The Crypt Slot by Nolimit City

The signature mechanic sits inside Resurrection Spins. Every fourth winning cascade in the bonus turns one of the five dead rock legends into a permanent Wild for the rest of the round and adds +2 spins. That's the engine. Elvis, John Lennon, Jimi Hendrix, Kurt Cobain, Amy Winehouse, Lemmy - the lineup pulls icons of the 27 Club and stitches them as zombie portraits onto a 6x4 cascading grid where every win explodes the symbols off the reels so new ones can fall in. One catch worth knowing: wins on only the highest-paying symbol don't count toward the Wild conversion. They feed a separate symbol-specific multiplier that climbs +1 every time that same icon hits, and it sticks for the entire bonus.

The xWays mechanic does the heavy lifting on the math. xWays reveals as a chained-up coffin marked with an X, lands on any reel, and contains 2 or 3 of the same paying symbol stacked inside. Each one stretches its reel up to six positions tall. Multiple can land per spin. When all six reels expand fully the ways count jumps from the base 4,096 to 46,656, which is the cleanest 4^6 -> 6^6 expansion in the studio's catalogue. xNudge Wild rides on reels 2 through 5 - a hooded Grim Reaper with glowing green eyes that drops to the bottom of its reel, adds +1 to the win multiplier per step it falls, then expands to cover the whole reel. Consecutive xNudge multipliers add together (x3 plus x1 makes x4, not x3), and with xWays expanding the reel underneath the ceiling sits at x6. In Resurrection Spins at least one xWays is guaranteed on every initial cascade, which is why the route to the 27,000x cap runs through extending the bonus rather than hitting one giant base spin.

The xBet booster is unusually priced. +200% bet, so every spin costs 3x your normal stake, but the trade is a 5x increase in Resurrection Spins trigger odds and a return penalty of only -2% on the math. Most expanding-reel ante options in the studio's portfolio sit at -6%, so this one is mathematically softer than the menu suggests. The buy panel runs 100x for 10 Resurrection Spins (the 3-Scatter trigger), 200x for 13 spins, 500x for 16, and a 225x Lucky Draw with three tiered odds. Visually the reels sit behind wrought-iron thorn edging against a gothic cemetery: tombstones along the horizon, bats over a toxic-green Crypt logo, a half-ruined castle silhouette in the back, low cards carved into stone. Closer in tone to Dead, Dead or Deader than the studio's Wild West catalogue, with the music-graveyard angle as its own twist.
