You can choose from four different welcome bonuses, with the standout being the 100% up to $1,000 casino welcome offer – although a 100% up to $1,000 poker welcome offer will suit those who are here for the poker section.

There’s also a 50% sports welcome bonus up to $1,000.

You can then claim reload bonuses each time you make a deposit, as well as participate in sportsbook contests to earn a slice of the massive prize pools that are up for grabs.

2. Ignition – Best Real Money Gambling Site for Poker


  • 100% up to $1,000 welcome bonus
  • High-traffic poker site
  • 200+ games
  • State-of-the-art software


  • Not the best for slot games

Ignition is one of the world’s highest-ranked casino sites in terms of poker traffic. There are daily poker tournaments, sharks aren’t welcome – and it eases its way into second place in our list.

Casino Games & Betting: 4/5

Ignition isn’t the most well-rounded when it comes to casino game variety. In fact, there are only just over 200 total games here, which means that anyone who’s looking for a bumper selection of slots will need to look elsewhere.

However, the biggest attraction here is poker. You can play the likes of Texas Hold’em and Omaha all day long against thousands of other players. And because traffic is so high 24/7, it’s easily the best place to turn up, choose a game, – and start competing.

Bonuses and Promos: 5/5

New players who join Ignition are entitled to a 100% up to $1,000 welcome bonus. Wagering requirements are set at 25x, which is totally reasonable compared to most other welcome offers, but you can claim a 150% up to $1,500 package if you deposit via cryptocurrencies.

There’s also an excellent VIP program that gives you the chance to earn “Ignition Miles” each time you place a bet.

Payment Methods: 4.5/5

There are 8 ways to make a deposit and process a withdrawal at Ignition. These include popular methods like VISA and MasterCard, as well as four cryptos (Bitcoin, Bitcoin Cash, Litecoin, and Ethereum).

Withdrawal times are excellent and for fiat currencies generally take no longer than 8 hours.

Reputation: 5/5

Ignition was launched in 2016. It shares its network with a number of other reputable online casino and uses state-of-the-art software.

Over the last couple of years, it’s cemented its position as one of the go-to online casinos for poker and consistently ranks in the top 5 for poker traffic.

3. Red Dog Casino – Best Online Gambling Website for Slots


  • 235% welcome bonus
  • 200+ slot games
  • Launched in 2020
  • Stylish web design


  • No online poker
  • No sportsbook

Red Dog Casino is a new online casino that’s got over 200 high-quality slot games, where the stakes can be as low as you want – and the wins as high as the sky.

Online Games & Betting: 4.7/5

The main focus at Red Dog Casino is slots, and they make up more than 75% of the total game selection. Most of them are Real Time Gaming slots, which is a major name in the iGaming world, and there are plenty of progressive jackpots here, as well as brand-new slots.

Overall game variety is a tad lacking, however, but you’ll find a decent selection of live dealer games (13), video poker games, as well as online blackjack roulette and specialty games like scratch cards and board games.

Bonuses and Promos: 5/5

New players are invited to claim a 235% matched deposit bonus that also tops you up with 55 free spins.

Then, as a regular player, you can claim daily deposit bonuses all week long whenever you make a deposit of either $30, $75 and $150.

Payment Methods: 4.4/5

Red Dog Casino only accepts a handful of payment methods but you’ll find here a few unusual options that are harder to find elsewhere like deposit by phone. Bitcoin is also accepted and a couple of other cryptos.

Reputation: 4.8/5

Red Dog Casino was launched in 2020 by Infinity Media, which is responsible for a number of other established online casinos.

Therefore, despite Red Dog’s relative newness, this is a casino site we trust. This is further justified by the fact that it’s a stylish, professional, and modern casino site that’s SSL-encrypted.

4. Bovada – Top Gambling Site for Online Sports Betting


  • 100% up to $1,000 welcome bonus
  • Over 20 sports to bet on
  • Reduced juice
  • Refer-a-friend bonus


  • Other gambling sites are better for slots

For many, Bovada is the OG of online sports betting sites, thanks to offering you 20+ sports to bet on, thousands of markets to choose from, as well as reduced juice.

Casino Games & Betting: 4.7/5

We’re gonna factor in Bovada’s sports betting markets in this section, which has helped us give it a solid 4.7 rating. Because, truth be told, Bovada’s selection of around 190 casino games is slender when compared to rival sites.

That said, Bovada is part of the same poker network as Ignition, which means online poker players will find here a solid poker site in terms of traffic.

If you love playing poker and betting on sports, this might be the site for you.

Bonuses and Promos: 5/5

The Bovada casino welcome offer at the time of writing is a 100% up to $1,000 package. Wagering requirements are fixed at 25x, which is fair.

