the clock track is an expert track on BTD5 that can be unlocked on level 33.
the bloons will enter at the top, at the number 12 and will follow the hour hand and then come into the edge of the clock. They will travel around the outside until meeting the minute hand then come icloser inwards making there journey shorter thus faster.
The minute hand like the switch track will change every round making the bloons stronger and having less to go.
