Top 8 Highest RTP Slots at Canadian Online Casinos December 2025
How do High RTP Slots Work?
You might have heard of high RTP slot games - you’ll often see them recommended for the best chance to win real money. But do you understand exactly what a high RTP game is? Before we get into our full guide to the highest RTP slots, let’s explain things in simple terms.
So, what is RTP in online slots? Well, RTP stands for Return to Player, so the RTP percentage is the amount of money staked on a game that should theoretically return to players over a long period of time. For example, if a slot has a 96% RTP, $96 out of every $100 should pay out. What’s left over is the “house edge”, which is what the casino keeps.
In general, you should always look for the highest RTP slots, as this gives you a better chance of winning over time. But it’s also important to remember that it isn’t a guarantee of a win during a single gaming session (or indeed, ever). RTP is calculated over millions of spins.
While you’ll have a slightly better chance of getting lucky on a game with a 97% RTP than on one with a 94% RTP, the games all still use Random Number Generator technology. That means the combinations of symbols that appear every time you spin are randomized by sophisticated algorithms.
Best High RTP Slots Games
The industry standard for slot game RTP is around 96%, so most games fall between about 96% and 96.5%. We’d consider anything higher than this to be in the category of best RTP slot games.
There are some games that really break the mold, with payout percentages of 98% and upwards, but these are rare. They’re not available at all online casinos, but if you spot one, we’d highly recommend giving it a go.
Just like other slots, the highest RTP slots come with special features like bonus rounds and multipliers. Expect to see unique themes like adventures, fantasy and money. We’ll list a few of our favorites here, so you can choose one you like the look of.
1. Book of 99 - Relax Gaming
There are very few games with a 99% payout rate. In fact, this might just be the highest RTP slot we’ve ever seen (along with Mega Joker). It’s available at some of the best Canadian gambling sites, like RealSpin casino.
Book of 99 is set in a mystical land where monsters and magic reign free. You’ll be aiming to match symbols on one of 10 paylines to land yourself a win. The wild symbol takes the form of a book, and it can substitute for other symbols, plus trigger the free spins round. You’ll also collect wilds as you play, to fill up the special meter and get more free spins.
2. Mega Joker - NetEnt
NetEnt’s Mega Joker has the look and feel of a classic slot, with all the fun of a modern game. This is one of the best high RTP slots in the world, with the payout percentage sitting at 99%.
Mega Joker is a simple three-reel slot, but there’s one outstanding feature here: the game has a progressive jackpot! That’s really unusual for high RTP slots. The jackpot prize can be triggered randomly, so you never know when you might walk away with this impressive payout.
Mega Joker is available at RealSpin casino and other sites, although it’s not quite as common as some newer titles at NetEnt casinos.
3. 1429 Uncharted Seas - ThunderKick
It’s time to venture out into uncharted seas! This Thunderkick game has a super high RTP of 98.6%, and you can play at a few top Canadian online gambling sites, like Casino Days.
1429 Uncharted Seas is set on a grid that looks like an ancient map. The visuals here are totally different to what you might have seen on most other online slots. There are 25 paylines active every time you play, and the low volatility means you’re likely to land frequent small wins.
Bonus symbols get you into the free spins round, with up to 50 free spins. The game also comes with expanding wild symbols, which can fill up the whole reel, giving you extra chances to win.
4. Marching Legions- Relax Gaming

Marching Legions is set in ancient Rome, but the graphics look a little like a retro computer game. The game comes with 243 ways to win, by matching symbols on adjacent reels from left to right.
Land stacks of the legionnaires symbols to trigger the respins feature or collect the legionnaires to get into the free spins round. If you’re impatient, you can even buy your way into the bonus round!

Relax Gaming’s Money Cart is a Wild West adventure, where you’ll have to track down outlaws to reap the rewards. The game has a high RTP of 98% and amazing HD graphics, making it a stunning choice.
Gameplay works a bit differently to most slots. The aim here is to collect symbols on the reels to open up the respins feature. Here, the grid can increase in size, giving you more chances to bag a win. Look out for the very special Payer and Collector symbols, which can add extra money to your winnings.
If cash, crime sprees and thrills are right up your alley, you can try out Money Cart at Northstar Bets casino.

