In a way it's similar to gantz, since people are basically forced to be a part of a 'game', the purpose of which they aren't told.
Different premises but both revolve around a deadly game that tests the limits of the characters' ability. Both series' games include a set of rules that needs to be followed to avoid consequences. Throughout both series, alliances are forged and revelations are discovered. While Liar Game tests more on the intellectual ability of the players, Gantz revolves more around the survival horror trope. Recommended for fans of survival games.
