Online slots are all the rage in the world of online casino gaming. No wonder software developers release a ton of new slots with exciting themes and features every month. After much discussion and a few arguments, we finally have our “Best slots from May 2021″ list.

mr macau slot by betsoft

1. Mr. Macau

Mr. Macau is a sublime Betsoft slot with a lot of spark. The theme showcases Mr. Macau a flamboyant casino gambler at the helm of things. Moreover, this charismatic dude showers real money slots players with a slew of goodies!

Now, there’s no official word about the slot’s hit frequency. What’s important is that it comes with an RTP of 97.07%. That’s way above average and the math model packs a punch or two. The volatility is medium and you can win more than 4,000x your bet per spin. You can join the game’s friendly host, Mr. Macau, on the reels from $0.16 and $24.

The visuals are fancy, with plenty of animations to draw you in. The symbols are all about casino accessories such as dice, chips, and Mr. Macau. As far as the symbol values go; Mr. Macau is the second-highest value symbol.

For bonus rounds, there are random features like Stick and Respin and Mr. Macau’s Wild Boost. Once you trigger them they shower you with Sticky Wilds that hang around for a while. In the Free Spins Feature, players can cash in on Sticky and Multiplier Wilds. The latter appears only when four 7s symbols pop on a spin. Guess what? You can play Mr. Macau the slot for real money at any of our legal USA casinos online!


2. Spring Wilds

Spring Wilds is an RTG slot with an Easter theme. It has 5 reels, 3 rows, and 25 paylines, with a big jackpot of 50,000x your stake. You can enjoy it for stakes between $0.25 and $25. When RealTime Gaming released the slot machine; it did not disclose its RTP. If we can go by the studio’s previous releases like Paddy’s Lucky Forest, the RTP should be in the 96% range.

The symbols on the reels are card ranks from 9s to Aces for low pays and animals for high pays. The designs are easy on the eyes and they become animated on winning spins. Even Easter Egg Wilds can appear to help you out with winning combos.

For bonus rounds, you can enjoy the Lucky Streak Re-Spins and Free Spins. The former is all about collecting as many Bonus symbols as you can. The more you get, the better your final payout will be. The latter are free spins which enables you to trigger the Lucky Streak Re-Spins. Needless to say, if you’re into Easter bunnies and stuff; Spring Wilds is the slot to play!


cauldron slot by yggdrasil

3. Cauldron

Cauldron is a Yggdrasil real money slot with 5 reels, 3 rows, and 20 winlines. It’s got a witchy theme, with one big cauldron that occupies the reels set at all times. The production values are suitably decadent. The best part is you can play the slot for cash at our safe casinos online for Australians.

In other words, the slot comes with plenty of animations. Note, you won’t see any card symbols on the reels. Yggdrasil drops plants and all kinds of small monsters symbols that pop as you spin the reels. You can play the slot for as little as $0.10 to $50.

The math model is good too. Furthermore, the RTP of Cauldron is 96.04%. The hit frequency is 20.29%, therefore, winners pitch on every 5th spin. The reward is not too bad either since the maximum earning potential is 2,222x. Keep in mind, that it’s also a high-variance slot online.

The bonus rounds are Free Spins Feature which you can trigger with 3 or more Scatters. It comes with all kinds of symbol transformations. However, there’s an additional free spins feature titled the Super Free Spins. Before you can initiate this free spins feature you need to collect 750 Scatters. The Super Free Spins feature is oodles better because it offers you upgraded symbols for the bigger wins!


hat trick hero slot

4. Hat Trick Hero

Hat Trick Hero is a Betsoft slot with a soccer theme. Besides, it’s not often we see slots with a soccer theme from Betsoft. Suffice to say, this gives us reason to celebrate a bit. No vuvuzelas here, the audio track ropes you in from the first spin.

As a slot with medium volatility; Hat Trick Hero is relatively easy on the pocket. It offers you a jackpot of 1,260x and a hit frequency of 27.37%. The slot opens up seamlessly in Portrait Mode at our fast cash-out mobile casinos. But, Hat Trick Hero drops a few neat treats of its own too. For bonus rounds, it offers Power Shot Wilds and Hat Trick Hero features. The power shot wild serves as the game’s scatter and wild.

There’s more! Keep an eye on the Score Meter, if you fill it. That’s when the magic happens. Before you can do so you need to fill the meter with 15 Power Shot Wilds. We’d like to point it’s not as difficult to fill the meter as you think. In fact, we managed to fill the score meter a few times.


book of 99 slot by relax gaming

5. Book of 99

Book of 99 is a top Relax Gaming slot that comes with a massive selling point. Do you want to know what it is? The online slot boasts an unusually high RTP of 99%. So, the edge to the house is a tiny 1%. The setting occurs in ancient Greece with all manner of mythological creatures on the reels. Moreover, the slot has 5 reels, 3 rows, and 10 paylines. And, you can spin the reels from $0.10 to $100.

The hit frequency is pretty mint too as it stands at 29.83%. Unfortunately, the volatility is well North of high since you’re playing for a jackpot of 12,075x your stake.

The bonus rounds are your typical “Book of” bunch. The Book symbols combine nicely with the Wilds and Scatters. Get 3 and you’ll trigger the Free Spins Feature. We like the free spins feature because it picks a random symbol expanding symbols for you before it starts. Technically speaking, you can catch an expanding symbol that covers an entire reels on any free spin.

The expanding symbols also pay when they’re not on adjacent reels. More importantly, it comes with a Wild Collection system. Interestingly, you can also trigger the Free Spins Feature for every 99 Book symbols you collected. How’s that for an alternative trigger!
