Why Claim Casino Welcome Bonuses?

We can’t recommend casino welcome bonuses highly enough to our readers, because they offer so many benefits for players. Here’s a look at just a few of the reasons why you’ll want to take one of our best online casino sign-up bonus offers.

More Value for New Players

No matter what kind of online casino welcome bonus you take, they all have one thing in common: they give you additional funds or other ways to get extra play at no cost. That’s something that every player can benefit from.

Get a Taste of Different Casinos

A casino welcome bonus can allow you to try new casinos accepting US players for an extended period of time with only a small deposit – or sometimes, without any risk at all.

Build Your Bankroll

With many matching casino bonuses providing 100%, 200%, or even more in additional funds, these promotions are a great way to take a small bankroll and turn it into something that lets you enjoy casino games for a long time to come.

Try a Variety of Casino Games

Have you ever wanted to try a different slot machine, or visit another part of the casino entirely? You can try a variety of slots with a welcome bonus, and many offers also allow you to play table games or other casino classics.

Which Casino Welcome Bonus Should I Choose?

Casinos offer a wide range of different welcome bonuses, each of which is tailored to a different type of player. Here’s a look at why you might want to take one or more of these bonus types, as well as why some of them might not be right for you.

Deposit bonuses – to boost your bankroll

These bonuses offer a reward based on making a deposit into your account and are best for players ready to commit to playing at real money online casinos. Many real money casinos offer generous rewards for both new and loyal players.

Free spins – for slot lovers

Free spins bonuses provide you with free play on a slot machine in the casino. These slots welcome bonus offers are great if you want to get more play on your favorite machines or try a new slot for free.

No deposit bonuses – to try before you buy

No deposit bonuses are offers that give you money or spins to use in the casino without requiring any money on your part. This is perfect if you don’t feel comfortable making a deposit or want to try a casino without any risk.

Match bonuses – to multiply your first deposit

Match bonuses provide you with extra funds to use in the casino based on the amount you’ve deposited into your account. These bonuses will give you the greatest possible funds to use in the casino, so they’re perfect if you want maximum play from your first deposit.

Cashback offers – to reduce financial risk

Cashback casino offers provide you with a percentage of your losses back after you play in the casino. If you want to limit your downside risk and get a bit more play out of your session while staying within your budget, this is a great choice.

Top 3 Welcome Bonus Slots

A slots welcome bonus is one of the most common types of promotions given to new players, and some machines pop up time and time again when players get free spins.

Here are three of the most popular slot machines you might get to play on casino welcome offers.

• Elvis Frog in Vegas – a BGaming favorite with an old-school rock ‘n’ roll vibe. This Vegas-themed slot features coin respins, blazing free spins, and a chance to hit one of three jackpots. Catchy and fun, it’s a real crowd-pleaser. 
• Big Game Spin 16 – this unique and interactive version of the original Big Game employs the ‘Spin 16’ mechanic, where the player picks reel directions to trigger bonuses and multipliers. It’s an exciting slot for players who have always craved an interactive, choice-driven experience from their slots. 
• Major Moolah – a progressive jackpot from Rival with one payline and no bonus games. While it may be simple, it will appeal to players looking for a chance at a big payday. It has an RTP of 94.2%, making it a fair option for risk-takers. Land three Major Moolah symbols on the payline to trigger the jackpot and you could walk away with a life-changing win in a single spin. 

What to Consider When Choosing Welcome Bonus Casinos

We put many hours in research into choosing the best online casino welcome bonuses for you to pick from, but it’s still up to you to choose the one that’s best for your specific needs. The following are a few key questions that you’ll want to consider when making that choice.

• What are the wagering requirements? Be sure to read the terms and conditions that come with any bonus offer you choose. If you’re not after a high roller bonus, look for terms that pair lower wagering requirements with longer playthrough times for the best value.
• Which games can I play with the welcome bonus? This is another important part of the bonus terms and conditions, as not all bonus offers allow you to play all games. While slots are nearly universally authorized, those who enjoy blackjack, video poker, or other games will want to search for bonuses that allow such games to be played.
• Do time and cashout limits apply? Most bonuses are only available for a limited time, which will be spelled out in the bonus rules. In addition, many welcome bonuses come with cashout limits that restrict how much you can potentially win during your bonus period.

Claiming Casino Welcome Bonuses on Your Mobile

It’s just as easy to claim your casino welcome bonus on a mobile device as it is on a computer. Depending on which casino you choose, you may connect via a dedicated app that you’ll download to your device, or you’ll be able to connect to a mobile-optimized site in your web browser. Either way, you’ll get the same bonuses and range of games as any other player.

How to Maximize Your Casino Welcome Bonus

Just getting a welcome casino bonus means you’ll be getting added value out of your casino play, but we want you to get the most out of every promotion. Here are a few tips on how to make the most of a sign up bonus at an online casino.

• Find a bonus that’s right for you – make sure you take bonuses that meet your needs. If you just want to play online slots, look to maximize your free spins; if you can afford to make a deposit, find the largest matching bonus available.
• Play games that offer the best returns – every game in the casino has a different RTP (return to player) that shows how well you can expect to do while playing it in the long run. If you have the choice, play games with the highest RTP possible to increase your odds of winning.
• Read the terms and conditions – be sure to understand the rules of each bonus offer you consider. Look for promotions that allow you to play the games you want, have low (or no) wagering requirements, and allow you to cash out as much in potential winnings as possible.
