One bad app

First game, i scrolled past my number but took note of what symbol it was. The app got my choice wrong. Ok.
Second game, after taking note of all the cards, i realized it changed them all and removed one card. Not very nice try.
Third game, it just mathimatically removes every number it is imposible to land on each time. You will always end on 12. It works... Mathimatically, not through magic.
