Explore mode is the main attraction of Run 3. There are currently 298 playable levels, and at least 306 will eventually be playable. Explore mode consists of the Main Tunnel, which has 65 levels, more than 20 side tunnels, two minigames, and cutscenes that fit between some levels. You can unlock some characters from playing Explore mode, and the winter and Halloween costumes. For more information about the individual tunnels, go here.
