X-Demon Slot Overview

Demons are the currency here, and the whole point of the game is turning them into wilds. A narrow strip sits above the reels, outside the paylines, and it holds one thing only: the Wild Attack symbol. Land it with a demon head underneath and that demon converts, then the spin pays.

Underneath that idea is an ordinary machine. Five reels, four rows, 20 fixed lines, wins reading left to right from reel one. No tumbles, no ways count, no multiplier ladder anywhere. Evoplay kept the base game deliberately quiet so the attack row does all the talking, and that works better than it sounds on paper.

The numbers land mid-range across the board: 96.07% back, a hit on roughly 28% of spins, and 2,560x at the very top. That ceiling is the weak spot.

Theme & Design

Two winged stone guardians in cracked armour stand either side of the reels, swords planted point-down, wings spread wide enough to fill most of the frame. Cyan flame burns in stone bowls at their feet. Behind them sits a washed-out pine forest and the ruin of a carved arch, all rendered in the same pale mint green, which is where the art gives some ground. The entire picture is one hue.

The symbols do better. Demon heads sit inside teardrop shields in red, blue, purple and green, every one of them snarling with a mouthful of teeth, and the reel area glows a deep bottle green behind them so they stay readable. The attack strip above is drawn as five carved brown plaques, and the Wild Attack itself is a gold winged W that drops a bolt of light down the reel. Low pays are faceted gem card suits, the usual shortcut. It's dark fantasy dressing that looks good and that nobody will remember a week later.

Features & How They Work

The Attack Row

The extra row above the grid has five slots, one per reel, and it never pays a thing by itself. A Wild Attack landing there turns the demon directly below it into a wild, and only then does the game work out the wins. Gems are immune. An attack that drops over a card suit is simply wasted, which happens plenty given the low symbols outnumber the demons on the strips.

Free Spins

Three, four or five Bonus shields anywhere on the grid award 8, 10 or 12 free spins. The shields appear in the main game only, so there is no retrigger route through scatters once the round starts. Eight spins is the outcome most of the time, and eight is not much runway for what the round is trying to do.

Demon Collection and Golden Wilds

Each of the six demons carries its own meter during free spins, counting down how many more of that demon still need converting. Every Wild Attack that catches one knocks its meter down a step. Complete a meter and that demon turns gold, awards 2 extra free spins, and then stays on the reels as a permanent Golden Wild for the rest of the round. Two or three finished meters change the round completely, because those wilds keep paying on every spin that follows without needing another attack.

No Buy Button in This Edition

This version has no bonus buy at all. Evoplay split it off into X-Demon Bonus Buy, which sells the identical round at 30x, 52x or 86x the total bet for 8, 10 or 12 spins. Same game otherwise, right down to the art.

How X-Demon Plays

The rhythm settles quickly: eyes up, not down. Gem lines drip in often enough at a 28% hit rate, but they pay in fractions, so the base game mostly funds itself while attention stays on the strip above the reels. When two attacks drop at once the grid finally does something.

Free spins are where the design shows its hand and also where it frustrates. The first Golden Wild usually arrives late, and by then there might be two spins left to use it (the meters are on display the whole time, so you know exactly how close you got). Rounds that snowball are the ones where conversions clump early. The gap between a dead bonus and a live one is wide, and that is what medium-high volatility feels like in practice: not brutal, just streaky.

The collection idea probably deserves a longer round than it gets.

Pros & Cons

Pros

  • The attack row gives the base game something to watch instead of flat dead spins
  • Golden Wilds stay for the rest of the round, so a strong bonus compounds on itself
  • Simple 20-line structure with one rule to learn
  • Stakes start at 0.10 a spin

Cons

  • 2,560x ceiling is low for a 2023 release
  • Six collection meters against an eight-spin round is a bad ratio
  • Wild Attacks landing over gem symbols do nothing at all
  • Attractive art that drowns in a single shade of green

Is X-Demon Worth Playing?

5/10

One good idea, executed politely. The attack row fixes the deadest part of a 20-line slot, and the meters give the bonus a shape a player can track rather than just spins to count down. Both do their job.

Scale is what holds it back. The round is short, the top prize is small by current standards, and there is no multiplier anywhere to bend the math upward, so even a strong free spins run tends to finish in the low hundreds of x. It plays well. It just doesn't play big. The collection layer is the part worth loading it up for.

Frequently Asked Questions

What is the maximum win in X-Demon?

2,560x the total bet. Reaching anywhere near it needs several Golden Wilds active at the same time during free spins, which is a rare shape for an eight-spin round.

How do you trigger the free spins in X-Demon?

Land 3, 4 or 5 Bonus shields anywhere in the main game for 8, 10 or 12 free spins. Shields do not appear during the round, so extra spins come only from completed demon collections, which pay 2 each.

What are the RTP and volatility of X-Demon?

96.07% RTP with medium-high volatility. Hit frequency runs around 28%, so something lands on roughly one spin in four, usually a small gem line.

Does X-Demon have a bonus buy?

Not this version. Evoplay sells the buy separately as X-Demon Bonus Buy, priced at 30x, 52x and 86x the total bet for 8, 10 and 12 free spins.

How does the Wild Attack feature work?

Wild Attack symbols land only on the extra row above the grid, which is not part of the 20 paylines. When one appears with a demon symbol directly beneath it, that demon becomes a wild before wins are calculated. Low-paying gem symbols are never converted.

Who is allowed to play X-Demon?

Players aged 18 or over, or the legal minimum age where you live. The demo runs on play money with no real stakes. If you move to real money, set a loss limit first and treat it as entertainment spending.
