Sunstone Riches Slot by Evoplay

Bonus symbols land on the outer reels only. Sun-Bonus symbols land on the middle reel only. That split is the whole game. Two Bonus hearts on reels 1 and 3 plus one gold Sun-Bonus on reel 2 starts the Hold and Win round, and the asymmetric 3-5-3 grid makes the middle reel five rows tall while the edges stay at three. More collector positions in the center, fewer value symbols on the sides.

Inside the bonus, 3 respins tick down. Each new Bonus or Sun-Bonus resets the counter. Bonus symbols carry multipliers (1x through 15x) or one of four fixed jackpots - Mini at 25x, Mega 50x, Super 150x, Grand 1,000x. When a Bonus symbol lands, its value gets added to every Sun-Bonus collector sitting on that wide middle reel. Stack three or four Sun-Bonus symbols and a single 15x Bonus hit pays 45x or 60x in one shot. The Grand jackpot through multiple collectors is where the big numbers come from. A random Sun Gifts trigger fires on dead spins, dropping enough symbols to force a bonus entry - a safety valve for the dry stretches.

Warm orange light washes over a stepped Aztec pyramid in the background, and the symbol set splits between tropical fruit on the low end (avocado, mango, papaya) and gold ceremonial pieces up top - a snake deity, a golden mask, and a woman character paying 15x as the best regular symbol. The fruit gives it an almost classic-slot feel that contrasts with the adventure theme. Buy Bonus runs 74x, which is on the expensive side for a game in this max win range. Wilds only appear in the base game and don't carry into the bonus round at all, so the base game and bonus feel like two different slots sharing the same grid.
