Best Slot Bonus Features

Big win banner background for online casino, poker, roulette, slot machines, card games.

When you’re looking for a new slot to play you likely have various things that you look for which will make it attractive to you. You might have a particular designer in mind or a specific type of bonus game that you enjoy or have been lucky on previously. Below we’ll list the best online slot bonus games and modifiers which we have enjoyed playing the most recently.

1. Wizard of Oz Ruby Slippers Slot (Ruby Slippers Feature)

There’s a couple of bonuses here which we love. The first is called The Ruby Slippers Feature. Here bubbles float onto the screen randomly from any base game spin (so long as the Jackpot symbol doesn’t land on reel 3 or any of the character symbols on reel 5) and pop on the reels turning them into Wild Reels.

There can be up to 4 bubbles float in and turn reels Wild to make for some massive wins. You’ll also get either a 2x or a 5x multiplier on your win and if you’re super lucky Glinda the good itch will appear and give you a nice 10x!

This is one of the best slot bonus features as it really spices the game up as you know it can spin in at any time and you’re always hoping to hear the magical “What’s happening” line from Dorothy as you know the bonus if being triggered. 

Recommended casinos to play at are Lucky Nicki and PlayOJO.

2. Genie Jackpots (Genie Wilds)

This is a similar bonus to the one above and it works by a Genie flying out of the lamp onto a reel and turning it into a Wild Reel. The Genie can land on any given reel 5 times and each time it lands on the same reel the multiplier is increased by 1x up to a maximum of 5x.

This can be triggered from any base game spin and only applies to that single spin. It’s one of 4 “power spins”available on this slot but is by far the best and we like it even more than the free spins bonus rounds. It’s certainly a slot which we have enjoyed playing and gives some serious entertainment value, ranking it up there with the best slot bonus features.

We recommend playing Genie Jackpots at King Billy Casino.

3. Rick and Morty Megaways (Vindicator Free Spins Bonus Round)

The latest Megaways offering which we have thoroughly enjoyed and found to have some of the best bonus features available is the Rick and Morty slot. Here you have a choice of free spins bonus games but our favourite is the Vindicator Spins. Ideally during this bonus game you want to land the Vindicator symbol on the top special reel above the normal reels.

When this happens any gold reels with monetary values will get locked in place and if they keep spinning in you get the combined total of all the reels. If you get another Vindicator symbol on the special reel you also get an extra 1x multiplier for the overall win.

Add to this that you can land in one of 4 different Vindicator figures with a monetary value attached and you have a quality bonus game which we have been pretty lucky on.

We Recommend Playing Rick and Morty Megaways at Lucky Nicki and PlayOJO.

4. Dead or Alive 2 (High Noon Free Spins)

Coming with 3 different 3 spins bonuses to choose from when you land in 3 Scatter symbols, if you go for the High Noon option which is the most volatile, you’ll be in for some potentially huge wins of 100,000x times your stake.

Here you’ll get the chance to land Sticky Wilds with multipliers and the chance for 5 extra free spins if you get a Wild on all reels.

There have been numerous huge wins with this bonus feature making it near the top of many players favourite online slots lists. Perhaps the finest slot game from NetEnt yet.

We recommend playing Dead or Alive 2 at King Billy Casino.

5. Rainbow Riches (Road To Riches Feature)

This is an old favourite slot game of ours and perhaps one which was most popular in the UK. It has 3 different bonus feature games but the iconic one is the Road to Riches which is triggered by 3 Leprechaun Scatter symbols.

You’ll be taken to a screen showing the Irish countryside with your Leprechaun character looking to travel all the way to the Pot of Gold at the end for a maximum of 500x your stake.

Each time you spin the wheel it’ll land on numbers 1 to 6 or on Collect, the more numbers you land the further along the path you travel and the higher the multiplier gets.

Many people may feel that this doesn’t qualify as one of the best online slot bonus games as it can perhaps feel a bit dated but it is certainly one of the bonus rounds which we have most enjoyed over the years.

Recommended Casino to Play Rainbow Riches is PlayOJO.

6. Sausage Party Slot (6 Bonuses + 6 Modifiers)

We couldn’t pick any single bonus game on this recent offering from Blueprint gaming as it’s simply packed full of bonus rounds and modifiers which keeps things highly entertaining. It’s most definitely on our list of the best slots with bonus games and well worth trying out. It can be somewhat volatile however, but when it pays out it’s an absolute delight.

Recommended Casinos to Play Sausage Party Are Lucky Nicki and PlayOJO.
