Best Slot Bonus Games
Creeping into the top 10 of best bonus slots is Elk Studio’s Wild West inspired number, Black River Gold and there’s plenty of action going on beyond those spinning sheriff badges. The Avalanche wins feature in this game means that the rows can expand up to 8 rows to give you up to 262,144 ways to win. Basically, this type of online slot machine gives bonus spins when you land 3 or more symbols. Although most popular games offer this, Machina Megaways is one of the more recently launched examples of this. It also has a pretty fair RTP percentage of 96.59 - 97.42 and a perfect slot for high rollers looking to land a big win. Bonus games and features can make playing online slots more enjoyable, and can give you the chance to win a whopping jackpot! This guide to bonus games covers everything you need to know about slot machine bonuses, the best slots with bonus games to play online, and where to play for free and real money! The first slot machines the world ever saw didn’t really have any slot bonus rounds or extra games, and we’re not sure the likes of Charles D. Fey even envisioned that this was possible back in the late 1800s.

The bonus slots, also known as video slots with bonus rounds, are one of the most popular slot machines online.

Find below a collection with some of the best free slot games with bonus rounds and play online for free, no registration required!
Slot Games with Bonus Rounds
Slot games, in general, can be divided into online slots with bonus rounds and online slots without bonus rounds.
Slots with bonus games are usually more attractive for players and more fun to play because of the bonus rounds. They’re exciting because you’re always waiting for the bonus round to land and always expecting to win big in the bonus round.
All bonus slots usually have an explanation what the bonus round is about in the game rules. If you want to see what the bonus round is first hand, it’s best to try the games in the free mode first.
How do slots with bonus rounds work?
In order to see what a bonus slot is all about all you need to do is to sign up for an online casino and play the game for free. It’s the same as playing for real money. The only difference is, you don’t have to invest any money. You can read the game rules and the bonus round rules and once you feel comfortable with the game, you can give it a try in the real money mode.
In most video slot games, the bonus round is triggered when three or more scatters or bonus symbols appear on the reels. Once this happens, the bonus round starts and all you can do is to enjoy the privilege and hope to win big.
In general, the bonus rounds are divided into free spins and cash pick bonuses. The free spins bonus is a rewarding round where a player gets a certain number of free bonus games. There are also some other features like multipliers, extra wilds or expanding wilds. The cash pick bonus game usually awards cash prizes for every pick on the reels.
How to win big in the bonus games
One of the most fun features in the online slot machines is the bonus rounds. You get to view secret graphics and gameplay and you are usually given a chance to multiply your potential winnings.
However, did you know that there is a strategy for making the most of these opportunities?
If you don’t believe us, just check out the following…
1. Know your slot
Become familiar with your game and get an approximate feel for how often the bonus round appears. That way you can gauge if the game is being generous or stingy with bonus round appearances when you’re in the midst of playing it. If it’s not giving out too many, it may be time to move to a different slot as the first step to making the most of bonus rounds is actually getting to play them.
2. Use a bonus round hunting strategy
Many professional gamblers sight ‘bonus hunting’ as their chosen strategy when playing online. The beauty of this strategy is its simplicity; play a game until you get a bonus round, win and then leave.
The theory behind this is that you’re leaving every game after getting a reasonable win and each one of those wins add up to increase your overall bankroll, thus giving you more money to hunt more bonuses.
3. Play every line
Of course, it makes sense that you should try to maximise your chances of getting into these bonus rounds. One simple way to do that is to play every line. There are games that only offer bonus rounds to those who max bet, so if your budget is low, give the penny slots a lash and you never know, you might be playing with a bigger bankroll before you know it!
Best Online Slots with Bonus Rounds
There are a lot of great free casino slot games with bonus rounds which have amazing rewards. On some video slot games, the bonus round is incredibly hard to trigger. Still, once this happens the payouts are usually big. These are high variance slots which can pay big in the free spins bonus regime.
Microgaming has a lot of great bonus slots on their offer. Thunderstruck II and Immortal Romance share an almost identical free spins bonus. Once you enter the chamber of free spins you can unlock four different features and choose among different free spins modes.
