12 Coins Grand Diamond Edition by Wazdan offers an exciting treasure-hunting adventure featuring innovative Cash Out labels that can multiply your base game wins by up to 300%. This cosmic-themed slot delivers the thrilling Hold the Jackpot Bonus with collector multipliers, and filling the entire grid awards the spectacular 5,000x Grand Jackpot maximum payout.

12 Coins Grand Diamond Edition Slot Review

The 12 Coins Grand Diamond Edition represents the pinnacle of Wazdan's acclaimed Coins series, delivering an exceptional gaming experience packed with innovative features. This slot stands out with its customizable volatility settings across three levels, adjustable spin speeds, and the groundbreaking Cash Out Labels mechanism that enables base game victories. The bonus symbol payouts can receive impressive boosts of up to 300%, elevating the excitement to new heights.

The primary objective revolves around activating the signature Hold the Jackpot Bonus Round, where cosmic treasure themes blend seamlessly with diamond-encrusted visuals. The slot's flexible betting range accommodates all player types, from casual spinners to high-stakes enthusiasts. Wazdan's trademark customization options allow players to tailor their experience with preferred volatility levels and spin speeds.

The Hold the Jackpot feature showcases classic Wazdan innovation, incorporating multiplier collector symbols, jackpot icons, and mystery symbols that unveil bonus rewards and jackpot prizes for maximum entertainment value.

Wazdan - Game Provider

Since establishing themselves in 2011, Wazdan has become renowned for creating extensive slot series with multiple branching sub-series. The Coins collection stands as their flagship range, with the developer having crafted over 200 premium games to date. Their primary expertise lies in developing captivating and innovative video slots, successfully establishing a distinctive presence within the competitive iGaming landscape.

Game Theme And Visual Design

Featuring a stunning turquoise cosmic backdrop adorned with shimmering stars, nebulas, and sparkling diamonds, the 12 Coins Grand Diamond Edition slot transports players on an interstellar quest for fortune and wealth. The game grid showcases treasure chests, gleaming golden coins, and elegant diamond-style mystery symbols. Each position displays the game logo with subtle purple accents that harmoniously blend with the dark celestial background, while the accompanying soundtrack creates an immersive and relaxing gaming atmosphere.

Volatility And Maximum Win Potential

This Wazdan creation offers above-average performance compared to industry standards. A standout feature includes the three-tier volatility selection: low, standard, or high settings to match your playing style. Players can also customize their spin speed across three different levels, while the 12 Coins Grand Diamond Edition maximum win reaches an impressive 5,000x your total stake.

Game Rules And Core Mechanics

Unlike traditional slots with standard paylines or symbols, 12 Coins Grand Diamond Edition operates through a unique system where victories occur via the innovative Cash Out Labels feature. These labels appear randomly across positions, automatically cashing out bonus symbols that land in labeled positions when their countdown timer expires.

The slot accommodates a betting range from €0.2 to €10,000 per spin, making it accessible to all player budgets. To activate the coveted Hold the Jackpot bonus round, players must land bonus symbols across all four middle row positions simultaneously.

Bonus Features And Special Mechanics

The semi-sticky Cash Out Labels provide substantial base game winning opportunities from bonus symbols, while eligible players can enhance their Hold the Jackpot activation chances through the Chance Levels feature. A comprehensive bonus buy option offers five different purchase levels for immediate bonus access.

Chance Levels Feature (Restricted in UK)

The Chance Levels function as optional ante bets that significantly boost your Hold the Jackpot Bonus activation probability:

• 2x stake payment increases bonus round chances by 2 times • 5x stake payment increases bonus round chances by 6 times
• 10x stake payment increases bonus round chances by 13 times

Cash Out Labels Mechanism

Cash Out labels appear randomly during base game spins and can remain sticky for up to 20 consecutive spins. When cash, cash infinity, or jackpot symbols land within a Cash Out label-framed position as the countdown reaches zero, players receive 10%, 100%, 150%, 200%, or 300% of the symbol's value as an instant payout.

Cash Infinity Symbol Mechanics

The Cash Infinity symbol carries values ranging from 5x to 15x your stake and maintains its position until the next Hold the Jackpot bonus round concludes. These special symbols can contribute to triggering the Hold the Jackpot bonus when they appear on the crucial middle row.

Hold the Jackpot Bonus Round

Triggering the Hold the Jackpot Bonus requires landing bonus symbols across all center row positions. All qualifying bonus symbols from the triggering spin become sticky on the dedicated 12-position bonus grid.

You begin with 3 respins, with the counter resetting to 3 whenever new bonus symbols appear. The bonus features include:

• Cash symbols with values from 1x to 10x your stake • Mini, Minor, and Major jackpots worth 10x, 20x, and 50x respectively
• Collector symbols that absorb all cash and cash infinity values while adding 1x to 20x multiplier boosts • Mystery Symbols that transform into bonus symbols when the feature concludes • Jackpot Mystery symbols that reveal one of the three jackpot symbols

The bonus round ends after 3 consecutive non-winning spins or when the entire grid fills with bonus symbols. Filling the complete grid awards the spectacular 5,000x Grand Jackpot, replacing all other accumulated winnings.

Bonus Buy Options (Unavailable in UK)

Eligible players can instantly purchase different Hold the Jackpot bonus variations using the shopping cart button beneath the reels. Available purchase options include:

• 50x stake - Low volatility bonus version • 100x stake - Standard volatility bonus version • 300x stake - High volatility bonus version
• 600x stake - Extreme volatility bonus version • 900x stake - Double extreme volatility bonus version

Higher payment amounts guarantee more valuable triggering symbols for enhanced winning potential.

Final Review And Expert Verdict

12 Coins Grand Diamond Edition represents the crowning achievement of Wazdan's acclaimed 12 Coins sub-series, delivering an exceptional finale to this beloved collection. While this particular branch may be concluding, players can explore numerous other exciting sub-series within the extensive Coins range.

The Cash Out labels showcase Wazdan's innovative approach, not only enabling base game victories but potentially boosting wins by up to 300%. This feature maintains constant engagement and excitement as players anticipate the percentage multiplier outcomes.

This title stands as the superior 4x3 grid option within the Coins collection, with the diamond theme integration beautifully enhancing the visual presentation. The Hold the Jackpot bonus remains the primary objective, while cash infinity symbols provide unexpected assistance at crucial moments.

The multiplier collector symbols add tremendous excitement, as players eagerly await the multiplier boost reveals. The 5,000x maximum win potential establishes 12 Coins Grand Diamond Edition as an exceptionally appealing and rewarding slot experience.
