Dark Summoning review

Theme and Style

Dark Summoning has a moody supernatural theme.

Players will enter a mysterious realm and meet ghoulish beings. If players want to survive until morning, they will need to face their fears and decipher cryptic symbols.

Those who are curious about the occult may especially appreciate this slot.

Graphics, Sounds and Animations

The soundtrack of Dark Summoning has an intense heavy metal feel. This helps to establish a dramatic atmosphere that aligns with the esoteric theme.

The reels are built from grey stones with hot embers gleaming behind the symbols. On one side of the reels, players will see a hooded figure with a skull for a face. He clasps his hands together and looks out at players with an unsettling intent.

On the other side of the reels, players will meet a demon-like being with horns and pock-marked skin. His aggressive stance and scowling face make it clear that he is not a kindly creature.

A variety of enigmatic symbols can be found on the reels including insects, birds, bones, and goats with red, glowing eyes. Lower-paying symbols consist of minimalist designs that bring to mind ancient runes.

Overall, the animation and soundtrack of Dark Summoning create a spooky world of dark magic.


Dark Summoning is a five-reel, six-row slot, with 24 win lines.

If players wish, they can buy directly into the Bonus by selecting Buy Bonus.

The Super Cascade feature means that whenever a win occurs, all the symbols of the winning type are taken off the reels. This allows new symbols to fall in from above. The Cascades continue until no more winning combinations are possible.

The maximum win for this slot is 10,666x of the player’s total bet.

Wilds, Bonuses and Free Spins

The Wild symbol substitutes for all paying symbols. During the base game, Blue Wilds appear while Red Wilds appear during the Rise to Salvation Bonus and the Trial by Hellfire Bonus.

Wilds may have an associated multiplier between 2x and 100x. However, Wilds do not have associated multipliers during the Rise to Salvation Bonus.

The Order Scatter symbol has the special ability to replace itself along with 1-9 other symbols with Wild symbols. These Wilds may appear with or without multipliers. When multiple Order Scatters land, this feature can be triggered more than once.

Unholy Scatter symbols that form part of a winning combination are gathered in the top right corner of the reels. They are saved for the duration of the round. When 3 Unholy Scatters land at the same time, they are automatically collected, even if they are not part of a winning combination.

Accumulating at least 3 Unholy Scatters during a single round triggers the Trial by Hellfire Bonus. Throughout this feature, all winning positions are identified with Hellfire. If an Unholy Scatter lands, the Fires of Hell sequence will begin, replacing all the Hellfires and the Unholy Scatter with Wilds.

If players collect 3 Unholy Scatters during a single round, and an Order symbol is present during the final collection, the Rise to Salvation Bonus begins.

Gameplay video

Throughout the Rise to Salvation Bonus, the symbols rise onto the reels from below and Cascades also move upwards. Lost Soul symbols are present during this feature. These symbols remain persistent on the reels until Cascades move them to the topmost position on the reel. This is when the Lost Soul Ascends.

Global Multiplier Lost Souls contribute a global multiplier when they ascend. Meanwhile, Cash Prize Lost Souls awards a prize between 10x and 666x when they ascend.
