The dragon’s egg can be found in the lower right-hand side of the level screen. The egg contains surprise gifts that can be won after racking up a chain bonus (clearing five cards). Every time you make a move other than clearing a card, the bonus goes down by 1. If you use the Undo button, your bonus is erased. Gifts that can be won are +1 card, +2 cards, +3 cards, and Extra Joker.
