More than 1,000 athletes representing 40 tribes are competing in Brazil's Indigenous Peoples' Games VII this week.

The event features traditional games of various tribes. There's Xikunahity, a type of soccer where players can only use their heads. And tihimore, a form of bowling using corn as pins and quince as a ball.

The games started in 1996 with just 400 athletes and 29 tribes. It is held in a different city every year, growing bigger each time.
