Shifting Seas Features

Shifting Seas is not your average pirate slot. There is a new mechanic called Shift Win that causes the rightmost reel to disappear when a win lands on the reels. This leads to a new reel appearing on the left side as well.

When a special wild is pushed out of the game, the special wild is activated. Additionally, the boost shift feature results in an extra reel shift that enables a new reel to be added to the left side of the game area. All the symbols in the left location will be copied into this new reel.

There are special symbols that have been previously mentioned that can land which include:

The bonus game is triggered by having a Shift Win pushing out the bonus symbol. 8 free spins are handed out and extra spins can be gained by pushing out more bonus symbols. During the bonus game, the wild reel may appear on any reel.

It appears on the first reel and will move one position to the right after a Shift Win. This carries a multiplier starting at 1 with each Shift Win making the Wild Reel reappear at the left side and increase the multiplier and award an extra spin.

Shift Win

Each win causes the rightmost reel to disappear and a new reel appears on the left-hand side. In addition to the Shift Win, there are avalanches that drop in new symbols from above causing even more excitement.

If a Shift Win pushes out the bonus symbol, then 8 free spins will be triggered. The bonus game starts when the Shift Win has ended and additional spins can be gained by pushing out a bonus symbol during the round.

Shifting Seas Review

The pirate slot theme is definitely hit and miss amongst players. Some of these games take themselves too seriously or fail to feature anything memorable in the slot.

Thankfully, that is never the case with Thunderkick in Shifting Seas. Playing on 6-reels with up to 117,649 ways to win, this slot contains a unique shifting mechanic as well as free spins and wilds uncovering amazing booty of up to 15,000x the stake.


Like most Thunderkick slots, the design of Shifting Seas is distinct and notoriously Thunderkick. The designs of the characters are both cute and grotesque in creating something wonderful.

In the distance, there is an island surrounded by water and the reels are set in the middle of the ocean. There's not a huge amount going on in the design but it certainly looks stunning.

Alongside the ambient noises of water and the ship, there is a jaunty pirate theme that creates a lighthearted tone for the slot that is both fun and hilarious at the same time.


Shifting Seas is unlike any other slot you've come across as the Shift Win mechanic is certainly entertaining. Everything revolves around this mechanic and leads to the bonus round and other features. Ultimately, each win shifts the reels and kicks off symbols to the right and adds in new ones on the left.

The bottom of the screen contains the spin button as well as the bet level button. Players will be able to find the paytable and other settings just to the right of the reels.

Win Potential

Ultimately, the win potential for Shifting Seas is fantastic with a strong RTP of 96.15% as well as a high volatility level leading to larger wins but less frequently.

The maximum win for this slot is 15,000x the stake which is a large amount that will definitely keep players happy. The biggest wins can be achieved through the bonus game with the multipliers.

Our Verdict

It's clear that Thunderkick is trying to do something original with Shifting Seas and thankfully it works. The Shift Win mechanic is incredible and we're hopeful that slot players will enjoy it as much as we did.

Of course, the design fits in the wonderful style of Thunderkick and the win potential is certainly something that will delight players. For an original pirate slot that definitely defies expectations, give Shifting Seas a spin.
