In this mode, the character controlled by the player will continuously run on an ever-extending road. Various obstacles will appear on the road, such as trees, boulders, traps, etc. At the same time, there are also collectible items such as gold coins and energy-boosting items. The player's goal is to run as far as possible while avoiding obstacles and collecting items. The difficulty of the game usually gradually increases with the increase in running distance. For example, the frequency of obstacle appearance will become higher, or more complex obstacle combinations will appear.
