You choose your card from those displayed and at the end you are not shown the card you chose but that your card has been removed from those on display. I thought it was very puzzling until R and I played it simultaneously and his different card was missing too. It then clicked. All the cards displayed are different to what is first displayed, with the space where your card was presumably removed. Simple and clever.
R has lost a written document on the desktop and is rewriting it while uttering many bad words, then we are out for dinner.
I'll see if I can post something later today. If not, have a great weekend.
