6 Best Slot Games With Bonus Rounds

#1. South Park: Reel Chaos by NetEnt

South Park: Reel Chaos by NetEnt - slots with bonus rounds

South Park: Reel Chaos is a normal 5-reel slot machine provided with all the eccentricity and unpredictability you’d expect from the South Park brand, similar to previous South Park video slots (e.g. South Park: Porkies and South Park: Video Slot Machine).

We suggest you keep your sound on while playing because it’s actually pretty funny. However, even without the sound, there’s plenty to keep you busy thanks to the four mini-features, one bonus round, and the amusing animation.

Additionally, there are certain interesting sub-features that are included in the game which are listed just below.

  • Stan’s Multiplying Re-Spin: This feature appears at random after a no-win spin; it’s wonderful since it keeps spinning until you win, so you know that if it appears, you’ve surely won something. Each re-spin awards a multiplier, so keep it spinning as long as possible.
  • Kenny’s Multiplier: Professor Chaos and Kenny battle after a win in the main game, which is unlocked at random. As Kenny wins, multipliers are added to the winning wager until Kenny is killed by Professor Chaos.
  • Cartman’s Stacked Wilds: Cartman pursues General Disarray around the reels, converting symbols into wilds and maybe producing a win, in yet another random activation during the main game.
  • Kyle’s Overlay Wilds: During the main game, the evil minions will try to take over the reels, but Kyle will shoot them down with his laser beam, causing 3 to 5 overlay wild symbols to appear on the reels.

The Bonus Round

The bonus round makes things all the more fun.

The bonus game is triggered by three bonus symbols occurring anywhere on reels 1, 3, and 5. Mintberry Crunch is forced to combat his opponents until he is defeated. You’ll be able to combat up to four different enemies. The Coon, General Disarray, and Professor Chaos are among the villains Mintberry Crunch must fight.

The fight’s fate is determined by the spinning reels. Mintberry Crunch will win his fight if you hit a winning line. As the reels continue to spin, more bonuses and multipliers are awarded for each combat won. On a no-win spin, the different villains zap you to smithereens. As the combat goes, you all get the more bloody and damaged.

However, just as you start to win, Professor Chaos might step up his game. He’s enormous, at least five times the height of Mintberry Crunch. You have no chance of winning. Your cereal is powerless against Anime Professor Chaos’s cape — you earn some money, but you’re on the verge of collapsing since he just blasted you with the most powerful lightning bolt you’ve ever seen – and that’s the end of it. He just kicked you out of the bonus round and sent you back to the reels.

Overall, it’s definitely one of the most entertaining slot games with bonus rounds and you can play at LeoVegas casino.

#2. Flying Pigs

Flying Pigs - slots with bonus rounds

The animation of this slot game is both attractive and a little uncommon for a video slot. It’s similar to a bingo game. Basically, you can buy one to four bingo cards and then release the balls by pressing the “Play” button. The game marks off those that appear on your card/s as they fall from the sky — you can also mark them off manually for added enjoyment.

Corners and horizontal lines are only two of the many methods to win. You can opt to “Buy Extra Ball” at the end of the round if you’re near to winning a line, which might result in a win. The cost of the additional ball is determined by the probability and amount of the possible win.

The Bonus Round

In order to hit it, you must get the bonus pattern, which can be found on the game’s upper left-hand side. You’ll hear groovy music when it hits: “Congratulations. You are the winner of the square. The square is yours. You’ve won the special award in Flying Pigs” – it’ll be stuck in your brain for the rest of the day!

Each pig is worth a certain amount of money. If you accidentally choose a pig that turns into a devil pig, the round ends. The great thing about it is that they are Flying Pigs and that the entire game is super captivating, including the main bingo bit. It’s definitely a white-knuckle game.

Catch Flying Pigs at Vera & John casino.

#3. Red Riding Hood

Red Riding Hood - slots with bonus rounds

This is a relatively new video slot game with bonus rounds and it’s also a fantastic one to play shortly before winter because it emphasizes the season’s mystery and magic – both vital components that make up this fairytale season.

Although this game is a simple reel game, there are lots of possibilities for entertainment. There are, for instance, three categories of “Fairy” additions. On a losing spin, the fairy appears and selects a paying symbol, which turns all of the lesser paying cards into that symbol and continues until you win.

