2. Starburst – NetEnt

Launched way back in 2012, still remains as popular as ever among slot players around the world. In fact, it is arguably the most popular video slot ever. With its unique theme, simple yet effective gameplay, and massive wins, it is no surprise to see so many players flocking to spin those reels.

Starburst is a low-medium variance game with five reels, rows, and ten fixed paylines. You can bet anything from $0.10 to $200 per spin. The neon-colored symbols include bar signs, rubies, sapphires, and diamonds. The wild symbol is represented by the rainbow-colored starburst, and if it lands on the reels, it expands to cover the entire reel. This gives you an extra chance to win and triggers a re-spin. If another wild lands during the re-spin, you earn yourself another re-spin on a expanding wild.

The simple guitar riff that plays in the background perfectly complements the futuristic setting of this slot. Neat features such as autoplay and quick spin make the gameplay even smoother. Tried and tested on PC, tablet, and mobile, Starburst is undoubtedly one of the best online slots Canada has ever produced.

3. Bonanza – Big Time Gaming

is a six-reeled masterpiece by Big Time Gaming that breaks all the rules when it comes to traditional slot designs. With cascading reels, unconventional ways to win, and six reels of fun, this slot offers over 100,000 ways to win!

Set deep in a mining theme, the symbols include various gemstones, barrels of gunpowder, and stick of dynamite. The exploding rocks on either side of the reels represent the scratch card–like wins and fall onto the reels every time you land a win. A leprechaun stands next to the reels and cheers you on as you progress.

Bonanza has a very healthy RTP of 96% and its medium-volatility means big wins drop regularly. The minimum bet is just $0.20, while high rollers can bet as much as $20 per spin. The reaction metre to the left of the screen randomly adds spins to further boost your winning potential. The free spins bonus round is triggered when you land four “bonanza” Scatters, and it is here where the biggest and most consistent wins lie.

Bonanza might look chaotic at first due to all the symbols falling from above. However, it’s surprisingly easy to follow, and the entertaining theme and interactive characters are the perfect compliment to the excellent game mechanics. A truly innovative slot which is guaranteed to be in the collection of any reputable casino.

The symbols include scarab amulets, golden burial chambers, whips, and the infamous explorer Ricardo. A book acts as both the wild and the scatter symbol_. Before the start of each free spin feature, the book opens up and selects one symbol to expand and act as an expanding wild during the bonus round.

Although the free spins feature is where the magic happens, you will find other interesting features like expanded wilds, partial wins, and unique betting options which allow you to stop or skip spinning certain amounts.

Thor was the star of the show in the original , but in the sequel, Microgaming managed to fit the entire Norse pantheon of gods into one awesome slot. The Great Hall of Spins features four different game areas, each featuring a different character and a unique bonus game.

You begin your journey in Asgard, home of Thor, the God of thunder, where 10 free spins are transformed into WINNINGS with a 5x multiplier. Next up is the Valkyrie’s realm of Valhalla. Here, eighteen free spins provide stacked wilds on reels three, four, and five. Loki’s world of Chaos brings fifteen free sparks with a wild magic feature that turns icons randomly into wilds. Odin’s kingdom of Death awards twenty-five free spins with all prizes multiplied by a 2x multiplier, except the fifth free spin, which increases it to a 6x multiplier. Subsequent wins during the free spins feature in the Great Hall of Spins add complexity to the game and keep things interesting.

Thunderstruck II also features random “Wild Storm” feature, turning reels completely wild. The game boasts an impressive RTP of 96.65% and a medium to high variance. Betting starts at just $0.01 for one coin at its lowest value, with a maximum bet of fifty coins at its highest value, which equates to $125 per spin.

7. Gonzo’s Quest – NetEnt

Gonzo’s Quest is an industry classic that revolutionized online slots with its unique features such as avalanches, multipliers, and 3D graphics back in 2010. Set in South America during the quest for El Dorado, this five-reel masterpiece is full of animation, sound effects, and surprises.

