The life of a spy is a mysterious one, and no matter if you’re a James Bond or more of a Johnny English, Book of Spies Mission X Slot might be the game for you.
Spearhead Studios are the Casino Software Provider behind the game, and they’ve teamed up with NoLimit City to bring the brilliant xNudge and xWays features to life yet again.

As you’ve probably guessed by the title, Book of Spies Mission X Slot, the immensely popular ‘Book of’ style of gameplay is present here too, and it’ll be interesting to see how they work in harmony.

International Espionage

Lara Jones is an intrepid heroin leading a group of Secret Agents on what’s been described as an impossible mission to hack the vaults of an evil spy master where they’ll attempt to steal the Book of Spies itself.

Aid her in this quest, and hopefully you’ll line your pockets along the way. The theme and visuals for the game leaves a great first impression.

Situated atop a high building, binoculars, a gun and a hacking device lay on the balcony with spotlights and a cityscape visible in the background. The music is dramatic and suspicious in nature, and indicative that something big is about to go down.

The Base Game and Features

Book of Spies Mission X Slot is a 5×4 slot with a ways to win mechanic. This means that symbols will connect regardless of position on the reel, as long as they connect consecutively from the left most reel and 3 or more symbols are present.

Ways to win is an increasingly popular mechanic that seems to be popping up everywhere. It ignores the traditional paylines that you might see from more classic games and hits more regularly due to the lack of restriction on where the symbol needs to sit on the reel.

The default number of ways to win on Book of Spies Mission X Slot on any given spin is 1024, but this can increase with the help of NoLimit City’s xWays mechanic.

xWays Mystery Symbol

A mystery symbol can hold 2 to 4 of the same symbol inside it, and will expand the reel up to a potentially 7 high configuration, increasing the number of ways to win.

In the Base game, this may appear on reels 1, 3 and 5, and all of the reels in Free Spins.

The maximum possible ways to win in the Base Game on Book of Spies Mission X Slot is 5,488, but this can rise exponentially in the Free Spins to 16,807 ways.

This helps massively in getting those wins connected, and making them bigger in general. All xWays on a panel will reveal the same symbol. Book of Spies Mission X also utilises another well known and popular NoLimit City Feature called xNudge.

XNudge Multiplying Wilds

Expanding Wild Symbols exist on reels 2 and 3, and if present, it will always nudge up to become fully in view.

Each Nudge upwards will increase the multiplier by +1 up to a maximum of 4x. Two of these that land on the bottom of their respective reels will net you a maximum Base Game multiplier of 8x.

Scatters may land and be subsequently covered by the xNudge Wild, but it will shine through and still count if enough Scatters exist to trigger the Free Spins.

Secret Agent Free Spins

Secret Agent Free Spins will trigger if at least 3 Scatter Symbols land anywhere in view. The amount of spins you get will determine on where it landed on the reel.

Each Scatter Symbol will nudge downwards, granting 1+ spins for each nudge, until it reaches the bottom of the reel.

Before the Casino Bonus starts, one symbol will be selected to become the ‘target’ or special symbol, introducing that ‘Book of’ style of gameplay we mentioned earlier.

If 3 or more reels contain at least one instance of the symbol, then they’ll turn into a stacked symbol and a pay anywhere mechanic will come into play, rewarding you depending on the number of stacked symbols you’ve obtained.

There’s a couple of other differences too.

In Free spins, each nudge will increase the win multiplier like it does in the Base Game, except now it can also increase if an xWays symbol lands above it, up to a maximum of 7x, meaning that a total of 14x is possible through xNudge Multiplying Wilds in the Free Spins

Free Spins may retrigger, but this game does not reselect a symbol like some do, so sadly you’ll be stuck with the same symbol you had from the start.

Our Verdict

Book of Spies Mission X Slot is an interesting concept that brings lots of different mechanics together to create a new experience.

NoLimit City’s xNudge and xWild features can make or break your game in both the Base Game and Free Spins, and the ‘Book of’ style of gameplay never seems to get old, and is a welcome mechanic within the Free Spins round.

Book of Spies Mission X Slot has some great potential, with maximum wins possible of 27,000x. This will be hard to get anywhere near though, with its high volatility rating it can quite often give you a stinker of a bonus, and the bonus itself is a little hard to trigger.

One big complaint is with the special symbol collected in the Bonus. Historically from the ‘Book of’ style of games, you’d only need 2 of one of the high paying symbols to trigger the stacked symbols.

Sadly, you’ll need at least 3 in Book of Spies Mission X Slot, regardless on whether your special symbol is high or low paying. Another feature that can either be good or really bad is the determination of spins based on where the Scatter symbols land.
