Book of Golden Joker Review

Book of Golden Joker is a joker book slot from Retro Gaming, played on five reels of four rows. A golden joker takes the book's place as the star of the show.

Ten lines on a taller grid

Ten fixed lines pay from left to right, with line bets from 0.01 to 10. The top symbols pay up to 1,000× the line bet.

It blends a fruit-machine joker theme with book-style free spins.
