Slots Nutter

May 13, 2021

Every month is like Christmas when it comes to the world of online video slots, every month sees the release of new and exciting games for us to play and win with. May is no different, there is a plethora of new games that have already been released or still need to be released.

We understand that your time is valuable so we’ve condensed this month’s releases down to a strong seven, the best that May has to offer. Look out for these titles the next time you log into your favourite online casino and find out for yourself why they made our list.

Our picks are in no particular order, each person has their own tastes, we’re just including the slots that stand out to us this month.

Book Of 99

We’re starting this list of strong, a solid 99% strong. Book Of 99, developed by Relax Gaming, makes this list because of its incredible 99% RTP. It’s not often that we see the release of a title with such a high RTP percentage but when we do we need to make a point of it.

Book Of 99 is a 5-reel, 3-row video slot title that sees players collecting Wilds in order to advance their ancient Greek voyage across the Aegean Sea. What lies at the end of the journey you might be asking, bonus spins of course!

Legend Of Athena

Another ancient Greek slot back to back, this time brought to you by Red TIger Gaming. If you’ve ever played anything from Red Tiger you know why this slot is making the list, the sheer quality of the games they provide is almost unmatched.

Legend Of Athena has players attempting to prove themselves to the goddess of wisdom and warfare with this 5-reel, 3-row video slot game. The 95.75% RTP aid players on their quest and 10 fixed paylines makes sure that their efforts don’t go unrewarded. The Battle Spins are the main reason this title makes the list. Battle Spins are this game’s bonus spins that come with a nice multiplier.

If you’re a fan of the Swedish heavy metal band then you already know why this slot has made the list. For those that are unaware, developers Play’n GO have taken a look at the album covers of the band and turned them into a fantastic cascading video slot game.

The game has worlds that apply special and unique features when triggered based off of songs that the band has produced. What’s even better is that while you play the game HammerFall you get to listen to those songs. Wins are determined by clusters of symbols and the RTP sits at around 96.20%.

HammerFall is available now!

Vault Cracker

The second entry on this list by Red Tiger Gaming is the dastardly and somewhat incompetent Vault Cracker. You’ll need to throw on your best disguise for this one as you’ll be breaking into vaults and getting away with cash and jewels.

You’ll need the help of the Safe Cracking Artist and the Hold-Up Artist in order to get anywhere and trust us when we say you’ll notice when they appear. This video slot game has a fairly decent 95.66% RTP with 10 fixed paylines that will help you get away with the big diamond prize.

3 Clown Monty

Play’n GO is making its second appearance on this list and for good reason, provided you’re a fan of non-traditional clowns and circus acts. That’s right, 3 Clown Monty is an interesting take on the usually joyful circus going experience. With clowns that look like mafia bosses and cigar smoking gorillas you know you’re in for a wild ride.

The game has a RTP of 96.23% with 10 fixed paylines. You might just get lucky and trigger the Multiplier Meter and score an added bonus on your winnings or activate some bonus spins by landing three Scatters at once.

3 Clown Monty will be available on 13 / 05 / 2021.

Scroll Of Dead

It seems as though the Wilde family as well as Play’n GO can’t get enough of ancient Egypt, and that’s completely understandable. Ancient Egypt is home to some of the most fascinating and curious mysteries ever, so of course Cat Wilde has decided to venture into whatever pyramid she could find to dig up some lost treasures.

Scroll Of Dead will help players navigate any dangerous traps that the pharos of old set with a 96.28% RTP rate as well as a solid 10 paylines. Spin all 6 of the reels to find out what exciting fortunes your future holds.

Scroll Of Dead will be available on 20 / 05 / 2021.

Asgard Warriors

If ancient Egypt isn’t your thing or you simply want to take a break from the heat, let 1×2 Gaming take you back to the frozen lands of old Norse myth. Asgard Warriors will have players do battle with some intimidating looking vikings, but if you’re able to hold your ground you could walk away with some serious wins.

The game has a 94.96% RTP rate coupled with chances to earn up to 16 bonus spins at a time. Use these, as well as your own strategy, to your advantage and you’ll be one of the warriors looking for their next adventure!

Asgard Warriors will be available on 19 / 05 / 2021.
