9 Coins™ Grand Diamond Edition (Wazdan) – Review & Demo Play

Top-performing 9 Coins series in 9 Coins Grand Diamond Edition

I have spent time with 9 Coins Grand Diamond Edition and it feels like a strong carry-on for the player-favourite series. The presentation is clean and the loop focuses on coins rather than paylines, which suits the format. Familiar parts return, then get expanded. Hold the Jackpot, Chance Level and Cash Out set the rhythm, with quick steps between base game nudges and bonus pressure. It keeps the pace tidy while sticking to the series' simple pick-style flow.

Across nine reels and no lines, the grid sticks to the 3x3 coin panel that fans expect. The Grand Jackpot worth 5000x bet sits in the bonus, so the session leans on feature entries rather than line hits. Volatility Levels let me set the mood, while the Buy Feature is there when I want straight access. It launched in 2023 and slots neatly into the series as a polished iteration with a tight feature mix and direct goals.

Chance Level in 9 Coins Grand Diamond Edition

Chance Level lets me multiply my stake up to 10x to hike the odds of entering Hold the Jackpot. It is a simple lever with real weight, because the top prizes live in the feature. I like setting a low level during testing, then jumping higher when the grid feels warm. It does not change RTP from what I can see in the spec, it just adds more entries, so bankroll planning becomes a key part of the choice.

Cash Out in 9 Coins Grand Diamond Edition

Cash Out adds a slow burn in the base game. A Cash Out label gathers values from any Bonus symbol that lands on it, then pays a percentage after 20 spins. That rolling tally gives me something to eye between feature triggers. I have seen small top-ups tick through at steady intervals, which takes the sting out of blanks. It is not a full bonus, more of a side pot that keeps numbers moving while the main chase builds.

It also nudges bet sizing choices. If I am close to the payout step, I might hold the stake and cycle the count, rather than switching pace. When the label resets, the loop returns to the usual coin hunt, so I treat Cash Out as a background extra. Paired with Chance Level, it frames the session with short windows where value can surface even without hitting the headline feature. It feels fair and steady rather than swingy.

Hold the Jackpot in 9 Coins Grand Diamond Edition

Hold the Jackpot is the series staple and still the headline here. The bonus rolls out with that familiar build and hands out generous prizes when the grid fills well. The Grand Jackpot sits as the top target, and the chase has a nice pull without dragging the pace. It remains a highly satisfying segment of play and gives the slot its identity, which is exactly what I want from a 9 Coins release.

The interplay with other mechanics matters. Cash Infinity symbols can stick on the reels and carry into this mode, staying until the end and helping with the route to the Grand Jackpot. That setup adds tension before the trigger, because sticky values waiting on the grid make any entry feel loaded. When it lands, you get a clean focus on collecting coins and filling positions, with payouts mapped to what you have banked and what drops in.

9 Coins Grand Diamond Edition Symbols and Paytable

The paytable revolves around Special symbols rather than line wins, which fits the 3x3 coins format. Special entries carry values that feed Cash Out on the label and come alive during Hold the Jackpot. There is also a Multiplier symbol noted in the spec, lining up with the series idea of stacking value within the feature. It is a plain approach by design, so reading the paytable takes seconds and the focus stays on landing the right coin set.

Features in 9 Coins Grand Diamond Edition

Energy Saving Mode is handy on mobile and, by the spec, can extend battery life by roughly 40 percent for longer sessions. Ultra Fast Mode trims animations to speed up the cycle without touching the algorithms or RTP. When I just want the numbers, this switch makes the grind smoother. The slot also brings back Gamble Feature for post-win decisions, which fits the pace of a coin game and adds a small shot of volatility between spins.

Volatility Levels give real control. I can set the game to favour smaller wins that come more often, or go for less frequent but larger payouts. That setting changes the hit profile while keeping the same RTP figure quoted in the sheet. It suits the series because the grid is simple and the risk choice sits with me. Being able to dial it up or down keeps the slot workable across short tests and long sessions.

Buy Feature is there for on-demand bonus access when balance and mood line up. Two clicks and I am into the part I want, which is Hold the Jackpot. Cash Infinity also deserves a nod here. Those symbols can stick on the panel and wait for the feature, then help push towards the top prize. That carry-over behaviour ties the base and bonus together and gives me something to plan around when pacing stakes.

RTP, Volatility and Max Win in 9 Coins Grand Diamond Edition

The published RTP sits at 96.15 percent, which is right in the fair zone for this type of grid. Volatility Levels mean the variance is variable, with a very high profile available if you want the sharp edge. The headline prize is a 5000x bet Grand Jackpot, stated as part of the bonus proposition. The machine runs with nine reels and no lines, and all the heavy lifting comes from features rather than standard line hits.
