Similar to Accordion, the object of Royal Marriage is to compress the entire deck to join the King and Queen of Hearts together.
All cards are dealt out into a continuous sequence.
Compress cards that share the same rank or suit, but only if they neighbor each other, or are separated by one card. For example, if you have: 5 of Spades, 8 of Clubs, 5 of Clubs; You could compress the 5 of Clubs onto the 8 of Clubs (getting rid of one card) OR you could compress the 5 of Clubs onto the 5 of Spades (getting rid of 2 cards). Cards are moved to fill in gaps.
*To compress cards, first tap one and then the other.
The game is won when all of the cards have been compressed and only the Queen and King of Hearts remain on the screen.
