More than 25 FREE slots with large smoothly animated reels and realistic slot machine sounds. Play FREE and WIN CASH!

The best online slots are the source of excitement and enjoyment for players. When it comes to free slots, the size and frequency of payouts don’t matter because you can’t really win anything when playing in demo mode. When choosing a free slot, you need to consider other factors, such as design, plot, theme, and extra features.

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. Slots casino gratuit 2021 download.

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

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.

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.

These are my favorite slot machine bonus rounds. I’d love to hear what yours are. Leave a comment below to tell me about them so I and other readers can check them out for ourselves.
