1. Wild Bison Charge: The Best Overall May Slot 

Wild Bison Charge Slot by Pragmatic Play (Desktop View) from SlotsMate on Vimeo.

One look at Pragmatic Play’s brand new upcoming slot release might leave you thinking it's a generic western-themed slot game. 

However, the more we played, the more we realized how wrong we were in that assumption.

Beautiful visuals, crisp animations, engaging music, and a realistic background does justice to the long-overused Grand Canyon Theme. 

Wild Bison Charge Theme 

This upcoming slot game is set in the arid Grand Canyon with rocky cliff formations and you see the Colorado River snaking its way through the rocky canyon. 

For a harsh region like the desert, the animals inhabiting it are just as deadly. 
You find Bison, Mountain Lions, Eagles, and Wolves throughout the slot. These animals are also beautifully animated to pop out with their own cries when you win. 

The music feels like something from a Western cowboy movie and fits seamlessly. All these combined make the theme really shine all throughout your gameplay. 

Wild Bison Charge Game Mechanics and Features

Being a 5x5 win-anywhere slot, the mechanics of Wild Bison are easy to understand for all players. All you need to get are eight matching symbols anywhere in the reels to win. 

The biggest win comes with the Bison, and if you get the symbol in every position in the reel, you get a payout of 250x your original bet. The chances of getting it are slim, though, as we found two or three Bisons were common with each spin. 

The slot has an RTP of 96.03% which is on par with other online slot games and has high volatility. During our testing, we found the win intervals to be average, which was to be expected. 

The betting range is also standard as they range from $0.20 to $100 with a healthy mix of free spins scattered throughout. The max win per line is 12,000x your bet but is equally rare to get. 

The house edge is set at 3.97%, which is also standard with video slots online. Coming to the free spins, scatter symbols are present on the reels, and hitting 3,4 or 5 scatter symbols gets you 9, 12, or 15 free spins. 

You also have the Bonus Buy feature, where you can buy free spins for 100x your bet and increase your RTP to 96.04%. 

Wild Bison Charge Pros:

• Exceptional ambient music and sound effects 
• Beautiful visuals and animations 
• 12,000x maximum win
• Higher RTP results in longer gaming sessions 
• Free spins can be bought 

Wild Bison Charge Cons:

• Unoriginal theme

Wild Bison Charge does justice to its theme with beautiful visuals and animations for the characters as well as the background scenery. 

With customizable betting options suited for beginners and high rollers alike, it has the potential to be a standout slot for the month of May. So what are you waiting for? Get your hands on Wild Bison Charge free slot earlier than everybody else, and practice today! 

2. Dead Man’s Gold: The Best Slot for Bonus Features 

Dead Man’s Gold Slot by ELK Studios Gameplay (Desktop View) from SlotsMate on Vimeo.

Dust off your pirate hats and unsheathe your swords for a brand new adventure in the treacherous seas with ELK Studios' Dead Man’s Gold. 

The pirates have hidden a lot of treasure that is yet to be found, and that’s exactly what you will be doing in this brand-new pirate-themed slot game. 

A chance to 25,000x your bet is a chance worth taking, after all! 

Dead Man’s Gold Theme 

Cannons, pirate symbols, ships from the golden age of sail, all of this and much more awaits you in ELK Studios’ latest entry, Dead Man’s Gold. 

Hanging out in a pirate cove may not be for everyone, but for the daring few who do decide to linger, the potential to win big is definitely there. 

With anchors, stingrays, cannonballs, and the dreaded red Jolly Rogger, the game keeps a mysterious aura around it. Add to that the fantasy music and cloudy waterfall in the background, and you can fully immerse yourself in a treasure hunt, pirate style! 

Dead Man’s Gold Mechanics and Features 

ELK Studios have kept their traditional 6x4 reel system with their new entry, but the bonus features are just as crazy. 

With 262,144 pay ways and a huge 25,000x top win, Dead Man’s Gold is definitely what people looking to win it big would want to play. 

The one problem we had with this slot was the below-average RTP of 94%. Combined with its high volatility, your game balance could quickly go from very low to very high and the other way around. 

The betting range is standard at $0.20 to $100, with 12 bet levels that govern the ultimate winnings. We liked the fact that switching bets was easier and more convenient than the previous entry. 

Starting off, you will have access to 4,096 pay ways, activate a winning combination once, and you get the Avalanche to form. As it triggers, the Avalanche makes the winning icons disappear and adds an additional row of icons that can take your reels from 6x4 to 6x8. 

