Multiple deposit options are available at Cafe Casino. Bitcoin, Ethereum, Litecoin, Bitcoin Cash, and Tether are all acceptable, as are major credit cards like Visa, Mastercard, and American Express. MatchPay, player transfers, and direct bank transfers are alternative payment methods.

With a minimum deposit of $50 (promo code CAS150) or $100 (promo code CAS250), BetUS Casino will match your initial deposit by 150%, up to $3,000 or $5,000, respectively.
Both bonuses have 14-day expiration and rollover requirements. Other bonuses are also available for casino and sportsbook bettors, catering to both crypto and fiat users.
BetUS Casino offers an impressive selection of over 450 casino games. There are three hundred and fifty slots, eighteen blackjack variants, three video poker games, and five roulette games available.

Las Atlantis entered the market in 2020, making it a relatively new casino within the online gambling space. Despite this time frame, the site quickly developed an excellent reputation. You’re treated to a modern design, mobile-friendly features, and access to the latest casino games.
The most impressive point is the current Las Atlantis welcome bonus. Register for a new account and claim up to $14,000 in bonus credit across your first five deposits. Each deposit is matched by 280%, meaning you only need to deposit $1,000 each time to claim the full casino bonus amount.
On top of this, you can claim a no-deposit casino bonus of up to $40 by messaging the support team. We recommend claiming this before depositing to try out the site and potentially win some bonus money along the way. If you like what you find, deposit $1,000 and claim the maximum amount. Keep on reading our full Las Atlantis review.
A welcome bonus is a term that describes promotions exclusively for new players. They’re also referred to as new player offers or sign-up bonuses. To become eligible, you need to register for a new casino account and usually make an initial deposit.
All US online casinos offer a welcome bonus as an incentive to join. In the highly competitive landscape, the best online casinos now offer a bonus amount on several deposits as part of a welcome package. These are typically the most lucrative and give players a significant advantage over the house edge.
Most welcome offers require only registering for an account and making a minimum deposit. Here is a step-by-step guide on how to do this at Las Atlantis, our experts’ top pick:
Click any of the links on this page to navigate to the Las Atlantis website. Hit the pink “Sign up” button in the top right corner and complete the short registration form. Click “Register” to finalize your account, then check your email for an account verification link.
You can make your first deposit via the cashier screen. Select “Bonuses” from the top menu and click on the “280% Slots Bonus” promotion. Clicking the “Redeem Coupon” button opts you in for the offer. You can then choose your preferred casino payment method and fund your account by following the on-screen instructions.
Within a few minutes, your account balance will show your deposit and newly awarded bonus credits. Head to the Las Atlantis slot games lobby and browse their extensive selection of titles. Place real-money bets using your bonus and earn real-money payout.
Playthrough requirements (also called wagering requirements or rollover) apply to every casino promotion. They can be frustrating as they stand in the way of withdrawing your winnings right away. However, they protect the online casino, as without them, casino operators wouldn’t be able to offer such lavish rewards.
They’re relatively easy to understand, as follows:
It’s important to remember that you don’t need to lose this much money; you need to wager this much. Nevertheless, lower rollovers are preferable, making it easier to complete the requirement and withdraw winnings.
Most offshore online casinos offer signup bonuses as a promotional tactic to entice new players to register for an account. Operators typically hand out bonuses once you make your initial deposit, ensuring that you’re committed to spending at the site before they give out free money.
As the online gambling industry is becoming more competitive, casinos must offer bigger and better promotions to compete in the market, and that benefits players like you.
All players new to the online casino can claim sign-up bonuses. You need to register for an account and usually must make an initial deposit to qualify.
These promotions aren’t available if you already hold an account with the online casino. Don’t try creating a new account with a separate email and login, as this violates the terms of service. The operator will detect accounts that are running on the same IP address and instantly close your account, seizing any funds in it.
The good news is that all top online casinos run signup bonuses to entice new players. And with thousands of online gambling sites, an attractive promotion will always be available.
All welcome offers are unique, and the casino decides the games you can play. They’re always detailed in the deposit bonus terms, and it is vital that you check any restrictions. Playing excluded games will waste time and money in claiming the deposit bonus.
All the best casino bonuses can be used on slots, with some exceptions like hot-drop jackpot games and network progressives. Electronic table games are sometimes allowed. Live dealer games are often excluded while gambling online with bonus credits and clearing the rollover.
The best welcome bonuses have low wagering requirements that are easy to clear. This makes it easier to get your winnings and capitalize on the offer. Also, check the time limit to complete it. The longer the timeframe, the easier the task.
Check if the online casino bonuses are valid on slots only or additional games. You can only play eligible games for the bonus, so make sure you’re happy with the available selection.
Most casinos cap the winnings you can get from a bonus, preventing you from taking home millions on free spins. Look for promotions with the highest maximum winnings. Casinos may offer a fixed cap (such as $10,000) or a multiplier of your deposit amount (such as x30).
Bets can also be limited. If you’re a high-roller regularly placing high-risk, high-reward wagers, you’ll want a high ceiling, so your gameplay isn’t restricted. All players should be cautious, as going over the max bet may void the online casino bonus.
Always check if you need to enter casino bonus codes to opt in for a welcome promotion. You can miss out if you fail to enter the code when first funding your account.
Deposits made with some banking methods may not be eligible for the bonus. Some online casinos also offer additional perks for using a preferred payment method for deposits, so check this to claim the maximum reward.
Most welcome offers require promo codes. This must be entered on the payment screen when making your first deposit.
As always, there are some exceptions. Some promotions apply automatically when you make a qualifying first deposit, but you may have to choose the offer from the rewards tab on the site. Exclusive offers – such as the uncapped 275% Red Dog Casino bonus – are only available by messaging customer support.
All players can win huge amounts of real money with a casino sign-up bonus. However, you cannot withdraw the bonus money immediately as cash. You must use it to play your favorite real money casino games, and winnings become available for withdrawal as soon as you clear the playthrough requirements.
The best online casinos are mobile-friendly and built using HTML5 technology. Mobile betting is undoubtedly the way to gamble online. You can take the thrills of online casinos wherever you go and win real money while on your morning commute or queuing for groceries.
You can also claim welcome offers from your smartphone by registering and depositing funds from your iOS or Android device. You don’t need to download any casino apps for real money. Go to the casino site using your smartphone browser and complete the standard signup process. The sites function the same as their desktop counterparts.
Deposit match bonuses are the most common promotions. The casino matches your initial deposit (or first few deposits) by a percentage. The more you deposit, the more bonus credit you receive. The best match deposit bonuses have high percentage matches and high caps.
High-roller bonuses are new player promotions tailored explicitly to big spenders that place bigger bets. They have higher maximums and generally allow you to place bigger bets while clearing the online casino bonus. Red Dog’s uncapped 280% welcome bonus on the first deposit is a great example.
Although rare, online casinos sometimes award new players small amounts of bonus credit or free spins without requiring a deposit. These are known as no-deposit bonuses. They primarily let you try the games before funding your account, and winnings are real money.
No, you cannot claim the same welcome bonus more than once. Welcome offers can only be claimed by new players registering for the first time, which you can only do once per site.
Yes, you can claim a welcome bonus on a mobile device. You need to create an account and make your initial deposit from your smartphone.
