No Trump 500\n\n Players must always follow suit and may use the joker to trump a trick only if they cannot otherwise follow suit. A player may lead a trick with the joker by naming the suit to be followed, but may not name a suit to which the player has previously claimed to be void.
Many cards have special actions: 2-6 - played to move a marble that number of places. Joker - move one of your marbles (from home or the track) to an opponent's spot on the track, sending their marble home. Marbles in the finish area are safe from this attack.
