You can test your running skills in Slope Unblocked, the best running game ever. Easy at the beginning, but tougher and more fun as you run!
You are in charge of a ball rolling down a steep hill in Slope Unblocked. As you move from side to side, your goal is to keep your ball straight on the falling slopes and avoid hitting any obstacles. Along the way, you'll gain speed and have a lot of fun as you try to beat your record. It goes faster as you go farther! It looks easy, but it's extra hard and fun to run! To make it more difficult, the track changes every time you play, adding new slopes, platforms, speed boosters, obstacles, and tunnels. You have to be very alert at all times if you want to win.
Have fun and good luck!
