Immortal Desire Slot by Hacksaw Gaming

Two bonus modes that play nothing alike. Blood Moon gives you persistent reels with refreshing multipliers across 10 free spins. Dark Awakening strips away every paying symbol and turns the grid into a pure number-collection game. Same slot, completely different win paths, and the gap between them matters more than usual because the base game leans hard on a single mechanic to produce anything above minimum payouts.

That mechanic is Blood Reels. Any spin can randomly turn one or more reels red, and when it happens, high-pay symbols on those reels become Vampire variants carrying multipliers from 2x to 100x. Multipliers on the same winning combination add together - two Vampire symbols hitting 30x and 50x on a five-of-a-kind of the top symbol (10x base) means an 80x multiplier on that 10x. All five reels can go red on a single spin. Without Blood Reels activating, though, the paytable is flat. Four low symbols all pay identically, and even the best premium only reaches 10x for five across 1,024 ways. Blood Moon at 100x or Dark Awakening at 200x both skip that grind, and a 3x FeatureSpins option bumps trigger odds by 5x if you want to stay in base play but speed things up.

Dark Awakening is the stranger mode. Four scatters trigger it, and the grid fills entirely with blanks - no regular wins happen at all. Instead, Awakened Multiplier symbols land and build reel multipliers displayed above each column. Normal variants add 1x-500x to their own reel. Epic variants add to all five. Multiplying types (x2 to x10) exist in both Normal and Epic forms, scaling totals instead of stacking. Coffin symbols are sticky - they sit on their reel through all 10 spins, then each one reveals a x2 to x10 multiplier applied to that column's accumulated total. Once the last spin resolves, all five reel totals combine and pay out against your bet. It plays more like a bonus-round minigame than anything resembling a slot feature, and the ceiling sits wherever those Epic Multiplying symbols and Coffin reveals land.
