The Wild Shark:

Since the slot machine takes place in the depth of the oceans, it makes sense that one of the unique symbols is the shark. The shark is the wild symbol that will land during the main gameplay. It can only land on reels 2, 3, 4 and 5. The symbol will substitute for all icons, except the scatter and the bonus. It will replace the icon that is going to result in the maximum award possible.

The Sticky Wild Submarine:

The submarine is the second wild of the slot machine that can only appear for you during the free spins round. It can only appear for you on reels 2, 3, 4 and 5. It will not replace any of the other scatter bonus symbols, but it will substitute for the symbols that would result in the highest possible award. The wild is also sticky, which means that it will remain in its position for the duration of the free spins.

The Bonus Scatter:

The slot machine has a bonus round that you can trigger whenever you manage to get three of the torpedo scatter icons anywhere on the reels. You are going to activate the Torpedo Bonus which is a 2nd screen bonus that can result in massive awards.

The Free Spins:

If you think two wilds and a bonus round is enough, you better rethink it. Nauticus comes with a free spins scatter icon. You will need to get three of those to trigger the free spins round. You can claim up to 100x free spins.

The Mine Scatter:

The mine Scatter icon will trigger the pick a Mine bonus. You will pick one of the mines, and you will claim massive awards.
