Nontransitive dice set of dice (A, B, C) has a 'highest' die, the second set of dice has a 'lowest' die. Rolling the three dice of a set and using always the highest score for evaluation will show a different winning pattern for the two sets of dice. With the first set of dice, die B will win with the highest probability () and dice A and C will each win with a probability of . With the second set of dice, die C′ will win with the lowest probability () and dice A′ and B′ will each win with a probability
