Risk is a strategy board game adaptation focused on territorial conquest, where players deploy armies, form temporary alliances, and battle to control regions on a world map. Turns revolve around reinforcing territories, attacking neighbors, and fortifying borders against retaliation.

Digital adaptations typically add online multiplayer and various map variants to the classic formula, letting players face off against friends or AI opponents. Its appeal rests on the tension between cooperation and betrayal as control of the board shifts.
