Sunstone Riches Slot by Evoplay

A Grid That Actually Matters

Sunstone Riches runs on a 3-reel setup, but calling it a 3-reel slot doesn't tell the full story. The left and right reels hold 3 symbol positions each. The middle reel? Five. That gives you a 3-5-3 layout with 45 Win Ways, and the shape isn't cosmetic. It determines everything about how the bonus triggers and how wins accumulate.

Evoplay built this around fruit symbols at the bottom of the paytable (avocado pays 0.5x, mango and tomato at 1x) and Aztec artifacts at the top. The woman character is the best regular symbol at 15x per bet, followed by a golden mask at 10x and a ceremonial cup at 8x. Three matching symbols across all three reels, left to right, in any row position. Simple.

The Sun-Bonus Collection Engine

Here's where the grid shape earns its keep. Bonus symbols (red heart gems carrying random multiplier values) land only on reels 1 and 3. Sun-Bonus symbols (gold suns) land only on reel 2. Get one Sun-Bonus on the oversized middle reel and Bonus symbols on both outer reels, and the Bonus Game fires.

Once inside, you start with 3 respins. Every new Bonus or Sun-Bonus that lands resets the counter back to 3. Regular symbols disappear. The reels now contain only Bonus symbols, Sun-Bonus symbols, and blanks.

Each Bonus symbol carries a value: 1x, 2x, 3x, 5x, 7x, 10x, 12x, or 15x your bet. Or one of four fixed jackpots. When a Bonus symbol lands, its value flies into every Sun-Bonus on the grid. So if you've collected three Sun-Bonus symbols on that wide middle reel, each Bonus hit gets tripled across all of them. The snowball effect is real.

Jackpot values on Bonus symbols: MINI pays 25x, MEGA 50x, SUPER 150x, GRAND 1,000x. All fixed, not progressive. Landing a GRAND symbol when you've got multiple Sun-Bonus collectors active is where the 8,292x max win lives.

Sun Gifts and the Buy-In

Dead spins that produce no wins have a chance to trigger the Sun Gifts feature. When it fires, the game drops Bonus and Sun-Bonus symbols onto the reels itself, guaranteeing a Bonus Game entry. It's an anti-frustration mechanic, and a welcome one given the high volatility. You won't know when it'll hit, but knowing it exists takes some edge off dry stretches.

Prefer to skip the wait? The Bonus Buy costs 74x your bet. That's steep for a game capped around 8,200x - you're burning about 0.9% of your max win potential on a single entry fee. The buy triggers 1 Sun-Bonus and 2 to 4 Bonus symbols with random values. RTP during bought rounds drops slightly to 95.94% from the base game's 96.06%.

What the Numbers Say

At 96.06% RTP with high volatility, Sunstone Riches sits in standard territory for modern slots. No configurable tiers, which is a plus - you get one version everywhere. The 45 Win Ways keep individual spins cheap relative to the bet, but also mean base game wins tend to be modest. Most of the upside is locked inside the Bonus Game.

The bet range is unusual. Minimum 0.10 is normal. Maximum 7,500? That's one of the widest bet ranges you'll see from any provider. High rollers can push serious money through this, though whether a game with 8,292x max win deserves bets that large is a different question.

The asymmetric grid is the real differentiator. Most Hold & Collect games use a flat 5x5 or 5x3 layout. Evoplay's decision to concentrate the collector on the expanded middle reel while restricting value symbols to the narrow outer reels creates a natural tension. You want Sun-Bonus symbols on reel 2 (more positions = more chances), but you need Bonus hits on the tight 3-row edges to feed them. The geometry forces the math to work differently than a standard Hold & Win round, and the result feels less formulaic than most games in this category.
