Book Of Spies Mission X Slot Review – Nolimit City

It has only been around a week since my last Nolimit City slot review, which is titled ‘Monkey’s Gold xPays’. This slot really impressed me with a great selection of unique features and high variance with a max win of over 12,000x. Today we have the studios latest slot release! This slot is titled ‘Book Of Spies Mission X‘. Which is available to play now across all sites.

This slot has a theme based on secret agents and spies on their latest mission. The majority of the slot background is blurred / out of focus to see any real detail. Close up in the slot background you can see a pistol with a bullet, a tech screen, and binoculars. It is a shame most of the slot background is not visible but I do like the art style of the objects and symbols which can be seen. I was expecting more from Nolimit City, the studio’s past games have shocked with details and unique artwork.

Book Of Spies Mission X has a setup of 5 reels by 4 rows, this includes 1,024 – 16,807 set pay lines. This slot is high variance with a set RTP of 96.09% and max win capped at 27,000x. You can bet from £0.20 – £100.

Book Of Spies Mission X Features

Landing 3 scatters on reels 1, 3, and 5 simultaneously during one base game spin will trigger the ‘Secret Agent Free Spins‘ feature. This bonus feature can be bought for 70x your stake if allowed in your country. The number of free spins awarded is the number of nudges required to move the scatters to the bottom position on the reels. The number of free spins possible ranges from 3 to 21 spins. Before spins begin one of the 4 premium symbols is randomly selected to be a special symbols for the duration of the feature. If 3 or more of the special symbols land during a free spin, the symbols will expand to cover the reels. Expanded symbols pay anywhere on the reel set, this feature cannot be retriggered.


Overall, I think Nolimit City surprised me within the visuals and high variance. However, let me down with the visual aspects not showing details or a unique art style. I liked playing the slot for myself and enjoyed the free spins feature. Be sure to try out the slot for yourself if you haven’t already. Also, be sure to check out our exclusive casino offers.