Best Paying RTP Slots Welcome bonus
If you’re thinking about signing up at a new online casino, you’re definitely going to want to check out the welcome bonus. Most sites offer a deposit match, some free spins or a certain percentage of your losses back. Worthwhile Canadian online casinos also have regular promos whenever you come back. These can be as frequent as every single day!
The only bad news is that sometimes very high RTP games can be excluded from bonus play, or from contributing towards wagering requirements. So it’s important to check the T&Cs before you try to play. Even if you can’t play your favourite high RTP games, we’d still highly recommend claiming the welcome bonus anyway. That way you might just get lucky enough to bag some real cash.
Free Spins
Free spins are usually handed out on mid-range RTP games like Starburst, Book of Dead or Sweet Bonanza, which all come in at around 96%. Some online casinos are even generous enough to give you the spins on a top slot game before you need to deposit, so you can test out the game for free.
Deposit Match
A deposit match is a great way to boost your balance by claiming a percentage of your first deposit as bonus money. It’s usually 100% or 200% and can go up to thousands of dollars at some casinos. You might be able to use your deposit match bonus money to play high RTP slots, but be sure to check if there are any exclusions.
Losses Back
Loss back promos tend to come with fewer exclusions than other types of online casino bonuses, so they’re a great option if you want to play high RTP slot games. If you’re unlucky during the promo period, you’ll be able to claim a percentage of your net losses (anywhere between 10% and 100%) back, either in the form of real cash or a casino bonus.
What to Look For in the Best Slots With the Highest RTP?
Having a high Return to Player percentage doesn’t automatically make a new online slot game worth your time. There are a whole lot of other things you need to look at before you decide to play a slot for real money.
First, consider the theme. There are tons of different themes out there: everything from ancient Egypt, to animals, to classic slots with symbols like gems and bars. So find one that suits you.
Next, check out the actual gameplay mechanism. We’re big fans of games that use Megaways and Cluster Pays, as these features tend to make gameplay more exciting than the average slot.
And finally, take a peak at the special features. A lot of slots come with free spins rounds, multipliers, gamble features or even jackpot prizes. These special features give you extra chances to win and make for thrilling play.
It’s also a good idea to have a thorough look at a new online casino site before you sign up. Check if there’s a good welcome bonus, dive into the game variety and test the mobile experience.
Bonus Features and Bonus Rounds in High RTP slots
The best RTP slots tend to concentrate on the quality of the bonus features, rather than the quantity, but they still give you lots of chances to win.
Free spins rounds are common, usually triggered by landing scatter symbols. Free spins games might come with expanding symbols, multipliers or the chance to re-trigger the round, giving you more free spins. These bonus rounds are often the best way to win generous amounts of money, and they tend to trigger relatively frequently.
While the highest RTP slots don’t tend to hold progressive jackpots, there are still chances for you to bag extra cash prizes. For example, games might come with smaller fixed jackpot prizes, or other features like money collect rounds, where special symbols award cash values.
If you’re particularly excited about a bonus feature and you can’t wait for it to trigger, some games have a built-in bonus buy feature, allowing you to pay your way into the bonus game. But this isn’t too common on high RTP slots.
Gambling Responsibly
As we’ve mentioned already, playing high RTP slot games doesn’t guarantee you’ll win, so there’s still a risk that you’ll lose some of your own real money. It’s super important that you gamble responsibly at all times and that you make use of a casino site’s built-in tools like deposit limits, loss limits, reality checks and time out to help you stay in control. You’ll also be able to self-exclude, to totally block access to your account if you feel the need.

Summary
It’s safe to say that high RTP slot games are a great option, as you’ll stand a slightly better chance at landing yourself a win. Some of these games even come with fun bonus features, to make gameplay that little bit more exciting. Just don’t expect to win every time you play - RTP is calculated over a really long period of time, so it’s never a guarantee.
Now that you know all about the highest RTP slots, it’s time to give them a try for yourself! Make sure you sign up at one of the safe and secure casinos that we’ve recommended on this page - and don’t forget to claim your welcome offer.
