Shadow Diamond Slot Machine

The Shadow Diamond is one of the first in a range of games that Bally produced, taking them away from their classic format and into a totally new world. It is much more modern than most of the classic Bally slots, with some great features.

As soon as you start to play Shadow Diamond, it doesn't really look or feel like a Bally game. I'd say it has more of an IGT feel to it — you know, the IGT games with the stacked Wilds where you can fill a screen with the same symbol.

The theme to this game is a diamond that has been inherited — worth a fortune, apparently. I didn't get that from the game by the way, I read it on a marketing flyer I found when I was out and about. I'm not quite sure how that story fits into the gameplay, but there you go. Onto the game itself.

Shadow Diamond Bonus

There is only one bonus in Shadow Diamond and it takes place in the form of free spins. You get 7 free spins in the bonus, which is not many, but you have an increased chance of winning big.

The bonus gives you extra chances to win, with mystery symbols that reveal themselves as high-scoring symbols once a spin is over. It's kind of difficult to explain how this works, so the best thing to do is play it and see.

The good news is, we have a free version to play here — no need to play for cash, no cash involved, just fun play, so you can keep going as long as you want without having to wager a dime.

If you do want to gamble, then I would recommend you visit our real money casinos page — there you will find the best casinos to play cash games. All of the casinos listed offer great welcome bonuses and also pay out winnings quickly — a vital factor when it comes to real cash gambling.

Shadow Diamond has some nice touches when you play. When you get the same stacked symbol on the first three reels, the picture it creates kind of leaps out towards you. It's almost like completing a jigsaw puzzle in some ways — you get all the pieces in place and then you get to see the final picture in all its glory.

The sound effects and graphics of Shadow Diamond are pretty cool and it will be interesting to see how popular it is in Vegas over the longer term — will it truly stand the test of time, or are these games a flash in the pan?

Frequently Asked Questions

What is the RTP of Shadow Diamond slots?

Bally has not publicly disclosed a specific RTP (Return to Player) for Shadow Diamond slots. As a land-based Bally title, the theoretical return is configured by individual casinos. The mystery symbol mechanic during the 7-spin free games feature — where symbols reveal themselves as high-value icons after each spin — is the game's primary driver of above-average session returns.

Can I play Shadow Diamond slots for real money online?

Shadow Diamond real money slots are available at online casinos carrying the Bally/SG Gaming library in regulated markets including the UK. The stacked Wild mechanic and mystery symbol free spins translate well to online play, making it a worthwhile real money option for fans of the Bally style. US and Canadian players are generally limited to land-based casino play for this title.

What makes Shadow Diamond different from classic Bally slots?

Shadow Diamond represents a significant departure from Bally's traditional slot format. Rather than the simple payline mechanics of classic Bally machines, Shadow Diamond incorporates a stacked Wild system — where the same symbol can fill multiple positions on a reel simultaneously — that is much more characteristic of IGT's design philosophy. This shift in approach was part of Bally's broader move towards modern video slot mechanics in their newer releases.

How does the stacked symbol feature work in Shadow Diamond?

Shadow Diamond's stacked symbol mechanic allows the same symbol to appear in multiple consecutive positions within a single reel column. When matching stacked symbols align across the first three reels, the visual effect is a large unified image that "leaps out" towards the player — creating a satisfying near-cinematic moment before the full win is calculated. This visual presentation is cited as one of the game's most distinctive features.

What is the mystery symbol feature during Shadow Diamond free spins?

During the 7 free spins in Shadow Diamond, mystery symbols appear on the reels during each spin. Rather than showing their true identity while the reels are spinning, these symbols are only revealed as specific high-value icons once the spin comes to rest. This delayed reveal creates ongoing tension throughout the free spins — you won't know the value of each mystery symbol until the exact moment the reels stop, which can turn an apparently modest spin into a significant win.

Is Shadow Diamond similar to other games in the new Bally range?

Shadow Diamond was among the early titles in Bally's modernised game range that moved away from their classic format. Other titles in this new generation of Bally games share similar characteristics — stacked Wilds, more elaborate bonus mechanics and improved visual presentation compared to the traditional Bally catalogue. Players who enjoy Shadow Diamond will likely find other Bally titles from the same period similarly appealing, including games like Lucky Tree and Moon Goddess that use comparable stacked symbol approaches.
