Ranked choice voting returns for this year's primary election for the first time in two years.
For a single race, voters will have the chance to choose up to five of their preferred candidates.
Like the name suggests, voters will rank them in order.
When the polls close, all first-choice votes are counted.
If a candidate surpasses 50% of the first-choice votes, they win.
"However, if no one hits that threshold and no one has the majority, then we start moving into rounds," says Omar Suarez, with the New York City Finance Board.
The rounds go on until two candidates are left.
The candidate with the most votes wins.
Voting begins on Saturday and ends on June 25.
