that is it.. now u have a ascending number for each card in the screen already existing at the start of layout)... that being said as now thinking the cards are the same sprite but duplicated.

(if you dont know what inverted is ... you right click the condition and there is a invert action that basically acts like else.... but more secure then else... cause else means anything but that action .. that can mean a glitch a bug etc that you might not want to trigger it ... while reverse means only uid not matching that variable in this case.)
then you need a hover out of cards reset for the picking so the last card picked card won't stick to changed.
and that is basically
and that is it... easy 5 conditions.
