9 Coins Grand Diamond Details, RTP and Volatility

This latest edition to Wazdan’s 9 Coins series has a familiar look and feel to its predecessors. However, it also sees the addition of two new bonuses, Cash Out and Chance Level, plus a significantly higher max win of 5,000x.

The game features nine individual reels set in a 3x3 grid layout. Unlike most online slots, there are no regular symbols spinning on the reels, nor traditional paylines. Instead, only bonus symbols appear. You can still win in the base game, though, thanks to the innovative Cash Out feature. We’ll explain this fully later in our 9 Coins Grand Diamond review.

An RTP of 96.15% is slightly above the industry’s average mark. This is coupled with an adjustable variance level, which you may set to suit your own needs. Here, three volatility options range from low to high. Finally, a fairly standard range of bet limits starts from $0.10, rising to $100 per spin. 

Theme & Graphics in 9 Coins Grand Diamond

True to form, the 9 Coins Grand Diamond slot grid is surrounded by what appears to be a mystical cosmos. The soundtrack is a relaxed affair, while primary colors of red, blue and gold dominate this treasure-themed slot. 

Even though there are no regular symbols spinning on the reels, there are plenty of bonuses to look out for. These include gold coins, red infinity coins, the collector, mystery and jackpot mystery symbols, as well as mini, minor and major jackpot symbols. Each symbol is beautifully designed, with a nod to the Far East.

9 Coins Grand Diamond Slot Features

The following sections of our 9 Coins Grand Diamond review will focus on the various features of this Wadan release.     

Regular Symbols

As previously mentioned, you won’t find any traditional symbols, like fruit or bells, on the 9 Coins Grand Diamond slot reels. However, there are plenty of special symbols which trigger features and award prizes.

Cash Symbols

The closest things to a regular symbol in this slot are the gold coins containing monetary values, dubbed “cash symbols” by the developer. During the base game, these award cash prizes ranging from 1x to 10x the bet, but only when landing on a Cash Out space.

Cash Out

The Cash Out label may randomly attach itself to any of the nine reels during the base game. It accumulates values from any bonus symbol landing on it for up to 20 spins. The final spin reveals a randomly-selected percentage, ranging from 10% to 200%, which is applied to the total value of all bonus symbols collected. 

Cash Infinity Symbols

Red Cash Infinity symbols may appear at random, but will not payout until the end of the bonus game. These coins are sticky and remain locked in position while the other reels spin. If drawn on the middle reels during the base game, the chance of triggering the bonus game is increased.

Jackpot Symbols

Should the Mini, Minor or Major symbols appear on the reels, you’ll win 10x, 20x or 50x you bet. However, you won’t see these during the base is possible to collect multiple jackpots at the same time.

Mystery and Mystery Jackpot Symbols

A Mystery symbol will randomly transform into any other bonus symbol, except for Cash Infinity coins. Mystery Jackpot symbols behave similarly, only they’ll turn into Mini, Minor or Major Jackpot symbols, specifically.

Collector Symbols

This red treasure chest symbol is responsible for gathering up all values displayed on the Cash and Cash Infinity symbols. This figure is then multiplied by a random value of between 1x and 20x.

Hold the Jackpot 

Drawing any three bonus symbols of the same type on the middle reels triggers the Hold the Jackpot bonus game. Here, three respins are initially awarded, which resets with every subsequent bonus symbol that lands. 

Multiple jackpots of the same type can be rewarded during this bonus. Fill all nine reels with bonus symbols to receive the Grand Jackpot of 5,000x the bet.

9 Coins Grand Diamond Review – Our Final Verdict

Appearances can be deceiving, and that’s certainly true of this slot. Although it looks quite similar to its predecessors, Wazdan includes a number of innovative features we’ve not seen before. What’s more, the maximum possible payout has been bumped to a healthy 5,000x, double that of 2023’s 9 Coins Grand Platinum edition.

We particularly liked the random Cash Out element of the base game, as this can quickly rack up the rewards. However, we’re not sure that everyone will enjoy this. It's possible to receive just 10% of what you collect, which feels disappointing when it happens.

Although the customizable volatility, solid RTP and wide range of betting limits suit all players, we’re not sure this is a slot for beginners. It took a lot longer than usual to understand the game’s mechanics, despite being experienced players. However, it’s worth sticking to the task, as 9 Coins Grand Diamond is actually quite enjoyable once you figure it out.
