Three Most Popular Free Slots

Below are the current three most popular online slot games, each game offers you a completely different type of slot playing experience, however, they all give players the very real chance of winning some huge amounts of cash!

Avalon 2 Slots – The Avalon free slots game is one of the most recent offerings from Microgaming. Using a 243 ways to win payout system, you’ll find plenty of winning combinations on this slot. There are also stacked wilds, free spins, a huge variety of bonus games including a dice game, a randomly triggered multiplier, picking games and if you’re very lucky, scatter pays that can be absolutely huge! Because this game runs on the All Ways engine, you aren’t able to reduce the number of lines you play, however, you are able to alter the stakes, and as such, you can play for very small amounts.

The jackpot on this slot is won when 5 wild symbols appear on the slots reels this will then award you with 100 coins per combination, meaning that a screen full of these symbols would award you with 243000 coins! During the base game, Merlin may appear to award you with extra wilds, or bonus credits, and quite often when he appears the bonus awarded is truly huge! There is a bonus expanding wild on the third reel, and when this spins into view, it will expand turning the entire third reel 100% wild!

Thunderstruck 2 Slot –  Thunderstruck II is another of the later offerings from Microgaming, running on a similar engine to the Immortal Romance slot, also from Microgaming, this game has 243 ways to win as well as plenty of Wilds, scatter symbols, 4 free spins bonuses and a randomly activated Wild Storm bonus.

As the game has stacked wilds, you’ll be able to create plenty of wins, and should you spin a screen full of Thunderstruck II wild symbols, you’ll be awarded 2.4 million coins! The Bonus Warhammer symbol will trigger the Great Hall of Spins, and it’s here that you can unlock one of 4 types of free spins bonus:

Valkyrie Option – This option offers 10 free spins with all wins multiplied by 5.

Loki Option – 15 free spins with Wild Magic feature.

Odin Option – 20 Free Spins with Wild Raven feature.

Thor Option – 25 Free Spins with Rolling Reels feature.

The key to unlocking these free spins is by triggering the free spins bonuses. After a set number of triggers, you’ll unlock the next and the next. The initial sets of free spins you trigger are the Valkyrie spins, and these do offer some huge potential for winning big!

There are stunning graphics on the Thunderstruck II slot, and the audio is of studio quality, so we recommend that when playing you crank up the volume and immerse yourself in Thunderstruck II!

The Dark Knight Slot – Are you ready to return to Gotham?

The Dark Knight slot is another of the popular slots from Microgaming, and this slot comes in two flavors, the Stand Alone, and the Mega Moolah progressive slot. They both play and pay identically. However, the Mega Moolah progressive does give you a random bonus and a fair crack at winning a progressive jackpot.

You’ll find all kinds of fun features in this slot including scatters and stacked wild symbols. There are also free spins up for grabs with a multiplier starting at x2. These free spins are triggered when 3, 4 or 5 Joke symbols spin into play and they will also award credits of 300, 1500 can 15000 coins respectively. During the free spins, a special reel set comes into effect that gives you an even bigger chance of winning!

Being a 243 All Ways slot, you have no paylines, simple spin 3 or more matching symbols into view from the leftmost reel to be awarded with that symbol’s corresponding prize! If you have never played an All Ways slot before, we are sure you’ll have no problems becoming accustomed.

We do warn you however, this game is quite a High Variance, which basically means that you will occasionally go through a dry spell when it comes to winning, however when the reels fall your way, you’ll have tons of winning combinations spinning in!

Mega Moolah Slot

Now, for the Mega Moolah bit, the Mega Moolah feature round is a randomly awarded game. At the end of any given spin, the game may go into lock-down, and a new screen pops up. You are then tasked with choosing your side, the Joker, or Batman.

After choosing the wheel will spin, and whichever prize portion lands on your marker is the prize you have won. The Mini jackpot starts at a modest 10 coins, the Minor 100, the Major 1000 and the Mega progressive jackpot starts at a massive 1000000 coins! This is by far one of the most popular Mega Moolah progressive slots, however, if Batman isn’t your thing, there are a variety of other games in the range including Mega Moolah, 5 Reel Drive, Summertime Slot and more.

These games all offer different win-lines, playing stakes, themes and colour schemes, however, they are all linked into the Mega Moolah progressive, so at any given time, when playing any of these Mega Moolah slots, you could be walking away with far more than you bargained!

As mentioned above, not all progressive slots work like this, and some do need you to place a maximum bet, however, this isn’t required with Mega Moolah, as you always have a chance of getting a progressive jackpot.
