The 9 Coins Grand Diamond Edition slot machine represents the pinnacle of Wazdan's popular series, delivering the most engaging gameplay and powerful mathematical model yet. This online slot showcases Wazdan's signature cosmic aesthetic with its stunning gold and crimson color palette set against a mysterious space backdrop.

What sets this slot apart is its revolutionary Chance Level ante bet system, which can amplify your Hold the Jackpot bonus triggering odds by an unprecedented 13x multiplier - the highest enhancement rate in the industry. The base game introduces an exciting Cash Out symbol mechanic that can significantly boost your winnings, especially when combined with the lucrative Cash Infinity symbol for explosive combinations.

The Hold the Jackpot bonus round features an array of specialized symbols, and completely filling the grid unlocks the impressive 5,000x stake potential.

About Wazdan: This award-winning game provider has been crafting exceptional casino games since 2011, with an impressive portfolio of 185 titles (including 165 video slots). Renowned for their customizable volatility features, Wazdan has established a distinctive visual universe that's instantly recognizable in the online casino world.

9 Coins Grand Diamond Edition Volatility And Max Win

This premium slot machine offers players complete control over their gaming experience through customizable volatility settings (low, standard, or high) - a signature feature across all Wazdan slots. The 9 Coins Grand Diamond Edition maximum win reaches an impressive 5,000x your stake, representing the highest payout potential ever achieved in the 9 Coins series.

9 Coins Grand Diamond Edition Game Rules And Mechanics

Unlike traditional slot machines, this game operates without standard paying symbols, yet offers exciting winning opportunities through the Cash Out feature during base gameplay. The betting range spans from £0.20 to £10,000 per spin, accommodating both casual players and high-stakes enthusiasts.

The primary objective involves landing 3 bonus symbols on the center row to activate the lucrative Hold the Jackpot Bonus Game where the biggest wins await.

Symbols And Payout Structure

The 9 Coins Grand Diamond Edition symbol collection focuses exclusively on bonus symbols rather than traditional paying icons. The reels feature various cash symbols and Cash Infinity symbols, while the special Cash Out symbol creates winning opportunities during regular spins through its unique payout mechanism.

9 Coins Grand Diamond Edition Bonus Features And Special Mechanics

This advanced slot machine incorporates familiar mechanics from previous 9 Coins releases while introducing groundbreaking enhancements, particularly the upgraded Cash Out feature that offers exciting new winning possibilities and substantial payout potential.

Chance Level Enhancement (not UK)

The Chance Level ante bet system in 9 Coins Grand Diamond Edition reaches new heights with industry-leading multipliers:

• 2x stake payment = 2x Hold the Jackpot triggering chances • 4x stake payment = 5x Hold the Jackpot triggering chances
• 6x stake payment = 8x Hold the Jackpot triggering chances • 10x stake payment = 13x Hold the Jackpot triggering chances

Cash Out Bonus Mechanic

The Cash Out label symbol appears randomly and remains sticky for up to 20 spins with a countdown timer. When the counter reaches zero, any Cash, Cash Infinity, or Jackpot symbols (mini, minor, major) on the same reel trigger a payout calculation.

The Cash Out symbol reveals multipliers of 10%, 100%, 150%, or 200%, determining your winning percentage from the qualifying symbols on that reel.

Cash Infinity™ Symbol

The distinctive red Cash Infinity coin becomes sticky until the next Hold the Jackpot bonus concludes. Each symbol carries a random prize value between 5x to 15x your stake.

When appearing on the middle row, it helps trigger the bonus game by remaining in position. The real excitement occurs when Cash Infinity symbols align with Cash Out countdown symbols - the prize value accumulates with each spin until the counter expires, potentially reaching 300x your stake from a single symbol.

9 Hold the Jackpot Bonus Round

Regular cash bonus symbols offer values from 1x to 9x your stake, while the Mini, Minor, and Major jackpots provide 10x, 20x, and 50x respectively.

Special Symbol Functions: • Treasure Chest Collector - Gathers all cash and cash infinity values, applying a random x1 to x20 multiplier • Mystery Symbols - Transform into any bonus symbol (excluding cash infinity) when the feature ends • Jackpot Mystery Symbols - Reveal one of the three jackpot symbols

The feature concludes by collecting all bonus symbol values as your prize. However, filling all 9 positions triggers the Grand Jackpot worth 5,000x your stake - the game's ultimate maximum win.
