Sunstone Riches Slot Overview

An Aztec temple at sunset, a pile of tropical fruit, and a sun mask that swallows every gem on the board. Sunstone Riches is Evoplay's hold-and-collect game squeezed onto three reels, and the squeeze is the interesting part.

The grid is lopsided on purpose. Reels 1 and 3 are three symbols tall, the middle reel is five, and that 3-5-3 shape is what produces the 45 ways to win. It also splits the game into jobs: the outer reels carry the red gems that hold cash values, the tall centre reel carries the Sun that collects them. You can read the whole trigger at a glance, which is rare in a modern hold and win title.

Regular pays are small. The Aztec woman, top of the chart, gives 15x bet for three. Everything meaningful comes out of the Bonus Game, where the ceiling sits at 8,292x, a shade above the 8,200x the game advertises for itself.

Theme & Design

The backdrop is a stepped pyramid in warm sunset orange, softened by haze, with dense jungle green creeping across the bottom of the frame. Each of the three reels sits in its own carved stone panel with fretwork borders, and a small golden temple with lit braziers perches on top of the right-hand reel like a finial. The premium symbols are the strongest art here: a masked woman in a gold headdress with violet face paint, a pair of inlaid gold drinking cups, and a turquoise feathered serpent with a red crest.

The fruit ruins it a bit. Pineapple, dragon fruit, papaya, mango, tomato and avocado are rendered like supermarket photography, glossy and modern, sitting right next to hand-carved stone. Evoplay clearly wanted the classic fruit-machine read, and it works mechanically, but the two art styles never meet. The four jackpot plaques stacked down the left in red, blue, green and purple are clean and readable, and the sound stays low and percussive until a gem lands.

Features & How They Work

45 Win Ways across 3-5-3

Wins pay left to right across all three reels, any position, so a combination always needs one symbol from each reel. Three tall by five tall by three tall gives 45 combinations, and payouts are multiplied by the number of ways a symbol hits. The middle reel does the heavy lifting: a symbol stacked three deep in the centre triples what the same combination pays elsewhere. Wild substitutes for the nine regular symbols and appears only in the main game.

Bonus gems and the Sun-Bonus

Red heart-shaped gems land only on reels 1 and 3, each stamped with a value between 1x and 15x bet, or with one of four jackpot names. The gold Sun-Bonus lands only on reel 2. Neither pays anything in the base game on its own. Two gems plus one Sun start the Bonus Game, and that is the only combination that does it.

Bonus Game

Regular symbols fade off the board and the reels switch to a set containing nothing but gems, Suns and blanks. You get three spins. Every new gem or Sun that lands resets the counter back to three, so a hot streak keeps extending itself, and a cold spin ends it fast. Suns lock in place for the rest of the round. When it finishes, every Sun on the board collects the value of every gem on the board, meaning the same pot gets paid once per Sun. Five Suns on that tall middle reel is the route to the top number, and it is a long route.

Four fixed jackpots

GRAND pays 1,000x bet, SUPER 150x, MEGA 50x and MINI 25x. These arrive as jackpot-branded gems inside the Bonus Game rather than through a separate wheel or pick round, and they are fixed multipliers of your stake, not progressives that grow between players. Because a jackpot gem is just another value for a Sun to collect, landing GRAND with two Suns on the board pays it twice.

Sun Gifts

On any base-game spin that produces no winning combination but drops a gem or a Sun, this can fire and drop in whatever extra symbols are needed to complete the trigger. It is an anti-frustration valve, and a well-judged one, since the three-piece trigger would otherwise tease constantly.

Bonus Buy

The bonus buy costs 74x total bet and guarantees one Sun plus two to four gems with random values. RTP shifts down slightly to 95.94% when you buy, against 96.06% on regular spins. Not available in every market.

How Sunstone Riches Plays

Base spins are quiet. Three matching fruits pay back a fraction of the stake, the counter ticks down, and for stretches nothing on the board matters except whether a red gem shows up on an outer reel. When one does, the game gets legible in a way most slots aren't: you need exactly three things, you can see all three reels at once, and you know instantly whether the spin is alive. Two gems and no Sun is the most common way to be disappointed here, and you'll see it a lot.

The Bonus Game is short and it moves. Three spins is barely any runway, so the whole round hangs on whether the resets keep firing, and a round that stalls at two Suns and a handful of 2x gems is over in about fifteen seconds with 40x on the counter. That is the honest median outcome. The good ones build visibly, one Sun at a time, and because each new Sun re-pays the entire pot you can feel the total jump rather than creep.

What's missing is any middle gear. There are no free spins, no multiplier ladder, nothing between the fruit trickle and the bonus, so sessions run as long flat stretches punctuated by one event (and yes, plenty of hold-and-win games have this problem). Sun Gifts softens it. It doesn't fix it.

Pros & Cons

Pros

  • The 3-5-3 grid makes the bonus trigger instantly readable, and gives the collect mechanic a natural home on the tall centre reel
  • Each Sun collects the full pot, so bonus totals scale sharply instead of adding up linearly
  • Sun Gifts quietly rescues dead spins into bonus entries
  • Bet range from 0.10 to 7,500 covers penny play and high stakes on the same game

Cons

  • Base game has nothing to do between bonuses; no free spins, no multipliers, just small fruit pays
  • 74x for the buy is steep against a bonus that usually lands well under that
  • The photo-real fruit clashes badly with the carved stone art everywhere else
  • Two gems without a Sun is a constant near-miss, and it gets old

Is Sunstone Riches Worth Playing?

6/10

Evoplay took a mechanic that normally needs a 5x3 or bigger board and made it work on three reels by making one of them taller. That's a smart bit of design, and the collect maths that follow from it are the best thing here: a pot that gets paid once per Sun climbs fast when it climbs at all. The Aztec dressing is handsome, if let down by fruit symbols borrowed from a different genre.

The limitation is how little happens outside the bonus round. High volatility on a game with one feature and no free spins means the balance graph is a staircase down with occasional cliffs upward, and at 96.06% you're not being compensated with anything unusual. The 8,292x ceiling is honest enough as a number but needs the tall reel packed with Suns while a GRAND gem sits on an outer reel, which is about as rare as it sounds. For a quick, clear, low-clutter collect game it does the job. Anyone who wants variety inside a session will find it thin.

Frequently Asked Questions

What is the maximum win in Sunstone Riches?

8,292x your bet. The game itself advertises 8,200x, so the true ceiling is marginally higher than the marketing number. Reaching it requires a Bonus Game with the middle reel full of Sun-Bonus symbols collecting high-value gems including the GRAND.

How do you trigger the Bonus Game?

Land two Bonus gems, one each on reels 1 and 3, together with a Sun-Bonus symbol on reel 2. The Sun Gifts feature can also complete the trigger at random on a non-winning base-game spin.

Are the jackpots progressive?

No. GRAND, SUPER, MEGA and MINI are fixed multipliers of your bet, paying 1,000x, 150x, 50x and 25x. They land as jackpot-marked gems during the Bonus Game and get collected by the Sun symbols like any other value.

What is the RTP and can you buy the bonus?

RTP is 96.06% on normal spins. The bonus buy costs 74x total bet and lowers RTP slightly to 95.94%, and it may be unavailable depending on your market.

Can I play Sunstone Riches for free, and is there an age requirement?

The demo runs with play money and no registration, so you can test the Bonus Game without risking anything. Real-money play is restricted to players aged 18 or over, or the legal minimum in your jurisdiction. Set deposit limits before you start and stop if it stops being fun.
