What are these Best Bonus Slots?

People love to play slots online and there is a good explanation for that. It’s entertaining and you can win some serious money with it. Every slot has their own specialty and key features. And when we review a slot we always check if the slot has a Bonus Game. When a slot doesn’t have a Bonus Game I won’t play it. A slot with a Bonus Game is a so-called Bonus Slot.

There are certain people, like us, that only want to play slots when you can trigger a bonus round. Because that is where you can win big and hit some jackpots. But the problem is that not all bonuses are as good as other bonuses. That’s why we want to review the Best Bonus Slots for you.

If you’re looking for the Best Bonus Slots you’re in the right place. We’ve years of experience at online casinos and have played lots of different slots and triggered some great bonuses. On this page you can find all our Favourite and Best Bonus Slots!

Why should you play the Best Bonus Slots?

We all play slots to hit the biggest wins as possible. And there are enough slots where you can win big just by playing the base game. But if you want to win the real money, you have to hit the bonus rounds. Normally the Bonus Rounds are the chances to get some really nice wins and maybe get a maximum win.

When you play the Best Bonus Slots you ensure yourself of the best gameplay and bonuses. When you play normal Fruit Slots you can spin for hours and you’ve played the same game the whole time. And when you play one of the Best Bonus Slots you can hit a couple of Bonus Rounds or other features when you’re playing.

How to Pick the Best Bonus Slots

With so many different options available, choosing the Best Bonus Slot UK can seem like a daunting task. Thankfully, it’s our job here at GamblingDeals to make it easy for you to find the best option. Follow the steps below to get started.

Slots with Best Bonus

Hitting a Bonus is one of the most exciting things when you play a slot. Everybody plays slots to hit a bonus of course, because that’s where you can win the real money. It’s not easy to hit a bonus, but when you do you want a very exciting bonus. That’s why we want to discuss the Slots with Best Bonus you can get. But which is the Best Bonus Slot you can get?

This is a discussion that can go on for hours. Everyone has their own favourites and likes other bonuses. But there’s are some Bonuses that are just to cool or to good not to be in this list. Playing the games from the list below means you guarantee yourself a good bonus. We don’t say you hit the bonuses easy, but when you do you have a good one!

Superstars (NetEnt)

The Superstars slot from NetEnt is a pretty new slot in the business, so it won’t surprise me if you don’t know this slot. NetEnt made this slot with all their most famous characters like Gonzo, Miss Banks, Finn and the Starburst logo.

The Superstars slot has one of the most exciting Bonuses around. When you trigger the bonus round you will enter a complete new bonus board. This looks like a simple board game, but you have tons of features to unlock. When you roll the dice you walk over the board and trigger all these features. Belowe we’ve explain all the features you can find on the board:

The Bonus Features

Superstars-Best-Bonus-Slot

  • Finn Feature – Finn will add 5x up to 5 different boxes on the reels. Then he will combine these prizes into 1.
  • Gonzo Feature – Gonzo can add up to 24 multipliers randomly to the reels. Gonzo can add x2, x3 and x5.
  • Space Wars Feature – The Starship will pick the 3 highest multipliers from the board. You have 3 spins to hit these multipliers in one of the empty boxes.
  • Miss Banks Feature – Miss Banks can add random multipliers up to x5. She can award 15 prizes on the reels and she can also stack prizes on top of each other.
  • Starburst Feature – The Starburst Feature is a multiplier feature. A vertical stack of 3 boxes will be multiplied by the Starburst symbol.
  • Extra Spins Feature – This feature increases the number of spins to 4 instead of 3.
  • Extra Life Feature – This gives you an extra life. So when you run out of spins you have one extra life and the spins counter will fill up again.

The Wheel Game

The last feature is a special one. There’s a Wheel of Fortune you can get. And there are several prizes you can win with this wheel. The most easy one is the ‘Random’ Feature. When the wheel lands on the ‘Random’ Feature you’ll get one of the features above.

When the wheel lands on one of the ‘Dice’ features you will have an extra dice the next round. You can hit 1 or 2 dice extra. This increases your chances of winning good prizes. The +1 feature will add 1 to the multipliers on the reels. So all the prizes you already have collected will be increased by 1.

The ‘Upgrade’ feature is a bit like the +1 feature, but the +1’s will be added on the empty boxes of the board. So all the boxes without a Bonus Round will have a 1 added. When you land one on of these boxes, the values of all the prizes are increased by the value of the box.

