After several game days, the girls will begin to like you. In the beginning, you don't have much to do but to watch the girls doing whatever they like doing. The game plays very similarly to Sexy Beach 2, but adds more locations, improved interface and interaction, quicker date pacing, etc. You will have to date those girls and eventually have sex with them. These girls are characters from other Illusion games: Esk from Des Blood 4, Eo from A-GA, etc.
As you check in the local hotel, you find out that there are six lovely girls inhabiting the island.
The premise of Sexy Beach 3 is simple: there is a beautiful island called Sexy Island you, the nameless hero of the game, have just won a trip to the island in a lottery.
