Best Online Slots: Top US Titles to Play in 2023

When it comes to the best online slots, a few titles tick all the right boxes for US players. Read on to get the lowdown on the five crème de la crème.

5 Best Online Slots to Spin Today at Top US Gambling Sites

If you’re after the best online casino slots, US-facing gambling sites have enough to keep you playing for hours on end. If you want to keep it old-school, class three-reels will do the trick. Modern titles run the gamut from progressive to multi-pay line slots packed with bet-ways and innovative features like cascading reels, bonus rounds, stacked wilds, and free spins.

The majority are provided by software heavyweights. We’re talking top-tier developers, such as NetEnt, RTG, and Evolution Gaming. We’ve done the legwork and rounded out the five best online slots. They grace the game lobbies of top US online casinos like DraftKings, BetMGM, Caesars, Fanduel, and Betrivers.

1. Sweet Bonanza by Pragmatic Play

Pragmatic Play is a staple of most US online casinos, most notably BetRivers and BetMGM. The software provider has churned out some of the most popular slots, but Sweet Bonanza is the cherry on top. Like other sister titles like Wild Wild Riches and Big Bass Bonanza, the slot has an All Ways engine under the hood, with a medium to high variance and max wins up to 21,175 x your stake.

Its potential payout rings up to $2,625,000 off the back of a decent payback percentage. However, Cluster Pays put Sweet Bonanza right up top among the best online slots for US bettors.

Gameplay, Features, and Playability of Sweet Bonanza

Sweet Bonanza sports a Candyland theme. The backdrop features frosting, cakes, and other confectionery favorites that marry well with the sharp graphics. You’ll love that the soundtrack is immersive and doesn’t disrupt the gameplay.

This medium to high-volatility game is among the best slots online for its bevy of rich symbols. At the high end of the payout spectrum, you’ll find candies that run the gamut from Purple Squares to Red Hearts. Fruits like Plumb, Watermelon, Apple, and Banana are awkwardly included among symbols.

Gameplay – Sweet Bonanza plays out on a 6×5 reel built on the Pragmatic Play’s All Ways payline system. This adds a unique touch to the gameplay. That is especially true when coupled with its Cluster Pays payout format. The winning symbols don’t have to align into a specific shape to trigger a payout.

With Cluster Pays, you can get paid when eight or more identical symbols land anywhere on the screen. The winning symbols will go puff, and new ones will cascade from the top of the screen. That’s the beauty of Sweet Bonanza’s Tumbling Reels design. You can trigger the cascading reels multiple times and land stacked wins from a single spin.

Bet Range – Versatile is the name of the game when it comes to betting limits on this slot game. You can wager anywhere from 20¢ to $125 a spin. With high variance, Sweet Bonanza is among the best online slots for high-rollers looking to make bank. If Lady Luck dances in your favor and you activate the Free Spins feature, you can rake in up to $2,625,000 in payouts.

Playability

Sweet Bonanza sweeps the entire screen when you play on a desktop. This immerses you in the Candyland theme. When you transition to a horizontal mobile format, the buttons are somewhat tiny on the small screen. The real magic happens in the vertical layout on mobile apps and browsers. The HTML5 under the hood really shines through and fits on any mobile device.

Sweet Bonanza Comes with Decent RTP and Odds

Ante Bet, Tumble, and Free Spins features make Sweet Bonanza one of the best slots online. It packs a 96.49% RTP, and the odds are so-so. Pragmatic Play offers lower odds and an RTP of 95.45% on some gambling sites.

Tips to Increase Your Odds of Winning at Sweet Bonanza

The 96.49% payback percentage isn’t too shabby. However, you boost your chances of winning by covering all (if not most) pay lines. Of course, it pays to watch your bankroll. It’s best to start small and increase your wagers as you get the hang of it.

Keep an eye out for features that pay big, like candy bomb multipliers and tumbling reels. You’ll be better off skipping the ante bet, as it increases the house edge.

2. Buffalo Gold by Aristocrat Gaming

Aristocrat’s Buffalo Gold brings a riot of good payouts, features, and action. It’s based on the highly popular slot machine found across land-based casinos. This video title is among the best online slots at most US casino sites (think BetMGM, BetRivers, and Caesars Online Casino).

Buffalo Gold Immerses with a Simple Gameplay and Impressive Features

A five-reel slot, Buffalo Gold features up to 1024 ways to bet. The simple gameplay and high payouts speak to its notable features. Multipliers, wilds, free spins, and a bonus game where you can double your payout. You can tailor your bets with the Xtra Reel Power feature.

Gameplay – Xtra Reel Power is at the core of Buffalo Gold’s gameplay. It plays out on a 5×4 reel bed, and credits help you unlock the maximum 1024 pay lines. In the traditional format, you need 40 credits to unlock all five reels. You can select your stake per reel from there to get the total wager.

High-paying symbols pay homage to its American wildlife theme. The titular buffalo triggers the 12,000x payout if you land three or more on the payline. Stags, wolves, puma, and eagles join traditional card symbols (10, J, Q, K, and A).

Winning symbols pay from left to right. That’s a flight from Pragmatic Play’s Buffalo King slot that offers 4096 bet-ways across six reels. Unlike the latter, Buffalo Gold is among the best online slots real money with medium variance.

Bet Range – You can wager as little as 1¢, with a max bet of $50 per spin. The free spins feature activates when you land 3+ gold symbols. That’ll give you eight free spins, while 4 and 5 spins reward you with 15 and 20 bonus spins, respectively.

