The best online casinos should have high payouts and bonuses (Source).

The 8 most popular online casinos are DraftKings, Hard Rock Bet, Golden Nugget, PlayStar Casino, BetMGM, Bovada, JackpotCity Casino, and Bet365. They offer a diverse game portfolio, high payouts, and impressive bonuses.

DraftKings

DraftKings, one of the best mobile casinos, is widely recognized for its user-friendly interface and extensive game library. It operates legally in multiple U.S. states, including Pennsylvania, Connecticut, Michigan, West Virginia, and New Jersey.

Below is DraftKings comprehensive selection of gaming options:

Sportsbook: DraftKings covers a wide range of sports, such as football, basketball, and baseball, with various betting options (e.g., prop bets, future bets, and live betting).
Daily fantasy sports (DFS): Players create fantasy teams to join contests across multiple sports, such as Showdown Captain Mode and Snake Drafts.
Casino games: You have the option to try slots, table games, live dealer options, and more. Notable games with high RTP percentages include Mega Joker (99%), Blood Suckers (98%), and Medusa Megaways (97.63% and up to 50,000x max win.

Payouts at DraftKings vary based on the type of bet placed. For example, a straightforward moneyline bet’s payout depends on the odds — wagering $100 on an underdog at +200 odds yields a $300 return ($200 winnings plus the original stage). Meanwhile, a parlay combining three bets with +300, +250, and +200 odds pays out 20 times the original stake if all legs win.

Regarding bonuses, DraftKings offers a range of promotions for both new and existing users, including Welcome bonuses (100% deposit), deposit reloads, profit boosts, free pools, and monthly contests.

The most notable bonus is the Dynasty Rewards program. Participants place bets or play casino games to earn “Crowns,” which can be redeemed for various benefits, such as site credits for future bets, entries into contests, or exclusive merchandise through the Dynasty Rewards store.

Hard Rock Bet

Formerly known as Hard Rock Sportsbook, Hard Rock Bet has established itself as a reputable platform with generous bonuses and benefits. Inexperienced players can rest assured because Hard Rock Bet offers up to $100 cashback if your first bet loses.

Furthermore, the Loyalty Rewards program, featuring 6 tiers (Member, Bronze, Silver, Gold, Platinum, and Diamond), lets you earn redeemable points for extra perks like mystery wheel spins, points multipliers, and Daily Odds Boosts. Players are automatically enrolled in this program after signing up. You can even receive discounts for Hard Rock Cafes, Hotels, and Rock Shops.

The payout structure is game-specific. High RTP slots like 88 Fortunes (96% RTP) provide consistent returns over time, while progressive jackpots (featured in games like Divide Fortune) offer massive payouts that can reach 6-figure sums.

The platform provides the following gaming options for players to choose from:

Sportsbook: It covers sports like football (NFL, NCAA), basketball (NBA, college), baseball (MLB), hockey (NHL), tennis (ATP, WTA), and more. Betting options include moneyline bets, point spreads, over/under (totals), prop bets, and parlays.
Casino games: Hard Rock Bet offers slots, table games (blackjack, roulette), keno, etc. Notable titles with high RTP percentages are Gonzo’s Quest and 88 Fortunes.
Special games: Aside from popular types like slots and blackjack, the casino also features exclusive games not found elsewhere. An example is Hard Rocking Reels, a slot game developed specifically for Hard Rock Bet to resonate with the brand’s rock-and-roll heritage.

Golden Nugget

Golden Nugget is famous worldwide, especially in the U.S. (Source).

As one of the best online casino sites in 2025, especially in the U.S., Golden Nugget delivers over 1,500 titles to cater to varying player preferences:

Table games: A variety of classic table games are available, such as Blackjack Blazing 7’s (traditional blackjack with side bets) and Casino Hold’em (players competing against the dealer)
Live dealer games: For the best experience, Golden Nugget provides live dealer options, including Live Dealer Roulette (real-time interaction) and Live Dealer Blackjack (playing blackjack with more than one table limit).

The chance of high payouts at Golden Nugget is high due to the high RTP percentage. For example, 88 Fortunes has an RTP of 96%, while Blackjack Blazing 7’s offers 99.33%.

