Casino Days
Casino Days delivers an impressive slots experience with thousands of games from Pragmatic Play, Play’n GO, Push Gaming, and other leading developers. We’re big fans of the branded exclusive games it has, like Book of Casino Days and Casino Days: Starburst.
You’ll have full access to Pragmatic Play’s Drops & Wins tournaments, adding a competitive element that you won’t find everywhere. Read our full Casino Days Ontario review for more.
Favorite online slots: Gates of Olympus, Razor Returns, Book of Casino Days
Slots Magic
This isn’t a typo: Slots Magic has nearly 6,000 slots to choose from. It goes without saying that it’s the largest volume of any operator on this list, and that you’ll have no problem finding something you like. One feature we love on the website and app is a Hot & Cold tab, which shows specific online slots that have paid out lately and those that haven’t.
If nothing else, it helps players find fun and engaging slots. There are a ton of progressive jackpot slots, so the chance to win big here exists, too. See the Slots Magic Ontario review for the full breakdown.
Favorite online slots: Big Bass Bonanza 1000, Book of Dead, Barbarossa DoubleMax
PlayOJO
With hundreds and sometimes thousands of online slots to choose from, it can be difficult to know where to begin. That’s why we love how simple PlayOJO makes it to find new slots, with dedicated sections for trending releases, popular games, Megaways, and exclusives. The “Popular Near You” section also gives you an inside look at what other players are frequenting. It makes for a great user experience.
Favorite online slots: Book of Dead, Big Bass Splash, Buffalo King Megaways
BetVictor
Users will have access to more than 3,000 games when they play at BetVictor, which has a bundle of branded exclusive titles that often have recurring promotions attached to them. It also has a great filter function that makes navigating to your favorite online slots a simple task.
Favorite online slots: Amazing Link Zeus, The Racaroon S’mores, The Goonies: Hey You Guys!
Sports Interaction
Sports Interaction is typically associated with its online sportsbook, but it has a great array of online slots, too. We’re particularly interested in the 70+ progressive jackpots that are available to players looking to win big. Players can also toggle to the “Top 12 Games Played” section that shows the most popular games at any given time.
Favorite online slots: Bison Fury The Stampede, Scorching Fruits 40, Cleopatra
Party Casino
Classic online slots are great, but it’s also really fun to check out the newest titles. Party Casino knows that, too, promoting 30 new titles hitting the platform each month. You can also filter by the most-played slots at any given time, getting in on the action that others are checking out. It also features more than 80 exclusive titles, so you’ll be getting access to games you won’t find elsewhere. Read our full Party Casino Ontario review for the games, banking and app details.
Favorite online slots: Sweet Bonanza Super Scatter, Cash Eruption, The Flintstones Bedrock Riches
How We Rank the Best Online Casino Slots
The best features of the top online casino slots are subjective, since different users want different things. Still, there are some features that all the options on our list seem to have. Pick what’s important to you, but this is what we feel is critical when choosing your favorite online slots to play.
- Number of online slots: A large quantity of online slots is usually a good sign that an online casino is invested in its product. It also gives players more options to choose from, which is helpful given the different game styles and rules among the thousands. Variety is always a good thing.
- RTP and betting limits: RTP stands for return-to-player percentage, which is the average return players can expect. It’s not a guarantee, since those simulations are run thousands of times, but generally a higher RTP is better. Betting limits won’t come into play for most players, but it’s still nice to have high limits for those looking to bet big.
- Welcome offers and slot promotions: Rules prohibit us from discussing Ontario welcome offers, but it’s good to find an online casino that provides a good one for new players. These operators often will have promotions around certain slots, or tournaments and leaderboards where players can earn more as they play and win more.
- Mobile experience: The online casinos we’ve chosen all have mobile apps for Apple and Android devices, and the software developers who created the games all make the slots mobile-compatible. The mobile experience matters more than players anticipate, but it’ll pay off in the long run.
Final Verdict
Ontario touts some of the industry’s leading online casino slots. The top online casinos have slots from the best software developers, and they’re constantly churning out new games with unique features, animations, and gameplay.

Customer support at the leading Ontario online casinos also do a wonderful job of helping players who believe they have a problem and pointing them to resources (both internal and external) for assistance.
