Ghost Pirates: A Pirate's Afterlife of Boo-ty and Spooks

Many pirate-themed slots have been released over the years, but this one comes with a twist: all the pirates involved are ghosts. I was impressed with the complex artwork in the game. In the background, you’ll see two sword-wielding pirates on the ocean, seemingly at war. The clear reels will give you a good look at the amazing art. 

I also found the choice of symbols quite interesting. There’s a pirate who looks like he’s from the 1600s, a creepy old witch, a monkey, an anchor, two guns, and a bird. The blood-curdling sound effects complement the game design perfectly. It’s something you can expect to hear in the Pirates of the Caribbean movies. 

Even with the complex design, Ghost Pirates is very easy to play. Start by setting the number of ways of winning (3, 9, 27, 81, or 243). You can also turn on the quick spin function and use the spacebar to spin the reels. Still not happy? Then go ahead and turn on the auto-spins feature to automate up to 1000 rounds. Remember to add the win or loss limits. 

I was able to trigger the free spins bonus many times in my gameplay, and this helped me generate substantial profits. So, how many free spins are offered? Well, this depends on the number of ways of winning you choose. With 243 winning ways, you’ll get up to 25 free spins, and the number will be lowered to 25 for the fewer bet ways. The cherry on top is that the game applies a 3X multiplier to all free spins winnings. 

To sum up, Ghost Pirates is one of the best-designed slots I’ve ever seen. The artwork is sharp and goes well with the creepy soundtrack. I was also able to trigger the free spins bonus numerous times, and this helped to boost my wins in the game. The fact that it comes with a 3X multiplier was also impressive.

PROS

• Great artwork
• Free spins wins are tripled
• Ways of winning are adjustable

CONS

• Nothing

Superman II: Grab Your Cape, It’s Time to Spin and Save Metropolis

In this slot, we’re heading to Metropolis, the fictional city that Superman needs to clean up. You can see the amazing image of the city in the backdrop. The beautiful skyline is also visible and actually covers a lot of the background of the game. The 5 by 3 playing grid is squeezed right in the middle of the screen, giving you a chance to admire the perfect artwork. 

I haven’t found many slots with as many features as this one. In my experience, you can expect to trigger the Superman Wild feature most frequently. When it's triggered, Superman will fly across the reels, replacing a few symbols with wilds. Remember that the wild card replaces other symbols to form winning combos. 

I noticed that the most lucrative wins are hidden in the free spins bonus. This bonus comes in three different forms. The first is the Phantom Zone, which awards unlimited free spins. The best thing about this feature is that each spin comes with a Phantom Zone that covers a 2 by 2 grid. This works as the wild in the game. You may also get a multiplier (2X or 3X). 

The other free spins bonus I got is the Skyline Fight. With this, you’ll receive 10 free games with a multiplier that goes up to 5X. Watch out for the X-Ray Wild feature as well since it can award you 15 free spins. What disappointed me with these features is that they can’t be retriggered. 

Another feature I found interesting is the Battle for Metropolis. Don’t expect to make big profits with it though. It’s designed as a pick-me mini-game, meaning you’ll get instant prizes. 

To sum up, Superman II offers a comic book-like gambling experience, with all the familiar symbols and cartoon designs. I was highly impressed with the range of features in the game. I could expect a new feature to be triggered every few minutes.

PROS

• Unlimited free spins 
• Pick-me mini-game available 
• Offers jackpots
• Sharp artwork

CONS

• None

Wild Buffalo: Follow the Buffalos to Win Big Jackpots and Multiply Them by up to 10x

Set in the vast prairies, NetGame’s Wild Buffalo gives you a chance to make some serious cash. You have the regular multipliers which go up to 3x and up to 15 free spins, but the highlight here is the jackpot bonus wheel which can go as high as 10x the value of your jackpot. Here’s the rundown before you take on the Buffalo herd head-on! 

The game looks stunning with realistic graphics on symbols, smooth animations all around the reels, and a relaxing background score setting the scene perfectly for some late-night sessions. You get a 5x4 grid with 1024 paylines and medium-high volatility. 

From what I gathered during gameplay, wins were fairly frequent and I was landing matching combinations every 2 to 5 spins. On the other hand, the wins weren’t very profitable most times as wins go as low as 0.05x your bet and I was getting between 0.50x to 2x returns most times. 

Although there were times during the base game when I would make between 5x to 7x returns on a spin, they were quite rare. Even back-to-back wins won’t get you serious profits in the standard reels. 

Fortunately, the Buffalo Fortune Wheel is here to address the relatively low wins during the base game. I was able to get to the round fairly quickly and with my first bonus wheel spin won a mini jackpot and a respin at the bonus wheel. Secondly, I also won a 2x multiplier right after which got me the second biggest win I had all throughout my session. 

On my second spin I won 8 free spins and made even more profits passing the 25x returns mark with ease. In general, I made between 25x to 35x returns with free spins which were the biggest source of big wins for me. 

In short, if big jackpots are your thing, and let’s be honest, who doesn't dream of hitting it big? I would recommend you try out a few spins in Wild Buffalo by NetGame. It is a relatively simple slot title with easy-to-learn features, favorable mechanics, and the possibility for some seriously impressive wins. 

PROS

• Impressive graphics with smooth animations
• 1024 ways to win from the start 
• Up to 15 free spins 
• 3 different jackpots with a chance to 10x them

CONS

• The symbol payouts could have been a little higher

Lucky Larry’s Lobstermania 2 by IGT: Reeling In Riches

Hey there! Let me tell you about Lucky Larry's Lobstermania 2, the super fun slot game by IGT that's been keeping me entertained for hours. First off, the graphics are top-notch – bright, colorful, and filled with cute lobster characters that make the whole game visually appealing.

