Becoming Olympic in 2020
3x3 (pronounced 3 on 3, 3 by 3 or 3x3) basketball is a form of the game played three a side on one hoop. It is the largest urban team sport of the world (ESSEC study commissioned by IOC). This basketball discipline is currently being promoted and structured by FIBA, the sport's governing body. Its main competition is an annual FIBA 3X3 World Tour, comprising a series of Masters and one Final tournament awarding six-figure prize money in US dollars. The FIBA 3x3 World Championships is the highest tournament for national 3x3 teams.
3×3 has been a basketball format long played in streets and gyms across the world, albeit in a less formal way. Starting in the late 1980s, three-on-three began to become standardized throughout the United States, most notably through the Gus Macker and Hoop It Up tournament series, which held large events across the country that invited teams and players from all skill levels. Adidas launched its now-discontinued streetball competition in 1992. Since then, the number of 3×3 events and competitions has been steadily growing all around the world.
FIBA took the decision to first test 3x3 at the 2007 Asian Indoor Games in Macau. Further test events were held in April 2008 in the Dominican Republic and October 2008 in Indonesia. The international debut was at the 2009 Asian Youth Games: 19 teams in the boys' tournament and 16 teams in the girls' tournament. All games were held at Anglican High School, Singapore. Finally, 3x3 made its worldwide competitive debut at the 2010 Summer Youth Olympics in Singapore. The competition featured 20 teams in both boys' and girls' categories. The competition was held at the Youth Space, Singapore. Since then World Championships in both open and U18 categories are held on a regular basis.
After the success in Singapore, FIBA launched a full programme to make 3x3 a stand-alone discipline with its own regular competitions. 3x3 is scheduled to make its Olympic debut at the 2020 Olympic Games.
FIBA releases from time-to-time a 3x3 supplement to its official basketball rules. The rules state that regular FIBA rules apply to all situations not specifically addressed in the FIBA 3x3 rules. The current set, both in an abbreviated version and longer format, was published in January 2015 and a video has been posted on YouTube.
Under the 2015 rules, the departures from regular full-court basketball are as follows:
FIBA sees 3x3 as a major vehicle for promotion of the game of basketball throughout the world. FIBA Secretary General and IOC member, Patrick Baumann considers: "The 3x3 concept has all the elements and skills required for basketball, it has inspired and will continue to inspire many great players in the future. At the same time, it is the easiest and one of the most effective ways to bring youngsters to basketball, keep them and promote our game. Finally FIBA 3x3 can and will promote key educational and social values to the next generations".
FIBA is pursuing a unique click and brick strategy to implement 3x3. FIBA has developed a digital community, 3x3planet.com that acts as repository all FIBA-endorsed 3x3 events worldwide and offers all players an individual world ranking based on the points earned by players at FIBA-endorsed 3x3 events.
Any event in the world can become FIBA-endorsed by using FIBA's freeware, EventMaker, to organise the event. All FIBA-endorsed 3x3 events are classified within an established competition hierarchy, thus forming an official competition network. The pinnacle of this competition network is the FIBA 3x3 World Tour, that is a series of World Tour Masters and one Final. A team can qualify to a World Tour Masters by playing in any of the designated World Tour qualifiers.
The NBA has also embraced 3x3, holding a summer series of tournaments known as "Dew NBA 3X" since 2016, where local amateur players from around the US compete in regional events for cash prizes and a finals berth. The men's and women's NBA 3X champions then advance to the USA Basketball national 3x3 championship to potentially represent their country internationally. These tournaments also include live music performances, 3-point shooting contests for fans, an NBA 2K eSports competition, and appearances from current NBA players. In 2017, entertainer Ice Cube and entertainment executive Jeff Kwatinetz founded BIG3, where former NBA and US college basketball stars compete in a traveling league using rules slightly different than the FIBA rulebook.
After the success of the 2010 Summer Youth Olympics, FIBA established a regular World Championships, always men and women simultaneously, in both open and U18 categories. The open category is played every two years (in even numbered years, since 2012), whilst the U18 category is played every year (since 2011), except in Youth Olympic Games years.
Classification to the World Championships is based on the 3x3 Federation Ranking, which ranks all National Federations based on the 3x3 Individual World Ranking points of their top 100 nationals (with a confirmed 3x3planet.com account) in the respective category (men, women, U18 men, U18 women).
In addition to team competitions, World Championships also feature individual competitions such as dunking and shooting.
On June 9, 2017, the Executive Board of the International Olympic Committee announced that 3x3 basketball would be added to the Olympic programme for the 2020 Summer Olympics in Tokyo, Japan, for both men and women.
