If you're drawn to the darker themes of slot games, this title might be one for you. The two characters of this game - the Grim Reaper and Satan - are the somewhat scary faces of the game. The Reaper oversees the mystical blue realm, and Satan presides over a fiery red inferno called… Hell. The 2 bonus rounds transport you to both worlds.

During the base game, light rock music sets the tone, but when the Trial By Hellfire Bonus Feature activates, the pace shifts dramatically to intense metal. The music is almost otherworldly during the Rise to Salvation Bonus round.

Creepy sound effects, including gongs, Satan's laughter, howling winds, and the screams of lost souls. The game's grid is framed by an ancient stone door, with glimpses of a furnace in the background as the symbols cascade from above. The symbols feature eerie designs, with the highest value being Baphomet, which is a symbol of the devil.

Here’s a rundown of all of the grid’s symbols and their values:

• Baphomat: 3 = 1.00, 4 = 2.00, 5 = 10.00 x the bet
• Raven & Eye of Providence: 3 = 0.80, 4 = 1.50 and 5 = 5.00 x the bet
• Fly & Scissors: 3 = 0.50, 4 = 1.00 and 5 = 2.50 x the bet
• K, J, Q, K & A: 3 = 0.20, 4 = 0.50 and 5 = 1.00 x the bet
• Wild: substitutes for all other symbols

Dark Summoning Mobile

The Dark Summoning mobile slot uses the latest HTML5 technology, which means that you can be assured of an enjoyable mobile gaming experience whether you're using Android or iOS. The game also works well on tablets and desktops, the recommended ratio for desktop browsers is 16:9.

There are 6 bonus features to play with in the Dark Summoning slot game:

Super Cascade

When a winning combo lands, it’s removed from the grid, and new symbols cascade in from above to replace them. This repeats, giving more potential wins until there are no more winning combos.

Trial By Hellfire Free Spins 

Landing 3 Unholy Symbols during the base game triggers 10 free spins in this bonus round. During the bonus, all winning positions are marked by Hellfire. When an Unholy Symbol lands, it activates the Fires of Hell feature. During this feature the Unholy Symbol and all symbols on positions marked by Hellfire are replaced with Wild symbols. Some of these Wilds have multipliers and some don’t, all Hellfire is then removed.

Rise To Salvation Free Spins  

Landing 3 Unholy Symbols during the base game triggers this round, but you also need an Order symbol to be present when the third Unholy symbol is collected. You trigger 10 free spins during this bonus. During the bonus, the symbol drop and the cascade direction is reversed so that symbols move upwards instead of downwards. 

Also, there are special Lost Soul Symbols, and when one lands, it stays on the reels until the end of the free spins or until it Ascends. Lost Souls move upward together and add multipliers up to 100x to the global multiplier. They move with other cascading symbols to fill the empty spaces left behind by wins that have been removed. 

The Lost Soul Symbols come in two variants: a Global Multiplier Lost Soul and a Cash Prize Lost Soul. When they Ascend, these Souls either add value to the Global Multiplier, which is above the reels, or they can award a cash prize. A cash prize is between 10 and 666 x the bet.

Wild Multipliers

There are two Wild symbols, a blue wild and a red wild. The blue wild appears in the base game and in the Rise to Salvation bonus feature. The red wild appears in the Trial by Hellfire bonus feature. 

A Wild symbol can have one of the following multiplier values: 2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 50x, 100x. Wilds don’t have multipliers in the Rise to Salvation bonus.

Will of the Order

When an Order Scatter symbol lands, it replaces itself and between 1 to 9 other symbols with wilds. These wilds might or might not have multipliers. If more than 1 Order symbol lands at the same time, the Will of the Order is triggered once for each Order symbol.

Bonus Buy

If you're outside of the UK you can make use of the Bonus Buy feature where you can buy the following features:

• BonusHunt Feature Spins / Each spin is 5 times more likely to trigger one of the bonus games / Cost: 3x the bet 
• Trial by Hellfire bonus / Activate the Trial by Hellfire bonus feature / Cost: 130x the bet 
• Rise to Salvation bonus / Activate the Rise to Salvation bonus feature / Cost: 250x the bet

It looks like all hell is about to break loose in this immersive game! The terrifying-looking characters are striking and well-animated and there’s plenty of dynamic movement on the grid. The differentiation of the red and blue symbols, worlds, and characters looks fantastic, making the game easier to follow. 

This classic Hacksaw feature effectively splits the game into two opposing teams. Other Hacksaw games like this are Beam Boys and Slayers Inc. Leading on from that nicely - the Wild Multipliers were a highlight - having the 2 colours of blue and red wilds worked well. And the fact they go up to 100x is good going. 

There are some nice touches such as the cascade direction reversing during the Rise To Salvation Bonus meaning that symbols move upwards instead of downwards and the lost souls ascend. During this round the Reaper comes into his own, and the reference to the shadowy realm makes a whole heap of sense as you can see a blue tunnel of light connecting the two worlds.

With an RTP of 96.36%, this game is Hacksaw’s joint 7th best in terms of return, and it also ranks as their 7th best for maximum win potential at a solid 10,666x your bet. If you want to dive deeper into this fantastic studio, check out OLBG’s guide to the best Hacksaw Gaming slots.

This game scores a 4.5 out of 5 for its sinister gameplay and entertaining bonus features.
