We looked for online slots sites that offer users amazing game variety, high RTP slots, generous bonuses for new and existing players, and much more. In the end, we found Ignition to be the best overall option – but there are many others worth your time and attention!

So, without further ado, let’s dive right in.

Best Slots Sites

1. Ignition Casino – Best Online Slots Site Overall

Ignition Casino


  • Over 120 casino games
  • Top-notch poker room
  • Up to $3,000 welcome package
  • Amazing referral program


  • Limited selection of mobile games

While Ignition Casino might be primarily known for its world-class poker room, the site also has an excellent array of slots and table games. Not only that, but they’re not shy about handing out bonuses.

Game Selection: 4.9/5

Ignition Casino’s games library is thin, but it compensates thanks to its diversity of game categories to play. There are 120 games, slot machines dominating the list with 56 titles from more than ten providers, and you can play colorful 5-reel slots in different paylines with exciting bonuses on its slots section.

Also, there’s a decent selection of progressive titles if you want to play for bigger jackpots. However, they’re mixed in with the regular slots, making it hard to see all of them (and their jackpots) at a glance.

Its selection of table games also comes with friendly betting limits. Here, you can bet for as low as $1 or go all the way up to $10,000, so both low-limit players and high-rollers will find plenty of action.

Bonuses & Rewards: 4.85/5

There are separate bonuses for the casino and poker room, but they’re both the same. If you deposit with crypto, you’ll enjoy a 150% match up to $1,500 in both sections of the site for a cool $3,000 total.

Fiat currency players won’t get quite as much money, but they’re still eligible for a respectable 100% match up to $1,000 on both sides.

Crypto users are spoiled even further as the site runs a weekly 100% deposit match up to $1,000. Players who prefer credit cards also have a weekly bonus available – but theirs is capped at a measly $100.

Mobile Compatibility: 4.95/5

Much like other online casinos that we discussed, Ignition also offers users browser-based mobile gambling. You can simply visit the Ignition website using any of your mobile devices and play mobile slots.

Banking: 4.9/5

This operator offers a decent Cashier section that you can count on for reliable payments. It supports traditional payments like Visa, Mastercard, and AMEX and accepts four cryptocurrencies – BTC, BCH, ETH, and LTC.

The withdrawal options are limited, with only cryptocurrency, wire transfer, and check by courier available.

Overall: 4.9/5

Ignition might not be the first online casino to come to mind when talking about slots, as it is primarily known as a poker gambling site. However, after our research, we found that it can be an amazing choice for slot lovers, too.

2. Slots.lv – Best Slots Site for Progressive Jackpot Games

Slots.LV Casino

  • Up to $5,000 in welcome bonuses

With big-name software providers like Microgaming and Netent filling out its portfolio, you’re sure to find many of the top titles on the market today here, including “Mythic Wolf,” “10 Times Vegas,” and more.

The table game selection values quality over quantity as well, featuring multiple types of roulette, blackjack, and baccarat. Beyond that, you’ll find multiple jackpot tables in their Caribbean hold ’em section.

Your chance at a big score doesn’t stop there, as there are nearly 40 progressive jackpot slots here, with pools that often reach six figures or more.

Bonuses & Rewards: 4.8/5

If there’s one section that Slots.lv truly impresses, it’s the bonuses and promotions. Players who deposit using fiat currency can enjoy a 200% bonus match on their first deposit (up to $1,000), followed by a similar match (up to $500) on their subsequent eight deposits.

In case math isn’t your strong suit, that adds up to $5,000 in bonus cash.

Bitcoin users have it even better, as they can enjoy a 300% deposit match for a total of $7,500 in bonuses. On top of that, if you refer a friend and they use BTC, you’ll get $25 extra.

Mobile Compatibility: 4.8/5

Mobile gameplay is possible through iOS and Android devices. The website works well on mobile devices, but we noticed that there are some games missing on the mobile version.

Banking: 4.8/5

Their banking options cover traditional methods such as Visa, Mastercard, and AMEX, but as you might expect, cryptocurrencies are the star of the show.

There’s also support for Bitcoin, BCH, Ethereum, USDT, and Litecoin, thus allowing you to enjoy fast, almost free, and private transactions.

Your balance is also helpfully divided up between your available funds and however much bonus money you have left to earn.

Overall: 4.8/5

Slots.lv offers a fun, vibrant, and relaxing gambling environment. There are game teasers on the homepage that are playable in the free demo, and there are game and crypto guides, too.

All in all, it’s a great site for beginners, but there’s plenty here to keep the experienced slot jockey coming back as well.
