As we start to enter the latter stages of summer, the entertainment keeps coming in from the industry’s best slot game providers. This month, titles with several themes have rolled out to the market – meaning you’ll find something regardless of your desires. 

As usual, we’ve put together the best 10 online slots produced over August 2021. You’ll find several online casinos that have integrated these titles, with some even including unmissable bonuses. 

And without further ado, here’s the complete list. 

Game of Thrones Power Stacks

Game of Thrones was one of the most successful TV series of all time, with millions of fans worldwide. And now, online casino players can get another taste with this exciting release from Microgaming. 

Game of Thrones Power Stacks allows you to win a maximum of 25,000 times your stake, with 40 different ways to win. You’ll also find several bonus features, ranging from four fixed jackpots to free spins. 

This slot features five reels and four paylines. You can play Game of Thrones Power Stacks on desktop, mobile and tablet. 

Raptor Doublemax

Yggdrasil Gaming has been busy with its slot releases over 2021 so far, and the company certainly didn’t rest on its laurels in August. Raptor Doblemax was one of its releases, featuring a dinosaur-styled theme to transport you back in time.

Raptor Doublemax has a high level of volatility that will keep you entertained for a while. You can also enjoy several bonus features, including free spins and multipliers. Moreover, you can win up to 20,000 times your stake. 

When playing the slot, you’ll have five reels and three rows to win along. Besides unlocking in-game bonuses, you can also buy some of these. 

Agent of Hearts

Like Yggdrasil, Play’n GO hasn’t slacked so far this year. In August, it’s continuing its momentum with Agent of Hearts – a title that will likely remind you of the classic novel Alice in Wonderland. 

Agent of Hearts offers you the chance to win up to 5,262 times your stake and no fewer than 20 different ways to win. In terms of bonuses, you’ll find a selection of wild symbols – plus free spins. 

Agent of Hearts features a slightly larger interface than some of the other slots on this list, with seven rows and the same number of reels. Volatility is high, and you’ll find the game on several online casino sites. 

Jambo Cash

Jambo Cash was released by Yggdrasil Gaming and will transport you into the middle of the African savannah. Featuring beautiful animated imagery, you could win up to 12,056 times your stake. 

This slot offers 4,096 ways to win and has various bonus features, including free spins and wild symbols offering a higher payout. 

Jambo Cash uses six reels and four rows, with high volatility and an above-average maximum return to player (RTP) rate. 

Hugo Carts

Hugo Carts is another of Play’n GO’s exciting slot games released before the end of summer. If you get lucky, you could win up to 25,000 times your maximum stake – while the game also gives you 1,024 ways to win on each spin. 

This slot offers a couple of bonus features worth checking out. You can unlock three different re-spin features, in addition to between seven and 11 free spins – depending on how many scatter symbols you match. 

The Hugo Carts interface features five reels and four rows, with a slightly-higher-than average RTP. Volatility is also higher than usual. 

Africa X Up

Another Microgaming release to make this list, Africa X Up is colourful, vibrant, and fast-paced. When you hit the biggest prize, you’ll win up to 30,000 times your stake. Throughout your time playing, you’ll also have 243 different ways to win. 

Africa X Up offers three bonus features, including a free spins feature where your multiplier increases in value. You can also receive a token by triggering the X Up feature, which you can then use to increase your multiplier. 

Besides the free spins, you can also buy multipliers. The game has five reels and three rows. 

Amazing Link: Apollo

Microgaming’s Amazing Link: Apollo release title will take you back in time to Ancient Greece with superb in-game design and the chance to win 5,000 times your stake. But that’s not all – you could win in no fewer than 20 different ways. 

Amazing Link: Apollo features four fixed jackpots, in addition to free spins and wild symbols that give you a higher payout whenever you see them. 

This slot has three rows, each consisting of five reels. The maximum RTP is higher than the industry average, with volatility lower than some of the titles in this article – but still reasonably high. 


A simple title and a slot that will keep you on the edge of your seat – if not for its horror theme – is this slot developed by Nolimit City. As long as you don’t run away in fear, you could win up to 66,666 times your stake, and there are several ways to win while playing in-game too. 

Mental offers several bonus features, including a wide variety of free spins and multipliers that will significantly increase your winning potential. 

When playing this game, don’t expect a light-hearted experience. Everything, from the imagery to its soundtrack, will fill you with the jitters. As for the interface, you’ll find five reels and incredibly high volatility. 

Fruit Party 2

If Mental is far too heavy for your liking, Fruit Party 2 is a little less extreme. Developed by Pragmatic Play, this slot offers the chance to win 5,000 times your stake and high levels of volatility. 

When playing Fruit Party 2, you can unlock a broad range of bonus features. The random wild multiplier will increase your winning potential, while you can also unlock anywhere between 10 and 25 free spins – depending on how many scatters you get. 

The Fruit Party 2 interface features fruits that look so good you could almost reach out and bite them from your screen. In terms of reels, this is a 7×7 slot.   

Cabin Crashers

Moving back towards the horror theme to finish off our top 10 August 2021 slots list is Cabin Crashers. This Quickspin release features a zombie theme – though you could argue that it’s light-hearted – and the chance to win 22,144 times your stake if you get lucky. 

Cabin Crashers has two bonus features. You could unlock several free spins, while the game also has a multiplier wilds feature for you to take advantage of. 

The game’s interface is pretty simple, with three rows – each of which has five reels. You can play the game across desktop and mobile, and the game has 20 different ways to win.
