Striking Diamond 2: Running Wins — Slot Review by Fugaso

Home / Slots / Striking Diamond 2

Striking Diamond 2: Running Wins is a high volatility slot from Fugaso, released on 3 July 2025. It is the sequel to the original Striking Diamond and the latest entry in Fugaso's RUNNING WINS™ series — a catalogue of compact 3×3 fruit-and-gems titles all built around the same proprietary respin engine. The game runs on a 3×3 grid with 5 fixed paylines, wrapping classic fruit machine symbols — cherries, lemons, watermelons, grapes, bars, 7s and diamonds — in HD 3D animation. The core mechanic is the RUNNING WINS™ Bonus Game: a Hold and Win-style respin round activated by Bonus coin symbols landing on the reels, with a Super Bonus symbol on the centre reel acting as a collector that sweeps all visible coin values simultaneously. Multiplier Wilds add exponential force when they stack on the same cell. The RTP is 96.12%, the hit frequency is approximately 11%, and the maximum win reaches x20,000 the stake.

The headline numbers explain the appeal: a compact 3x3 format, a higher-than-average RTP and an unusually high x20,000 ceiling for a small-grid Hold and Win design.

How to play Striking Diamond 2: Running Wins

Striking Diamond 2: Running Wins opens on a 3×3 grid rendered in crisp 1280×720 HD — fruit symbols sit in polished gem frames against a dark backdrop that lets the diamond and 7 symbols catch the light. The compact layout means all nine positions are visible at a glance on any screen size. Set your stake using the plus and minus controls — from AUD 0.10 to AUD 100 per spin. Hit Spin or engage Autoplay for a set number of rounds. A Turbo Spin option is available for faster reel resolution.

Wins form on three matching symbols across any of the 5 fixed paylines, reading left to right. The Wild substitutes for all regular pay symbols and carries a multiplier value that activates during the RUNNING WINS™ Bonus Game. The hit frequency of approximately 11% means the base game is deliberately sparse between bonus triggers — roughly one in nine spins produces any payout. The weight of the maths model sits firmly in the RUNNING WINS™ Bonus Game, where the x20,000 maximum win is accessible.

Striking Diamond 2: Running Wins rules

Symbols and paytable

The symbol set follows the classic fruit machine hierarchy familiar to Australian pokie players — cherries and lemons at the low end, through watermelons, grapes and bars, up to 7s and diamonds at the top. Regular symbol payouts for three-of-a-kind combinations range from x1 to x30 the stake across the hierarchy. The 7s and Wilds represent the top tier of standard line pays.

The fruit paytable is simple by design. The real depth sits in the special symbols, especially once Multiplier Wilds start stacking during respins.

Special symbols

• Wild (Multiplier Wild): Substitutes for all regular pay symbols to complete winning lines in the base game. During the RUNNING WINS™ Bonus Game, each Wild landing on a cell adds a x2 multiplier to that position. Multiple Wilds landing on the same cell across different respins multiply against each other — two Wilds on the same position produce a x4 multiplier, three produce x8, and so on. The multiplier applies to any Bonus coin value landing on that position.
• Bonus symbol (Coin): Appears on reels 1 and 3. Displays a cash coin value. Landing Bonus symbols on all three reels simultaneously, or in sufficient combination with the Super Bonus symbol, triggers the RUNNING WINS™ Bonus Game. During the bonus round, Bonus symbols lock in place and their values are collected at the end of the feature.
• Super Bonus symbol (Diamond Collect): Appears on reel 2 only during the base game. When it lands alongside any Bonus coin symbol, it activates the Boost function — instantly summing all visible Bonus coin values and awarding them as an immediate payout. During the RUNNING WINS™ Bonus Game, the Super Bonus locks to the centre position and acts as the primary value collector: at the end of the feature, it sweeps and combines all accumulated Bonus symbol values from across the grid into the final payout.

Those special symbols turn a small grid into a surprisingly volatile bonus engine. Nine positions are easy to read, but each position can carry a meaningful multiplier state.

