How do Bonuses work?
Bonus cards
On some levels, bonus cards are hidden in the Tableau. When you open a bonus card, Ρards are added to the Stock, their number corresponding to the one indicated on the flip-side of the bonus card.
Joker
A Joker is a wild card that can be any card you desire. So, you can use it to remove any open card and even some obstacles from the board.
Five extra cards
If you run out of cards in the Deck, you can always get 5 additional cards for coins to complete the level.
