Load up your revolvers and grab your sharpest suit because it’s time to go deep undercover at top slot sites in the SPIES – Operation Fortune: Power Combo slot from Games Global studio partner Infinity Dragon Studios. In this stylish adventure, players must choose which side to join forces with before heading out on a mission to win up to 12,400x their stake. Join me as I suit up to find out more in this SPIES – Operation Fortune: Power Combo slot review.


Visually, the SPIES – Operation Fortune: Power Combo slot game is a bit of a mixed bag. There are elements of the design I really liked, with the characters having quite whacky designs and there being some really fun little sequences.
However, the game also felt a little dated and reminded me of some older titles from the likes of Microgaming and NetEnt, with the reel design being very basic. The game is set inside some sort of studio or operations center, with a vault to the side of the screen and various radars and news tickers in the background.
At the start of the game, you choose between a male and female spy, and your choice will then appear on the reels in the game, while the three villains all sit above the reels throughout.
The betting range in the version I tested for this review is $0.20 up to $20, which is quite limited compared to other top online slots.
SPIES – Operation Fortune: Power Combo has a simple base-game set-up. The slot uses five reels and four rows, offering 20 fixed paylines for players to win. However, this can be increased during the bonus rounds, with the Wild Boost enabling six reels, five rows, and up to 40 paylines a spin.
The control panel for the game is underneath the grid, with players able to set the autospin, speed things up with the turbo spin, adjust the stake, and, of course, check the paytable. Players also have the ability to switch spies from the information menu at any point in the game.
Much of the action in SPIES – Operation Fortune: Power Combo is geared around the slot’s free spins bonuses. There are three different free spin rounds, and they are triggered based on which Scatters are revealed by the Green Radar. You will need to land three Scatters to launch the round. The three bonuses are as follows:
As I have already mentioned, it is possible to trigger one bonus during another, combining the features and boosting the winning potential.
It is not just the Scatter that can lead to some big wins. There is also the Diamond Dealer bonus. Diamonds are collected whenever they land and can trigger this bonus on any spin. You will get one free spin, and if one Scatter lands, it will trigger its corresponding bonus.
The slot comes with a selection of Buy Bonus slots options. Players can purchase different variations of the free spins round, with the cheapest option being the Increasing Multiplier bonus for 30x your stake and the most expensive being all three bonuses together for 128x your stake.
For this SPIES – Operation Fortune: Power Combo slot review, I tested the game on a desktop and mobile device, running it on Google Chrome and Safari, respectively. The experience remained the same on both devices, with the mobile versions being just as easy to play thanks to the uncluttered game screen and simple controls.
The betting range in the version I tested for this review is $0.20 up to $20, which is quite limited compared to other top online slots.
If you want to try the game before you play for real money, I recommend trying the demo version we have provided. This will allow you to explore the game’s bonuses and adjust to some of its mechanics. The demo is supported across desktop and mobile devices.
The SPIES – Operation Fortune: Power Combo’s biggest win is 12,400x your stake, which is an attractive amount, even with the lower betting range. The RTP is 96.23%, which puts it above the industry average. It is medium volatility, which I found reflected my experience of playing, with a mixture of wins being paid out.
SPIES – Operation Fortune: Power Combo, while not without its flaws, is a fun online slot that makes good use of its bonus features. The ability to combine the bonus rounds can lead to some really exciting sequences and can also provide some good winning potential.
From a visual perspective, the game could improve, and the low stakes may not be for everyone, but if you have no issues with either of these things, then this is a spy adventure I am happy to recommend going on.
If you enjoy SPIES – Operation Fortune: Power Combo, then you should check out other titles from Infinity Studios featured in legit online casinos.
