The player must choose to play as David Bennett, Jessica Knight, or create a customized Sim, who boards a cruise ship for singles named Solomon Queen, only to have it crash and leave them drifting on the ocean clinging to a crate. In 'Shipwrecked and Single' mode, the player is subjected to a scenario-driven style of gameplay. The Sims Castaway Stories features the choice of either playing in a story-driven mode titled 'Shipwrecked and Single' or a more sandbox 'Wanmami Island'.
