This game is easy: a card is drawn, after which you have
to predict if the next card will be higher or lower than the
current one. The goal is to make as many good predictions
as possible, preferably in a streak.
As each card occurs only once, you can influence your luck
by keeping track of the cards that have already been played.
Oh and.. 2 is low, ace is high,
all suits are of equal value.