Alternatively, you can snap up the 50% up to $250 sportsbook welcome bonus instead (but you can’t have both).

Regular players can also pocket a bonus each time they refer a friend.

Payment Methods: 4.8/5

Bovada accepts 9 different payment methods. These include AMEX, MasterCard and VISA, as well as a handful of cryptocurrencies.

Withdrawal times can take longer than average to process, with Bovada implementing a “first come, first serve” policy.

Reputation: 5/5

Bovada has been one of the most popular online casinos and sportsbooks for the last 11 years. As mentioned, it shares its poker network with a number of other top-rated casinos, while its sportsbook is practically synonymous with sports betting for many.

  • 50% up to $1,000 welcome bonus
  • Bet on over 20 sports
  • 250+ games
  • Cryptos accepted


  • Web design would benefit from improvements

If you’re looking for an alternative online sportsbook to Bovada, MyBookie comes recommended as an excellent sports betting site.

It’s especially excelling when it comes to props bets and in-play betting, it’s also got a dedicated racebook, and it posts its lines earlier than most other sports gambling sites.

Casino Games & Betting: 4.6/5

With over 250 casino games, MyBookie also outdoes Bovada when it comes to total game selection. Quality is high, too, with the action provided by big-name iGaming developers like BetSoft.

Online poker games and tournaments attract solid traffic, there’s an excellent live casino section, as well as more than 15 video poker variants.

Bonuses and Promos: 4/5

As a new player, you can choose between a 50% up to $1,000 sportsbook welcome bonus or a 150% up to $750 casino welcome offer.

Both compare favorably with rival online casinos, although the wagering requirements for the latter can be considered steep.

You can also claim referral bonuses here each time you successfully refer a friend.

Payment Methods: 4/5

MyBookie only offers a small selection of traditional payment methods. These include MasterCard, VISA, and Money Gram, but eWallets aren’t accepted.

However, you can also deposit and withdraw via 5 cryptocurrencies. At the time of writing, withdrawals are limited to $5,000 per transaction.

Reputation: 5/5

MyBookie was launched in 2014 and has wasted no time cementing its place as an attractive alternative to Bovada for sports betting fans who want someone safe and trustworthy to bet with.

It secured its license under the jurisdiction of Curacao, and we also found the friendly and prompt customer support to be a major part of its appeal.

6. BitStarz – Best Gambling Site for Crypto Users


  • 100% up to 5 Bitcoin welcome bonus
  • 3,900+ games
  • 8 cryptos accepted
  • Multi-award-winning casino


  • Doesn’t accept fiat currencies
  • No sports betting

If you’re looking for a high-quality online casino where you can safely make crypto deposits and withdrawals, BitStarz is a multi-award-winning crypto casino site that eases its way into our list as the best option for crypto gambling.

Casino Games & Betting: 5/5

BitStarz has an enormous selection of over 3,900 games. This means you’ll never be stuck for choice and it’s highly likely that most people will find something they love here. The only exception might be those looking to play online poker or bet on sports.

Other than that, you can compete in daily and weekly slot tournaments, play live games, and if you’re ever stuck on what to play next, you can hit the “Feeling Lucky?” tab.

Bonuses and Promos: 5/5

BitStarz lets you choose between three welcome bonuses – a 100% up to 5 BTC welcome package that covers your first four deposits, a 25 free spins no deposit welcome bonus or a 125% up to 1 BTC VIP welcome bonus. Anyone is free to become a VIP and claim this latter bonus upon sign-up, as well as enjoy all subsequent VIP perks.

Regular promos include a 25% cashback weekend and free spins every Wednesday.

Payment Methods: 4/5

As mentioned, BitStarz is very much a crypto-only casino, which means fiat currencies aren’t accepted here.

Crypto options include Bitcoin, Bitcoin Cash, Litecoin, Ethereum, XRP, Dogecoin, Cardano, and Tron.

All withdrawals are processed instantly and there are no transaction fees.

7. Everygame (Intertops) – Oldest Online Gambling Site


  • 25+ years’ experience
  • 300+ games
  • Over 21 sports to bet on
  • 125% up to $1,000 welcome bonus


Some people prefer signing up to established, reputable gambling sites, as the number of years an online casino has been in business is a massive seal of approval.

This is the case where Everygame (formerly Intertops) is concerned – an online casino that was launched over 25 years ago, and which continues to provide a modern betting platform that combines casino games with a sportsbook.

Casino Games & Betting: 4.4/5

Everygame is home to around 300 real money games at the time of writing, and these are split between a Classic casino section and a Casino Red.

It especially excels when it comes to online poker tournaments and table games like blackjack and roulette. There are also high-limit tables here, which will suit high rollers.

Over in the sportsbook, meanwhile, you can bet on 21 sports and choose from an excellent array of props bets and futures bets (especially for American sports).

