Selecting the best online slot sites

There are many factors to consider when evaluating a given online casino’s slots. Here are some of the more important ones you should keep in mind when deciding whether to play online slots at a particular online casino.

Number of slots

The number of slots at a given online casino can vary greatly. Some have less than 100 while others have more than 1,000 titles. Greater quantity doesn’t necessarily mean greater quality, but sites with more slots tend not just to offer more choices but also exhibit other advantages, such as better functionality and design.

Variety of slots

Some sites offer greater variety among their slots, providing lots of different ways to play. Spend some time looking through an online casino’s slot selection and note the different types of slots available, including:

• traditional three-reel slots (not as common online as live);
• five-reel or “video slots” (the most common type online);
• other variations like six- and seven-reel slots or other types made possible by the flexibility of online gaming;
• multi-line slots that offer different numbers of paylines (20, 30 and 40 paylines are common, but you’ll find some games with hundreds of paylines);
• penny slots

Progressive slots

Most sites offer slots featuring progressive jackpots, although again, you’ll find some feature “progressives” a lot more prominently than others. The size of the progressive jackpots can vary as well.

Different slot formats

Speaking of jackpots, you might also consider how many slots a site has that feature non-progressive or “fixed” jackpots. Look for other slot formats, too. For example, slot tournaments aren’t too common, but some sites do feature them.

Payouts and return to player (RTP) percentages

Every slot has its own return to player (RTP) percentage that represents the theoretical amount a player will win over time. Particular slots have the same RTP percentage regardless of the site. For example, you’ll find a popular slot like Starburst on many different sites, and no matter where you find it, the RTP is going to be 96.1%.

That said, some sites have more real money slots with high RTP percentages, and some have many with low RTP percentages. That will affect how often you win and your payouts, although remember these percentages represent only the average win and not exactly what you’ll win (or lose) each time you play.

Bonuses, promotions and free spins

Does your online casino feature lots of bonuses and promos awarding you with cash or casino credit with which to play slots? Does the site feature free spins bonuses? Again, some sites are more generous than others with such perks, so shop around.

Site design and functionality

In a lot of cases, game developers create the individual slots you play at online sites, and these games tend to look and play similarly no matter the online casino. Even so, some sites have better lobbies with different categories of games and other features and options arranged more intuitively.

Mobile apps

Most online casinos allow you to play slots either on your computer using a web browser or on a mobile app. The slots are optimized for your mobile device and often play just as well as on the computer, albeit with a smaller screen. One factor to consider, however, is that sometimes the app version of the site won’t have all of the slots available on the full web-based version.

Best online casinos with slots

Taking all of the factors listed above into consideration, we can particularly recommend the following four online casinos as the best slots sites.

Other online slots options

There are many more online casinos beyond these top four discussed above, including some currently available in multiple states. Other popular online slots sites include:

• Bally Casino 
• Bet365 Casino
• BetRivers Casino 
• Golden Nugget Casino 
• Hard Rock Casino 
• PlayStar Casino 
• Unibet Casino 
• WynnBET Casino 

Even if you live in a state without real money online casinos, you can still play online slots on social and sweepstakes sites. These sites invite players in nearly every U.S. state to play slots and other games using virtual currencies and, in some cases, offer ways to redeem winnings for cash prizes.

Top social and sweepstakes sites with slots include:

• Pulsz 
• Chumba Casino
• LuckyLand Slots
• Funzpoints
• WOW Vegas

These social and sweepstakes sites primarily (often exclusively) feature slots created in-house, which means the slots are entirely unique to the site.
