28 Mansions Slot by Playtech

The reels answer to the four beasts of the Chinese sky. Old astronomy carved the heavens into 28 lunar mansions, and each quarter kept a guardian: the Azure Dragon in the east, the Vermilion Bird (a plumed red firebird) in the south, the White Tiger in the west, and the Black Tortoise, really a shelled dragon-turtle, in the north. All four show up as gleaming gold statues, coiling and roaring against a deep-red brocade laced with gold scrollwork. They're the top payers on this Chinese astronomy board, ranked above jewelled gold royals and a golden treasure junk.

The coin is what you're really chasing. A big golden Prosperity Coin, ringed in fire and stamped with a cash figure (€5, €15, whatever the spin deals out), lands one at a time. Get enough of them on screen and they lock, triggering Prosperity Spins: a coin hold-and-win respin round where nothing but the coins counts. Each locked coin keeps its printed value, and some carry more than cash. They can hold one of the jackpots instead. A Prosperous Choice pick sits inside the round for an added decision along the way.

Four meters glow above the grid the entire time, Grand through Mini, seeded in the demo at €10,000 / €1,250 / €250 / €100. Those pay out through a Jackpot Pick, a pick-a-symbol bonus where the Grand has two routes: choose three dragons, or fill the whole screen with gold coins. There's no buy option and no ante, so the coins have to arrive on their own steam.
