X-Demon Bonus Buy Slot Review

Demon heads rattle a stone gate in a fog-green pine forest, and the whole game turns on a row of cells that pays nothing. Wild Attack symbols land only up there, above the five reels, outside all 20 lines. Catch a demon directly underneath one and it burns into a Wild.

The base game is that and nothing else. No tumbles, no multiplier ladder, no clever bet mechanic, just 5x4 and the occasional bolt from the ceiling. Free spins turn it into a different game entirely, which is exactly why this edition exists: you can skip straight there.

Three prices, 30x the bet for 8 spins, 52x for 10, 86x for 12. The original X-Demon has no buy button at all, so this is the same slot with a shop bolted onto the left rail.

Evoplay went with fog. Everything sits in the same washed green: pines behind, a cracked stone arch overhead with moss on it, and two winged statues in plate armour flanking the reels, swords planted point-down, blue flame burning in stone bowls at their feet. Runes run down the pillars either side of the green felt reel area.

The demons are glossy teardrop medallions in red, purple, green, blue and a sickly teal, every one of them snarling with too many teeth. They are the best art here and they hold up at small sizes. The low symbols are card suits cut as gems, a blue club, a pink heart, a purple diamond, and they look pulled from a completely different slot. Sound is quiet forest ambience with a sharp crack when a Wild Attack fires, which is the only moment the audio does any work.

The base game is a slog, honestly. Hits arrive around 28% of spins and most of them are gems worth a fraction of the stake, so the balance drifts down in small steps while the top row stays empty. When a Wild Attack does drop, more often than not it is hovering over a card suit and does nothing at all, which is a particular kind of annoying to watch. The good spins announce themselves early: two attacks, two demons underneath, and a full line pays before the reels have settled.

Free spins move at a completely different speed. Eight spins is short, and the round gets spent reading counters rather than the reels, because the win amounts stop mattering next to whether the red demon needs one more hit or three. Finish one early and the round breathes, since those +2 spins buy time to chase a second. Come up one short on two separate demons and it ends flat, which happens more often than the good version does. That gap is what the buy price is really covering, and the 30x tier is probably the one worth taking.

A tidy, slightly old-fashioned line slot with one good idea in it. The collection meters give the bonus a structure most 20-line games do not bother with, and the Golden Wild payoff is satisfying in a way the base game never manages. Everything around that idea is ordinary: card-suit lows, no base-game multipliers, a ceiling that will not excite anyone.

Where it lands depends on the buy. The 30x tier is priced sensibly and hands back marginally more than grinding the reels for a trigger, so that is how most people will play it, while the two dearer tiers make less sense the closer you look. Strip the shop away and there is not much here but waiting. Evoplay's art carries more of this game than the math does, and it is good enough to.
