It seems like this would be really difficult to play in-person. Assuming that the decision of whether or not to pass is made simultaneously, how to you manage that? You'd have to do something like write down your decision secretly on paper, and then have everyone reveal at the same time.
Or, more elegant, you just need a special card that each player has. Like a blank. When this card is played, everyone adds a blank to their hand. If they don't want to pass anything, they pass the blank. After that, everyone puts their blanks aside again.
