#1 Immortal Romance Slot by Microgaming

There’s not a chance you haven’t heard about this slot game at least once. If you’re a slot fan, you should’ve played it hundreds of times.

One of the most popular slot games from Microgaming, aka Games Global, was launched back in 2011 and it is still a 10. With a return rate above the industry’s average and rather occasional big payouts than regular small wins, Immortal Romance is a top choice among Canadians. Especially because of the vampire theme and its amazing bonus rounds.

Bonus Rounds: This slots game is mostly known for its special features like Wild Desire (randomly triggered and able to turn five reels wild) and Chamber of Spins (triggered by landing 3 or more scatters and unlocking many free spin modes with unique bonuses like rolling reels, multipliers, or wild transformations).

The variety of bonuses received during the bonus rounds provides multiple possibilities to land a big win, let alone the high-quality graphics, amazing storyline, and 10/10 soundtrack.

#2 Dead or Alive II Slot by NetEnt

The 2019 slot game with quite a tracking record of big wins has an above-the-average RTP (Return to Player) and the potential for substantial payouts. And if you ever played this game, you know it gets you into the dangerous Wild West. Cowboy boots, wanted posters, and hats everywhere.

Bonus Rounds: This popular bonus round slot offers not one but three spin rounds. Old Saloon multiplies all wins by 2 with sticky wilds in place during the round. High Noon Saloon has a Max free spin mode with significant multipliers. Train Heist has a progressive multiplier that gets bigger with each wild, meaning additional free spins.

#3 Book of Dead Slot by Play’n Go

Another slot released a decade ago with a high return rate and less frequent but big prizes all due to its exclusive bonus rounds. The slot itself revolves around ancient Egypt’s adventures. Join Rich Wilde as he completes a new quest to find the mythical book.

Bonus Rounds: The only bonus you’ll find in the game is Free Spins, but these are more than enough. All you have to do to trigger this bonus is land 3 or more Book of Dead symbols and receive 10 free spins. That’s not all – during this bonus, a randomly selected expanding symbol covers entire reels. Just imagine the winning potential.

#4 Big Bass Bonanza Slot by Pragmatic Play

The further we go, the newer the slots are.

This one was launched in 2020 by Pragmatic Play, and it has been a phenomenon since then. Guess why? Bonus rounds!

Big Bass Bonanza has a return rate above the market average and a medium to high volatility, which, compared to others so far, means regular small wins and random big payouts. And as you might’ve guessed by the title, it is fishing-themed with plenty of fishing rods, various fish, and tackle boxes in an underwater space and an overall relaxing mode.

Bonus Rounds: This slot has two unique features. Free Spins are triggered by landing scatters and can award up to 20 free spins. That’s when the fisherman will collect from fish money symbols. The second feature is Multipliers – up to 10x during the fish money symbol collecting.

Immerse yourself in the calming vibe of this relaxing slot and its impressive potential for amazing wins at Betandplay.

#5 Gonzo’s Quest Slot By NetEnt

Back to the good old days, when this slot was released, in 2011.

With a slightly lower return rate but medium to high volatility, you can expect occasional big wins in this slot with frequent small wins. But the theme in this NetEnt-powered slot compensates for everything – an adventurous game following Gonzo in his attempt to find the city of gold. The rich graphics packed with action are amazing.

Bonus Rounds: It all begins with the Avalanche Feature instead of traditional spinning reels, meaning that new symbols fall into place when landing winning combinations. So get ready for multiple wins from the same spin. Think this is all? Not at all – each consecutive avalanche means an increased multiplier. The other feature you’ll like is Free Fall, which awards 10 free spins during which the avalanche multipliers get bigger, up to 15 times.

Now you get why I listed this game as well. If you’re eager to play it, this is where you can do this: SmokAce Casino, and Kingmaker Casino.

#6 Divine Fortune Slot by NetEnt

Launched in 2017, this phenomenon has reached unprecedented levels of popularity in Canada. Is it because of the bonus rounds? Let’s see!

Return rate – above the average. Volatility – medium, meaning frequent smaller wins and random bid drops. Theme – ancient Greek mythology with stunning architectural scenery. So far, so good. Let’s explore the bonus rounds!

Bonus Rounds: This slot game has the most bonus features on the list. Falling Wilds Re-Spins – wilds shifting down one position and awarding re-spins till disappearing. Wild on Wild – a wild landing beyond a Falling Wild covers the entire reel. Free Spins – triggered by 3 or more scatters and rewarding players with 12 free spins. And my favourite – Jackpot Bonus Game – triggered by collecting bonus symbols and awarding the chance to win up to 3 progressive jackpots.

How to Increase Your Winnings at Bonus Round Slots

A tiny bonus from me at the end of the article. Get better chances at online slots with bonus rounds.

Choose games with high return rates and decide between low volatility (frequent yet small wins) or high volatility (occasional but big payouts) based on your gaming style.

Select games with lucrative bonuses such as free spins, progressive jackpots, or multipliers.

Adjust your bet to maximize bonuses (some bonuses provide higher rewards for higher stakes) but don’t forget to stay within limits.

Besides bonus features in the game, use casino bonuses and promotions to extend your playtime and get even higher chances of landing a big win.

Play in demo mode first to understand the game mechanics and paytable.

Don’t chase losses and take regular breaks between sessions.

Play at regulated online slots sites only, such as the ones I recommended.
