Maybe the secretions on the contaminated coffee mug handles and plastic tiles took longer to dry than those on the playing cards & poker chips.
Wild guess: air temperature and humidity should make a big difference in how quickly things dry. As hands are constantly sweating, I could imagine that there is a kind of threshold humidity/temperature beyond which hands have enough moisture to sustain viruses?