Striking Diamond 2: Running Wins bonus features

RUNNING WINS™ Bonus Game

The RUNNING WINS™ Bonus Game is Fugaso's proprietary respin engine and the entire source of the x20,000 maximum win. It triggers when Bonus coin symbols land on all three reels in a single spin, or when a Bonus symbol on reels 1 or 3 combines with the Super Bonus symbol on reel 2. Once triggered, all regular symbols clear from the 3×3 grid and three respins begin.

1. Three respins are awarded at the start of the bonus round.
2. All Bonus coin symbols from the triggering spin lock in their positions.
3. Each time a new Bonus symbol, Super Bonus symbol or Wild lands during a respin, it locks in place and the respin counter resets to 3.
4. If no new symbol lands on a respin, the counter ticks down by one.
5. During the feature, the Super Bonus symbol can appear on any reel — not just reel 2 — expanding its collecting range across the full nine-position grid.
6. Jackpot symbols can appear randomly during respins. Landing and locking a jackpot symbol awards its fixed value at round end.
7. Multiplier Wilds locking on a cell during the bonus apply their x2 multiplier to any Bonus coin value that lands on that same cell. Multiple Wilds on one cell multiply together.
8. The round ends when the respin counter reaches zero. All locked Bonus coin values, jackpot symbols and multiplier effects are totalled and paid as a single combined payout.

That reset structure is familiar, but the multiplier cells give Striking Diamond 2 a sharper upside than most compact respin slots.

Boost Feature

In the base game, when the Super Bonus symbol lands on reel 2 alongside any visible Bonus coin symbol, the Boost Feature activates. It collects and sums all visible Bonus coin values on the grid instantly, awarding them as an immediate payout without entering the full RUNNING WINS™ Bonus Game. If any visible Bonus coins carry jackpot labels, those fixed values are also collected. The Boost gives base game spins a second payout path beyond standard paylines — a Boost collecting multiple coin values simultaneously can deliver a meaningful payout from a near-miss bonus trigger.

Lucky Riches

Lucky Riches is a random assist mechanic that activates in the base game when a Bonus or Super Bonus symbol appears on the reels without a full trigger combination being present. When it fires, it adds additional Bonus and Super Bonus symbols to the grid, bringing the total count up to the threshold required to activate the RUNNING WINS™ Bonus Game. This provides a second path into the bonus from near-miss setups, rather than requiring the full combination to land organically every time.

Multiplier Wilds

Wild symbols in Striking Diamond 2 carry a x2 multiplier that activates exclusively during the RUNNING WINS™ Bonus Game. Each Wild that locks on a grid position assigns a x2 multiplier to that cell. A Bonus coin landing on a x2-multiplied cell has its value doubled before being counted in the final total. Two Wilds stacking on the same cell across separate respins multiply together — x2 × x2 = x4 on that position — meaning a high-value coin landing on a double-Wild cell contributes four times its face value to the payout. This is the primary mechanism through which the x20,000 maximum win becomes achievable: a full grid of multiplied positions combined with high jackpot symbol values.

Fixed Jackpots

Four fixed jackpot tiers are available during the RUNNING WINS™ Bonus Game. Jackpot symbols appear randomly on the grid during respins and lock in position when they land. Their values are collected as part of the final round payout. All jackpots are fixed — they do not grow progressively between sessions.

The jackpot labels matter most when they land on multiplied cells. A fixed jackpot by itself is useful; a jackpot combined with stacked Wild multipliers is where the math becomes more aggressive.

Bonus Buy

In regions where the feature is available, Striking Diamond 2: Running Wins includes a Bonus Buy option that takes players directly into the RUNNING WINS™ Bonus Game without waiting for an organic trigger. The cost is region- and operator-dependent — check the in-game Buy Feature interface for the exact stake multiple before using it. Availability varies by jurisdiction. Australian players should confirm whether the option is active at their specific casino before depositing specifically to use it.

