Understanding the game’s mechanics is straightforward. The 12 Coins Grand Diamond Edition gameplay unfolds on a 4×3 grid. It features 12 fixed ways to win on every spin. This simple setup allows players to focus on the bonus symbols.
The betting options accommodate everyone. You can place bets from a minimum of 0.2. Alternatively, high rollers can wager up to 10000 per spin. The game’s 96.14% RTP is quite favorable.

💡 Pro Tip: Use the Bonus Bet feature to increase your chances of triggering the Hold and Win round without paying the full price of the Buy Feature.
The Hold and Win feature is the game’s main attraction. Landing the right symbols triggers this exciting bonus round. During the feature, Sticky Symbols lock in place for respins. Filling the entire grid with symbols awards the Grand Jackpot. This is your key to achieving the maximum payout.
Several other mechanics enhance the gameplay. Mystery symbols can land and transform into other bonus icons. This adds a layer of surprise and can trigger random rewards. Additionally, the Bonus Bet option increases your bonus chances. You can also use the Buy Feature for direct entry into the action. After any win, the Risk/Gamble game offers a chance to double your prize. This suite of features creates a truly dynamic experience.
⚡ Quick Fact: The Hold and Win bonus is the only way to win the 5,000x Grand Jackpot, making it the most important feature in the game.
This game operates on a High volatility math model. This design suits players with patience and a solid bankroll. You may experience longer periods without wins. However, the potential for substantial payouts is much higher. It is a classic high-risk, high-reward slot machine.
The developer has not disclosed the official Hit Frequency for this game. Based on its high volatility, triggering the bonus may take time. This makes the Bonus Bet and Buy Feature very useful tools. The maximum win is firmly capped at x5000.00 your bet. This prize is exclusively available through the Grand Jackpot. The game’s payout profile is therefore ideal for jackpot chasers.
⚠️ Caution: High volatility games can deplete your balance quickly. Always set a budget and play responsibly. Consider using resources from organizations like BeGambleAware.