The stone-faced totems serve as the reel symbols, and the Aztec carvings come to life when winning bet lines are hit. An explosive animation causes them to disappear, only to be replaced by new ones in a cascade. This avalanche feature continues as long as new win lines are created. Furthermore, each time this occurs, the win multiplier increases (up to a maximum of five).

Aside from the exceptional game design, the slot’s RTP of 95.97% and low variance provide consistently small yet frequent wins. A “free fall” bonus activates ten free spins whenever three buffer scatter symbols appear on reels one, two, and three. During these free falls, the multiplier grows faster and gives you a better chance of hitting the 2500x max bet multiplier jackpot of $2,500,000! A true masterpiece and one of the best online slots for Canadians.

Sea-themed symbols include buoyant drinks, fish fillets, tackle boxes, and life preservers. Special symbols include a treasure chest that serves as the scatter, and the game’s wild symbol—a happy angler holding a large fish. When one or more wilds shows up on the reels, it freezes in place and triggers a re-spin. If more wilds appear, the re-spins continue.

Land three or more scatters to activate ten free spins. The free games can be extremely rewarding as more wilds are added with each catch. Other cool features include the gamble bonus, which gives you the chance to double or quadruple your win by correctly guessing the color or suit of a card. Betting ranges from $0.10 to $10 per spin, making it a great option for low-stakes players. The slot carries an RTP rating of 96.12%.

9. Dead or Alive – NetEnt

Dead or Alive is a fan-favorite western-themed slot by NetEnt that has been around since 2009. Even though it lacks the advanced graphics and features found in newer releases, it still manages to provide hours of entertainment thanks to its nine paylines, five reels, and stunning 110,000 coins max bet multiplier.

Low-value symbols include marshals’ stars, ten through ace, while wanted posters, revolvers, cowboy boots, and the outlaws themselves serve as higher paying symbols. The “wanted” poster is the scatter symbol, and if you land at least twelve of them anywhere on the reels, you win free spins. All wins during the free spins round benefit from a 2x multiplier. The feature can be hard to land, but when it does, those wild multipliers can lead to huge rewards.

Dead or Alive has a high variance, so expect lengthy periods of small or no wins. Stakes can be adjusted as low as $0.09 per spin, but to qualify for the max bet multiplier of x2400, you’ll need to play at $12.50 per spin. The slot’s RTP is rated at 96.80%. Catch those wanted bandits and enjoy the thrill of the old west while playing one of the best penny slots on the market.

10. Twin Spin – NetEnt

rounds out our selection of the top ten online slots. This retro-style fruit machine has a classic Las Vegas vibe with a modern twist. Developed by NetEnt, Twin spark delivers an RTP of 96.60% and its medium volatility guarantees regular payouts.

The neon-themed symbols include cherries, lemons, kiwi, grapes, oranges, llamas, and royal flush poker values. The aim of the game is to get matching symbols along one of the twenty five win lines. Twin spin gets its name from its main feature, where adjacent reels land matched symbols at the start of each spin. The connected sets of reels can range from identical symbols on two reels, up to five linked reels with the same symbol.

Another cool feature is the upgrade function, which elevates symbols within the connected reels to match the highest valued symbol in view. Despite having no free spins, bonus games, or wild cards, the innovative linked-reel mechanism provides enough excitement to compensate for their absence. Available for mobile and desktop, Twin Spin is certainly worthy of its place as one of the best online slots.

How to Choose the Best Online Slot Machine?

When it comes down to choosing the best online slot machines, several key variables determine whether or not you have an enjoyable gaming experience. These include:

  • Game Design – You can tell a lot about how good a slot is from its visual design alone. How well thought out is the theme and do the moving parts and animations make sense. You don’t want things appearing and disappearing without logic or reason.
  • Features – Does the game have free spins, bonus rounds, multiplier bonuses, and other added extras. Do these features trigger often enough, or do you have to spin for hours on end to get anything back?
  • Return-to-Player Rate – AKA RTP. This ratio indicates how much the slot pays back to the player over a long period of time. A rate higher than 95% is considered good, although this number only shows long-term trends, and short-term results can vary dramatically.
  • Betting Limits – A good slot should offer flexible betting limits, starting low enough for players to enjoy a leisurely game at a , and high enough to offer big-bet VIPs the thrill they crave.
  • Platform Compatibility – We live in a mobile age, and therefore, the best online slots must be fully compatible with smartphones and tablets.

