9 Coins™ Grand Diamond Edition Slot Review

Multiple igaming awards nominations for 9 Coins Grand Diamond Edition

9 Coins Grand Diamond Edition stands out straight away because it has been nominated for major igaming awards. It went up for Online Game of the Year at the Balkan Entertainment & Gaming Expo Awards 2023 and Online Slot of the Year at the Global Gaming Awards EMEA 2024. As someone who spends a lot of time on new releases, I can see how its engaging features and sharp presentation pushed it into that conversation.

On the reels, the slot feels like a dazzling extension of the player-favourite 9 Coins series. The graphics are sleek, and the whole setup focuses on engaging features rather than standard line wins. From my sessions, the mix of Hold the Jackpot action, flexible volatility and cash features gives a complete gameplay experience that feels tuned for players who enjoy high-impact moments.

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

The wider Coins series, including 9 Coins Grand Diamond Edition, has been nominated at the CasinoBeats Game Developer Awards 2024 for Game Mechanic of the Year and Game Feature of the Year. That says a lot about the unique math model. This instalment expands and improves the most popular elements, and from my point of view the series has grown into a reliable choice whenever I want coin-based action and steady entertainment.

Game Info for 9 Coins Grand Diamond Edition

9 Coins Grand Diamond Edition is a slot from Wazdan with 9 reels and no traditional paylines. Everything centres around coin positions and feature triggers rather than line hits, which fits the treasure theme of the game. It is part of the Coins series and landed in October 2023, so the interface feels modern, with clean menus and smooth performance across devices during my playtests.

The stated RTP is 96.15%, which sits in a fair range for online slots. Volatility is tagged as very high, but thanks to Volatility Levels I can adjust the profile, moving between more frequent smaller hits or rarer larger swings. Max win reaches 5000x bet, aligned with the Grand Jackpot in the bonus. Bets start from 0.20 and can climb to very high stakes, so bankrolls of different sizes fit in.

Features in 9 Coins Grand Diamond Edition

Feature-wise, 9 Coins Grand Diamond Edition packs a lot in. Chance Level lets me multiply my stake up to 10x to raise the odds of triggering the Hold the Jackpot bonus round. Cash Out adds another layer in the base game, as a labelled position collects values from Bonus symbols and pays a percentage after a fixed number of spins, which keeps some interest ticking over even when the main bonus is not landing.

Cash Infinity is a familiar element from the series, and here those symbols stick to the reels until the end of the Hold the Jackpot bonus game. From a player angle, that stickiness lifts the tension when I am chasing the Grand Jackpot, because I know those values are locked in. On top of that, there is a standard Gamble feature for double-or-nothing shots after wins, which I use sparingly due to the already high variance.

Around the edges, Wazdan layers in its usual quality-of-life options. Energy Saving Mode helps on mobile when I am not plugged in, while Ultra Fast Mode speeds up the reel cycle if I want less animation and more pure action. Volatility Levels and the Buy Feature round it off: I can tailor hit frequency and, if I feel like it, pay to jump straight into the most exciting part of the game.

9 Coins Grand Diamond Edition Symbols and Paytable

The symbols in 9 Coins Grand Diamond Edition stick closely to the series identity. The grid is populated by coins rather than regular card ranks or themed icons, and Clash of Slots simply lists them as Special and Multiplier. In practice, that means the paytable is built around fixed values and special functions on these coins, instead of classic line-based payouts. Wins come from the features, not strings of matching pictures.

Bonus symbols carry cash amounts that feed into Cash Out in the base game and become the focus during Hold the Jackpot. Cash Infinity symbols, flagged as special, stay glued to the reels until the feature ends, which changes the effective value of positions on the screen. Multiplier symbols, as the name suggests, improve returns on collected coins. I like this stripped-down paytable, because it keeps the focus on features and coin values.

Hold the Jackpot Bonus game in 9 Coins Grand Diamond Edition

Hold the Jackpot is the core bonus game in 9 Coins Grand Diamond Edition and a staple of the series. Once triggered, the whole tone of the slot shifts up a gear. Coin symbols take centre stage, and I am effectively hunting for enough values and special coins to climb towards the Grand Jackpot. The description from Wazdan calls it a highly satisfying bonus game with generous prizes, and that matches my own runs with it.

What I enjoy most here is the sense of progression. Cash Infinity symbols that landed earlier stay put, so going into Hold the Jackpot with several of them already in place feels exciting. The bonus round piles on tension as more coins land, filling positions and edging the total closer to those bigger payouts. Even when I fall short of the maximum, the feature often pulls a session back from a cold spell.

Chance Level plays a real role in how often I see Hold the Jackpot. When I bump Chance Level up, I notice more frequent entries into the bonus, at the cost of a higher stake per spin. From a seasoned player view, that trade-off makes sense if I am specifically chasing feature-driven sessions. When the Grand Jackpot of up to 5000x bet finally drops, it feels like the whole structure of the slot has been geared towards that moment.

Assets for 9 Coins Grand Diamond Edition

From a practical point of view, 9 Coins Grand Diamond Edition is widely supported: it runs on all major platforms, in over 30 languages and with all common currencies, so I have had no trouble loading it on different devices. With the combination of strong coin mechanics, Chance Level, Cash Out and Hold the Jackpot, this has become one of my regular picks when I want a high-volatility coin slot with serious feature play.
