Kart On is a go-kart game where you compete in crazy races on 6 different tracks. Take part in a championship and compete to win the supreme title at the end of the season in "professional" mode, get the best possible time in "time trial" mode, or sign up for a bog-standard race in "Sunday cup" mode. Practice hard to get the gold medal and beat the best players’ scores!
