  • The autoplay feature allows you to spin the reels an infinite amount of times.

Design and Audio Effects

As expected, Book of Spies: Mission X Slot is a good-looking slot that takes place on the rooftops of an unnamed city with spotlights hovering in the background. The grid looks like a piece of spy-tech and often switches between a variety of color schemes, depending on the game.

The soundtrack and audio effects are phenomenal, as they incorporate a variety of elements taken from classic espionage films. When the reels are spun, the sound of “hacking” can be heard, followed by thuds when landing on a win. It also becomes much more intense when the bonus round is accessed.


The bonus features that are used in this slot are unique as you’re able to take advantage of a variety of multipliers and special symbols, such as the xWays symbol that increases the number of winning patterns that you get by providing more of the same symbol in the form of a stack.

The xNudge symbol provides you with a multiplier up to 21x your bet. There’s also a bonus round that you can buy into at any time. This doesn’t guarantee a win, but if you do, you could walk away with huge profits.


Book of Spies: Mission X Slot is a game that takes some time to get used to as it’s incredibly quick-paced. However, there are enough features to keep you entertained, and one of the best bonus features that are offered is easily accessible, albeit for a hefty premium. The theme of this game is shared with other variants, but this is one of the best-looking slots of the spy genre, and the xWays and xNudge mechanics make for a pleasant online betting experience.

This is a slot that we’ll recommend to anyone looking for something unique, and to those that are fond of the genre.