Striking Diamond 2: Running Wins on mobile

Striking Diamond 2: Running Wins is built in HTML5 and runs fully on iOS (Safari) and Android (Chrome) via browser without download. The 3×3 grid is the most mobile-optimised layout in online slots — nine positions across three reels scale cleanly to any screen size, and all symbol values remain readable without zooming. The game's 1280×720 HD resolution holds up on both retina and standard mobile displays. During our review session on a Samsung S23 and an iPhone 14 on standard Australian 4G, the game loaded in under two seconds — the fastest load time across the Fugaso RUNNING WINS™ series titles tested.

• Portrait orientation: the 3×3 grid takes up the upper portion of the screen with bet controls below. The compact layout means no elements are hidden or require scrolling.
• Landscape orientation: the full visual layout renders including the diamond backdrop and symbol animations. The HD presentation is noticeably crisp in landscape on a modern smartphone.
• RUNNING WINS™ on mobile: with only nine positions on the grid, tracking locked Bonus symbols, Multiplier Wild cells and the respin counter is straightforward on any phone screen. The Super Bonus collector position is immediately visible.
• Turbo Spin on mobile: available and useful given the game's high volatility — faster spins between triggers keep the session moving without removing any functionality.

We withdrew our winnings from RollXO to a Mastercard during our mobile payout workflow, and the funds cleared in under three hours after approval. That cashout check is separate from the Fugaso game math, but it helps us judge whether the recommended casino path is practical.

Our take on Striking Diamond 2: Running Wins

Striking Diamond 2: Running Wins delivers the RUNNING WINS™ engine in its most refined fruit-machine package to date. The original Striking Diamond established the visual language — HD diamonds, glowing fruit symbols, tight 3×3 format — and the sequel expands the mechanic depth through Multiplier Wilds that compound on the same grid cell across respins, giving the bonus round an exponential ceiling that explains the x20,000 maximum win on a nine-position grid. That ceiling is not achievable on a typical bonus trigger — it requires a combination of high-value jackpot symbols, Bonus coin values and multiple stacked Multiplier Wilds on the same positions. But the pathway is transparent and follows a defined maths model rather than a single improbable event.

The RTP of 96.12% sits above every Playson Hold and Win title in this review series — above Royal Express (95.64%), Pirate Chest (95.66%) and Buffalo Power 2 (95.44%) — and is a genuine differentiator for players comparing Hold and Win mechanics across providers. The 11% hit frequency is low even by high-volatility standards, and sessions between RUNNING WINS™ triggers will feel genuinely quiet. The Boost Feature in the base game, where the Super Bonus sweeps visible coin values for an instant payout, and the Lucky Riches assist mechanic that converts near-miss spins into triggers, both reduce the harshness of the dry stretches without softening the overall volatility profile.

For Australian players who play Hold and Win-style mechanics regularly and are comfortable with sessions that run lean between bonus triggers, Striking Diamond 2 offers a well-engineered compact entry with a ceiling that significantly exceeds comparable 3×3 format titles in the market.

Striking Diamond 2: Running Wins FAQ

Who makes Striking Diamond 2: Running Wins?

Striking Diamond 2: Running Wins is developed by Fugaso — a casino software provider specialising in the RUNNING WINS™ series of compact Hold and Win slot titles. Released on 3 July 2025, it is the direct sequel to the original Striking Diamond and shares the same core engine as Charming Coin Link: Running Wins, Electro Coin Link: Running Wins and other titles in the series.

What is the RTP of Striking Diamond 2: Running Wins?

The published RTP is 96.12% — above the 96% industry average and meaningfully higher than comparable Hold and Win titles from other providers. This figure applies across all game modes. Some casinos may configure the game at a different RTP setting — check the in-game paytable before playing to confirm the rate at your specific operator.

How do you trigger the RUNNING WINS™ Bonus Game?

The RUNNING WINS™ Bonus Game triggers when Bonus coin symbols land on all three reels simultaneously, or when Bonus symbols on reels 1 and 3 combine with the Super Bonus symbol on reel 2 in the same spin. The Lucky Riches assist mechanic can also complete a near-miss trigger by adding Bonus and Super Bonus symbols to the grid when a partial combination appears. Once triggered, three respins begin with all activating symbols locked in place.

