High Hills is a fun racing game that you can also play on your mobile. Drive up and down, collect coins and fuel. You can upgrade your vehicle and get the most out of your coins. You will encounter many obstacles on the way, but you will certainly enjoy it. Avoid sharp objects or roll in a ball, these and many more you will find during your journey. Do not forget to make flips for extra coins. Just do not overdo it because you could just end up on the roof and you reall do not want to. Have fun.
