While the FINA Artistic Swimming World Series circuit has been around since 2017, the Super Final leg originated in 2019. At the Super Final, the first twelve highest-ranked National Federations in each event (Solo, Duet, Mixed Duet and Teams) are invited to attend and continue to collect points to determine the winner in each category.
For the 2021 Super Final in Barcelona, all National federations were invited to participate and continue earning points towards the final ranking and price monies. The only requirement is the participation in at least two ASWS legs, including the Super Final.
