I am trying to make shapes disappear when I click them (Not in a predetermined order) is this possible

I don't know what this game is, but you are describing an interactive menu as used in DVD meus, a web page or electronic game; click on any button and that button is removed while the other buttons remain

if you have 3 objects, you need 4 slides as follows:

slide 1: A B C

slide 2: B C

slide 3: A C

slide 4: A B

make a link from each of the buttons A B C in slide 1 to link to the appropriate slide: 2, 3 or 4

click on the button to select it, this can be a drawn object, photo or text

inspector > hyperlink tab > link to slide > slide > select the number of slide

if you then want to make further buttons disappear, in a second order choice, you will need to make 7 slider

you are on slide 2 and you want B to disappear
