Unrivaled basketball hits the court for the first time on Friday and, according to ESPN, the debut league's style of play will look a little different from the 3×3 Olympic game's rules.

Unlike the half-court version currently played in major international 3x3 basketball competitions, Unrivaled's full-court edition uses slightly smaller court dimensions from a traditional 5×5 setup.

Similarly, the inaugural league's format follows a four-quarter setup, but opts for seven-minute periods rather than the WNBA's 10-minute quarters. The shot clock will also be a speedier 18 seconds versus the professional 5×5 game's 24 seconds.

Unrivaled victories, however, rest solely in fourth-quarter play. This "winning score" quarter denotes that the win goes to the first team to score 11 more points than the highest final third-quarter score. For example, if a game's third quarter ends with a 45-43 scoreline, the first team to post the target score of 56 points in the final period walks away with the victory.

This system essentially eliminates the possibility of overtime. League organizers also hope it deters the late-game fouls used strategically and prolifically in 5×5 contests.

Unrivaled 3×3 format revamps fouls

Speaking of fouls, Unrivaled is also condensing the free throw system to keep the game moving. Each player has six fouls to give, but each shooting foul will earn a single free throw at the line.

Those awarded free throws, however, will contain different point opportunities depending on the foul incurred. Fouled two-point shots grant a single free throw worth two points, while a free throw awarded from a three-point attempt will be worth three. All and-ones are worth one point.

With six players rostered on each of Unrivaled's six teams, the league also tweaked the traditional rule of fouling out to ensure games can be completed should they become especially chippy. If an athlete fouls out with only three available players left on their team, that player can continue competing. She will instead incur a technical foul — resulting in one opponent free throw — for each additional foul.

The new league's rules all point to Unrivaled's efforts to put an engaging, fast product on the court.

"This game is rooted in how you would play basketball as a kid on a black top," Unrivaled president of basketball operations Luke Cooper told ESPN's Kendra Andrews on Tuesday. "There's flow, there's pace. When you are watching, it feels like you are watching basketball... it's not a gimmick."

Unrivaled’s Series A investment round closed on Monday, with the new 3x3 pro basketball league raising $28 million from investors including South Carolina’s three-time NCAA champion head coach Dawn Staley and USC sophomore phenom JuJu Watkins.

Joining Staley and Watkins in cutting checks were several industry leaders, venture capital funds, and other prominent athletes like US swimming legend Michael Phelps and NBA star Giannis Antetokounmpo.

Also contributing to this round were several of the league’s original $7 million seed investors, including USWNT icon Alex Morgan and legendary UConn head coach Geno Auriemma.

NCAA standouts seek Unrivaled access

Unrivaled's inclusion of college stars is particularly unique, and likely sets them up to join the league after graduation.

Other than Watkins, who partners with the league as an investor, Unrivaled has a pair of NIL deals with NCAA players. The league inked UConn’s Paige Bueckers — the expected No. 1 pick at the 2025 WNBA Draft — last summer, and added LSU's Flau'jae Johnson to its NIL roster earlier this month.

Both Bueckers's and Johnson's deals grant them equity stake in the league.

Unrivaled hits the financial ground running

Co-founded by WNBA stars Breanna Stewart (NY Liberty) and Napheesa Collier (Minnesota Lynx) to offer a domestic alternative to overseas offseason play, Unrivaled has now raised an impressive $35 million ahead of its inaugural season, which tips off in Miami on January 17th.

"As women’s sports continue to surge in popularity and impact, we’re inspired by the growing momentum around Unrivaled and grateful for the strong support from our investors," stated Unrivaled president Alex Bazzell.

"Our players haven’t even taken the court yet and the foundation we are building with our partners unites unparalleled expertise, strategic insight, and an incredible product. Together, we’re setting the stage for Unrivaled for years to come."
