This brand new slots game from NetEnt takes players on an underwater adventure through the eyes of an old fashioned submarine. Symbols include the captain, some of his crew members including the mad professor type and some lady explorers. Together with these symbols the high scoring card letters and numbers are represented from A for Ace through to nine. There are five reels and twenty paylines in this unusual slots game that really gives players an underwater feeling, with the hazy water logged symbols and the authentic sounds of water drops.
The gold idol is the wild symbol in this game where it can take the place of other symbols to make up a winning line. At any time during spins players can also benefit from a random scatter that offers between 2x -5x the coin bet placed for any one spin. The main scatter symbol is represented by the compass and this offers multiplying wins when two or more land on the screen and is also the key to the free spins. Five of the scatter symbols on the screen awards players 100 times the coin bet placed for that spin. Three or more of the scatter symbols activates the free spins. During the free spins there is a unique multiplier that increases with each spin. This multiplier starts at 2x and increases up to 6x, when it reaches the skull and crossbones on the multiplier chart, it is reset and can reactivate again with additional free spins. This is a unique feature and a welcome addition to this exciting slots game. Any win that is achieved is accompanied by a fanfare of music and when there is a big win of at least 1000 coins or more, a banner is displayed across the screen.
