Welcome to the Marble Algicosathlon! The marbles gain points each round, and every round the marble with the least points gets eliminated.

Update 1: Olive was only in the 1st round no matter who was eliminated...
Update 2: Legs 8 and 13 didn't quite work because the timer that controlled them wasn't being set before leg 8.
Update 3: Leg 14 didn't work at all because the death timer resetter for the pennies there was being killed at the start of leg 4...
Update 4: So apparently there were two death timer resetters, one of which died at the start of leg 4 but didn't work properly so the pennies at leg 14 died by leg 4 anyway...
