Set in the "My Little Pony: Friendship is Magic" universe, town librarian Twilight Sparkle secretly writes relationship (shortened to "ship") fan fiction about herself and everyone else. Nobody is safe from her overactive muse. TSSSF uses three decks of cards: Ponies, Ships and Goals. Players use Ship cards to pair different Ponies together on an expanding grid, earning VP for completing Goal cards for different combinations formed on the grid.
