Dead or Alive II – NetEnt 

1_Dead or Alive II

Online slot games have radically transformed in recent years, adding themes, special features and aesthetics. Among these, Dead or Alive II, developed by NetEnt, transports players to the rugged landscape of the Wild West. 

This high-variance slot game attracted numerous Irish and non-Irish players with its multiple bonus features. 

Dead or Alive II features

The game includes five distinct wild symbols that have their own reel. You can locate the Billy on reel 5, Belle Star on reel 4, Jesse James on reel 3, the Della Rose on reel 2, and Apache the Kid on reel 1.

Landing five wilds on a pay line will pay out 166.66 times your bet. 

Dead or Alive free spins

As every reputable online casino offers free spins bonuses for Irish players, games also have these. This game is at the top of our list because you have multiple free spins bonuses to choose from. 

The rule to select your desired mini-game is to land three scatters. This way you’ll activate the free spins. If you have five scatters, you also earn 2,500x your bet. You get 12 free spins for one of the following features on both occasions.

Train Heist

There is a wild counter above the game’s reels, and this option boasts the lowest volatility. Each wild symbol that appears on your screen is a 1x multiplier and grants another free spin. You get extra five spins with a maximum of 16x multiplier besides the ones already given. 

Old Saloon

Just like the previous bonus, it has medium volatility and offers a 2x multiplier, and if you have the wild on all five reels, you also get five extra spins. 

High Noon Saloon

The high-variance option comes with sticky wilds and multipliers of 2x or 3x, depending on the symbol and number of icons on your reels. You get five additional spins for a sticky wild on every reel. The maximum you can win is 40.500 times your initial wager.

Starburst – NetEnt


From the moment players launch Starburst, they are greeted with a visual spectacle that mirrors the brilliance of a cosmic display. The game’s vibrant colours, sparkling gems, and cosmic background created an impressive trend, and after more than ten years, people are still really into this non-progressive slot game. 

Starburst data 

This low-volatility game allows you a maximum win of 500 times your initial stake. The minimum bet is 0.10 coins which is a great value for Irish players who want to play responsibly and stay on a budget. However, it is also a great game for people who wish to increase their free spins value

The usual NetEnt slots are filled with dazzling perks and amazing effects, but Starburst only has one bonus feature, which makes it stand out more. 

Starbursts extra spins

The game doesn’t have dedicated free rotations bonuses, but the Starburst Wild feature grants you re-spins with sticky symbols. However, the expanding Sticky Wilds re-spin makes people still play the game. 

This extra feature can appear on reels numbers 2,3, and 4, and the idea behind it is to make them expand and capture the entire screen. While the Sticky Wilds remain in place, the other reels respin, increasing your winning potential. 

Where can you play Starburst? 

Starburst is one of the most played non-progressive slots of all time, so all significant casinos should have it. Moreover, some casinos like Skol or Space Wins offer Starburst free spins on registration

Gonzo’s Quest – NetEnt

3_Gonzos Quest

The third NetEnt title comes with plenty of features and amazing graphics. This is the first slot game transformed for VR gaming after being well-adapted for mobile devices playing, and this made even more people willing to try it out. Most new Irish casinos offer demo versions for Gonzo’s Quest, so you can understand the theme and how the game works before adding real money.

Gonzo’s Quest Features 

The Mayan-themed slot has a maximum winning potential of 3750 times the initial stake and medium-high volatility. Twenty paylines and an RTP of approximately 95% define this game as suitable for many gamblers. 

It provides Avalanche, Wilds, Multipliers, and Free Spins rounds for the curious. 

Cascading reels 

Gonzo’s Quest Slot is recognised as one of the pioneers in introducing cascading reels to the world of online casinos. Avalanches or cascading reels can lead to consecutive wins from a single spin. 

The symbols involved in the winning combination explode, making way for new signs and creating a cascade effect with more significant chances of winning. Each explosion increases your multiplier up to 5.

Free Falls 

Complementary rotations are called “Free Falls” because the Mayan symbols are falling rather than spinning. If you have three Free Falls icons on a payline, you get ten spins. If you’re lucky enough to get three or more on two separate lines, you get 20. 

Gonzo’s Quest is not hard to find

Book of Dead – Play’n Go

4_Book of Dead

Another classic non-progressive slot, but from a different provider – Book of Dead, gathers around gamblers who adore Egypt and adventure. The game started controversies because it might appear too similar to Book of Ra from Novomatic, but the games have distinct features. 

