Your run will also be canceled if you fly or teleport while doing the parkour. If you step on a checkpoint without getting one of the checkpoints before it, your run will be canceled. Parkour checkpoints must be performed in order and without skipping. The start pad will display your current best time for that lobby's course.
The start and end of each course is ( usually) marked with a light weighted pressure plate (gold), and the checkpoints are ( usually) marked with heavy weighted pressure plates (iron).
Every game lobby has its own parkour challenge as well as the Main Lobby and the Tournament Hall (19 total).