Players also have access to attractive bonuses and promotions, including a Welcome bonus, Refer-a-friend, and Game of The Week. For the latter, a specific game is highlighted for each week, allowing you to earn double Golden Points (10 points per $100 wagered).

PlayStar Casino

Launched in New Jersey in August 2022, PlayStar Casino has quickly established itself as a solid player. In its first year alone, PlayStar secured a $15 million investment from the Glitnor group and acquired a 37.5% ownership stake over time, according to Next.io.

Below is a list of its gaming options:

Slots: PlayStar features over 300 titles of high RTP slots and progressive jackpots, such as Starburst and Lucky Ace.
Table games: Players enjoy popular table games like blackjack and roulette, both the traditional versions (such as Classic blackjack) and modern variants (e.g., American Roulette).

Slingo: As the name suggests, Slingo combines slots and bingo to appeal to a broader audience. Titles to consider are Book of Slingo, Slingo Starburst, Slingo Bells, and more.

PlayStar Casino offers a high potential for substantial payouts across all of its games. The most famous example is Ultra Blazing Fire Link (a progressive jackpot game), whose maximum jackpot exceeds $7 million. Hence, a $5 bet potentially yields a multimillion-dollar payout if the progressive jackpot is hit.

Besides basic bonuses, the PlayStar Club loyalty lets players earn extra as they advance through five levels: Level 1, Level 2 (250 points), Level 3 (1,000 points), Level 4 (4,000 points), and Level 5 (VIP).

Since its foundation, BetMGM has frequently offered huge payouts to its players. In fact, the total sum for its progressive jackpots amounted to more than $100 million in 2022 [BetMGM]. Plus, in table games like BetMGM Blackjack Pro, a $0 bet potentially yields up to $200 if hitting a natural blackjack, considering the standard 3:2 payout ratio.

In terms of bonuses, BetMGM offers all the basics along with the “Golden Wheel,” a daily spin feature. Each spin gives you substantial rewards, such as cash prizes, sports profit boosts (up to 100%), live casino chips for games like Crazy Time or Speed Blackjack, and more.

Bovada

Bovada offers a variety of games with responsive customer support (Source).

Bovada Casino operates under a license from the Curacao eGaming Commission. Players around the world, particularly in the United States, appreciate its user-friendly interface and responsive customer support.

The platform provides all the popular casino games for mobile and browsers (blackjack, roulette, poker, slots), along with special features and variants:

Exclusive slot games: Bovada provides proprietary slot titles with exclusive features unavailable elsewhere, such as “Gorgon’s Stash” (which immerses players in ancient Greek mythology) and “Sweet Fruits” (offering up to 100 paylines and potential payouts up to 3,000x the wager).
Bonus buy slots: You have the option to purchase access to bonus features (e.g., free spins and respins) directly without waiting for them to trigger during regular play.
Hot Drop jackpots: On Bovada, the Hot Drop jackpot features three progressive jackpots to increase your chance of substantial payouts: Hourly jackpot (every hour), Daily jackpot (every 24 hours), and Epic jackpot (no specific timeframe).

This casino offers prompt payouts, especially when you use cryptocurrencies. A typical Bitcoin withdrawal is processed within just 24 hours, which allows players to gain quick access to their winnings.

Bovada also offers a Bitcoin Welcome bonus, meaning players depositing with Bitcoin receive a 125% match bonus up to $1,250 on each of their first three deposits. That amounts to a total of $3,750.

JackpotCity Casino

Since its 1998 establishment, JackpotCity (licensed by the Malta Gaming Authority and the Kahnawake Gaming Commission) has earned the trust of jackpot fans worldwide.

Notable jackpot games include Jackpot City Gold Blitz (which features 4,096 ways to win unique card rewards) and Mega Millionaire Wheel (offering daily jackpot opportunities up to $1 million). Plus, players have the option to use two special game features:

Bonus Wheel: This feature allows registered players to spin a bonus wheel every four hours, offering opportunities to win valuable prizes like free spins, loyalty points, bonus credits, and more.
Must Win Jackpot series: The series rebrands existing slot games (9 Masks of Fire, Fire Forge, etc) to include special jackpot features, such as Daily Jackpot and Rapid Jackpot, to give players extra winning opportunities.

