People seem to assume every machine has a chance at dropping plat egg. After a couple of runs I realized this is not the case and that egg machines still have colours.

Check chat everytime you loot a plat egg (while running with plat tiers). Everyone loots plat eggs from the same machines. If it was truly random it would be 1 person looting. When you realize this a lot of things start to make sense.

Basically... just pray your map spawns a plat machine.
