Dark Summoning Features

There might only be 40 pay lines in play but there are enough modifiers to keep the action feeling a lot fresher than the two main characters. The symbols are made up of five royals and six pictures with one of those being a Wild symbol. Five Wilds get you a 30x win. They will also substitute for all other regular symbols. 

There are a few other symbols to watch out for and all of these have an unearthly ability to improve your wins and trigger bonuses. Not only are winning symbols removed after a win is recorded, but any other instances of that symbol will disappear as well. This allows new ones to drop into place and potentially create another win. 

The blue cross is known as the Order Scatter symbol and this can land randomly at any point. The purpose of the Order Scatter symbol is to replace itself and up to nine others with Wild symbols that might contain a Multiplier.

Landing free spins

The red crosses are known as Unholy symbols and these can trigger 10 free spins if three of them land together. Alternatively, they can appear on different spins as long as all three arrive within a winning sequence of spins. This first Bonus game goes by the name of Trial by Hellfire and each winning position is marked with Hellfire throughout the game. 

An Unholy symbol will activate the Fires of Hell sequence and this means that the Unholy symbol and those marked with Hellfire are replaced by Wild symbols. Again, these can also bring multipliers. 

The second Bonus game is Rise to Salvation. Three Unholy symbols collected during the Base game and an Order symbol will offer you 10 free spins with symbols now cascading upwards. The main attraction is the Lost Soul symbols, which can come as Multipliers or cash amounts. They ascend the reels as they fill empty spaces during a winning sequence and the result is applied to your total when they reach the top of the reels. It could be an instant cash award or a Multiplier figure added to your Multiplier Meter.

Will Of The Order

When the Order symbol appears it will replace itself and up to 9 other symbols with Wild symbols that could also contain Multipliers.

Dark Summoning - Trial By Hellfire

Land 3 Unholy Scatters at once or collect them during a winning sequence to trigger 10 free spins. Unholy Scatters will start the Fires of Hell Sequence if they land during your free spins and this means extra Wilds might be turning up.

Rise To Salvation

Collect 3 Unholy symbols and an Order symbol to unleash 10 free spins with symbols now moving upwards. Lost Soul symbols land to offer Multipliers to your Global Multiplier and cash amounts.

Dark Summoning Review

You might want to avoid playing Dark Summoning late at night as not only is this the wrong time to be enjoying slots but it could also make your soul scream! Everything about this hellish production is top class and you might find it hard to put down.


To the side of the fiery-backed reels, I presume Satan and the Grim Reaper are awaiting your instructions. Each one of them is in charge of a different Free Spins Bonus and they aren't afraid to tease you with a little electrical show as you come close to triggering their respective features. You couldn't ask for more in a visual sense and the audio is more than up to the task as well. I'm not sure about the old-school sound effects as you land a win, but that's just my personal preference.


The Order Scatter symbol with its plethora of Wilds and the Super Cascade both make the base game a fun and potentially profitable segment and this only gets better as you enter into the dark world of Rise to Salvation and Trial By Hellfire. The former will probably produce the best results but they are both incredibly entertaining to watch. The Fires of Hell sequence is a kind of unstated extra that simply pops up during the bonus game and creates Wild action beyond your darkest dreams.

Win Potential

A 10,666x top win can't be a coincidence and is yet another indicator of how much effort and thought has gone into this creation. The volatility isn't too bad either for those who are looking to see reasonably regular wins with its medium-high volatility setting. The RTP will vary at times, depending on your access to the Bonus Buy option, but the overall figure stands at 96.36%.

My Verdict

Hacksaw Gaming very rarely let me down with their approach to intricate yet somehow simple mechanics that may take a moment or two to figure out but once you're in the zone, it is a hell of a lot of fun. Dark Summoning should be the first slot on your list today!
