It seems like what the rules actually mean is that you're not allowed to communicate except via the one form of communication that they've designated as "not communication". The spoiler section also says you're not supposed to just count upward in seconds, which is strange because that's clearly both allowed and optimal. Maybe they mean that that's not the most fun way to play. But why would I want to play a game where fun was inversely correlated with the probability of winning? I wonder what the optimal strategy is for the version where you're really not allowed to communicate (i.e. if no one plays a card immediately then you've communicated and therefore lost). Presumably you have to calculate based on the number of players and cards remaining how likely it is that you have the lowest card. You could also skip the later rounds by immediately playing a high card, at the cost of one life. I bet with enough practice you could win some games. EDIT: On second thoughts, you're still communicating when you either play a card or not. So maybe that variant isn't so fun. It basically becomes everyone playing their lowest card as quickly as possible, and hoping that the lowest one lands first.
