I'm trying to make a memory card match game for my child where matching 2 cards are not identical.
To be specific, the cards are 52 in total with big and small alphabet letters.
A matches small a, B matches small b and so on.
the cards are in each frame in one animation(A-Z, a-z) and all I need to do is draw out random frame number.
But I have no idea how to draw out random sets of (big letter, small letter).
Can anyone please help?
