How to Play Nauticus slot online

Nauticus is a five reeled video slot with twenty pay lines and three rows of symbols at the screen. Playing this slot machine is possible by stake in range from one cent to ten euro per each of the lines. This way, the maximal acceptable bet per spin can reach two hundred euro per spin.

This model is also provided with the special symbols with advanced options, free spins, bonus rounds and lots of other interesting gaming options, which make the gameplay more exciting and beneficial.

To form a winning combination, you would have to pick several similar elements. The symbols have to make a continuous chain at the active line, starting from the first left reel. As usually, only the highest combination in each of the chains is charged with payoff. Smaller combinations fully included into more valuable, are not considered to be winning.

An amount of the payoff is calculated by the standard formula: the bet per line is multiplied by the index, provided by the table for each of the possible combinations. The maximal index for the standard symbols is x250. Please read about exceptions below.

The gambling feature is not provided by the rules of Nauticus slot machine, that’s why the total payoff for a round is immediately transferred to the player’s account.

The theoretical cash back index of Nauticus video slot is 92,6% according to the information provided in the table with rules and indexes.

Nauticus Symbols, Wild, Scatter

The gaming symbols, which you can see at the screen of Nauticus slot machine, are all possible thematic pictures, including images of a diver, an octopus, a table of some tool, an anchor, as well as signs of the values of playing cards from jack to ace made of tubes and gear-wheels.

There are also several special symbols in Nauticus slot machine, such as Wild (a shark), Sticky Wild («Nauticus» submarine), Scatter (an underwater mine), Free Spins and Bonus (you can recognize these symbols by corresponding captures). We would like to discuss their special functions below:

  • Wild doesn't appear at the first reel, that’s why it is not able to form the combinations on its own. However, it can replace other standard symbols when it is necessary to help making a combination.
  • Sticky Wild drops out only during free spins (please read about it below). It doesn't appear at the first left reel either, but replaces other elements and holds its place during several spins (up to five).
  • Scatter symbols trigger the bonus round named Pick a Mine when three and more such symbols appear at any position of the screen. In such case the player also receives a payoff in amount of one total bet.
  • Free Spins trigger up to sixty free spins when three, four or five Free Spins symbols drop out anywhere at the reels. The player is also provided with a winning in amount of one total bet. The game goes on on the same conditions during free spins.
  • Bonus - three and more bonus symbols anywhere at the screen give a right for participation in the prize round named Torpedo.

  • In Torpedo round you would have to burst underwater mines with torpedo. More successful you shoot, higher your final bonus payoff.
  • In Pick a Mine round you would have to select mines and receive winnings for them. Its amount partly depends on the total bet per round.

Details of both these games can be found in the informational section.

Should You Play Nauticus Slot for Real Money?

Although Nauticus slot machine doesn't have spectacular graphics or a stunning animation, it makes a good impression due to the great variety of the special symbols and the bonus options, which are triggered by them. It is enough to remind two thematic prize games and free spins. We think that the main disadvantage of this video slot is its low level of the theoretical cash back index.