According to eCOGRA, the average payout percentage across all JackpotCity games is 93.88%, which indicates a favorable return to players. Notably, in April 2020, a Canadian player won CA$16,496,347.95 at JackpotCity Casino during the country’s lockdown.

Additionally, the casino features a comprehensive loyalty program with six tiers (Bronze, Silver, Gold, Platinum, Diamond, and Prive). As players progress through all six tiers, they potentially unlock extra benefits such as personalized bonuses and faster withdrawals.

Bet365

Bet365 boasts over 90 million users worldwide [Next.io] and won the EGR Operator Awards in 2017 for its sports betting quality [EGR].

Its game portfolio features common casino games along with other special experiences, such as:

Live dealer games (localized features): Bet365 Casino co-operates with Evolution Gaming and Playtech Live to provide exclusive tables catering to high rollers. Notable titles include “Super Spin Roulette” (with multipliers boosting winnings up to 540x the stake) and Bet365 All Bets Blackjack (allowing multiple side bets).
Bet365 originals: The 8 Immortals Series includes unique storylines (e.g., 8 Immortals: Awaken the Dragon) and features exclusive to Bet365, such as Free Spins Pick-Me Bonus, Both Ways Pays, Sticky Wild, etc.
Sports betting: Bet365 imposes maximum payout limits that vary by sport and competition. For top-tier football leagues, such as the English Premier League, the maximum payout is set at £2,000,000 (about $2,500,000), which is among the highest in the industry [The Punters Page].

There’s the Mega Mystery Bonus that gives players the opportunity to win cash prizes from a substantial prize pool. Specifically, players participate in eligible games during promotional periods of the Mega Mystery Bonus (such as Cash Collect Roulette and Spin A Win).

The prize pool is equally divided among all qualifying players for that round. For instance, each player receives $35 (out of a $3,500 prize pool) if 100 players meet the criteria.

We have just covered the 8 best online casino sites based on our research. Let’s discuss our review process in more detail in the next section.

Customer support: The responsiveness and professionalism of support teams through the live chat, email, and phone options.

Our reviews are based on thorough casino comparison and casino ratings from user feedback for more objective perspectives.

Ongoing promotions and bonuses also play a significant role in our evaluation process. So, let’s discuss the top casino bonuses offered by leading online casino sites in the next section.

Top 4 Casino Bonus Types

The top 4 casino bonus types include No Deposit bonus, Reload bonus, Cashback bonus, and High Roller bonus, each with their respective advantages (e.g., no deposit required, VIP benefits).

No Deposit Bonus

This bonus gives you free money or spins just for signing up. For example, popular slot games like Starburst give new players 20 free spins after they log in for the first time. You play and win real money without depositing anything.

Reload Bonus

A reload bonus rewards you for adding more money to your account after your first deposit.

For example, the casino offers a 50% reload bonus; that means when you deposit $50, they add $25 extra to your account. You have $75 in total to play games with.

Cashback Bonus

Cashback bonuses give you a percentage of your losses back, either as real money or bonus credits. It’s a safety net for when luck is not on your side.

Suppose you lose $100 over the weekend, and the casino has a 10% cashback offer. $10 is returned to your account as a result to soften the blow.

High Roller Bonus

Lastly, this bonus is for players who deposit and play with large sums of money. It’s bigger than other bonuses (like cashback or reload) and often comes with exclusive perks other than money, such as merchandise or VIP rewards.

Here’s an illustration: you deposit $2,000 to a casino game with a 100% high roller bonus. You get an extra $2,000 and have $4,000 in total.

Read reviews and recommendations on PeakyCasino if you are unsure how to find online casino sites with the best bonuses. Our research team has carefully evaluated the bonus offerings of each casino, including wagering requirements, game eligibility, cashout limits, etc., so you know exactly what to expect.

Bonuses aside, it’s also equally important to choose a high-payout casino to place your bets. After all, even the most generous 150% bonus means little if the payout is not up to your expectations.

What Is A High Payout in Casinos?

A high payout refers to the percentage of money (wagered by players) that the casino pays back in winnings over time. It’s measured by a statistic called the Return to Player (RTP). The higher the RTP, the more money players can expect to receive back from their bets in the long run.

For example, a slot game in a casino has an RTP of 96%. That means that, on average, for every $100 wagered, the game pays back $96 to players; the casino only keeps $4 as profit.

