The title challenger is the winner of a ladder with 5 stages:

L1: Winner B1 vs winner B2
L2: Winner L1 vs winner C
L3: Winner L2 vs winner A
L4: Winner L3 vs runner-up S
L5: Winner L4 vs winner S

The last stage of the ladder is a best-of-three playoff where the winner of the S League gets a 1-game advantage. Thus, in order to win this stage, a single win suffices for the winner of the S League, while the winner of stage L4 needs two wins.
