Popular online casino slots types

At any top US online casino there are plenty of slot games to choose from. Real money slots range from the classic three-reel games based on the very first slot machines, to colorful and feature-packed video slots that come with bonus wheels and games, animations, and exciting new ways to win. Take a look at the online slot varieties below for an introduction to the main types of real money slots online.

Three-reel slots

Online slots by highest RTP in 2024

The following titles represent the highest payout slots games available at casinos online. This payout figure means the amount you would win back from your bets over a long period, though shorter term results are a lot more variable.

A benefit to you is the cut the casino takes in fees is the lowest with these titles. For context, the average payout on a slots game is 80%-95%.

  • 1
    Avalon II - 97%
  • 2
     Guns ‘n’ Roses - 96.98%
  • 3
     Thunderstruck II - 96.65%
  • 4
     Wheel of Fortune - 96.6%

What is a payout percentage?

As a slots player, the payout percentage tells you how much of your money bet will be paid out in winnings. This means you can work out how much you could win on average. For example, if a slot game payout percentage is 98.20%, the casino will on average pay out $98.2 for every $100 wagered. This is also known as Return To Player (RTP). We outline the RTP for each casino we rate so you can find the payout percentage on a slot machine easily.

Slots strategy

Casino slots are entirely reliant on chance, but that doesn’t mean there aren’t things you can do to put yourself in a better position to win. Experienced players follow a distinct slot game strategy, like only playing games with the highest payout percentages, practicing their bonus rounds, and knowing their paylines inside and out. Follow these guides to give yourself the best possible chance to win jackpots on slot machines online.
