How Our Experts Rank The Best Online Casinos

The LINEUPS.com team takes a few features into account when ranking the top real money casino sites. Game variety is one of the top factors, as iGaming fans generally look for a large collection of games to choose from, especially when it comes to online slot machines.

Another major factor for fans of online casinos is the quality of the mobile app/desktop site. An interface needs to not just be aesthetically pleasing, but also easy to navigate. Additionally, the speed of the online casino app should be taken into account, as bettors won’t want to wait too long to start betting.

Return to player (RTP) is another major factor when signing up for an online casino app. RTP is basically a calculation of how much money can be won on average with a table game or online slot machine over a period of time. So for example, an operator might test a slot machine game with thousands of spins before determining RTP.

One of the most popular online slot machines is Blood Suckers, which has a 98% return to player percentage. So for every $100 played with the slot machine, online casino fans can expect around $98 back.

Top Online Casino Games

Online Slots in U.S.

Plenty of online casino fans focus primarily on online slot machines. And this makes plenty of sense, as there are hundreds of slots to choose from, with each showcasing a unique design. Some of the most popular slot machine games available on different platforms are Gold Blitz, 88 Fortunes, Capital Gains and Hypernova. Progressive jackpots are also available, which give users a bigger overall payout.

Roulette is another top online casino game. Like blackjack, there are numerous ways to play roulette outside of the standard game. Many bettors enjoy playing European roulette, first-person roulette, American roulette and even live dealer roulette.

Video Poker

A classic at any casino bar, video poker is widely available with different iGaming apps. There’s plenty of variety in terms of video poker games, like Ultimate X Poker, Draw Poker and Game King.

Caesars Casino Video Poker


Rounding out the classic casino games is craps. While it has plenty of fans, it isn’t as widely available in the iGaming market as other table games. As is the case with roulette and blackjack, bettors can play live dealer craps.
