What the mechanic does
What the Book of mechanic means?
The Book acts as both scatter and wild, and at the start of the bonus one expanding special symbol is randomly chosen.
Why these games?
A mechanic is listed only if it is marked in the game's own feature list. We do not infer mechanics from videos or ads.
Does this mechanic raise the RTP?
Not automatically. RTP is a game-specific figure and is stated separately on each game's page. The mechanics tell how wins are formed — not how often they occur.
