the major of program is there,it's doesnot flip well.
anyone can help?

my flip function related to the if(found) then it's will flip,according to my flip function it's just flip top and button and another 6 corner do not flip,it's a my reversi game btw

Let's slow it on down.

What do you want to do?
What do correct results looks like?
How will you test for correct results?
What will incorrect results look like?
How will you test for incorrect results?
