Top casino reviews



We’re used to seeing BetMGM at the very top of any casino review list, and when it comes to the best casino bonuses, nothing has changed. The site had our hearts as soon as we glimpsed their $25 no deposit bonus on sign-up, and this elusive offering is backed up by even more lucrative bonuses, such as a $1,000 deposit match.

The game library at BetMGM is vast, sporting thousands of slots, table games and exclusive offerings. The mobile site is a gem, and their customer support is unparalleled.


The renowned sportsbook company has taken the dive into the world of US online casinos, and they’ve done it with style. Next on our top online casino bonuses, DraftKings comes in with the big bucks, offering a deposit match of up to $2,000. The bonus playthrough is a little higher than we like, but DraftKings makes it easy to enjoy every moment of the time spent earning that bonus, offering a wealth of fun games, as well as a load of sports-themed exclusives harking back to their roots.

Once you’re established on the site, they also have a very exclusive VIP scheme, offering a wealth of exciting rewards to loyal players.


The casino offering from the long-established Rivers Casino brand, BetRivers, has brought an absolutely fantastic online casino bonus to the table. While the deposit match of up to $500 isn’t as high as others on this list, we were sold on the startlingly low playthrough requirements. BetRivers only requires 1x playthrough to unlock your winnings. It’s almost impossible to pass up!

This established brand also brings its years of expertise to developing a truly stellar online casino experience. We loved the great array of slots, all sporting alluring RTPs. BetRivers keeps you going with a bountiful array of free spins, tournaments and events to load up on the bonuses.

Review criteria

Even the most lucrative bonuses are ultimately disappointing if the casino offering it isn’t up to scratch. All our top casino bonuses have been chosen not just for the bonus, but also after a careful analysis of everything else the casino has to offer. Our experts used the below criteria to assess what every casino we looked at did well, and not so well. Our top casinos were the star of the show in every category.

Bonuses and promotions

It wouldn’t be a pick of the best online casino bonuses if we didn’t look at what bonuses and promotions the casinos have up for grabs, but we didn’t stop at quantity alone. To choose our top casinos, we went over the terms and conditions with a fine-tooth comb and made sure to eliminate those casinos with excessively high playthrough requirements and time limits that jump up on you a bit too quick.

When quantity did come into play — because who doesn’t want a casino site loaded with bonuses — we assessed the variety of bonuses on offer. A simple daily log-in bonus doesn’t suffice. We hunted down the very best casinos that offer free spins, loyalty programs, birthday bonuses and exclusive promo codes. In short, we looked for the casinos that had a bonus that any player, no matter their skill level, could enjoy.

Game variety

When it comes to the best bonuses, we wanted casinos that have a rich and diverse library of games so that when our bettors are getting ready to play, they don’t find themselves stuck at the starting post, struggling to find a game that suits their tastes. Our reviewers favored sites with a bottomless slot library featuring games from all the best developers, whether those are the big-hitter jackpots, video slots or classic retro offerings.

We hunted for casinos that have a wealth of table games on offer as well. Blackjack, poker, baccarat and roulette are the bare minimum, and any good casino packs in an array of less common games such as keno and scratch cards. For bonus points, we liked to see some busy live dealer tables so our players can enjoy a truly immersive experience.

Mobile apps

What’s the fun in a big bonus if you can only enjoy it from home? Mobile support is not just a bonus for us – it’s a must. Our top casinos have sleek and streamlined mobile apps, and if not, then a well-optimized mobile browser is essential. All this means you can enjoy your favorite casino games on the go.

Payment methods

We rated all our casinos on the range of payment methods available both to make deposits and withdrawals. Basic credit and debit cards are the bare bones. We also like to see more modern payment methods such as PayPal, Skrill and Apple Pay.

Customer support

When something goes wrong, it’s crucial that any top casino has a quick and responsive customer service team. Ideally, we like to see a range of contact methods, including a live chat. We gave extra points to those sites that included a handy set of FAQs for when a helpful representative isn’t on hand.

What is an online casino bonus?

When it comes to making the most of casino bonuses, it’s key to understand all the basic types, as well as what all those terms listed in the bonus terms and conditions mean.

Types of bonuses

Welcome bonus: The welcome bonus is the bread and butter of casino bonuses. Usually this will take the form of a deposit match on sign up, but rarely, you might find a no-deposit bonus that gives you cash to start just for signing up.

Reload bonus: Casinos also like to reward the players who stick around. Reload bonuses are a reward for the subsequent deposits you make after signing up, usually featuring a percentage match.

Loyalty program: For those veterans of the sites, the loyalty programs reward consistent gameplay with an assortment of exciting rewards and perks.

Free spins: Free spins are the slot enthusiasts favorite. They let you spin the reels without spending a dime.

Bonus requirements

Minimum deposit: Make sure you hit the minimum deposit requirements to activate the bonus, otherwise you might find yourself missing out.

Time limits: Usually, casinos put a time limit on bonuses, so players need to use the funds within a certain time. 30 days is typical but watch out for the shorter limits that can sneak up on you.

Game limits: Some bonuses are restricted to certain games, so keep a careful eye on this or you might find yourself with a big bonus that you can only play on games that don’t fit your playstyle.

Playthrough requirements: This is the key feature of bonus terms and conditions. All bonuses require players to wager a given amount before cashing out bonus winnings. A wagering requirement of 30x or more is not uncommon.
