Who says all the spies have to be male? There’s no James Bond, in this case, folks, rather, we’re looking at something similar to Charlie’s Angels when we meet the Diamond Trio, which just so happens to be the title of this online video slot from Novomatic. 3 women who are hot on the trail of a mysterious diamond thief. They need all the help they can get, and in return, there are some big prizes to be won as a reward!

Gameplay and Symbols

We’d like you to meet with Flame, Tegan, and Chloe, the Diamond Trio who are determined to find the diamonds which have been snatched. The design of this slot game is quite impressive, with the control buttons being underneath the reels. It seems like one of those slot machines one can find in pubs, amusement arcades, and clubs. Further good news is that it is available for playing on your mobile devices, instead of just on your PC.

It has 5 reels and 3 rows of symbols, as well as a total of 9 paylines which will hopefully grant you lots of winning combos. Those paylines aren’t a fixed lot, meaning you have 2 decisions to make before you can start spinning the reels. You need to decide on your number of paylines activated, and also your bet. The minimum cost when it comes to playing “Diamond Trio” with all of the paylines enabled is 1 coin and the maximum is 100. The ‘Jackpot’ here amounts to a hefty 5,000 coins.

Getting back to our lovely agents, Tegan is the blonde of the group, while Chloe is the brunette, and Flame happens to be a fiery redhead (hence the name). They form 3 of the symbols in this online slot, while the other symbols are a top-secret file, a red Ferrari, a priceless-looking diamond. Then we get one with the Diamond Trio sitting comfortably in a car, and another one has a gun, of all things, in a holster on the agent’s attractive-looking leg. Then we have the 10 – Ace low-value playing card symbols.

Re-Spins and Gambles

Sadly, there isn’t a Wild in this slot. Instead, you get a special feature where if you land 2 of the Diamond Trio on your reels, you will be awarded a free re-spin of those reels, which offers you the chance to land all 3 of the Dimond Trio. Trust us, you want that, since, if all 3 members of this Trio appear at once, you would be granted 12 free spins.

Furthermore, any wins the player gets during these spins would be doubled! It’s even possible to re-trigger them, assuming the trio makes yet another appearance. If they do, 12 more free spins plus doubled wins would once again grace your screen.

It’s always a good idea to check the paytable, which is filled with useful info, such as, for instance, the fact that 5 of those diamond symbols on an enabled payline get you 5,000x your bet. It’s 2,000x for 5 red Ferraris, while you’d get 750x for 4 of those gun holster symbols.

This slot also offers a Gamble feature, which pops up after you end up with a win during the base game. Here, the task (if you decide to take on this challenge in the first place), is to correctly predict whether the playing card will be black or red. Getting it right doubles your win, plus you have 4 more chances to gain even more wins. But take heed, as one wrong choice means you lose that precious win!

Final Verdict

Quite a fun and enjoyable online video slot from Novomatic. That re-spin feature will surely have any player on the edge of their seats, and that bonus round offered here can be really lucrative as well. Just make sure to be extra careful with the Gamble feature, and you should be fine. If you feel this action-packed and sexy theme is something up your alley, then all you need to do is give it a spin or two on one of our top-rated online casinos. Nothing left for us to do but to wish you tons of luck!
