Dark Summoning Slot by Hacksaw Gaming

Super Cascade is the central tumble variant here, and it works differently from most. When a winning combination lands, every instance of that symbol type gets removed from the grid - not just the symbols involved in the win. One match strips an entire symbol out of play and drops a wall of fresh icons. Chains stack up fast.

Wild Multipliers run from 2x to 100x, and when two or more sit in the same winning line, their values add together. A 25x plus a 50x on one payline is 75x, not multiplied. The Order scatter pushes that further: it replaces itself and up to 9 other positions with wilds, some carrying multipliers. One Order mid-cascade turns a chunk of the grid wild in a single step.

For 130x you can buy directly into Trial by Hellfire, or 250x for Rise to Salvation - but both also trigger naturally by collecting 3 Unholy scatters during base play. Which bonus you enter depends on whether an Order symbol is present when the third Unholy lands.

Trial by Hellfire runs 10 free spins. Every winning position gets branded with a Hellfire marker. When an Unholy symbol drops during the bonus, it activates Fires of Hell, converting itself and all marked positions into wilds - some with multipliers up to 100x. Markers then reset, and the buildup starts over. Early spins seed the grid; one well-timed Unholy drop floods it.

Rise to Salvation flips the cascade direction upward. Lost Soul symbols persist and float toward the top row. Global Multiplier souls (2x to 100x) feed a persistent counter above the reels, while Cash Prize souls pay 10x to 666x bet scaled by that counter. Stack a few multiplier souls early, then land a 666x cash prize sitting at 20x global, and you see how the math works. Three consecutive non-winning spins trigger an automatic removal of 3-5 symbols, forcing fresh drops as a safety net.

A hooded skeletal priest and a hulking demon flank the stone tablet grid, lit by hellfire glow creeping along the edges. Low pays are runic symbols carved into dark stone tiles. The premiums - moths, all-seeing pyramids, skulls, ornate crosses - sit against deep blues and burning oranges, the whole scene set inside a torch-lit dungeon that pulses with heat.
