Spearhead Studios has introduced its third flagship game of the year, Book of Spies: Mission X, specially designed using Nolimit City’s innovative mechanics xWays and xNudge.

Spearhead's brave and beautiful heroine, Lara Jones, leads a team of fearless special agents on a mission to break into the ultra-secret digital vault of an evil spymaster to steal his Book of Spies.

As regular players of "Book of" games expect, during the free spins a special symbol is chosen which can expand on the reels to be evaluated as a line scatter.

The game was designed using Nolimit City’s trademarked xWays and xNudge mechanics following a landmark deal signed at the end of August 2020.

xWays is a random reel modifier that allows any given spin to produce a different number of mystery symbols across the reels. xNudge is a wild symbol where the win multiplier increases by win for every step the wild nudges.
