I know we’ve done ‘how does this work?’ threads in the past, so I’m sorry, but…

How does this work? Is it magic? I’m pretty amazed.

No matter what I do, it still gets it right.

just write down the first batch of cards, do the quiz to see answer and then you will get it.

Very funny, I like it!

Took a few seconds to work out how they do it!

Yeah, that is pretty amazing. I have no idea how it works, but then I have not idea how computers do what they do except work when I turn it on (most of the time anyway) 😀

Nahh … they got mine wrong.

They just added unknown cards to make them looks as if they were the original ones.

Simple trick.

AN old one but a good one

Nahh … they got mine wrong.

I’ll bet they didn’t..

Took me a good couple of confused tries to work it out… Simple when you twig!

Yep, 2 clicks through clever but simple

They show you half a dozen similar, but different, cards. Wow, your card has gone!! So have all the others.