The last feature is the ‘Replay’ feature. The next feature you’ll get will be played twice. But this only counts for the following features:

  • Starburst
  • Gonzo
  • Miss Banks
  • Space Wars
  • Finn
  • Upgrade

Red Riding Hood

Red-Riding-Hood-Beware-the-Wolf

Fairytale Legends have a couple slots, but one of our favourites is Red Riding Hood. Red Riding Hood has a very nice normal gameplay. You can trigger a couple of features which make the normal game play much more interesting. It’s not only spinning to trigger the bonus round, because you can win a decent prize when you play the normal game.

But the real reason why we love Red Riding Hood so much is the Bonus Game. You need to hit 3 purple boxes to trigger the bonus round. In these 3 jewellery boxes are three different bonuses. The 3 Bonuses you can get are:

Coin Win

The Coin Win is a not really a Bonus Round. When you pick the Coin Win you will get a certain multiplier. Your bet will be multiplied and that’s your win for the bonus round. This is not the Bonus you want to pick. The prize could be decent, but you always want to pick one of the other bonuses because of the potential. The potential multiplier of these other bonuses is way higher!

Free Spins

The Free Spins Bonus could really explode if you’re lucky enough. You start this bonus with 10 Free Spins. These are just the spins from the normal game with the same prizes, but free. But you can win extra spins and those spins can add up! Every time you hit a Scatter, the purple Jewellery Box, you get 2 Extra Free Spins.

There’s no maximum on the amount of Free Spins you can get here. I’ve seen bonuses where players got over 100 Free Spins. As you can imagine, the prizes you will get in 100 Free Spins can go through the roof! All in all is this a pretty decent bonus, but you do need to hit the scatter often. Those scatters are your way to a good prize!

Beware the Wolf

Best-Slot-Bonus-Red-Riding-Hood

This is the Bonus we all want to trigger! The Beware the Wolf Bonus Round is the most exciting and fun bonus. And the best part is that this also can pay really good! So let’s have a look how this bonus round works. When you got the Beware the Wolf bonus round you enter a Fairytale World full of multipliers. In the upper left corner you find a calendar with numbers on it. These numbers vary from 1 to 6.

Every time you have to spin the calendar and the number you see is the amount of steps you take. The multiplier you land on is yours. On the board you can see x2 multipliers, but also x40 multipliers. But those multipliers are harder to get. Sometimes you have to be lucky and land on an arrow. This arrow will locate you in a different direction. This hidden paths have higher multipliers, but also more X’s.

The bonus round will end when you hit a X on the ground. As long as you don’t hit the X you can pick up multipliers along the way. This could add up to some pretty high multipliers!

The Dog House

The Dog House if a very well-known game for most of you. Everybody has seen or played this game at least ones in their lives. The graphics of this game are extremely good, because who doesn’t like cute puppies? Spinning the slot means you can win some nice prizes, but of course you want to hit the bonus round here.

You can get into the bonus by hitting 3 Bonus Symbols. This is the yellow with red Paw Symbol. These Scatters can only land on reel 1, 3 and 5. So you have to hit the Scatter symbol on all these 3 reels. Hitting the bonus means that you will get a 5x immediately, that is called Scatter pay.

Spinning for the amount of Spins

The first thing you have to do when you enter the bonus game is spinning for the total amount of spins you get. You see a 3×3 board with 9 rolls. All these rolls have a value from 1, 2 or 3 on that roll. If you count up all the numbers you have the total amount of spins for the bonus.

So for example you have 5 times the ‘1’ and 4 times the ‘2’. Now you have in total 13 Spins. This is a pretty decent amount of spins for this bonus.

The Bonus

The-Dog-House-Bonus-Slot

When you enter the real bonus round you have to look for the ‘Wilds’. In Dog House the Wilds are the Houses with multipliers on it. Normally when you play a the base game you can also get these Houses with multipliers. But in the base game they don’t stick.

But when you play The Dog House Bonus the Wilds are Sticky Wilds. So every wild you hit will stay in that position for the rest of the bonus. The goal of the game is to hit as many Wild Multipliers as possible. And the earlier you get them, the better. You want as many spins possible with the most amount of Wilds.

The Wild Multipliers can only land on reel 2, 3 and 4. So if you manage to get the a Wild on reel 2, 3 and 4 in the right order you have almost a full line for the rest of the bonus. So it’s also really important that the Wild symbols will land in the right place. This will guarantee some nice winnings!

