This is an expansion for the base game Azul. It requires the original game to be played. Azul: Crystal Mosaic contains double-sided player boards, with each board offering new challenges and exciting new strategic opportunities. The "Crystal Mosaic" of the title is actually a plastic overlay that provides a recess to keep tiles from being accidentally bumped out of place. Four overlays are included in this expansion. 2–4 PlayersPlaying Time: 30–45 MinAge: 10+ Designer: Michael KieslingArtist: Chris QuilliamsPublisher: Next Move Games
