Hidden City Slot by BigPot Gaming

Twelve free spins with synced reels - that's the Hidden Mirror, and it's the only feature. Each free spin picks two reels at random and copies identical symbols across them. Mid-spin, the sync expands to three, four, or all five reels. Five reels showing the same result across 30 paylines gets crowded with matches fast. Buying into the bonus directly skips the scatter alignment (reels 1, 3, and 5 all need to land simultaneously), though the price only displays inside the game.

No multipliers, no sticky wilds, no progressive layers. The base game is a straight 30-payline left-to-right slot where the Wild marquee sign substitutes for everything and the scatter does nothing except count toward the bonus trigger. All the math sits inside those 12 synced spins and whether the mirror decides to copy two reels or five. A golden lion statue guards the left side of the grid behind a velvet rope, searchlights sweep across a nighttime skyline full of skyscrapers, and every symbol plays into the VIP-club theme - whiskey bottles, gold watches, bundled cash, black cards embossed with a monogram. The poker chip card royals in green, purple, and red are the one design choice that actually fits a casino setting without trying too hard.
