One feature in the card game that gives players an extra challenge & reward is Rummy Gold's 51 Bonus. The 5 of Hearts and 1 of Spades, which are the 51st and 52nd cardsjoyrummy in a standard deck, must be used to create a pure sequence in order for players to access this bonus. The name of the bonus comes from this requirement. The 51 Bonus introduces a new level of strategy to the game, requiring players to strike a balance between completing their standard gaming goals and completing this unique sequence.