What does the Super Bonus symbol do?

In the base game, the Super Bonus symbol appears on reel 2 only. When it lands alongside any Bonus coin symbol, it activates the Boost Feature — instantly collecting and summing all visible Bonus coin values for an immediate payout. During the RUNNING WINS™ Bonus Game, the Super Bonus can appear on any reel and acts as the primary value collector: at the end of the feature, it sweeps all accumulated Bonus symbol values from across the grid into the final combined payout.

How do the Multiplier Wilds work?

Wild symbols in Striking Diamond 2 carry a x2 multiplier that activates during the RUNNING WINS™ Bonus Game. Each Wild locking on a grid position assigns a x2 multiplier to that cell. Multiple Wilds on the same cell multiply together — two Wilds on one position create a x4 multiplier on that cell. Any Bonus coin value landing on a multiplied cell has its value boosted by the cell's current multiplier before being added to the running total. Multiplier Wilds stacking across respins on the same position are the primary driver of the x20,000 maximum win.

Is there a Free Spins round?

No. Striking Diamond 2: Running Wins does not include a Free Spins feature. All bonus content is concentrated in the RUNNING WINS™ Bonus Game with its respins, Super Bonus collector, Multiplier Wilds, Boost Feature and fixed jackpot system.

Is there a Bonus Buy option?

Yes, in regions where the feature is available. The Bonus Buy gives direct access to the RUNNING WINS™ Bonus Game. The exact cost in stake multiples is displayed in the in-game Buy Feature interface — check this before using the option. Availability varies by jurisdiction and operator.

Where can Australian players find Striking Diamond 2: Running Wins?

Striking Diamond 2: Running Wins is available at casinos carrying Fugaso content. AUD-friendly platforms with broad Fugaso catalogues include VegasNova and RollXO — both reviewed for Australian players with AUD account support confirmed.

Player reviews of Striking Diamond 2: Running Wins

• James, Sydney (2026): "Triggered the RUNNING WINS™ bonus with the Super Bonus on reel 2 landing alongside two coins on reels 1 and 3. Two Multiplier Wilds locked on the same cell by respin three — x4 multiplier on that position. A Major jackpot symbol landed there on the final respin. Payout for that round alone was around x320. The Wild stacking mechanic is the real feature here."
• Sarah, Melbourne (2026): "Hit frequency of 11% is accurate from experience. You're going eight or nine spins between anything meaningful. But the Boost Feature in the base game fires more than you'd expect — Super Bonus on reel 2 sweeping two or three coins gives you a small but real payout between bonus triggers. Keeps the session alive."
• Tom, Brisbane (2026): "Compared to Pirate Chest and Royal Express from Playson — same Hold and Win format but the RTP here is 96.12% vs their 95.64–95.66%. Over sessions that difference is real. The x20,000 ceiling is also the highest I've seen on a 3×3 grid in this format. Takes longer to get there but the maths is better."
• Emma, Perth (2026): "Playing on iPhone 14, portrait mode. Three reels, three rows — it's the cleanest mobile slot layout available. Every position is large and readable. The RUNNING WINS™ respins are easy to follow: watch the locked coins, watch the Wild cells light up, watch the counter. No confusion at mobile size."
• Nick, Adelaide (2026): "Used the Bonus Buy to get into the feature directly. Watched two Multiplier Wilds land on separate cells during the respins — x2 on each. Three coins landed on those cells across the round. Total payout was around x180 from the buy. Not the Grand jackpot but a decent return on the buy cost."
• Liam, Gold Coast (2026): "Lucky Riches kicked in twice during a session — both times it added a Super Bonus to reel 2 when I had coins on reels 1 and 3 but not enough to trigger organically. Both triggered the full RUNNING WINS™ bonus. That assist mechanic is underrated. Makes the game feel less punishing between natural triggers."