Aside from high RTPs, a high payout casino must also have a fair, transparent withdrawal policy and not skew games heavily in their favor. To help you choose the best online casino site, PeakyCasino offers 6 insider tips as below.

7 Simple Steps to Choose The Best Online Casinos

To choose the best online casino, ensure it’s licensed by trusted regulators (e.g., Curacao eGaming) and support your preferred payment method securely. Look for games with high RTPs (at least 95%) and smooth usability.

Do your research and check their bonuses, payout rates, etc. (Source).

Choose Legal And Regulated Online Casinos

The first step is to ensure the platform complies with casino regulation and holds a license from trusted authorities (e.g., Curacao eGaming, Malta Gaming Authority).

To verify this information, check the bottom of the casino’s homepage or their “About Us” section for a license number. Then, cross-check it on the regulator’s official website to confirm its validity.

Keep in mind the country-specific information because the gambling laws by region vary a lot.

Check The Payment Options (Deposit & Withdrawal)

A reputable casino should support your preferred payment method while ensuring each transaction is secure and fast.

Look for options such as credit and debit cards, eWallets (like PayPal and Skrill), and even cryptocurrencies, depending on your preference. Plus, make sure the deposit and withdrawal processes are simple, with quick payout times (ideally within 24 to 48 hours) and minimal fees.

Research Their Bonuses and Promotions

Although bonuses significantly improve your playing experience, it’s essential to understand casino terminology, such as house edge and bonus terms and conditions.

First, they must come with realistic wagering requirements (between 20x and 40x). Secondly, the casino should offer other promotions regularly, like free spins, loyalty programs, monthly contests, etc. Confirm each bonus term is clearly stated, and avoid casinos with vague or overly restrictive conditions.

Review Payout Rates

As mentioned earlier, the payout rate is typically represented by the RTP percentage.

Aim for casinos that offer games with high RTPs (preferably 95% and above. Also, check if the casino’s games are audited by independent organizations like eCOGRA or iTech Labs, which certify the fairness and accuracy of payout rates. That way, you ensure the games are not rigged and give you a fair chance of winning.

Confirm The Usability

A user-friendly platform should let you navigate easily between sections like games, promotions, customer support, etc. They should also offer mobile casino apps for on-the-go gambling.

Pay attention to the site’s loading speed as well; it must load quickly without lag or technical issues. And don’t forget to try accessing the site on various devices (desktop, tablet, smartphone) and see how the interface adjusts to different screen sizes.

Evaluate Optional Criteria

Aside from the five main attributes, consider the following factors if desired:

Customer Support

Test the live chat feature with a simple question, such as “What are the withdrawal limits?” or “How do I claim my bonus?” Note how quickly they respond and whether the answers are clear and professional.

Community Engagement

A strong sense of community makes online gambling both enjoyable and more interactive. We suggest testing live dealer games to see if they include chat options and observe the interactions between the dealers and other players. Also, check the casino’s presence on platforms like Twitter or Facebook.

User feedback also gives insights into a casino’s trustworthiness. Read casino reviews & ratings on review sites like PeakyCasino for more information.

Responsible Gambling Tools

Lastly, a trustworthy casino promotes responsible gaming by offering tools to help you manage your gaming behavior, such as deposit limits, loss limits, session time reminders, etc. Also, see if the casino partners with organizations like GamCare, BeGamebleAware, or Gamblers Anonymous.

Choose The Casino You Want to Play

After carefully evaluating all the previous factors (legality, payment options, bonuses, etc.), it’s time to make an informed decision.

Select the casino that best aligns with your preferences. Before committing, though, read through user reviews and testimonials to gauge other players’ experiences. Once you have made your choice, visit the casino’s website, go through the registration process, and fill out your necessary personal information accurately.

Once you’ve chosen an online casino, the next step is to find a game that matches your strengths and personal preferences. Below are the top 5 most popular online casino games to consider.

5 Top Online Casino Games

The 5 top online casino games are slots, blackjack, roulette, baccarat, and poker. Their traditional versions are popular, but players have the option to try modern variants like progressive jackpot slots, French roulette, three-card poker, or Chemin de Fer.