NetEnt also has a big number of slot machines with bonus rounds. Their most popular video slot game Dead or Alive has a free spins bonus with a sticky wilds feature. Once 5 Wilds land on the reels, the player gets 5 extra free bonus slot games. Win a wild line and the payouts can be well worth the try.

Bonus Rounds Slots FAQ

What are the luckiest slot machines?
Best Slot Apps With Bonus Games
Some players may view this as a good or bad thing, but there is no such thing as lucky or unlucky slots. Modern, regulated slots are driven by unemotional Random Number Generators. These math models are completely fair, random and unpredictable.
It is possible to have runs of wins or loses, but this does not make a slot lucky or unlucky. Some slots have paid out more than others, such as Mega Moolah. But this is due to their bonus system, and the algorithms that govern play. Never luck.
What are branded slots?
Branded slots are slot games that use some type of famous element in their theme. This could be anything from movies, TV shows, video games, board games, cartoons, bands, and more. Branded slots are popular because they are instantly recognisable and relatable.
When it comes to bonuses, wins, and gameplay, it doesn’t mean they are necessarily better than non-branded slots. But there are some cracking good examples of branded slots all the same.
Are slots random?
Modern slots offered by licensed providers are completely random. Developers power their products using Random Number Generators that ensure that every spin is completely unaffected by the spins that preceded it. For extra peace of mind, online slots and providers are tested by third-party auditors as part of licensing requirements. This ensures that slots are totally fair and random.
Which slot machines have the highest RTP?
When it comes to RTP, 96% has become the unofficial industry average. Anything above that is considered good. Anything under that not so good – depending on how much less of course. The great thing for players is that there are loads of slots that score higher than 96%.
Some excellent examples that were released quite recently include Jackpot 6000 (98.9%), and Mega Joker (99%) both from NetEnt. Another generous slot is 1429 Uncharted Seas (98.6%) from Thunderkick and Retro Reels Extreme Heat (97.5%) from Microgaming. RTP is always a critical stat we look at when reviewing slots.
Do casinos manipulate slot machines?
Regulated, legitimate casinos do not manipulate slot machines. Slots machines have a house edge built-in, so there is no need for anyone to manipulate them. Regulated casinos have slots tested by independent auditors to prove that their slots produce the results they state.
If a casino was accused and found guilty of manipulating slots they could go out of business. It is just not in their interest to manipulate their slot machines.
Should you max bet on a slot machine?
You should only max bet on slot machines if it suits your bankroll limit and betting style. In the past, some slots would only trigger jackpots or bonus features on max bet. Nowadays, this is virtually non-existent.
Now, bet levels of any size have the same chances of launching bonus rounds, free spins, and jackpots. This also includes hitting progressive jackpots. Of course, you should always read the paytable of any new slot to make sure you are clear on the rules.
What if — one day — you entered a slot machine bonus round and walked out $15,000,000 richer? For some lucky players, that has actually happened.
Long gone are the days when you spun 3 reels with fruit symbols on them and won a few free spins as a bonus round. These days, there are all sorts of awesome, entertaining bonus rounds which make video slots appear more like video games.
I’ve played thousands of slots in my time, and thousands of bonus rounds, too. I’m going to share the best I’ve encountered here.
Unsurprisingly, most of them give you the chance to win huge amounts of cash, which is part of what makes them so great to begin with!
The Mega Fortune Bonus Wheel
When it comes to slot machine bonus wheels, most people think of Mega Moolah by Microgaming first. While that is a pretty cool feature, I personally think the Mega Fortune bonus wheel is slightly better.
This is a feature that will get your adrenaline pumping for sure. It’s a multi-layered wheel with cash prizes and several progressive jackpots up for grabs.
So, how do you win the Mega Jackpot and walk away a millionaire? Each time the wheel spins, you need to land on an arrow to proceed to the next layer. If you make it all the way to the center, you can officially call yourself filthy rich.
This feature can actually be triggered fairly often in Mega Fortune. A few days ago I was able to unlock it 3 times within the same quick session.
