Temple of Dead Bonus Buy Slot by Evoplay

A torchlit Egyptian temple sets the stage, with carved stone pillars framing a 5x3 grid bathed in deep amber light. The Scatter symbol doubles as the Wild and substitutes for everything else on the reels. Land three or more Scatters anywhere to trigger 10 free spins - and during those free spins, three more Scatters add another 10 on top.

Before the free spins round starts, one regular symbol is randomly chosen as the Expanding Special. Whenever enough of that symbol lands to form a winning combination, it stretches to fill all three rows on its reel. The expansion kicks in only after standard wins have been calculated, so you get paid twice - once for the original positions, then again after the symbol expands. And the Expanding Special forms winning combinations even across non-adjacent reels, which is unusual for a 10-line game.

The Bonus Buy panel on the left side of the screen offers three tiers: 10 free spins at 75x your total bet, 20 at 148x, or 30 at 221x. Each option selects a random Expanding Special, so you skip the base game grind entirely. The mechanic mirrors the classic Book of Dead formula - Scatter-as-Wild, expanding chosen symbol, Egyptian setting - but the triple-tier buy feature and the retrigger option during purchased spins give it a distinct identity.
