This slot is about a lot more than just diamonds! The red ruby is the scatter and gets you to the free spins round with only two—on the first and fifth reels. Gold bars on the center reels give you a random cash win. Yellow gems and regular white diamonds form a kaleidoscope of color on every spin! The animation in Black Diamond 25 Lines is awesome.
