The Gold Cup is up for grabs.
The World Wheelchair Basketball Championship is held two years after every Paralympic Games, and this year's event is being hosted in the Korean port city of Incheon.
"Played on the same court as any other basketball game, wheelchair basketball is considered one of the most exciting and dynamic sports for those who are physically challenged -- a reason why the paralympics always ends with a wheelchair basketball play-off."
The rules are slightly different on wheels.
You can dribble as many times as you like, but you'll be called for traveling if your wheels touch the floor more than twice after receiving or dribbling the ball.
Some 320 athletes and officials from 16 countries have come to Incheon to take part -- making this the largest event in its history.
All the teams are aiming for the final on July 14th.
"We are very pleased because we start the tournament with a win. So we just have to concentrate on each game, game by game, in order to hopefully make the final at the end of the tournament. But with 16 very good teams, it's going to be very very difficult."
"Fact is, for team sports, it's difficult to get country's support. There's one gold medal at the Paralympic Games, there's one gold medal here, unlike other sports where one athlete can get five medals.
The only way we can keep them interested was to increase the number of opportunities for them to get to the world championship."
The year's Gold Cup also serves as a test-event for the Incheon Asian Para Games set for October.