Buffalo Gold on mobile

The slot is ready-made for tablets and smartphones with its uncluttered interface and understated graphics.

Buffalo Gold has Good Odds and RTP.

For a casino classic, Buffalo Gold offers pretty impressive odds. Its 96% RTP is worth writing home about.

Playing Tips: How to Improve Your Odds at Buffalo Gold

Buffalo Gold sits smack dab in the middle of the pile, setting it up to become one of the best online slots out there. The simple gameplay doesn’t get in the way of getting decent payouts. Much like NetEnt’s Starburst, the key is to cover all pay lines to increase your chances of triggering free spins.

3. Starburst by NetEnt

Starburst is one of NetEnt’s best online slots, and for good reason. It’s a cult favorite with a cheerful, fruity theme with just ten paylines across five reels. With the win-both-way feature, you can double paylines and win up to 50,000x your stake.

Stunning Graphics, Simple Gameplay, and Great Features on a 5×3 Grid

Gameplay – NetEnt used a less-is-more approach to Starburst’s gameplay. It takes a retro twist from Arcade games with ten standard paylines across three rows and five reels. The Wild Symbol system gives you a win-both-ways with a left-to-right payout. That means you can double the paylines to 20.

Watch out for expanding Wilds that land on the 2nd, 3rd, and 4th reels. They’ll balloon and fill the whole screen, activating the free spins feature. If you hit five Wilds, you can land 50,000x your stake.

Bet Range – Starburst ticks all the right boxes for the best online slots. You wager from 10¢. The max bet is $100.

Starburst plays great on mobile

The bright and bold symbols really shine on the small screen. All gameplay features transition well to tablets and smartphones, especially in landscape mode. You don’t have to download any software.

Starburst RTP and Odds

Let’s face it; even the best online real money slots don’t offer great odds. Starburst makes up for that with stacked wilds that can push your wins to 50k. It helps that the RTP is pretty decent at 96.1%, with up to 20 ways to bet.

Handy Tips for Playing Starburst Slot

Starburst is a low-variance slot. That means your best bet is to stick to good bankroll strategies to wait out for the Wilds feature.

4. Cleopatra by IGT

IGT’s Cleopatra has been one of the best online slots since 2012. With an ancient Egyptian theme, the title comes in an assortment of flavors. The most popular titles in this series include Cleopatra Gold (95.97% RTP) and Cleopatra Plus (96.5% RTP). Both sport five reels with either 20 or 40 paylines.

Gameplay and Features: How to Play Cleopatra Slot

The standard Cleopatra slot has a fixed jackpot that pays out 10,000x of your stake. It offers max payouts of 100,000 your wager. The volatility is high-end to make the game feel like a challenge. It features a generous multiplier and free spins.

Gameplay – Most of the best online casino slots imitated the original Cleopatra. Its gameplay should be pretty straightforward. Hieroglyphics make up the high-paying symbols that include the Eye of Horus and scarab beetles. You’ll also encounter bejeweled and golden card symbols 10, J, Q, K, and A.

Cleopatra herself is the most prized symbol, as it doubles your win if it sits for a symbol. Keep an eye out for the re-spin feature and a 3x multiple. You can get 15 free spins in the bonus round.

Bet Range – Cleopatra’s betting range may differ depending on where you play. At BetMGM, you can wager 20¢ up to $200 per spin. Caesars Online Casino takes it up one notch, allowing bets up to $500 per spin.

Cleopatra slot on mobile

Cleopatra is one of the best online casino slots for its understated graphics. The game fashions out well for the small screen, as well.

Cleopatra Odds and RTP

Cleopatra is a medium-variance slot but leans more heavily toward frequent wins. The odds are so-so, with a healthy RTP of 95.03%. The Cleopatra Plus version gives better odds at 96.5% RTP.

Tips for Playing Cleopatra Slot

Nothing really jumps at you with Cleopatra. If you guard your bankroll with breaks in between plays, you’re set to enjoy the experience. However, it’s best to play with maximum credits and cover all paylines to boost your winning chances.

5. Gates of Olympus by Pragmatic Play

Pragmatic Play crafts some of the best online slots, and Gates of Olympus is right up top. The video slot features an hourglass, crowns, and rings on a 6×5 layout. Like Sweet Bonanza, it incorporates Tumbling Reels with multipliers that can rack up your wins by up to 500 times.

Gates of Olympus Features and Gameplay

Gameplay – The slot is played on a five-row, six-reel grid with an All Ways system under the hood. The symbols don’t have to form a traditional shape to trigger payouts. If eight or more matching symbols land anywhere on the screen, you’re good for a win.

Bet Range – This Greek Mythology-themed slot allows you to wager between 20¢ to $100. Some US online casinos like Caesars and BetMGM offer higher betting limits on Gates of Olympus.

Gates of Olympus is mobile-friendly

The slot has a responsive design that adapts to your device. You can play on any tablet or smartphone.

Gates of Olympus Odds and RTP Matches Starburst

If you’re looking for an alternative to NetEnt’s Starburst, Gates of Olympus will fit the bill. It boasts a 96.5% RTP. As one of the best online real money slots for high volatility, it pays out big wins less often.

Tips for Playing Gates of Olympus

Being a high-variance slot, Gates of Olympus calls for smaller wagers. If you bet big, you’ll likely bleed your bankroll in no time. Think of it as a long game, with the free spins feature being your target. It can amp up your win by up to 500x.