Money Train

Best-Bonus-Slot-Money-Train

Money Train is an established name in the slots market. There are already 4 Money Train Games, that shows the popularity of this game. The reason why this game is so extremely popular is not because of their normal game play. This is just like other slots and not very exciting. The best part about this slot is by far the bonus game. Everyone is playing this slot to trigger the bonus games, because that is where the real money is made!

When you hit 3 ‘Bonus’ symbols you trigger the bonus round. You start the bonus round with a 5 by 4 screen with 3 multipliers in it. You have 3 spins to hit a new multiplier or other symbol to restart the spin counter.

The goal of the bonus is to increase the multiplier as high as possible. You can do that by hitting the following symbols:

Symbols

  • Multiplier – This is the simplest symbol you can get. The multiplier symbol will add to your total multiplier, but doesn’t do anything else.
  • Payer – The Payer symbols will have a multiplier added to them. The Payer will give this multiplier also to all the other symbols on the board.
  • Collector – The Collector symbol will collect all the multiplier on the board plus his own multiplier. The current multiplier will be doubled by the collector symbol.
  • Widener – The Widener will open up more reels with his dynamite. These extra reels mean you have more chances to hit extra Multipliers, Payer or Collectors. The more Widener you get the more reels will be opened for you. The Widener self has also a multiplier that will add to the total multiplier.
  • Persistent Payer – This is one of our favourite symbols to get. This works just like the normal Payer, so every box will get the multiplier on the Persistent Payer box. But every spin the Persistent Payer will pay the symbols again. The longer the bonus will last, the more the Persistent Payer will pay.
  • Persistent Collector – A Collector is a familiar symbol, but a Persistent Collector is a better symbol. Just like the Persistent Payer the Persistent Collector will collect all the multipliers every spin. When you have a filled board you can collect extremely high multipliers every round. A long bonus means that the Persistent Collector can collect more multipliers!

Does all Slots have a Bonus Round?

While bonus rounds are a common feature in many modern video slots, especially those with more elaborate themes and gameplay mechanics, classic slots typically do not include bonus rounds.

You might think that all slots have a bonus round or some other special round. When you play Video Slots at an online casino they try to attract you with amazing bonuses and high payouts. But not every online slot has a Bonus Round. It’s pretty rare that an online slot has a good bonus round. That’s why we reviewed the Best Bonus Slots for you!

It’s essential to note that not all modern video slots have bonus rounds either. Some developers focus on creating simpler slot games without elaborate bonus features, catering to players who prefer a more streamlined gaming experience. Additionally, some classic-themed video slots may incorporate bonus rounds or special features while still maintaining the overall feel of a traditional slot machine.

Classic Slots

The first slots that are created are still some of the most popular ones. Classic casino slots, also known as traditional or retro slots, are the earliest form of slot machines found in land-based and online casinos. These slots typically feature three reels and a single payline, although some variations may have multiple paylines. Some of the most popular classic slots are Starburst or even Book of Dead. In the past they didn’t care about Slots with Bonuses. For example, Starburst is the most played slot, but doesn’t have a Bonus Round.

Classic Casino Slots are known for these key features:

  • Simple Gameplay: Classic slots usually have straightforward gameplay with minimal features. Players spin the reels and aim to match symbols along the payline to win prizes.
  • Symbols: The symbols used in classic slots often include traditional icons such as fruits (cherries, lemons, oranges), bars, lucky sevens, and bells. These symbols are reminiscent of the original mechanical slot machines.

Fruit Slots

The most Fruit Slots have just the reels you see on the screen and don’t have the Bonus Rounds. You might know these Fruit Slots from the local bar of gas station. When you play in the bar you also can’t get the Bonus Rounds.

Fruit Slots are the most classic and easy way to play slots. The payout of the game is also way higher in comparison to the Video Slots with Bonus Games. That’s the reason why you can win extremely good prizes when you just spin the reels. 3 symbols in a row can already pay 8 times your bet. And the symbols pay all a bit the same.

If you want to play Slots without a bonus that still pay good, Fruit Slots are the way to go. The RTP is relatively high and the volatility is low. So, the perfect game to play if you like to spend some time in the casino, but don’t want to lose a lot of money.

Welcome Bonus Slots No Wagering

Some of the Best Bonus Slots are the Best Slots Welcome Bonus No Wagering. These Best Slots Welcome Bonuses No Wagering are pretty rare on the market. I only know a couple online casinos that give away a bonus like that. But what are the Best Welcome Bonuses No Wagering?