The Scary Rich 3 Free Spins Round
Unless you’re a hardcore slots player like myself, you might never have heard of Scary Rich 3 from Rival Gaming.
It’s a horror-themed slot which is relatively unremarkable overall, apart from the cracking free spins bonus round. If you manage to trigger it with 5 scatter symbols you will get 666 free spins, which I can tell you from experience takes around half an hour to play through.
While that’s a heck of a lot of free spins and is enough to make this bonus round noteworthy by itself, there are also expanding wilds in play throughout. These significantly increase your chances of making winning combinations.
As I said before, it’s one of those slots few have heard of, but I have personally never seen another slot offering as many free spins in one feature.
The Avalon II Grail Bonus Feature
Sometimes a bonus feature is actually multiple bonus rounds all rolled into one, and that’s the case with the Grail feature in Avalon II from Microgaming.
If you manage to trigger this feature, you will have 8 different entertaining possibilities. There’s a dice roll game, 3 free spins rounds with up to 20 free spins and dynamic multipliers in one of them, 2 picking rounds with up to 160x your stake available, a fighting game with cash prizes, and a bonus wheel round, all within one feature.
This feature also has somewhat of a storyline to it, in which you need to retrieve ”the grail” and bring it back to Avalon. It’s got epic graphics and sound effects, which I have come to expect from Microgaming.
Why do I like this feature so much? Because it doesn’t get boring even when you trigger it multiple times within the same game. Oh, and you can win serious money, too.
The Breakaway Free Spins Round
Breakaway is an ice hockey themed game from Microgaming. It’s got loads of extra features, but the one which stands out most to me is the free spins round.
There are up to 25 free spins offered, which is nothing remarkable in and of itself, but all wins are instantly boosted 1,000% by a 10x multiplier.
Breakaway has a 125,000-coin jackpot, which is also worth playing for. Still, this is all about bonus rounds, and I definitely want to mention the free spins round here. Multipliers of 2x and 3x are common, but 10x deserves a special mention.
If the ice hockey theme doesn’t appeal, then either Football Star or Rugby Star also have free spins rounds with 10x multipliers. Check them out.
The Hall of Gods Picking Feature
Hall of Gods by NetEnt takes you back to the mythical era when Odin, Loki, and Thor ruled the minds of the Nordic people.
Thor’s hammer is a symbol we still recognize today, and it’s an important one in this bonus feature. How it works is that you take Thor’s hammer and smash various shields on the screen for cash prizes.
What makes this relatively simple feature so special? The fact that you can win millions instantly by finding one of the Hall of Gods progressive jackpots behind the shield you smash.
This feature has the power to make you a millionaire in a few seconds flat, and I think that makes it special, even if I haven’t yet had the good fortune to win it.
The Gonzo’s Quest Avalanche Reels
Gonzo’s Quest is one of NetEnt’s most popular slots of all time. It’s a simple game, but it has one brilliant feature I really like.
The “Avalanche Reels” make it possible to win multiple consecutive times off one single spin. This means that when you create a winning combination, the symbols involved disappear and are replaced by new ones, potentially unlimited times in a row.
While this is not totally unique in itself, Gonzo’s Quest adds extra spice to the rice by adding a dynamic multiplier element. For each consecutive win, a multiplier will increase by 1x, up to a maximum of 5x.
Just imagine 5 wins in a row from one spin, with the fifth win boosted 500% automatically (after all the others). That’s why this feature deserves to be included on this list, in my view.
The Mega Moolah Bonus Wheel
Best Slot Bonus Game
There’s no rule against having two entries for great slots bonus wheels, right?
While I stated clearly above that I feel the Mega Fortune bonus wheel is the best of the lot, the Mega Moolah one is still pretty immense.
This is more of a traditional bonus wheel, meaning there is just one layer to it. There are 4 progressive jackpots which can be won, starting with the Mini and going all the way up to the Mega.
Best Slot App With Bonus Games
If you’re lucky enough to land the Mega jackpot, welcome to the millionaire’s club! Mega Moolah is renowned for paying out ridiculous jackpots more suitable for a state or national lotto draw than a slot machine.
