This fantastic and feature-packed video slot will take you to the undersea travels in Nemo’s submarine. The slot boasts of having four different wild symbols, wild multipliers, an alluring free spin bonus and some other features that make your gaming more intense with each new spin. The slot would be appealing to high rollers since the max bet is $200 per spin, but if you are playing on a budget, 40 cents will suffice to spin the reels with all lines enabled. The top three prizes in the slot are $1500, $1000 and $750.

Bonus features

There is a depth indicator to the right of the reels, and with every new spin, the submarine located on the depth indicator moves down a little, showing that Nautilus is submerging. There are four checkpoints on the indicator that activate a new feature as soon as Nautilus passes each checkpoint, and the deeper you submerge, the more rewarding the features. You start playing with a regular wild symbol that acts as a basic substitute. All the features triggered when Nautilus is descending are related to wild symbols:

• Checkpoint #1: a regular wild is replaced with x2 and x3 multiplier wilds
• Checkpoint #2: all wilds become ‘pressurized’. When a pressurized wild symbol lands in any position, it transforms all symbols below it into wilds
• Checkpoint #3: all wilds become clumped, which means they morph a random number of adjacent symbols into wilds
• Checkpoint #4 (final). One to three reels will become wild.

Nautilus begins to ascend and pass the mentioned sections in the back order when the arrow on the Pressure Meter reaches the maximum value. When the submarine begins to ascend, the wild features downgrade from wild reels down to regular wilds until Nautilus reaches the top of the depth indicator. The ‘descend-ascent’ cycle then repeats.

The slot also features a free spin round unlocked by 3 Bonus symbols. You are awarded 8 free spins, during which all wilds that landed on the reels will stay in place for the duration of free spins.
