The Vampires II Slot by Endorphina

Three or more scatters do something unusual here: they don't drop you straight into the spins. First you're taken to the Necropolis, a field of headstones, where you dig graves to reveal a set of bonuses. Whatever you uncover stays locked in for the entire run of free games, so this grave-dig decides how the whole round will play before a single reel turns. The base award is 6 free games, and the round can't be retriggered, so the dig is your one shot at stacking advantages.

What you can dig up varies a lot. Sometimes it's extra spins (+1, +2 or +4 on top of the six). Sometimes a Sticky Wild that nails itself to reel 2, 3 or 4 and holds there until the last spin. You might draw one or two Moving Wilds that jump to a fresh random spot every spin, or just a handful of extra wilds scattered in. Two of the more interesting draws change a chosen character: one lets that character land stacked across a reel, the other hands it full wild capacity so it substitutes for everything but the scatter. Plain x1 or x2 multipliers are in the pool too. And there's a daytime catch worth chasing - if you reach the Necropolis while the sun is up (vampires sleep through it), Hot Mode doubles the number of bonuses you draw.

The setting is straight gothic-horror camp, and it knows it. A moonlit blue graveyard with a haunted castle off to the side, bare twisted trees and a starry sky behind the reels, all deep midnight blue with blood-red and silver trim. The cast does the high-paying work: a fanged male Count, a blonde and a brunette female vampire, and a rugged Vampire Hunter in a wide-brimmed hat, backed by a blue blood vial, a red diary pinned with a wooden stake, a crossbow and a pink pistol. The standard Wild stands in for all of them, scatter aside.

The Bonus Pop button to the left of the reels skips the wait, and it goes a step further than most buy features: you don't just purchase the free games, you also pick how many graves to dig at the Necropolis, which directly shapes the bonus haul. Anything Bonus Pop pays out is locked away from the gamble. That gamble is the usual Endorphina card draw - beat the dealer's face-down card to double, joker beats all, up to ten times in a row. Sitting underneath everything are the network Grand, Major and Minor mystery progressives, drawn at random with bet size nudging the odds, the kind of gothic sequel that leans on its bonus draw rather than the base spins to carry it.