Bonuses and Promotions: 4/5

Because Everygame is split between a Casino Red and a Casino Classic, you also get to choose between two welcome bonuses.

The Red offer is a 125% up to $1,000 welcome bonus, while the Classic offer is a 100% up to $100 welcome bonus. Both come with 30x wagering requirements.

Regular players can then take advantage of a series of regular casino and sportsbook promos, including free spins, cashback offers, and parlay boosts.

Payment Methods: 4.4/5

Everygame accepts a good mix of regular payment methods, such as MasterCard, Discover, and Money Global, and cryptocurrencies, including Bitcoin and Bitcoin Cash.

Reputation: 5/5

A casino site doesn’t survive for 25 years at the top of its game unless it’s doing everything right. This is certainly true of Everygame, a genuine fan favorite that’s stayed relevant and modern throughout its existence.

Today, it continues to provide a stellar and reliable online gambling experience to customers who are looking for somewhere safe and trustworthy to place their bets.

Online Casino Games & Betting: 4.4/5

Wild Casino’s live dealer games are split into two sections: Casino Red and Casino Black. Most of the games are provided by Fresh Deck Studios, and most of the tables allow for unlimited players at any one time.

9. Cafe Casino – Best Mobile Games of any Gambling Site


  • 250% welcome bonus
  • Excellent mobile app
  • Cryptos accepted
  • User-friendly site design
  • Great choice for slots


All our top 10 online casinos are mobile-optimized, but Cafe Casino stands head and shoulders above them all with its streamlined, user-friendly mobile version that makes playing casino games on the move a super smooth experience.

Casino Games & Betting: 4/5

The overall game selection at Cafe Casino stands at just over 160. This is a comparatively small quantity of games, but the variety is good. You can play over 120 slots, as well as a good selection of table games and specialty games, and there are 5 live dealer tables here as well.

And as mentioned, all games are optimized for mobile play, which is to say you can play at Cafe Casino in your mobile browser.

Bonuses and Promotions: 5/5

The regular Cafe Casino welcome bonus is a 250% up to $1,500 offer. Crypto players, however, can instead claim a 350% up to $2,500 welcome bonus, which has the same wagering requirements.

Then, each time you successfully refer a friend, you’ll receive an extra $100 in your account (or $125 if you use crypto).

Payment Methods: 4/5

Cafe Casino is like most of our other top gambling sites in that it accepts both fiat currencies and cryptocurrencies.

American Express and MasterCard are among the regular payment options, while cryptos include Bitcoin and Bitcoin Cash.

One slight downside is that Cafe Casino limits all players to just one withdrawal every 7 days.

Reputation: 5/5

Cafe Casino was launched by Arbol Media in 2016. It’s attracted a lot of praise over the years for its fantastic mobile app and regular promos, and it remains a safe and legit option for anyone who just enjoys having fun at a casino site.

10. Slots.LV – Best Bonuses of any Online Gambling Site


  • 4 different welcome bonuses
  • 250+ games
  • Daily jackpots
  • Weekly double-up bonus


With a weekly double-up bonus, a Slot of the Week promo, and a number of other creative offers, Slots.LV may slot into last place in our top 10 – but it’s easily our preference when it comes to bonuses.

Casino Games: 4/5

Slots.LV is most definitely a slots-focused casino site, with reels making up around two-thirds of the total games here (there are 195 online slots in total at the time of writing).

However, we still feel that there’s something for everyone, with Slots.LV is also home to 14 poker games, 8 blackjack variants, 5 live dealer games, and a range of specialty games, such as bingo.

Bonuses and Promotions: 5/5

We’ve already stated part of our case in defense of Slots.LV being crowned the best for bonuses. But once again, it’s worth pointing out that this gambling site lets you choose from four different welcome bonuses.

Essentially, you can snap up either a 200% up to $1,000 casino welcome bonus or a 200% up to $1,000 live dealer welcome bonus if you make your first deposit via fiat currency.

If you deposit via crypto, you can claim either a 300% up to $1,500 Bitcoin casino welcome bonus or a 300% up to $1,500 live casino welcome offer.

Payment Methods: 4/5

Slots.LV offers 8 different banking options – and 5 of these are cryptos.

You can deposit and withdraw via BTC, BCH, LTC, ETC, USDT, VISA, MasterCard, and AMEX.

Curiously, while Slots.LV offers customers who withdraw via VISA their first withdrawal of every month on the house, all subsequent withdrawals made that same month come with a $50 fee.

Crypto withdrawals, however, are always free.

Reputation: 5/5

Slots.LV has been around for a number of years and has amassed thousands of customer reviews, which is enough to suggest that this is a highly trustworthy casino site.

It’s also fully licensed and SSL-encrypted.
