Time to check your speed and reaction! On each new level of Stack Rider, the task of overcoming obstacles will become more difficult. To reach the finish line, you need to collect all the balls located in the path of your hero. Only if you have a sufficient number of balls under your feet can you jump over the high walls that appear along the road. As soon as your hero is out of the ball, the passage will be disrupted. There is nothing wrong with that, but you will have to go through the level again!
