cool pairs displays a scrollable 40 cards deck, the standard for many Italian games, in 3 columns.
The deck comprises of 4 suits with cards 1 to 7, jack queen and king each. The order of the cards is randomised each game.

You may tap any card on the deck. If the card immediately to the left of it, or the one next to it (ie you may jump one), is of the same suit (hearts, diamonds, spades and clubs) or the same value (1, 2, 3, 4, 5, 6, 7, jack, queen, king) when you tap it the second card you tapped will disappear from the deck and will be placed at the bottom of the screen in a scrollable carousel.

The game is won when you have eliminated the whole deck but 1.

Do not expect to win very often and, if you like easily winnable games, I am afraid this is not for you.
On the other hand, if you like a challenge cool pairs will not delude you.

Have fun!

Tips:
1) tapping any card on the carousel at the bottom of the screen will return that card to the deck, a sort of interactive undo.
2) if you tap a card that is a valid match ie same suit or value to the first card tapped and nothing happens, tapping the first card twice and then the match to the left will work correctly.
