About Diamond Trio

As with many Novomatic online slots, the look of this game isn't overly stylish. Don't worry though, as this game really offers substance over style. It's enjoyable to play, plus it offers some really decent prizes. This is the case during the base game, as well as while the fantastic free spins are active.

Some great reasons to play Diamond Trio include:

Diamond Trio is a great slot, and you could win 500,000 coins on just one spin of the reels!

Diamond Trio is a simple slot to play. It has five reels, as is the case with most online video slots, and you'll find just nine paylines. It's possible to adjust the number of paylines to an even lower number, however we wouldn't advise this, as fewer paylines will lead to a much lower chance of you spinning in a winning combination.

But what else is there to say about this online slot from Novomatic? Well, it's worth pointing out that the free spins aren't too exciting, but they do lead to some decent prizes. You should also remember that the RTP of this slot hasn't been made available, so you can't compare its winning potential to other games.

Where To Play Diamond Trio

You can find Diamond Trio at any online casino using software from Novomatic, so you'll have plenty of sites to choose from. To find the best of these sites, just look through the list of Novomatic casinos below, all of which have been reviewed in detail by a member of our expert team.

How We Review

Our review process is a long and comprehensive one, looking at every important aspect of the slot in question. Some important areas we look at include:

Jackpot: It should go without saying that we'll tell you about the jackpot offered at a slot, including how you can win the top prize.

RTP: If available, we'll tell you the exact RTP of a game, so you can understand how much money you can expect to win when you play.

Theme: The theme of a slot might seem unimportant, however we know that it makes a massive difference to your enjoyment, so we'll be sure to tell you about it.

Bonus Features: Some slots have loads of bonus features, others have none. We'll tell you exactly how many the slot in question offers and how they work.

Scatters and Free Spins

The main bonus feature at this slot is free spins, which are activated when you manage to get the three heroines scattered across the reels. You will receive 12 free spins in total, although you can activate more while the feature is active. There are no multipliers when you get winning combinations in the free spins bonus round, but you will activate a free respin when you get two of the heroines anywhere on the reels. These respins happen quite a lot and can lead to big wins.

Graphics and Design

There's no other way of saying it: the graphics at Diamond Trio are pretty basic and don't compare favorably to the graphics of more modern online slot games. The symbols are simply drawn, and the whole idea of making the slot look like a land-based machine is now pretty dated. Don't worry though, as the low-quality graphics don't affect the amount of enjoyment you'll experience when you spin the reels.

Payouts and Prizes

The most that can be won when you play Diamond Trio is 500,000 coins, which makes this online slot one of the most generous around. You will win this jackpot when you manage to get five diamond symbols across an active payline. Other symbols that offer big prizes include the sports car, the files and the guns. You should also remember that this slot has a gamble feature, so you'll always have the chance to double the amount of money you've won. Only the bravest of players will risk their cash in this gamble though! There is no RTP available for this online slot, which is something we think Novomatic should remedy soon.

Play on Mobile

If you own a mobile device, you'll certainly be able to play Diamond Trio on it. This is the case regardless of whether you own an iPhone smartphone, an iPad tablet, or any other mobile device with a touchscreen. All you'll need to play is an internet connection, plus you won't usually need to download anything. Playing slots on a mobile device really is an incredibly simple experience!

Just open your browser, head to your favorite online casino and select the slot you want to play. Novomatic's games are made with special HTML5 technologies that allow you to run games on multiple devices. The games are optimized to fit all screens, so you can enjoy Diamond Trio wherever you go.

Many people are concerned about playing online slots using their smartphone or tablet as they don't want to use up all their data. This shouldn't happen though, as slots don't use loads of data when they are played. If you're still concerned, we'd recommend hooking up to a WiFi network while you're out, and these can be found pretty much everywhere nowadays.
