Question

I have one matrix for my grid (Memory game style):

Answer 1

Note that a memory game doesn't need to know that the cells are arranged in a rectangular matrix; it only cares if two cells have matching images. This example uses two instances of List<GameButton>

• buttons holds all of the memory cells.
• selected records the current selection(s).
