Variant 3: Players must, of course, keep their cards hidden. However, the rules do not state if they may also hide the number of cards they still have. Our idea was that, like in most card games, this number is known from everybody. However, it happens that, especially with players who know the game well, the game is much more tense if this number is hidden. This is easy to practice, since the square cards can easily be kept in one's hand, and since there are few ladies with fine small hands among hardcore gamers. Pity.
