Online casinos have become one of the most popular forms of entertainment online in recent years. The online gaming market in the United States was worth an estimated $19 billion in 2023, an increase of 23% over the preceding year. While these figures include all forms of online gaming – including sports betting – sweepstakes casinos alone have seen a huge growth in recent years. This market has grown in leaps and bounds, being a legal way to play casino games in the U.S. with the prospect of winning real cash prizes.

Most Popular Online Casino Games

We wanted to find out the most popular online casino games, based on global online casino gaming data from 2023, and so we asked the latest version of ChatGPT to break down the numbers. The results will probably not be a major surprise to those familiar with online casinos, but here is how they worked out:

As might be expected, online slot games make up the vast majority of online casino gaming play. The immense variety and quantity of slots out there makes them the clear winner when it comes to the most popular online casino games.

Of the other traditional casino games to appear in our results, blackjack was the clear winner of the table games. The familiarity with this game along with the potential use of strategy to maximize winning opportunities makes blackjack more than twice as popular as any other classic casino game. Roulette comes second, with this 18th century game still proving a winner in the digital age. Casino poker takes 3% of the market share while baccarat and live dealer games account for around 1% each.

In the years to come we can certainly expect to see a growth in live dealer games, as different live gaming options come onto the market, while the less famous game of baccarat is likely to have the smaller market share. Dice games like Craps and Sic Bo don’t even make our chart, but again there is potential for growth of both of these games over the years to come.

Growth of Sweepstakes Casinos in the US

Many players in the US choose to play their favorite online casino games at Sweepstakes casinos, especially in States where real-money casinos are prohibited. We got the latest version of ChatGPT to analyze the data and it came up with the following estimates for the popularity of individual sweeps casinos in the States:

According to ChatGPT 4.0 McLuck remains comfortably the most popular social casino for American players. McLuck offers a huge range of games, regular bonuses and promotions and is universally trusted by players, making it top of the charts. WOW Vegas and Pulsz take the next two spots on our chart, with High 5, Vegas Gems and Sweeptastic also proving to be popular options.

Of course new social casinos come online all the time, and no doubt there will be some differences in the figures above in a year’s time, although McLuck will certainly be difficult to dislodge from the top spot.
