I've been meaning to make a graphic to show on the screen but the main mechanic is the swap left, right, up, and down. So holding down left and swiping up, down, left, or right was tied to the left button. I think I can make the right button a quick discard. I kinda like that idea.
I'll play with that next. Something has gone wrong with the card following the pointer on discard anyway :)

Yeah it counts every hand you make during the 20 seconds, not just the ones that are on the board when it ends.
