CHOOSE ONE MARBLE AND DON'T SWITCH

RULES:
There are 3 legs; and each of them has a time limit.
Leg 1 Time: 300 TTL (time to live) seconds
Leg 2 Time: 450 TTL seconds
Leg 3 Time: 750 TTL seconds

Marbles must complete all three courses in 750 TTL seconds, otherwise, they have only one chance to break through the legs.
Also, the marbles must not go super hyper, because that might also count as a death if they shoot out of the course.
NOTE: A relatively low percentage would pass through all three legs so good luck!

PRESS 0 TO START (The TTL seconds start right when you start the stimulation)
