Practical tips for choosing trustworthy slot sites

Check the US gaming license

All our US slots sites have a proper gaming license. When you play on licensed US casino sites, you can be certain that you're dealing with a legal and appropriate online casino.

Finding the following elements on a slot website should tell you that the casino is properly licensed:

The first place to look is the footer on the casino's homepage. If you can't locate the licensing info there, it might be displayed on the "About us" page instead.

It's also important to know which states have legalized online casinos because the legal status of gambling is different between the states. At the moment, these states are:

EXAMPLE: An online casino wants to operate in New Jersey. Therefore, it needs to be granted a gambling license from the New Jersey Division of Gaming Enforcement.

Look into the slot game providers

There are plenty of slot providers out there and the selection varies from one slot site to another. Some lesser-known companies may hold some hidden gems. However, not finding any of the household names on the site should be a red flag.

Among the most widely available slot makers are:

However, there are many fresh game suppliers producing quality slots on a regular basis.

Read reviews of the US slots sites

Our slot site listings are created by our team, in collaboration with the slot sites. The sites are also rated by the Bojoko community and our casino experts.

The community ratings consist of a numeric rating with a comment summarising the players' experience.

The reviews by casino experts are more detailed. After thorough testing, including a real money deposit and withdrawal, they carefully cover all aspects of the slot site in question.

By checking out our online casino reviews, you'll know what players just like you think about these slot sites. The ratings made by users help you pick the best online slots sites to play slots and win. You can also have your say and write your own reviews to contribute!

Try slot sites with a bonus

Casino bonuses can be found in practically all casinos and US slot sites are no exception.

There are plenty of options to choose from. They're targeted at slightly different player types:

Play with ease on top mobile slot sites

Mobile slot sites are 100% optimized for all smart devices, i.e. mobile phones and tablets. Play your favorite games whenever you like, wherever you like.

Good mobile slot sites have a wide selection of games and top-notch usability. They offer payment methods specially tailored for smartphones. The support team will help you with all matters related to mobile gaming.

Take your pick from the list found on this page and spin the reels with your smartphone!

Slot sites and responsible gaming

Gambling is always risky and the more you play, the likelier it is that you will lose. Even the best slot websites are there to make money for their operators and not give it away.

The statistical outcome of every casino game is negative for the player. This means that with every spin, you come closer to eventually losing your money. It is important to understand the mathematics of gambling and to keep control.

Online gambling is a form of entertainment, and it should be treated as such. These games and sites are not there to fix any kind of financial issues. Play responsibly and stay in control.


Although it's hard to name a single best slot site, here are some great options to start with:

As long as the site is licensed in the US, it can be considered trustworthy. On Bojoko, we only show US-licensed online slot sites.

Being licensed by any of the official regulatory bodies in the US, like Delaware Gaming Enforcement or Pennsylvania Gaming Control Board, means following very strict licensing conditions. Breaking them often results in fines and/or losing the gambling license. That's why licensed slot sites have a strong incentive to play fair and keep their license.

Although there are some sites focused 100% on slots, most also offer a wider range of games. These include:

  • Jackpot games
  • Bingo
  • Poker
  • Blackjack
  • Roulette
  • Scratch cards
  • Lottery
  • + many more

Yes. You can either:

  • Test the slots in free mode to learn how they work, or
  • Get a no deposit bonus and have a chance to win real money

In the US, some online casinos do limit the free slot demos only for registered users. But, on Unibet you only need to confirm that you're over 21 to play the demo versions for free.

Offering no deposit bonuses is one of the main channels for slot sites to acquire new players. A free sign-up bonus gives you the possibility to win money without depositing your own cash.

On the No deposit bonuses page, you can see all US casinos offering no deposit free spins and other free sign-up bonuses.

Slot sites usually offer the registration bonus as no deposit free spins. Sometimes you can also get free bonus money without making a deposit.

Free spins are given to a specific online slot, whereas free bonus cash can be used for practically any game. Only the highest RTP slots, table games, and live dealer casino games are usually excluded from bonus play.

Read the terms and conditions of the no deposit bonuses to avoid any hidden catches. Make sure wagering requirements, withdrawal caps, maximum bets, and restricted games don't come to you as a surprise.
