up to $10 000 can have a very unrealistic 55x WR. Such a promo can be really hard to claim. On the other hand, there could be a small bonus of up to $200 with WR x10 which could be a lot better for you.

Can I withdraw the first deposit bonus?

Yes, you can withdraw your winning just after you finish the WR. You need to play through your promo amount before you can claim it.

The WR indicates the playthrough amount that you need to pass in order to claim your additional cash.

What are the best games to play at an online casino with free signup bonus?

Slots are almost always the games with 100% game contribution, but if you have special skills for another game, like blackjack or poker, you could have better chances with them.

Of course, you can win real money with such a deal. You need to play through your additional cash, and the final amount you get, if there are no winning limits, can go directly to your bank account.

Yes! You can register at all the gambling apps and sites that allow players from your country and region. You can claim promotions from them and play. Remember, you can claim an online casino signup bonus only once per site.

Can you play all online casino games with money from my promo deal?

No. Many times a deposit welcome bonus will have many restrictions, including game restrictions. It is often that games of skills are excluded from this promotion.
