Overview of the Double Diamond slot game

Do you like retro old school slots? If so, you are going to really like the Double Diamond slot machine. This is how the old conventional slot machines used to be and many people loved to play them. The online version has been a big hit with players who are happy with the simplicity of the gameplay.

There is nothing at all complicated about the Double Diamond slot from IGT. It offers you 3 reels and a single payline. With some 5 reels slots everything is too complicated and it can be easy to miss opportunities for wins.

Each time you spin the reels with Double Diamond you can place a minimum bet of 10 and a maximum bet of 3,000 which is quite a considerable range. The slot has an RTP (return to player) of 95.44% which is better than the average of 95%.

The symbols used in Double Diamond are truly classic. You get cherries, bars of 2 different colors, red number 7s and the double diamond special symbol which is wild. As there is only one payline, you will never be in any doubt if you have matched symbols to win or not.

With the cherries you only need one of these to appear on your reels for a 2 times multiplier. If you get 2 cherries on your reels then you get a 5 times multiplier. For matching 3 cherries you will receive a 10 times multiplier.

There are 2 different color bars with the Double Diamond slot from IGT. These are blue and purple. If you are able to get any combination of the bars on your payline then you will get a 5 times multiplier.

When you are able to land 3 blue color bars on your payline you will receive a 10 times multiplier. There are 2 different versions of the purple color bar. One has two bars and the other has three bars. Get 3 of the two purple bars on your payline and you win a 25 times multiplier. With 3 of the three purple bars you get a 40 times multiplier.

Next highest payout comes from the red number 7s. If you can get 3 of these on your payline then you will be awarded with an 80 times multiplier. At the top of the payout tree is the double diamond special symbol. If you are lucky enough to get 3 of these on your payline then the multiplier is an incredible 1,000 times.

The double diamond special symbol is also wild and it will substitute for any of the other symbols used in the slot game. These symbols appear pretty often on your payline so there is always a good chance that you will win with this as a wild. If you get a single double diamond symbol then this doubles your win and 2 of them will quadruple your win.

You can use the single spin button to play the slot on a manual basis. There is also a button for “autoplay” which saves you having to click the button all of the time. With the autoplay button you can get the slot machine reels to spin automatically 10 times or even 50 times. Be careful of this feature as it is easy to get distracted with it.

You are going to find that sometimes symbols do not appear directly on the payline but just above it or below it. This is not a winning situation and some players don’t like this.

Bonus rounds at Double Diamond casino game

The Double Diamond slot machine from IGT does not have any special bonus features or bonus rounds. All of your big wins will come from landing the large multiplier combination of symbols such as the number 7s and the special double diamond symbols.

A lot of online slot players really enjoy playing the bonus features and if you are the same then you should probably give IGT’s Double Diamond a miss as it will be too simplistic for you. If bonus features are your thing, then give the Goldfish slot from WMS a try instead of the Double Diamond slot.

Simplicity is what the IGT Double Diamond slot is all about. It really resembles some of the earliest conventional slot machines and this is how IGT designed it. If you want more complex features then you will need to look elsewhere.
