Will you make the grade as the ultimate female spy? Take a look at our review of Diamond Trio by Novomatic and discover the delights for yourself.

Classic Play

Despite the thoroughly modern theme, the graphics on the reels in Diamond Trio are fairly dated compared to other titles in the market. They’re neither particularly realistic nor cartoon-themed, leaving them in a dull, 2D area.

Teagan, Flame and Chloe are the three stars of the show, the blonde, redhead and brunette respectively and other than their stunning looks, they’ve got a range of other accessories at their disposal. Top secret documents, fast cars and a sexy thigh holster are just some of the symbols you’ll be playing with, along with the diamonds that you’re trying to save.

However, although the symbols aren’t anything fantastic, the design of the buttons to the gameboard is quite fun. Creating an almost 3D effect, the buttons are designed to look as if you’re playing on a land machine so it’s not difficult to imagine yourself in a casino.

This layout is different from some of the other Novomatic titles that you may have played such as American Gangster or Fruit Fest. Rather than using plus and minus arrows to select your betting levels, you need to click the button of your choice.

Girlie Glamour

The three girl spies don’t just kick serious butt, they look great too and when it comes to handing out rewards for giving them a hand, they’re pretty generous.

If you match three of them on the reels you’ll get 12 free spins, a bonus which can be re triggered providing the chance for a big win. In some cases these free spins can almost seem to be never ending as it’s not that difficult to retrigger them again during the bonus turns.

If one of the three girls is still off on a mission and doesn’t quite make it to the reels in time and you just land two instead, you’ll have the chance to spin again for free. Just a single turn, this gives you one more chance to get the trio together and win 12 free spins.

Top Prizes

Diamond Trio is played on 5 reels and on up to 9 paylines. You can choose to reduce this if you prefer, using the buttons on the front of the reels.

The coin value can be adjusted between 0.5 and 2.00 per line, with up to 100 bet per line, giving a max bet of 900 for all lines in play. This is a good game for offering choices which suit both low and high rollers, accommodating all kinds of betters.

The prizes on offer are good with a top win of 5,000 for matching five of the diamonds along an active payline. For this symbol, the payouts start for a match of just two but all other symbols require a match of at least three.

If you are willing to take a bit of a chance, there’s always the Gamble feature which seasoned Novomatic players will be very familiar with. It’s presented in the same format here, with a card game deciding whether you win or lose.

For those who haven’t played before, there’s the chance of doubling your money if you correctly guess whether the next card to be turned over will be red or black. If you lose, you’ll forfeit the prize you just won on the reels and will be returned back to the main game. Winners can opt to repeat the gamble but how long will you hold your nerve for….?

Fighting Fit Females

Diamond Trio by Novomatic is a fairly formulaic online video slot which doesn’t offer a lot of new features or extras. There’s no bonuses for the game, and no wilds or multipliers either leaving it feeling rather sparse. The respins win is useful and can often be easily retriggered, and this would be the main reason to try out this game.
