As the digital revolution continues to change everything we thought we knew about entertainment, it is becoming clear that no sector or industry is emerging unscathed. Chief among these is the casino industry, which is rapidly becoming a predominantly online affair.

Online casino revenues in the US have been growing at double-digit figures over the past five years and are predicted to continue doing so for the foreseeable future, as more and more Americans choose to gamble on the go with their smartphones and tablets.

Of all of the casino games out there, slots remain the most popular. There are tens of thousands of different slot titles out there, some of which boast immersive 3D graphics and, perhaps more importantly, six or even seven-figure jackpot payouts.

However, not all slot games are created equal. There are some that offer superior gameplay, superior bonus features, and superior prizes. Read on to find out the very best online slots that US gamblers should be playing right now.

Starburst

Starburst is probably one of the single most iconic and popular slot games in the world right now and has been for almost a decade. Launched in 2012 by the Swedish game developer NetEnt, this neon-soaked 5-reel game is a thoughtful nod to the most iconic arcade games of the 1980s. Think space lasers, technicolor jewels, and a truly unbeatable chiptune soundtrack.

Despite having been released so many years ago, this game remains one of the top free US online slot games at slots.info, where American gamers flock to try out the hottest slots for free. Starburst's enduring success is partly due to the simple fact that you can't beat the classics, but it doesn't hurt that the top prize can be as much as $5 million from a single spin. What's more, with an RTP of 96.01%, this is a game that works for high rollers and low-risk players alike.

Game of Thrones

Give that the HBO fantasy series Game of Thrones is the world's most successful TV show in history by virtually every measure, as per time.com, it was only a matter of time before someone released an official GoT branded slot game. Fortunately, this popular slot by Microgaming manages to live up to the hype of the TV show.

It's a 5x3 slot that gives you the option to customize every aspect of your game, allowing you to set betting limits and wager anything between 30 cents and $15 per spin. From here, step into the shoes of one of the show's most popular characters and attempt to line up the reels and win the hidden treasures from the houses of Baratheon, Lannister, Stark, and Targaryen.

Gonzo's Quest

Gonzo's Quest is truly a slot like no other and will always make the news. It's an immersive slot that puts you into the shoes of Gonzo the explorer, as he explores the Andes in search of the mythical lost city of El Dorado. With a maximum payout worth 50,000 times your original wager, it's no wonder that this is one of the most popular slot games in America.

True to its mountainous theme, Gonzo's Quest offers multiple chances to win with its celebrated 'avalanche' feature, which randomly triggers cascading wilds that replace all winning symbols with new ones, allowing you to multiply your jackpot several times over.

Golden Goddess

Step into the wealth and power of the Ancient Greek world with the acclaimed Golden Goddess slot from IGT. Goddess, hero, pegasus, and dove symbols are the ones to watch on the 5-reel slot game, as racking any number of these on the paylines can trigger a cash payout worth $20,000 from a single spin.

This game features stunning 3D graphics that run seamlessly on iOS and Android, as well as a wide array of bonus features such as wilds, multipliers, and cascades. Golden Goddess is a classic slot that sticks to the fundamental features that players know and love, which is exactly why it remains so popular after all these years.

Lara Croft: Tomb Raider

The video game icon Lara Croft, as covered by businessinsider.com, is a character that grew to global fame by pillaging the lost tombs and hidden temples of the ancient world for unimaginable riches. It is therefore fitting that she would take on a new lease of life as a character in a smash-hit slot game. The official Tomb Raider slot from Microgaming contains all of the features that fans of the original game series will love, including the music, artifacts, and Croft's soothing upper-class English drawl.

The real reason to stick around, however, is the prizes on offer. Randomly triggered bonuses can occur at any point during the game, awarding you with dozens of free spins, multipliers that will boost your win by 75x, or just pay an instant cash bonus. What's not to like?
