As a game, this one provides you with a layout of five reels and three rows, so regular slots gamers will be able to easily adjust to playing this game. Upon this interface are the game’s various different icons, and these start with the frequently seen A, J, K, Q and 10 symbols. These have quite a metallic look to them so as to tie in with the game’s overall theme. Joining these standard icons are five different characters from the underwater vessel. These start with the engineer, who has purple braided hair, goggles and a large wrench in her hand. Then there’s the deep sea diver, who looks all ready to go out on a mission across the sea floor. There’s also a blonde-haired woman who looks like somewhat of a scientist, carrying her books around. The captain of the ship is next in line, taking a glimpse through the submarine’s periscope, and finally, a man with red hair and glasses who is clutching on to some treasure maps is the final icon.

Alongside these basic features, NetEnt have added a total of 20 separate pay lines to the game. However, if you prefer to wager on fewer bet lines, you can do so by using the slider bar underneath the ‘Lines’ box, or simply by clicking on one of the numbers down either side of the reels. Further customisation can be done on the amount of the wager that you place per round, and this starts with the coin value. Here, you can choose from values between €0.01 and €0.50 per line, and following on from this, you can adjust the bet level between one and 10. Altogether, this allows you to place a maximum overall wager of €100 per spin, which is a total that can be reached with the ‘Max Bet’ button.