Coming to other bonus features, Treasure Targets is the first and most frequent one. This feature activates the cannonballs under the matrix that start blasting to reveal hidden Wilds as well as destroy non-winning icons. 

The bottomless chest feature is also an interesting one, as it adds premium symbols, wilds, or cannonballs to the reels. We did enjoy all of these features, but their novelty quickly began to run dry the more we played.

Dead Man’s Gold Pros:

• Huge 25000x maximum jackpot 
• Immense variety of bonus features 
• Multiple pay ways ranging from 4096 to 262,144
• Pleasing visuals, especially on mobile 

Dead Man’s Gold Cons:

• Below-average RTP of 94% 
• High volatility for the small wins 
• X-iter facility hides the super bonus 

If a big win is what you’re after, there are very few slots that will match the massive wins and bonus features in Dead Man’s Gold online slot. Bottomless Chests and Cannons await your arrival, captain! 

3. Purrfect Potions: The Best Slot for Graphics 

Purrfect Potions Slot by Reflex Gaming (Desktop View) from SlotsMate on Vimeo.

Everybody loves wizards and cats, and Reflex Gaming has brought us a culmination of these two elements in the form of Purrfect Potions. 

The pun might not be for everybody, but disregarding that, what you have here is a solid fantasy-themed slot with good RTP and bonus features. 

This mysterious world of magic-wielding cats is filled with potions, spell books, enchantments, and a pleasing art style. 

Purrfect Potions Theme 

Cats dressed as wizards, bottles full of magic potions, witch hats, round orbs of mana, everything magical can be found in Purrfect Potions. 

The cat is mysterious too, with colorful eyes and a purple robe with a magic staff just to add that extra layer of peculiar looks. 

Named Professor Purrfect, it definitely knows something that it's not willing to share so easily. A mist also surrounds these furry wizards, which really sells the magic aspect of the game. 

Purrfect Potions Mechanics and Features 

Reflex Gaming’s upcoming slot relies on the tried and tested 5x3 reel system with 20 paylines. The game has plenty of Wild Bonuses and a multi-level Free Spins feature, with Wild Bonuses working even on free spins.

The game has an RTP of 95.5% which is the highest we have seen so far, and boasts a max win of nearly $2.5 million. 

The very high volatility can be a slight issue for some players though, but during our testing, we saw a fair consistency in winnings which was engaging. 

The betting system is something we liked as it made changing best easier with all of them laid out neatly. 

The minimum bet is $0.20 while the maximum bet is $100, again a standard offering, so no complaints from our side. 

The Purrfect Potions symbol landing on the reels can get you anything from a Wild Magic, where every symbol on a reel turns wild, a Magic Touch which creates 2-8 wild symbols at random, and Mystery Wilds which gets you 2x,3x,5x, or 10x multipliers. 

All in all, Purrfect Potions is a visually appealing slot that anybody can pick up and play with an engaging theme. The game suffers a little from having a limited selection of symbols which is a downside but still manages to be a game you could enjoy for hours with good RTP and bonus features. 

Purrfect Potions Pros:

• Good graphics 
• Background music and sound effects are catchy 
• High RTP for longer sessions 
• Bonus Buy feature is available 
• 20,517x max win is huge 

Purrfect Potions Cons:

• No bonus round 
• Repetitive symbols on the reels 

So what are you waiting for? An adventure in the magical feline world awaits. You don’t want to keep Professor Purrfect waiting! Come try your hand at the Purrfect Potions slot by Reflex Gaming for free. 

4. Euphoria Megaways: The Best Slot for Animations 

Euphoria Megaways Slot by iSoftBet Gameplay (Desktop View) from SlotsMate on Vimeo.

iSoftBet’s Euphoria Megaways takes you out of Earth for a gem-covered galaxy-wide tour where you also get to win money. 

The background of a colorful galaxy and gemstones, along with plenty of additional features, helps this slot strike an adequate balance between visuals and gameplay. 

iSoftBet also put in BTG’s Megaways feature for added returns in the game, making wins more unpredictable and fun. 

Euphoria Megaways Theme 

The theme of Euphoria Megaways is set in a beautiful galaxy that glows pink and tries to visualize the state of euphoria that your mind gets to when you are extremely happy. 

The cluster of stars all around also adds a nice touch to the theme of the game. 

Although gems aren’t the first thing you’d expect in space, they sure will make you happy, so their inclusion is understandable. 

The soundtrack is a similarly high energy if not a little 80’s sci-fi, but it fits well with the theme. 

