1. 

   Starburst - Most Popular NetEnt Slot

   Possibly the most popular NetEnt slot, Starburst is a fairly simple game with a lot of potential. The 5x3 grid hides classic symbols like fruits and sevens, all within a futuristic space theme. Starburst's main feature is the Expanding Wild, which can appear on reels 2, 3, and 4, covering the reel and substituting for all other symbols. The game pays both ways, offers a top payout of 500x your bet, and has a total RTP of 96.09%. You can play Starburst at Knightslots or Stardust Casino.

2. 

   Sweet Bonanza - Best For Huge Win Multipliers

   For all the players with a sweet tooth, Pragmatic Play created Sweet Bonanza, generally regarded as the most fun slot to play. The 6x5 grid is filled with various candies, including the Lollipop symbols, which start the free spins. During the free spins round, multipliers up to 100x show up on the grid, increasing wins up to 21,100x your base bet. An RTP of 96.51% and a high volatility make Sweet Bonanza a game with great potential, but also a lot of variance. Try Sweet Bonanza at Ontario casinos like Neo.bet and DraftKings.

3. 

   Mega Moolah - The Biggest Progressive Jackpot Worldwide

   Developed by Games Global (Microgaming), Mega Moolah is the world's biggest progressive jackpot slot. The basic version of the game features a safari theme, although other versions are available for play as well. The bets in Mega Moolah are capped at $6.25, but the jackpot can be won with lower bets as well. The game's top feature is the progressive jackpot, which can be worth millions of dollars, as it accumulates over time at dozens of casinos. Because of the jackpot, Mega Moolah has a relatively low RTP rate of 88.12%, but also a low volatility and many base game hits. You can play it at Caesars or PartyCasino if you want to go for the jackpot.

4. 

   Book of Dead - Popular For Expanding Symbols

   One of the most popular slots coming from the Play 'n GO studio, Book of Dead is a game that's been around since 2016, and it's quickly become one of the best slots in Ontario casinos and for good reason. The game is loaded with symbols from ancient Egypt, the Book of Dead being the most lucrative. Three Books triggers 10 free spins with the Expanding Mystery Symbol feature. Wins as high as 5,000x are possible, with the overall RTP set at 94.25%. Give Book of Dead a spin or two at Caesars Casino Ontario.

5. 

   Gates of Olympus - Big Base Game & Bonus Wins

   If Egyptian mythology isn't your thing, perhaps Greek is. Gates of Olympus from Pragmatic Play is all about Zeus and his dominion on Mount Olympus. The 6x5 grid hides a variety of symbols, including the Zeus scatters, which trigger free spins. Random multipliers add up across the 15 free spins, and make wins of up to 5,000x possible in any bonus round. Gates of Olympus comes with very high volatility, but also a respectable RTP of 95.51%. You can try the game at 888 Casino or BetMGM Ontario.

6. 

   Cash Eruption - Jumbo Symbols For Jumbo Wins

   Created by IGT, Cash Eruption is another exciting slot featured at Ontario casinos like PlayOJO and SlotsMagic. The game features a traditional 5x3 grid, 20 paylines, and a range of bonus features like Expanding Wilds, Jumbo Symbols, Reel Links, and more. An RTP of 96% and max wins of up to 1,000x make Cash Eruption one of the best slots for Ontario players.

7. 

   Buffalo King Megaways - Over 200,000 Paylines

   The Megaways mechanic, first invented by Big Time Gaming, has become the staple for many game providers over the last few years. Buffalo King Megaways by Pragmatic Play is one of the most popular Megaways slots, featuring up to 200,704 paylines and max wins of 5,000x. Tumbling Reels, Wild Multipliers, and Free Spins make Buffalo King Megaways an exciting game where every spin can bring a big win. Try it at top Ontario casinos like PokerStars or BetMGM.

8. 

   Mega Joker - 99% RTP & Big Progressive Jackpot

   A progressive jackpot slot by NetEnt, Mega Joker is one of the most lucrative slot games around. It has a classic fruit machine design, featuring traditional symbols and a simple 3x3 setup with just five paylines. Despite that, Mega Joker offers plenty of opportunities to win big, with the Supermeter feature adding an extra path to big wins. The valuable progressive jackpot and massive 99% RTP rate, make it one of the best slots at Ontario casinos in terms of payouts. You can try Mega Joker at DraftKings.

