My question is not how to merge pygame and kivy screens. My problem is that I am working using kivy but in my code I added a function which runs a pygame program. When this program runs, the screen size remains the same as I defined it in the pyga code but all the items in the pygame screen shrink a bit in size and move a little bit top-left
Another problem is that when the both screens( kivy and pygame) run, they don’t respond to click on the close button.

I’m trying to build a Rummy game using Python. let’s suppose that the hand of a player is made of the following cards: [(‘3’, ‘Spades’), (‘5’, ‘Spades’), (‘6’, ‘Spades’), (‘7’, ‘Spades’), (‘7’, ‘Spades’),(‘5’, ‘Hearts’), (‘Q’, ‘Hearts’), (‘3’, ‘Clubs’), (‘5’, ‘Clubs’), (‘8’, ‘Clubs’), (‘Q’, ‘Clubs’),(‘6’, ‘Diamonds’), (‘Q’, ‘Diamonds’)]. I need a stratigy to follow in order to create a function that will allow to form valid melds from those 13 cards.