In addition to the above points, other factors like software provider, platform reliability, and licensing are also important. Always play at fully licensed and that use trusted, third-party certified games. Check for certificates from organizations such as eCOGRA, iTechLabs, and GLI, which test fairness, security, and safety.

3D Slots

are the latest iteration in the evolution of video slots. As the name suggests, these games feature superb 3D graphics that add depth and realism to the game and its characters. Titles such as At the Copa, Arlington Cup, and Lucky Leprechaun all use 3D graphics to enhance the user experience.

2D Slots

If 3D slots are too much for your computer to handle, you might prefer to try some of the excellent that use classic cartoon-style graphics. Games like Bar Bar Black Sheep, Cash Clams, and Chilly Heat are just three examples of the many quality two-dimensional slots you can play online.

Jackpot Slots / Progressive Jackpots

Online slots offer a wide range of jackpots that can payout anywhere from a few hundred dollars up to multi-million dollar figures. Most slots offer fixed jackpots that are proportional to your wager, meaning the larger bet you place, the bigger the prize. Multiline slots can offer larger fixed jackpots, as they have more paylines and therefore more ways to win.

Flat Jackpot Slots

A flat jackpot is predetermined by the developer and stays constant regardless of external factors. For example, if a slot has a top prize of 1,000 coins, it won’t change based on the size of your bet. Therefore, a $1 bet can win up to $1,000, whereas a $100 bet would only win $100,000.

Progressive Jackpot Slots

A progressive jackpot continually increases in size each time someone plays the slot but does not win the prize. When the jackpot is finally won, it resets to its base amount, which typically ranges from $10,000 to $50,000. A network progressive is linked across multiple casinos, providing much bigger and more lucrative jackpots. One example of a flat jackpot slot is Money Magic, while Mega Moolah is a perfect illustration of a progressive jackpot slot.

Buy-a-Feature / Buy-a-Bonus Slots

Buy-a-feature slots allow you to skip the monotonous base game and go straight for the bonus features by paying a certain multiple of your stake. Offering instant access to free spins, pick me rounds, wheel of fortune bonuses, and other special features, these slots are particularly appealing to high rollers and experienced slot players. Note that activation does not guarantee a prize.

Virtual Reality Slots

Virtual reality (VR) technology has opened the door for fully immersive 360-degree slot experiences. Donning an Oculus Rift headset, for example, transports you into a 3D environment where you can interact with the game in amazing detail. Top VR slots casinos like to offer generous match bonuses to encourage players to try out this revolutionary new technology.

Megaways Slots

Blueprint Gaming invented the Megaways engine, which Big Time Gaming later licensed. This mechanic randomizes the number of symbols on each reel, which in turn alters the number of ways to win on each spin. The concept takes all the best elements from other slot mechanics and enhances them, leading to huge wins and blockbuster hits. Popular titles include Buffalo Rising Megaways and Ted Megaways.

Cluster Wins / Cluster Pay Mechanics

Instead of paylines, cluster pay slots such as Tumbling Reels and Cascading Reels rely on groups of matching symbols to provide wins. Whenever a win occurs, the related symbols explode or tumble away, allowing new symbols to replace them from above. If the new combination creates another win, the process repeats itself, giving you free shots at hitting the jackpot.

MultiLine / Multiway Slots

Multiway slots such as Starburst offer multiple ways to win. Unlike traditional slots, which usually have fixed paylines that determine the cost per spin, multiline games count every possible combination of symbols across each reel, creating a vast array of ways to win.

For example, if you have reels with symbols, eight positions high, then the number of ways to win would be:

  • 1 symbol = 8
  • 2 symbols = 64
  • 3 symbols = 504
  • 4 symbols = 4032
  • 5 symbols = 3125
  • 6 symbols = 2592
  • 7 symbols = 2304
  • 7 symbols = 128

Therefore, Starburst has 1024 ways to win, which can increase with additional features that lock winning combinations in place while receiving a free re-spin.