9. 

   Jackpot 6000 - High Win Rate & Reduced Volatility

   Another NetEnt game with the Supermeter mode, Jackpot 6000 is a fruity slot with a 3x3 grid and five paylines that also carries a high 98.9% RTP. The Joker wild symbols offer wins of up to 6,000x. Unlike Mega Joker, Jackpot 6000 doesn't have a progressive jackpot, which makes base game wins more common and much bigger on average. You can play it at casinos like LeoVegas and 888.

10. 

    Bonanza Megaways - The Grandfather Of Megaways Slots

    One of the oldest Megaways slots developed by Big Time Gaming, Bonanza Megaways is a fun game with a mining theme, where uncommon gems can pay up to 26,000x. The free spins feature with unlimited multipliers makes every spin of Bonanza's reels just as exciting, as the game's 117,649 paylines hide massive wins. Try it for yourself at PlayOJO or Party Casino.

Types of Real Money Slots in Ontario - 3 Main Categories to Choose From

The best online slots to play in Ontario can be broken down into a few basic categories. Here is a look at the most popular types.

• Three Reels (Classic): The simplest to play are classic 3 reel variants and as you've probably guessed, they have 3 reels that are usually filled with traditional symbols like bars and sevens, and often come without any extra gameplay features.
• Multi Payline: More common these days, multi-payline slots feature anywhere from five to thousands of paylines. These games give you more chances to combine symbols on each spin, and more opportunities to hit those big wins.
• 5 Reel (Video): Video slots are modern games featuring advanced graphics, animations, and sounds, as well as bonus rounds and gameplay features that make them more similar to video games. Most of the best slots in Ontario fall in this category.

Playing Online Slots At Ontario Casino Sites - Best Tips From Our Experts

If you are ready to play the best slots Ontario has to offer, you may as well do it right. While these games don't require too much strategy, there are some things you can do to give yourself a better chance at coming out in profit. Below are the three tips every player should follow.

• Opt For High RTP: The RTP affects your long-term win rate. Games like Jackpot 6000 and Mega Joker have an RTP rate of 99%, which means the house only wins 1% of all bets in the long run. Mathematically speaking, this gives you a better chance to get lucky and win each time you play.
• Be Careful With Jackpots: Progressive jackpots like Mega Moolah may have a huge max win and the potential to change your life, but they also come with very low RTP rates. Mega Moolah's RPT of 88% makes it one of the lowest paying slots in the base game. Play these games for a limited time if chasing the jackpot, but be careful about investing too much into them.
• Adjust Your Bankroll Per Volatility: High volatility slots require a big bankroll to play. Slots like Gates of Olympus or Bonanza Megaways only pay big in the bonus rounds, which take time to trigger. Make sure to play these slots with a sizable bankroll and be prepared for major downswings in high volatility games.

Online Slots On Your Mobile - Apps & Fully Responsive Websites Are Common In Ontario

Licensed Ontario casinos allow players to enjoy their favorite slot games on the go. While casinos like Zodiac, PlayOJO, and Jackpot City feature downloadable iOS and Android apps, others will have websites that are fully adapted to mobile gameplay so you can play in your browser.

Whether you play in an app or an instant play casino version, expect to have full access to all the best slots, as these games are all compatible with all major mobile devices.

AGCO Game Rules & Information

All online casino games and sites in Ontario are supervised by the Alcohol and Gaming Commission of Ontario (AGCO). The regulator has a set of rules under which all slots and other games must operate. This includes information about the game being readily available to the player as well as the paytable and game rules. All game outcomes must be randomly generated by an RNG and should be checked.

The rules are strictly enforced too so you know when you play slots at iGO licensed casinos in Ontario, you can be assured that everything is being monitored.

Always Be Mindful When You Hit The Spin Button

Whenever you play slots or other casino games, caution and responsible gaming is always advised. Playing responsibly means only betting what you can afford to lose, never chasing your losses, and being aware of the amount of time you spend at casino sites. If you play beyond your means and find it difficult to stop, we recommend seeking counsel with sites like Connex Ontario or Responsible Gaming Council.