Slots

In a slot game, you spin reels that display different symbols (e.g., cherries, stars, lobsters, etc.). To win, specific symbols must align in a predefined pattern called a “payline.”

A payline can run horizontally, vertically, or even diagonally across the reel. Let’s say a slot has a payline that requires three matching symbols in a row on the middle row of the reels. That means you win when you land three cherries in that exact pattern.

Popular variants include Progressive Jackpot Slots, like Mega Moolah. They have a jackpot prize that grows every time someone places a bet, even reaching millions. The jackpot can be triggered randomly or by hitting a specific combination.

Blackjack

For this card game, number cards are worth their face value, face cards (Jack, King, Queen) are worth 10, and Aces are either 11 or 1.

You start with two cards and choose to “Hit” (take another card) or “Stand” (keep your hand). The dealer also plays as well. You win if your hand’s total is higher than the dealer’s and doesn’t go over 21.

Another common version is Spanish 21, where all the 10-value cards are removed to make it harder for players to get a hand. In compensation, this variant adds bonus payouts for special combinations (e.g., a 5-card hand totaling 21) to make the game more exciting. You can apply the same blackjack strategy for both types.

Roulette

You bet on where the ball lands (Source).

Roulette players bet on where a ball lands on the spinning wheel. Specifically, the wheel has numbered pockets (1 to 36) in red or black, plus a green pocket for 0 (and sometimes 00 in American Roulette).

Players have the option to bet on specific numbers (e.g., 18), groups of numbers (18 and 24), colors (red), or whether the number will be odd or even. The dealer spins the wheel and drops the ball, and you win if it lands in a pocket matching your bet.

People also like French Roulette, a variant with an extra rule called “La Partage.” When you bet on even-money bets (like red/black or odd/even), and the ball lands on 0, you only lose half your bet instead of all of it.

Some popular roulette strategies include Martingale, Paroli, and D’Alembert.

Baccarat

In baccarat, you bet on one of three outcomes: the Player wins, the Banker wins, or it’s a tie.

Both the Player and Banker are dealt two cards, and the hand closest to 9 wins. Cards 2-9 are worth their face value, face cards and 10s are worth 0, and Aces are worth 1. However, only the last digit counts if the total exceeds 9 (e.g., a hand of 7 and 6 equals 13, which counts as 3).

Aside from traditional baccarat, there’s a popular European variant called Chemin de Fer. Players take turns acting as the Banker and play against other players instead of the casino. The goal is still the same: have a hand total closest to 9 to win.

Poker

Players have to form the best hand when playing poker (Source).

Poker is a card game where players compete to form the best hand or convince others to fold.

The most common version is Texas Hold’em. Each player gets two private cards (cards that only this player can see) and uses five community cards (visible to everyone) to make the best five-card hand. Rounds of betting take place as more community cards are revealed. Players win if they hold the best hand at showdown or are the remaining one after others fold.

Meanwhile, another beginner-friendly variant, Three-Card Poker, is simpler and faster than Texas Hold’em. Here, you only play against the dealer, and both of you are dealt three cards. The goal is to have a better hand than the dealer, with extra payouts for certain hands (e.g., straights or three-of-a-kind). One of the most effective poker tips is to fast-play your strong hands to build the pot.

Despite their popularity, it’s important to remember that these games still carry risks. Let’s discuss six essential tips to help you gamble safely and responsibly.

6 Tips For Responsible Gambling

To promote responsible gaming and prevent gambling addiction, keep in mind the following tips:

Set a spending limit: Decide in advance how much money you can afford to lose. Then, stick to that limit, regardless of whether you are winning or losing.
Understand the games: Take time to learn the rules and odds of the games you play. That way, you make better decisions and set more realistic expectations.
Avoid chasing losses: Accept losses as part of the experience. Never gamble more in an attempt to recover lost money unless you want to face a huge financial risk.
Use self-control tools: Online casinos offer tools like deposit limits and self-exclusion options to help manage your gambling habit. Take advantage of them when needed.
Take breaks and stay balanced: Don’t let gambling consume your time. Schedule regular breaks and balance gambling with other hobbies or activities (e.g., writing, playing sports).
Seek help if needed: Reach out to support organizations and problem gambling resources like BeGambleAware and GamCare if you feel you are getting out of control.
