Double Diamond Slot Review

The Double Diamond slot is one of the old school classic slots from IGT that was designed for land-based casinos. The game is now available online and those who’ve enjoyed spinning it at Vegas can now give it a spin at home. A simple 3 reel, 1 payline game, the Double Diamond slot machine doesn’t offer much in terms of special features. The excitement is all in the traditional gameplay of lining up 3 matching symbols and winning potentially up to 1,000x your bet size.

Look and Feel

Staying true to its old school roots, the Double Diamond slot game will remind you of vintage fruit machines. The online slot sports an intricate purple frame against a black background with thick, wide reels where the symbols take center stage. Nothing too spectacular in terms of sound and you will have the familiar electric beeps and boops of slot machines in the background. Unlike a lot of other classic slots, the layout in the Double Diamond slot game remains clean and uncluttered. This feels like a solid slot in every sense of the word.

How to Play

Double Diamond takes the most basic of slot forms. This 3 reel, 1 payline game is as simple as it gets. You only have 1 payline, so there’s really not much to consider here. Decide how many coins you want to bet. Minimum bet per spin starts at 100 coins and hits a maximum at 10,000 coins. 

Generally speaking, you just need 3 matching symbols on the payline in the middle to win. The Cherry is however the exception and it will payout even when you just have 1 or 2 of them. Obviously, some symbols will pay more than others.

Symbols in Double Diamond

Starting from the highest value, the symbols in Double Diamond are below:

·      Double Diamond logo

·      7

·      Triple Bar

·      Double Bar

·      Bar

·      Cherry

·      Any combination of Bars

The Double Diamond is the highest paying symbol and when involved with other symbols in a winning payline can offer some serious wins.

Special Features and Bonuses

There aren’t really special features in the Double Diamond slot, but there are two symbols that work a bit differently from the others:

Double Diamond: The highest paying symbol of them all, the Double Diamond game logo can also boost your line wins. When there is 1 Double Diamond in a payline, it will multiply your regular win by 2x, and when there are 2 of them, then you will see a 4x multiplier. You will however have to get symbols on the payline itself and a Double Diamond on its own will deliver nothing.

Cherry: While other symbols will require 3 of a kind to payout, the Cherry can match up with any of the other symbols. The wins are however much smaller than the Double Diamond. 2 Cherries will get you 5x your bet, while 1 will get you 2x your bet.

Double Diamond Compared to Other Slots

There are quite a few classic slots out there. Blue Diamond is a good choice if you enjoy the Double Diamond slot. The look and feel of the two games is fairly similar with just 3 reels and 1 payline, however Blue Diamond has a Wild Re-spin feature via the Blue Diamond symbol. It’s exactly as it sounds. The Blue Diamond symbol works as a Wild, and it will give you a re-spin

Realistic Games has also released a couple of games like Sunset Reels that have the same simple look as Double Diamond. Sunset Reels is also a 3 reel, 3 row game, so it manages to stuff in 5 paylines instead of just 1. However, we do find the Double Diamond gameplay to be more exciting with the potential for a multiplier when you hit the Double Diamond symbol.

Double Diamond Fairness

The RTP for the Double Diamond slot machine is around 95% and most players have found this to be a medium to high volatility slot. In plain English, don’t go in expecting frequent wins here, but you could potentially be rewarded by more than decent payouts if you manage to hold on. This is one of IGT’s most popular slot machines in land-based casinos and has been tried and tested by numerous gamblers over the years.

Tips for Double Diamond

Without the Double Diamond symbol, payouts are pretty average, so you want to keep your fingers crossed for that symbol because it can really jack up the payouts you see. What else can you do beyond that? You may want to consider playing this game with a casino bonus first. The minimum bet isn’t cheap, and since it can take a while before you hit the higher paying symbols or a combination with a Double Diamond, some bonus chips will help you get a feel for the game before you decide to double down on this one.

Hype or Not?

This is probably not a game we would suggest for beginners, but experienced gamblers love Double Diamond. It’s kind of a slot for purists. There are no special features or crazy animations and the excitement is all about lining up the symbols, with the hope of a Double Diamond that will act as a multiplier for bigger wins.


The Double Diamond slot machine is what we call a slot with an edge. It all looks quite simple with its 3 reels and 1 payline, and even the payouts are fairly average. That is until you start getting the Double Diamond symbol on your payline which can act as a 2x or 4x multiplier. This is not going to be a game for everyone, but if you’re looking for something old school that can get your heart pumping, check Double Diamond out at one of the online casinos recommended here.