What I love most about Lucky Larry's Lobstermania 2 is how easy it is to play. The interface is user-friendly, making it perfect for both beginners and experienced players. You can adjust your bet size, spin the reels, and enjoy the game without any hassle. 

Oh, and did I mention the music? The soundtrack is so catchy! It keeps you in the groove as you spin the reels. And the sound effects? They're fantastic, especially when you hit a winning combination.It's like a mini celebration every time!

But I know you are here to learn more about the features and if they are actually any good, so I’ll address that curiosity right away. One of the coolest features is the Buoy Bonus. When you hit three Lobster Mania 2 symbols on a payline, you trigger this bonus round. It takes you to a screen where you get to choose buoys, each hiding awesome prizes. 

You can win Free Spins, Multipliers, or even a chance to pick more buoys for additional rewards. It's like a treasure hunt right in the game! Then there's the Jackpot scatter symbol. Get three of these, and you enter the Jackpot feature where you can win either the Light Trap, Full Trap, or Mother Lode Jackpot. Imagine the excitement of hitting that Mother Lode Jackpot! It's like striking gold!

I also spotted Multipliers. During the Free Spins Bonus, if you get the Lucky Larry symbol, your winnings get multiplied, giving you a chance to win big. And trust me, there’s nothing like seeing your winnings multiply right in front of your eyes! 

So, if all your questions got their answers in this short preview, there is nothing left for me to say except that Lucky Larry's Lobstermania 2 is a thrilling slot game that combines exciting gameplay, amazing graphics, and fantastic bonuses.

Fruit Case: Grab a Freshly Squeezed Lemonade and Reap the Rewards

Craving some sweet fruits? Then here’s a game for you. The highest-paying symbols in the game are all funny-looking fruit faces, and jars with card symbols serve as the lower-paying icons. I found the game design impressive. The game uses clear reels with 3D graphics. It seems to be set in a factory with pipes running through the walls. 

The standout feature of this game is the avalanche. So, how does it work? Whenever you score a winning combination, the matching symbols will disappear from the reels, and new ones will fall to replace them. The cherry on top is that you’ll get higher multipliers with each new win. These multipliers go up to 8X (for the fourth win). Since this feature is available on every spin, it helped me generate significant profits in the game. 

I was also impressed by the Free Falls bonus. You’ll get a total of 10 free falls when the feature is triggered, and these can be retriggered. Remember also that free fall wins get a 3X multiplier. The only issue I noted is that getting this bonus can be quite a challenge. Retriggering it was close to impossible. 

Still, playing this game was quite a breeze. There aren’t many settings to configure. Just choose the bet value and push the spacebar to spin the reels. You can also choose to turn on the auto-spins function for a hands-free playing experience. Don’t forget to indicate when the auto-spins should stop (eg. at a certain loss or win limit). 

To sum up, I found Fruit Case quite pleasant to play. The silly-looking fruit faces are very well drawn, and the bright colors only help to make it more relaxed. I was impressed with the avalanche effect as it makes the game quite profitable. The Free Fall bonus was also lucrative.

PROS

• Has an avalanche function
• Free Falls bonus with 3X multiplier
• Great artwork and game design

CONS

• Nothing

Play N Go’s Agent of Hearts: Meet Mad Hatter, Caterpillar, Dormhouse, and Cheshire Cat!

For sure, one of the most beautiful slots I’ve ever played. Agent of Hearts is not just a slot, it’s a whole puzzle game, and it puts you in the gloomy Tim Burton-ish - Alice in Wonderland atmosphere. I would play this slot at a Halloween party for sure!

The thing is: Agent of Hearts is very lucrative. With just a small bet, you may trigger the Agent bonuses, and the characters come to life on your reels, giving you various prizes with unique animations. The White Bunny may also trigger, and it will activate all the Agents at once. 

As long as symbols fall down and form clusters, you are a winner. And also the Free Spin bonus round: it’s simply more than amazing, a big thumbs-up to the slot’s team who clearly put a lot of effort into this game!

Agent of Hearts Tip to Win

Watch for the random bunny feature! It will trigger the agent bonuses.

CapyPark: Discover What Makes This Slot's Free Spins Round So Rewarding

CapyPark from GameBeat is a pleasant, nicely designed online slot with a relaxing soundtrack and a delightful funfair theme. While it certainly looks appealing, it’s also a lot of fun to play thanks to its special features. 

When playing CapyPark, there was a multiplier feature that would trigger at random every so often. Each time it came into play, the top of the carousel would spin and a multiplier of up to 10x would be applied to all wins on the current spin. This happened several times during my playthrough and helped boost my winnings a bit.

I won most of my money from the free spins round, which I was fortunate enough to play twice. The first time, three scatters landed and I won six free spins. The multiplier feature was active on each spin, with the values increased to a maximum of 100x. I didn’t manage to score any wins with a 100x multiplier, though I still did secure some big payouts. In fact, I ended the round with a win of 116x, which I was very pleased with.

The second time I got to play the free spins round was when four scatters appeared. I had nine free spins and was hoping to earn more than last time. I didn’t, though I still managed to win 50x, which is nothing to complain about. There was the option to buy the free spins round, though I didn’t make use of this since I got to play the feature twice during normal gameplay.

I enjoyed playing CapyPark and was pleasantly surprised by how rewarding the free spins round was. If this slot sounds appealing to you, go ahead and try it out. Hopefully, it will be just as rewarding for you as it was for me.

PROS

• Multiplier on random spins
• Multiplier on every free spin
• Very rewarding free spins round

CONS

• None
