Shifting Seas - Slot Review

Shifting Seas takes place at sea, but a very friendly version. It can be pretty spooky on the open sea, with strong winds and high waves. In Shifting Seas there is no sign of that.
The sea is smooth as a mirror, the sky is blue and in the distance a dreamlike island awaits us. This pirate ship seems to have entered a fairy tale world.
It’s a nice twist and unique design compared to Pirates 2 Mutiny, Rage of the Seas and Dead Man’s Trail.

Shifting Seas RTP, Stakes and Variance

The playing field of Shifting Seas consists of 6 reels with a varying number of symbols per reel. The symbols are divided in a 4-4-3-3-2-2 pattern. The reels can still grow, increasing the number of winning ways to a whopping 117,649.

There are four possible payout percentages in Shifting Seas, ranging from a minimum of 90.16% to a maximum of 96.15%. Don’t rob yourself of your wallet and play at the best casino online so that you assure yourself of a high payout percentage.

The bet starts at $0.10 per spin and can be increased to a maximum of $100 per spin. Shifting Seas also has a high variance and a nice maximum prize of 15,000 times your stake.


The main features in Shifting Seas are the shift win and avalanche. In addition, there are four types of wild symbols and a free spins round.

Shift win

Every time you land a winning combination, the shift win becomes active. This shifts all reels 1 position to the left, giving you a new reel on the left and removing a reel on the right.

In addition, all reels become 1 symbol higher, up to a maximum height of 7 symbols.

When you get a new win, all reels move up another position and you get one more symbol with each reel. If you don’t get any new wins, the playing field is reset to the basic setup and you move on to your next paid spin.

PROs & CONs of Shifting Seas


  • Fairy tale design of pirate theme
  • Shifting reels, Avalanche feature and special wild symbols
  • Free spins round with Wild Reels


  • RTP could drop below average in some casinos


The Avalanche feature comes into action at the same time as the Shift Win feature, when you land a winning combination. All winning symbols are hereby removed from the playing field, making room for new symbols. This also continues until no new wins are created.

Wild symbols

The regular wild symbols of Shifting Seas are just as valuable as the highest regular symbol. So for 6 wild symbols you get a prize of 5x your bet. In addition, the wild symbols are also a great help in creating winning combinations. These symbols can replace any regular symbol.

There are also 3 special types of wild symbols. These become active when their symbol is used in a win, or pushed off the playing field.

  • Boost shift symbol gives an extra reel shift, creating a new reel on the left side and disappearing the right reel.
  • Symbol rush symbol randomly changes 4 to 8 symbols on the playfield to the same symbol.
  • Wild surge symbol randomly changes 1 to 3 symbols on the playfield into wild symbols.

Shifting Seas free spins

To reach the free spins round of Shifting Seas, you must not only land a bonus symbol on the playing field. You must also clear the symbol from the playing field using the Shift Win feature. If you manage to do so, you get 8 free spins to start the round with.

During the free spins round, you will receive an additional 4 free spins if you clear another bonus symbol. During the free spins round, a wild reel can land on the playing field. This means that an entire reel is covered by one big wild symbol. The reel is also given a multiplier that starts at x1. Each time the Shift Win feature activates, the Wild Reel moves 1 spot to the right. When it slides off the right side of the playfield, it returns to the far left.

The multiplier is increased by +1 in the process and you get an extra free spin.
