When you play Joker, you enter a 6-digit number in a race for the jackpot. The aim of Joker is to select as many correct last digits as possible from right to left. You win a prize with as few as two correct last digits.
A card jackpot game usually involves a pack of 52 cards plus a joker lying face down on a board. Qualifying participants are provided the opportunity to turn over one of the cards for the chance to win the prize. If the joker card is not drawn, the prize jackpots and the draw is repeated on another occasion.