In the Fairy Magic Spin game, the fairy arrives and casts a spell over the reels, converting some of them to a certain symbol. The symbols become stuck and the reels spin again, frequently resulting in a large prize. If you acquire two or more wilds anywhere on the screen, the fairy appears and sticks the wilds in place.

In addition to the fairy bonuses, there are also free spin bonuses and, of course, the bonus game.

The Bonus Round

When three mystery chests appear anywhere on the reels, you are about to enter the extra round. And if Little Red Riding Hood appears with the words “Beware of the Wolf” in one of the boxes, you’ve entered the bonus round.

Then, you’ll be taken to a new screen where you’ll find an adventure board game. The object of the game is for you to spin the wooden board – which effectively works as dice with the numbers 1 to 6. The value of the spin determines how far you advance. When you spin a 3, for example, you advance three places. The multiplier on the space you land on will boost your winnings.

Short cuts and paths may be found across the board, and landing on the “Double” pathway doubles all multipliers. You may sometimes pass over a red X and hear a barking chuckle — it’s the wolf hiding in the bushes. He’s on his way to grab you! You could even witness him pretending to be a sheep and running by!

The goal of the game is to make it to Grandma’s Cottage before the wolf catches up with you. Most of you will not be able to make it to Grandma’s cottage. You’ll scream and jump back in terror when the wolf leaps out from behind a bush, and then he’ll battle you in a cloud of dust – then back to the main reels you are.

It’s actually quite the thrilling game and you can play it at Mr. Green casino.

#4. The Invisible Man

The Invisible Man - slots with bonus rounds

This NetEnt-branded slot has an exciting selection of extra bonus features. When the Police and Griffin Walking Wilds combine, you’ll get 10 free spins. During the free spins, as wilds appear on the reels, they are added to the relevant meter.

The Police Spins bonus is enabled if the Police meter is filled first. Three free spins are awarded, with five Flaming Wilds appearing on the reels at random. Free spins are the most popular bonus slot games.

Griffin’s Rage bonus game is activated if the Griffin meter is filled first. The bonus round takes place at the Lion’s Head Inn, the Mansion, and Epping Station, among other places. You must choose one of five objects from a list of five to receive various coin winnings, increased win multipliers, or a police hat, which signifies the end of the round.

The supplementary elements of The Invisible Man perfectly complement the film’s subject and provide a very enjoyable playing experience. Among the many featuring bonus games, it’s worth mentioning that this slot is of exceptional quality.

You can find the Invisible Man at LeoVegas.

#5. Pharaoh’s Fortune

Pharaoh's Fortune - slots with bonus rounds

There are plenty of slots with bonus rounds, however, this is one of the most favorite and popular ones. That’s because of this genre’s sense of humor as well as a unique and energizing bonus round.

The bonus icon is the golden Pharaoh’s head, and three of them on a payline trigger the free spins round. Before the Pharaoh’s Fortune bonus begins, you must first enter the Pharaoh’s tomb, where you can increase your number of free spins and win multipliers by selecting different tiles.

The hieroglyphic-style figures dance around the reels while the Bangles’ groovy 80’s track, Walk Like an Egyptian, bursts out in the bonus round, which contains a fresh set of symbols.

Furthermore, every spin during the bonus round guarantees a win of at least 3 times the initial stake. The cheerful soundtrack, fun and quirky dancing symbols, and guaranteed winnings make this a great bonus round that will make you happy.

Pharaoh’s Fortune is available at LeoVegas.

#6. Jurassic Park

Jurassic Park - slots with bonus rounds

Come on! Who doesn’t like a Jurassic Park-themed slot (or any type of move-themed slot, to be honest) but with amazing bonuses? Not to mention, this slot game offers a thrilling 5-level additional feature that wonderfully portrays Spielberg’s movie’s concept.

You will be awarded 12 free spins if you land three ambers scatter symbols on the reels. These aren’t just any free spins, either. The free spins bonus will be improved by one of five dinosaur extras, which will be picked at random. Wild Reels appear in the Tyrannosaurus Rex bonus when the T-Rex can arrive and turn up to five reels completely wild.

Multiplier and Split Wilds are created by the Velociraptor bonus round. Running Wilds may be found in the Triceratops bonus. Mystery Multipliers are included in the Brachiosaurus bonus.

Finally, the Winning Wilds feature in the Dilophosaurus bonus includes the dinosaur turning random locations wild. This bonus round is highly thrilling due to the range of creative elements as well as the great graphics, animations, and sound effects.

Jurassic Park can be played at Casino Planet.