Euphoria Megaways Mechanics and Features 

Euphoria Megaways may look like a standard slot, but it has 6 reels with 2 to 7 rows. This variation in rows is what decides the pay ways, with 7 opening up 117,649 ways to win! 

The RTP of the game is 96% which is average considering other slots and has high volatility. On our tests, wins were frequent and colorful enough to keep most players engaged. 

You can bet between $0.20 to $20, which would be enough for most people, but some high rollers might come out disappointed with the betting restrictions. 

Landing on symbols pays you anywhere from 0.4 to 1.25x your bet, whereas the gems can pay up to 2 to 50x your bet. The max win is slightly lower at 10.000x but is still respectable. 

Mystery symbols are another good addition, as they can come at any time and transform into a paid symbol. Star symbols, in a similar vein, add multipliers to your wins and can have their values multiplied if you get multiples. 

The many bonus features are tucked away neatly inside the Euphoria Bet option. From the 30x bet Euphoria Spin to the 100x Bonus Buy and finally to the 300x Super Free Spins feature. 

Coming to the free spins in the game, the jig is simple, land 3,4,5 or 6 scatter symbols for 8,10,12, or 14 free spins. If a free spin triggered a red scatter symbol, then you get bumped up to a Super Free Spin! 

Euphoria Megaways is a novel and fun way to reintroduce iSoftBet’s 2020 slot Euphoria but with many more ways to win and a fresh coat of paint. 

Seamless integration with your mobile and easy-to-use Bonus Buy features make Euphoria Megaways a worthy successor to iSoftBet’s previous entry. 

Euphoria Megaways Pros:

• Top-notch graphics and sound quality 
• Bonus Buy feature with options 
• 117,649 mega ways 
•  Frequent free spins and multipliers 

Euphoria Megaways Cons:

• Low max bet of $20 
• Lower max win of 10,000x 
• No progressive prize 

No time to waste, then! The many gems and unknown symbols could hold your next big win. So why not give Euphoria Megaways free slot a try? Maybe you’ll be ecstatic too, or dare we say, euphoric?

5. Dog Squad: The Best Slot for Win Multipliers  

Dog Squad Slot by Booming Games (Desktop View) from SlotsMate on Vimeo.

It’s a dog-eat-dog world out there, and Booming Games are here to remind you of that with their latest game. 

Maybe it's not as ruthless as I may have made it out to be, Dog Squad is all about cool dogs who live in the city and listen to Hip Hop. 

The game gives you a lot of agency on how you wanna use your perks which also adds a small element of strategy that we will discuss later. 

Dog Squad Theme 

The theme of Dog Squad immerses you in the world of Dogs inside a big city. These mean-looking dogs have a lot going for them, with trashcans and waste littering the back alleys. 

Unlike abandoned street dogs in real life, these dogs have taken to emulating 90s rappers with gold chains and west coast tattoos. 

Perhaps not the tattoos, but you have everything else, cigars, wayfarer sunglasses, and much more! 

The music fits them, too, with an old-school rap theme playing in the background that would make Snoop Dogg happy. 

Dog Squad Mechanics and Features 

Starting off in this 5x3 slot may be easy, but the more you play, the more you realize the number of choices and options you have with Dog Squad. 

The game has an RTP of 95.6% which is slightly below average with high volatility. The maximum win of 2000x or $150,000 is a decent catch if you can get it. 

Betting starts from $0.10 and can go as high as $75, giving every type of player a fair share of options to choose from. There are a total of 22 stake levels, so playing around with your bet amount is encouraged. 

Common card symbols can pay you between 3x and 4x your bet, but the big wins come with the dogs themselves, with payouts ranging from 2x to 20x your original bet. 

The game’s bonus features are exciting, too, and the most frequent one you’ll get is the Random Win Multiplier. The multiplier kicks off randomly at a spin and awards you either 2x, 4x, 6x, 8x, or 10x on top of your bet. 

Gain three scatters, and you land the Unlimited Free Spins feature, where you’ll start off with a 2x bet. You also get assigned a random multiplier between 2x and 10x, with each win increasing the number and each loss decreasing it. 

Dog Squad Pros:

• Unique theme 
• Catchy music that is also cool 
• Interesting bonus features 

Dog Squad Cons:

• Lack of features 
• No bonus buy option 

Wouldn’t you want to join in with these dogs and experience life through their eyes for a while? Be their companion in the busy city and see what rewards does the Dog Squad online slot have in store for you!
