How we ranked the best Ontario slots sites

A rich game library means players always have something new and exciting to try. The best Ontario online casinos offer a wide range of slot games, from classic three-reel slots to modern multi-way video slots.

It’s also important to check who supplies these games. It’s a good sign when an online casino works with well-known software providers. These companies only partner with regulated online casinos in Ontario, and their games deliver sharp graphics, engaging themes, and fair play.

Other casino games

While players might be looking for the best online casinos in Ontario for slots, it never hurts to have a few extra options. Top casino sites always offer a wide range of games, including table games like blackjack, roulette, baccarat, and poker.

It’s even better when the online casino offers live dealer games, as well as Ontario lottery games, video poker, scratch cards, keno, and bingo.

This variety ensures Ontarians will always have something new and exciting to try.

Ease of use

Top online gambling sites should be easy to navigate, which helps players quickly find their favourite games. All Ontario online casinos in this guide work well on mobile devices, but we also checked how responsive their websites and casino apps are.

Having reliable customer support is really important, too. This review guide thoroughly tested sites offering 24/7 assistance via live chat, email, or phone, ensuring help is always available, day or night.

Payment options

Regulated Ontario online casinos support fast and secure ways to deposit and withdraw money.

The best slots sites offer multiple online banking options like credit/debit cards, e-wallets, bank transfers, and prepaid cards. So, players in Canada will be able to find popular choices like Visa, Mastercard, Interac, iDebit, and MuchBetter.

Book of Dead (Play’n GO): RTP – 96.21%

Big Bass Bonanza (Pragmatic Play): RTP – 96.71%

Types of online slot machines to play in Ontario

The best Ontario online slots casinos offer several different types of slot machines, each with its own unique features, advantages, and drawbacks.

Take a look at the options available at the leading online gambling sites and see what makes each type special.

Three-reel slots

When players think of traditional slot machines from back in the day, they think of three-reel slots. These casino games have three vertical spinning reels, each with a set of symbols. To form a winning combination, players need to match these symbols across a single payline.

Classic three-reel slots are easy to play, making them perfect for online gaming beginners. They can also awaken a sense of nostalgia, especially among experienced gamblers, and often offer higher RTPs.

However, they can be a bit outdated and overly simplistic, so players won’t find many extras or features like in modern slots with more paylines.

Five-reel slots

Here, players can expect five vertical spinning reels instead of three. This setup allows for more symbols and combinations, effectively increasing the number of paylines and ways to win.

Typically, five-reel slots feature sharper graphics, better sounds, and immersive themes with extra gameplay features. As a result, they keep players engaged longer and coming back for more.

On the downside, these slots are often more complex, especially for casino newbies. Contrary to popular belief, five-reel slots usually offer lower payout rates than three-reel options.

Multi-payline and multi-reel slots

These slots have more than the usual three or five reels and offer multiple paylines, which increase a player’s chances of winning.

Some of these games let players choose how many paylines they want to activate before spinning the reels — sometimes up to 20, 30, or even more. Others have several fixed paylines, which can drive the minimum bet up slightly higher.

While multi-payline and multi-reel slots are more engaging and offer various betting options, they can become costly, especially when a user activates all the paylines. Beginners also find them more challenging to understand.

Video slots

Video slots are online versions of slot machines found in land-based casinos. They can have three, five, or more reels and multiple paylines. All of these slots contain some type of reel or grid layout, paylines, and winning combinations.

However, they can feature many different themes and extras like bonus spins, multipliers, and interactive mini-games.

Video slots offer many advantages compared to other forms of gambling, such as table games, sports betting, and live casino games. The wins are unpredictable due to the use of random number generators (RNGs), making them easy to play, regardless of experience.

Plus, they are incredibly entertaining, with bright lights and flashy visuals.

The only drawback is that video slots may sometimes offer lower RTP than simpler slots.

3D slots

3D slots take video slots to the next level with three-dimensional graphics and captivating gameplay. Unlike 2D slots, which focus mainly on user experience, 3D slots look and feel much better.

These games often have unique themes, engaging storylines, and interesting characters, making for a more immersive experience.

However, the stunning graphics and animations are heavier on devices, so players will need a more powerful one for the best performance.

However, since 3D slots are still fairly new, Canadian casino players can expect leading providers to keep improving their features and performance. After all, they are the future of slot games.

Branded slots

Branded slots are a subcategory of video slots. These games are available at most online casinos in Ontario and are usually based on popular movies, TV shows, music, and other media.

Players love them because they feature familiar characters and themes, often with unique bonus features. For example, there’s a slot game based on the TV show Game of Thrones, featuring characters from the series and special bonus rounds inspired by key plot points.

These slots are great because they have engaging themes and high-quality graphics and sounds. However, they can be more expensive to play and sometimes offer lower RTPs due to licensing fees.

How online slots games work

Online slots are one of the most popular casino games, offering exciting gameplay, stunning visuals, and the potential for big wins. Here’s a breakdown of how they work:

Coin value: The coin value refers to the amount of money you bet per coin. It’s adjustable in most online slots, allowing players to control how much they’re wagering. Typically, the coin value can range from a few cents to several dollars, depending on the game and casino platform.

Bet level: Bet level, also known as the “stake level” or “bet per line,” refers to the number of coins a player wagers per payline. The higher the bet level, the higher the potential payouts, but it also increases the overall bet amount for each spin.

Paylines: Paylines are the patterns that symbols must align in for a player to win. Traditional slots usually have 3 paylines, but modern video slots can feature hundreds of paylines, offering more opportunities for wins. Players can adjust how many paylines they want to activate, depending on the game.

Bonus features: Online slots often come with various bonus features designed to enhance the gameplay experience. Wild symbols substitute for other symbols to help form winning combinations, while scatter symbols can trigger free spins or bonus rounds.

Cluster pays: Cluster Pays is a unique feature where instead of paylines, groups of symbols that form a cluster of a specific number (usually 4 or more) trigger a win. The more symbols in the cluster, the bigger the payout. This mechanism adds a fresh twist to the traditional slot format.

Tips for playing online slots in Ontario for real money

Online casino gambling is super fun and exciting, and it’s even better when players have some insider knowledge. Here are a few tips for playing slots at Ontario gambling sites:

Read the paytable first: Here, users can learn how to play the game and see a list of all payouts, including regular symbols and bonus icons. It helps players understand the slot and decide whether they prefer a game with more frequent, smaller wins or less frequent, higher payouts.
Always start with the demo version: Most online gambling sites offer their games in demo mode. New players playing the game for the first time should start there. Free play will help one understand the game mechanics, features, and bonuses without any financial risk. After learning its ins and outs, players can start playing for real money.
Check the RTP (Return to Player): The RTP percentage shows how much of the money wagered on a slot is paid back to players over time. A higher RTP means better chances of winning in the long run. The best Ontario online casinos usually offer slots with RTPs above 96%.
Spread out those bets: Learning how to manage a casino bankroll is crucial. Betting too much can deplete funds quickly, while betting too little minimizes potential winnings. A good strategy is to wager around 1 per cent of the bankroll on each spin, adjusting stakes based on performance.
Remember, all slots are random: Online slots use Random Number Generators (RNGs), meaning each spin is independent. There’s no such thing as a hot or cold streak, so don’t get carried away thinking a big win is just around the corner.
