Best Online Slots for Real Money - April, 2024

In the United States, online gambling laws are regulated on a state-by-state basis, with some states allowing online gambling while others do not. As of April, 2024, there are currently four states where online casino gambling, including online slots, is legal and regulated: Michigan, New Jersey, Pennsylvania, West Virginia, Connecticut, and Delaware. Online casinos are expected to debut in Rhode Island during the first half of 2024. Some other states, such as Indiana, have considered legalization in recent years, but nothing has come of it yet. There's also been a push in other states as sports betting tax revenue disappoints relative to expectations, but there's nothing imminent as of now.

While online slots are legal in some states, they are still subject to strict regulations to ensure the fairness and security of the games. Online casinos must be licensed and regulated by state gaming commissions, and the games themselves must be audited and tested by third-party organizations to ensure that they are fair and random.

Online slots in the United States have become increasingly popular in recent years, particularly as more states have legalized online gambling. Online slots offer a convenient and accessible way for players to enjoy the excitement of casino gaming from the comfort of their own homes. Additionally, the graphics, animations, and bonus features of online slots have continued to improve, making them more engaging and entertaining for players. There are hundreds of different options, with all kinds of different types of themes and jackpots available to users.

Overall, the state of online slot machines in the United States is evolving, with more states legalizing and regulating online gambling. As technology continues to advance and online gambling becomes more mainstream, it is likely that online slots will continue to grow in popularity and become an even more prominent part of the US gambling industry.

Which Online Slots Should You Play?

Like in sports betting, there isn't necessarily a consensus "best slot machine" because what makes it the best may differ from person to person. But here are some of the factors to look at.

• RTP: Short for "Return to Player" percentage, it's the percent out of 100% that goes back to the player. The higher the RTP, the more users will win over time, though there will be big swings in small samples.
• Volatility: On some machines, you'll win more often, but have lower upside for big scores. On others, you'll win infrequently but have the upside for big payouts.
• Complexity: Most non-slot players think of slots with three reels, and you need to hit three "7s" to score a jackpot. Not anymore. Online slots have thousands of potential payout combinations, and if you're not an experienced player, you may not even know what you're looking at.
• Theme: Whether or not you want to believe it, the visual look and feel of a slot machine matters to many users.
• Bonus rounds: Some users like to build toward free spins and bonus rounds, while for many others that's not important.

Pay Table

A pay table is an on-screen guide to the number of paylines, bonus features, betting requirements, winning combinations and more. The contents of a pay table are listed below:

• Game Description: Whether Egyptian-themed or game show style, a short description of your slot is provided when you click on the information “i” icon.
• Game Rules: The newest slots have a complex set of rules about how to play the game.
• Scatter Symbol: Scatter symbols can appear anywhere on the reels. The symbols don’t have to land in a straight line.
• Wild Symbol: Stands in for any symbol to complete a winning combination.
• Bonuses: A certain number of bonus symbols trigger a bonus game where you have the chance to win large sums of money.
• Multipliers: A special feature that multiplies your winnings up to 10,000x on some online slots.
• Free Spins: The number of extra spins you win is based on the outcome of the bonus round.
• Jackpots: Find out what’s required to qualify for a jackpot. See if the slot offers multiple jackpots, and what the payouts are.
• RTP: Some pay tables include the return-to-player percentage. Improve your odds by avoiding games with RTPs below 96%. 

Slot Strategy

Slot machines are programmed to payout less than they take in. They’re random, so a player can’t influence the outcome of a spin.  Apart from playing slowly, the best thing he can do to minimize his losses is to play at the highest denomination possible. Penny slots see the most action despite their low return of around 90%. In contrast, the RTP of a $1 slot is typically above 95%.

Knowing which games to avoid will improve your chances by a few percentage points. For instance, studios charge royalties for branded slots based on celebrity chefs, popular game shows and more. But software developers aren’t absorbing the added expense. Instead, it’s being passed on to the gambler.

Progressive slots also tend to have lower RTPs than standard ones, but some players say they’ll sacrifice higher returns for a bigger payday. While you're less likely to win, a jackpot on a progressive slot can be upwards of $2 million.

Should I Bet Max?

Some slots, progressives, in particular, require players to bet max to be eligible for the highest return. However, it’s not advisable to do so if there’s no benefit in making the maximum bet. Be sure to bet enough to qualify for free spins and bonus rounds.

Online Slot Revenue

Total revenue from online slots eclipses every other game in the casino, according to the February 2023 United States iGaming Revenue Report. Last year, online slots in Pennsylvania brought in $92.8 million. It’s not hard to explain the overwhelming success of online slots. Typically, a player’s first gambling experience is on a slot machine. Slots require no skill and are a single-player game. Also, slots provide the potential to get filthy rich off a tiny $0.50 bet.  Online slots appeal to the majority of gamblers, and the rest typically try their luck at video poker or table games.

Conclusion

Online slots come as one of the most entertaining options at casinos. You can play with any bankroll or skill level. The only thing you'll need is luck.

Test out certain games in demo or free play. Get a sense of where your bankroll may work best.

Play slots that offer free spins and bonus rounds. For some games, you might increase your chances of winning with max bets.