You can win up to 5000x your initial bet and bet as low as €0.01 up to €100. The game’s scatter symbol is also the wild icon, so keep an eye out for it. 

Gamble Feature

The classic slot machines usually have an additional game called “Black or Red” that allows you to double your winnings or lose all. This game also has this feature. After a win, you can try to guess the cards’ colours and see if you’re lucky enough to quadruple your funds. 

It is not mandatory, so you can simply ignore it and continue the game. 

Book of Dead Free Spins

When the book appears on your reel, it can give you ten free spins if there are three of them. Additionally, if you land on the scatter during these ten free spins, you will get more.

Big Bass Bonanza Megaways Slot – Reel Kingdom

5_Big Bass Bonanza 

Big Bass Bonanza grew in popularity fast due to its fishing theme and 4000 times potential win. The game is easy to understand and interesting to play. So, without further adding, let’s see what features this game offers.

Free Spins on Free Spins 

If you get between three and five golden fish scatter symbols, you get between 10-20 extra rotations. When you’re on a winning streak, the icons will fall off instead of disappearing, and the Fisherman will collect all the cash value from any similar fish. 

The Fisherman Wild grants you another ten free spins and becomes a multiplier if you get four of them. In the luckiest situation, the multiplier gives your ten times the value and up to 50 complimentary rotations. 

During the bonus rounds, you also get two special icons: The Dynamite that adds random fish and the Bazooka that explodes all the symbols except the wilds. 

Can you find casinos with Big Bass Bonanza Free Spins?

Yes. The game is so popular that many casinos have no deposit offers for the game. Moreover, some casinos like PowerUp or LuckyDays have welcome offers with Big Bass Bonanza spins.

Thunderstruck II – Microgaming

6_Thunderstruck II

Although Thunderstruck is not the most popular Microgaming slot, its features are amazing. You can win up to 8100 times your initial bet, and the game has four different types of free spins features and two additional mini-games to keep you engaged.

Thunderstruck II Free Spins

The Great Hall of Free Spins is the first step that connects you to your biggest wish. The game’s inspiration from Vikings and Northern Europe culture can be observed. This Hall of free spins is given to all mighty Vikings that died with dignity. The more times you see it, the more features you unlock. 

Valkyrie Free Spins Bonus is your first entry and the first God that grants you 15 additional spins with a 5x multiplier. The Loki Free Spins Bonus gets you another 15 rotations, and due to its tricky nature, this God will transform random symbols into wilds to make you win. 

When you meet Odin, you’ll feel his ravens’ blessings. The ravens will randomly come and multiply your lines with up to 6 times the value while getting 20 spins. 

The last God is Thod, the God of Thunder grants you 25 rotations after you visit the Hall at least ten times. As you spin the free rounds, the symbols tumble down and multiply your winnings up to five times.

The Holy Grail Bonus feature is what makes this game stand out because it can unleash one of the eight extra bonuses. You can activate the Holy Grail by landing at least three Holy Grail scatters on your reels.

Legend of Cleopatra Megaways gameplay

The game offers cascading reels with twists. If the top three symbols are a winning combination, each scarab on the screen will increase the multiplier by one. 

In a cascading sequence, these symbols do not disappear and have the potential to keep on accumulating and give you 12 free spins. 

You also have a scarab multiplier that sticks in place and gives you five spins when you clear the top horizontal line completely. You can clear it by having the same symbols in the same spin. 

Hotel Yeti Ways – Play’n Go

9_Hotel Yeti Ways

Hotel Yety Ways is one of the most remarkable summer slots you’ll see. You can win a maximum of 30000 times your initial bet, but if you’re not that fortunate, you can simply enjoy the game and eventually find it in the no-wagering bonus section

The game has a high variance and 4096 paylines, but the wild symbols are the most important. The Ice Wild helps you create winning combinations, and the Yeti lines do the same but also trigger one of the three cool summer activities that might make you richer.

Yeti activities

Bungee Jumping gives you up to four reels full of wilds. Surfing Yeti will randomly place up to eight wilds on your screen.

Scuba Diving gives you respins. If your respin gets a shark symbol, then you get another one. You can get up to 24 respins and a screen full of sharks because they remain in place during these rotations. A full picture pays out 12,288 times your initial wager. 

The more scatters you gather, the more free spins you get.

Pets Go Wild – Skillzzgaming
