Xtreme Dennis is yet another wonderful new addition over to the Dennis and Gnasher Games online category, this page that is only going to get better this week, as we have lots of great new games planned for it, and you should be here all the time and make sure that you are not missing out on even one of them. Of course, as you may have realized from the title of the game, this is a skateboarding game online, about which we teach you more right here, in order to make sure that you don't have any difficulties in playing it. Your goal is to help Dennis perform all sorts of stunts, flips, and tricks on his skateboard, something you're bound to enjoy a lot. You press the up arrow key in order to jump, avoiding all obstacles that come your way, and when you press the up arrow key twice, in order to perform tricks, and for each trick that you make you earn points, so try your hardest to get a score as big as possible. Good luck to all of you playing, and don't stop here since there are even more great games coming for you, none of them worth missing out on, trust us on that!
