Card Rules: Seven ================= .. index:: Seven Card 1. When a Seven is played, the next card must be of lower or equal face value; 2. When exactly three Sevens are played sequentially, the current player must disclaim ”Always Keep a Four”. At this point all players including the current player must show a Four from their hand. Those who do not will be considered to violate the rule to always keep a :ref:`Four` and receive an extra face down card due to the :ref:`Error`.
