In Star Wars Villainous: Power of the Dark Side, each player takes control of one of five Star Wars characters: Darth Vader, Asajj Ventress, Kylo Ren, Moff Gideon, or General Grievous. Each player has their own villain deck, fate deck, player board, and 3D character.

​

On a turn, the active player moves their character to a different location on their player board, takes one or more of the actions visible on that space (often by playing cards from their hand), then refills their hand to four cards. Cards are allies, items, effects, and other things. You need to use your cards to fulfill your unique win condition.
