Treasures of the Mystic Sands Slot by Genii

Two features, one in each mode, with no overlap. The base game runs Random Wild, where the engine picks a symbol at random on a given spin and converts every instance of it into a wild for that spin only. It does not show up in Free Spins. Free Spins, in turn, run a feature that never appears in the base, and the split is the most useful thing to know about how this game plays.

That Free Spins feature is the Mega Reel. Reels 2, 3 and 4 fuse into a single 3x3 mega-position, and after each spin the symbol that lands on the centre row of reel 3 expands to fill all nine of those positions. Every free spin, you get one symbol covering the whole middle of the grid, with reels 1 and 5 spinning normally on either side. Across 10 fixed paylines, that means most lines cut straight through the same expanded symbol, so a premium landing in the middle pays on multiple lines at once.

Trigger conditions are 3, 4 or 5 scatters for 8, 10 or 15 spins, no retrigger inside the round and no buy option to skip the wait. With the top regular paying 500 coins for five-of-a-kind, a Mega Reel locking the bearded sultan in red turban across the middle nine positions is what the 6,500-coin ceiling actually looks like in practice. Around 162x your total bet at the cap, which is a modest number for a 2025 release with this much bonus structure.

Visually it sits inside a stone archway looking out on a sunset cityscape of mosque domes in dusty pink and orange, with palm fronds drooping in from either side. The reel canvas itself is hot magenta with a heavily patterned gold border, and the carved treasure chest spilling gems is the second-highest pay. Card royals are gold medallions with green vine accents, not the usual flat letters.
