Return of the Dead Slot by Pragmatic Play

Reel Kingdom built this one on the Book of Dead blueprint. One symbol does double duty as both wild and scatter - the golden Book of the Dead substitutes for everything on the reels, and three or more of them trigger 10 free spins. That's the entire feature set. No hold-and-win side game, no buy bonus shortcut, no ante bet toggle. Just the book and the expanding symbol round.

Before free spins start, a random symbol gets chosen as the special expanding symbol. After each spin pays out normally, that chosen symbol stretches to fill all three rows on every reel where it appears. The key detail: these expanded symbols pay even when they're not on adjacent reels. So if the explorer gets picked and lands on reels 1, 3, and 5 after expansion, that still counts as three of a kind. Three more books during the round add another 10 spins with the same expanding symbol, and there's no cap on retriggers.

Warm golds and burnt oranges dominate the Egyptian setting - pyramids silhouetted against a dramatic sunset, ornate hieroglyphic columns bordering the grid, stone reliefs along the bottom. The explorer character sits at the top of the paytable alongside a blue Horus figure, two pharaoh masks, and jeweled scarabs. Card values from 10 through Ace fill the low end in metallic tones etched into dark stone.

The top-paying explorer symbol and the Book itself share identical values - 500x per line for five of a kind. With 10 lines active and the expanding mechanic ignoring adjacency, free spins with the explorer selected is where the 5,000x ceiling lives.
