Theme, Soundtrack and Symbols

Expect even more excitement as 12 Coins™ Grand Diamond Edition takes the Coins™ series to new heights with its boosted features and rewards. The game offers a more engaging and dynamic betting experience with stunning diamond-inspired visuals and a fitting soundtrack.

If you’ve played any of the other Coins™ games like 25 Coins™, 15 Coins™ or the popular 9 Coins™ collection, then you’ll be familiar with the graphics and style. The 12 Coisn Grand Diamond Edition slot bears many similarities to the 9 Coins™ Grand Diamond Edition slot.

Game Mechanics

12 Coins™ Grand Diamond Edition is a 4-reel and 3-row slot from Wazdan. It features 12 paylines, and wins are formed with 3 or more matching symbols that pay from left to right.

You can enjoy the game across desktop and mobile devices for a minimum of €0.10 per spin. The slot has a function that enables you to play at a normal pace, fast, and in ultra-fast mode. You can also activate between 10 and 1000 automated spins with the autoplay function.

12 Coins™ Grand Diamond Edition has a return to player percentage of 96.14%, allowing you to choose your slot variance. Click on the chilli next to the spin button to select between low, medium and high volatility. While playing the slot, you can trigger 4 jackpots, of which the grand jackpot offers the maximum payout of 5,000x your stake.

Special Features

The slot breaks from the types of features you’ve grown accustomed to but offers a few bonus game options that enhance your betting experience.

Cash Out

During the base game, a Cash Out label can appear on a random reel and stick for up to 20 spins. If Cash, Cash Infinity, Mini, Minor, or Major jackpot symbols land on that reel, their value is collected. Once the Cash Out countdown reaches 0, a percentage ranging from 10% to 300% is randomly drawn. Then, that percentage of the bonus symbol value is paid out.

Cash Infinity Symbol

The Cash Infinity symbol can appear randomly in the base game and will stick to the reels until the end of the Hold the Jackpot bonus game. All the sticky cash infinity symbols remain locked in place while all other symbols are spun. If a sticky symbol appears, the outcome of the remaining non-sticky symbols is entirely random. The Cash Infinity symbol can award payouts of 5x to 15x your bet.

Hold the Jackpot Bonus Game

All bonus symbols stick to the reels during the bonus game. You get 3 respins at the start of the bonus game, and with each new bonus symbol that lands, the respin count is reset to 3. This continues until the respins are finished or the reels are filled with bonus symbols. During the feature, you can get cash symbols that award prizes ranging from 1x to 10.

You can also hit the Mini, Minor, or Major jackpot. The collector symbol will collect all the values from cash and cash infinity symbols and can randomly multiply them by 1x to 20x. The jackpot mystery symbol can only transform into mini, minor, and major jackpot symbols. To win the Grand jackpot, you must collect 12 bonus symbols. Hitting the Grand jackpot awards a maximum payout of 5,000x your stake.

Chance Level

You can increase your chances of hitting the Hold the Jackpot Bonus Game via the base game.

Chance Level x2 – Base bet is multiplied by 2 and increases your chances by 2x to trigger the jackpot bonus game.
Chance Level 5x – Base bet is multiplied by 5, increasing chances to hit the jackpot bonus game by 6x.
Chance Level 10x – Base bet is multiplied by 10 and increases chances to hit the jackpot bonus game by 13x.

Gamble Feature

After a win, you can manually activate the gamble feature to double your wins. It’s a simple guess-the-colour game where you can choose black or red. Guess correctly to double your wins. Or collect your wins and continue your gameplay.

Play ‘On The Go’

The game's simplicity makes it almost ideal for mobile devices, above other devices. Thanks to the lack of game clutter, you can enjoy a smooth, lag-free betting experience across any iOS or Android device.

When you play on mobile, all features, special options, and betting limits remain the same. All that changes is the game layout, which adapts to fit your device screen size. It enhances the mobile experience as you spin the reels to unlock the Grand jackpot payout.

CasinoWow Game Verdict

Looking for something fresh, fun and simple? CasinoWow highly recommends the 12 Coins™ Grand Diamond Edition. Enjoy the gold theme and almost mystical feel on desktop or mobile, and set up the gameplay to work for your budget and according to your preference.

While a free spins feature or something wouldn’t hurt, it’s an enjoyable slot that offers the opportunity to take home big wins of up to 5,000x your stake. Try the demo on CasinoWow or play for real money at top Wazdan-powered online casinos. Try now!
