For teams not in the lottery, the tiebreaker is simple: The NBA’s draw will decide the order they pick in the draft. They’re done.
However, for lottery teams, it’s more complicated. If multiple lottery teams tie for the same record, all their draft lottery combinations are merged together, then split evenly. If there is no perfect way to split the number, for example an odd number of total combinations to split between two teams, the draw is used to decide the order to distribute the remaining combination(s).
