Backyard Skateboarding is a game in the Backyard Sports series and the fifth game in the series released for the GameBoy Advance. A number of skaters gathers to raise funds to turn their backyard into a real skatepark. They participate in the Backyard Skate Tour where they help out people in the neighbourhood to earn stamps in their tour book.
The skaters start at Mom 'N' Pop's Skateshop and by earning enough stamps, they can move on to another shop. Every location also has a kid acting as a boss, offering a challenge. When defeated, the kid joins the group as a new playable character. As each kid also brings a sponsor, at the end of the game, there will be enough funds to build the ultimate park Skate Station Alpha.
The gameplay involves controlling skaters in a scrolling environment that can be explored freely in any direction. Skaters have different statistics based on air, balance, flip, speed and spin, which affects their performance. The main score is shown in the top left corner as "juice". Skaters can move, jump and perform tricks. Often parts of the environments can be used for grinds and jumps using ramps.
