SPIES – Operation Fortune: Power Combo Slot Review

Slot Details

SPIES – Operation Fortune: Power Combo is an online slot developed by Infinity Dragon Studios, powered by Microgaming online casinos, scheduled for a release on February 12th 2024.

This is a spy themed slot, from the Power Combo series, which is the 3rd slot from this studio, with the previous 2 being Atlantis Power Combo Slot and Gods & Pyramids Power Combo Slot.

Just like the previous ones, the players will be able to spin the reels for a max prize up to 12,400x the bet.

Slot Design

SPIES – Operation Fortune: Power Combo has a slightly bigger 5×4 gameboard, consisting of 5 reels, 4 rows and 20 fixed paylines.

The slot’s RTP is 96.23%, the volatility is set to MEDIUM and the hit rate is 36.50%.

The minimum bet per spin starts from 0.20$, while the maximum bet reaches 20.00$, making the game ideal for those looking for low wagering slots.

Infinity Dragon Studios are using a bet menu which we like, allowing players to select the desired wager with a single click, but at the same time, giving them the option to adjust it with the plus and minus buttons, as well as the min bet and max bet buttons.

The settings menu is one of the best we’ve seen with options for Quick Spins and Turbo Spins, two separate options for music and sound effects, as well as volume adjuster, rather than just on/off buttons.

The UI is nearly identical to the previous slots from the series, while the symbols are well done, and the animations are superb as usual.

The game has this comic book drawing style, which we are not fans of, but since the studio continues to produce such slots, it must be well received.

Slot Features

  • Wilds: The wilds in this slot substitute for all symbols but scatter symbols, cash and collect symbols.

This symbol shows up quite often and will aid players to complete winnings during base game while waiting for a free spin feature to trigger.

  • Free Spins with Wild Boost: When this feature triggers from the Blue Scatter, the gameboard becomes 5×6 and the paylines increase from 20 to 40. During this feature Wilds are added to the reels for up to 50 spins. Landing another blue scatter will award 1 or 2 extra spins. Landing the Orange and/or Purple scatter may trigger combo feature.

This feature is highly depended on the positioning of the wilds, so sometimes the payouts are really low, like 1x in this instance. During the rest of the triggers we managed to get payouts between 20x and 30x with a few triggers of combo features as well.

  • Free Spins with Instant Collect: During this feature a collect symbol is added to the game that can land only on reel 1. Cash prizes would also appear on reels 2 to 5. Whenever one or more collect symbols land on reel 1, they will collect all cash prizes during that spin on the remaining reels.

During our trigger we managed to get 2 collect symbols at the same time, and a decent cash symbol of 10x with a few smaller ones. The total payout after 5 spins was 51x. This feature can also award bonus symbols which contain one of the 3 prizes Minor 50x, Major 250x and Mega 5,000x. This feature cannot be retriggered or convert into combo feature.

  • Free Spins with Increasing Multiplier: During this feature the player is awarded with 5 free spins and a multiplier starting from 2x that will increase with 1x for spin. Landing a purple scatter will award an additional free spin.

Essentially this feature depends a lot on landing additional free spins, and managing to get winning combinations that will benefit from the multiplier. This was rarely the case, and we understand now why this is the cheapest feature in terms of buying cost.

  • Free Spins Combo: Because of the power combo feature, the free spins can be triggered in combination with 2 or 3 features.

This feature with all 3 bonuses activated has the highest paying potential, as we get double the paylines, extra wilds, a collect symbol with cash prizes and a line win multiplier that increases on each spin. Our total payout was 137.3x which was pretty decent.

  • Diamond Dealer Bonus Feature: Every diamond symbol that lands during base spin, can randomly trigger this feature. The player gets one spin where they can land cash prizes and single or combo free spins.

On our trigger we only received a few cash prizes, but a total payout of 25x which is nice for a single spin.

  • Buy Feature: If the player does not wish to wait for a trigger, they can purchase the features for a calculated cost.

A single feature costs from 30x, two features cost from 45.8x and combining all features will cost 128.3x. The price for Boost is 33.7x, while the price of Collect is 45.8x, and Multiplier is 30x. The combination of Boost & Multiplier is 102.1x, while the combination of Boost & Collect is only 58.7x. The combination of Collect & Multiplier is only 45.8x.


SPIES – Operation Fortune: Power Combo is a decent slot, but adds nothing new and is no different than any of the previous one.

The wagers are identical, the maximum payouts, the free spins features, but with a different skin and feel.

The game will become available on Yukon Gold Casino on February 12th, but we do not expect it to be very popular as if you have played any of other Power Combo slot, this one won’t feel any different.
