Blue Dolphin Review
Blue Dolphin is an underwater slot from Amatic's 2015 catalogue. It plays on only five lines, and its free spins are the classic kind: 15 spins with every prize tripled.
Five lines under the sea
The game uses a 5×3 grid with five fixed lines. Sea creatures make up the symbols, from squid at the low end up to the blue dolphin, the top prize.
Crown scatters pay from anywhere on the screen as well as starting the bonus.
