Emperor of the Sea is not a popular slot with many players. That doesn’t mean it’s a bad game; give it a go or search popular online gambling slot games. Overall, Emperor of the Sea is one of Microgaming’s older slots, and the graphics and animations are beginning to show their age. Our Team do not believe it’s a big deal because the graphics are wacky and add to the game’s charm. RTP 91.6% return rate and mobile phone friendliness make it worth checking out.
