This is fairly complex to edit. To change the questions/answers, simply fill in the text and cut/change the pictures.
To edit the main board. First take each action button (invisible) over each square and reduce it. Under the action button is the picture. I recommend copying each of the pics on the side. Then delete the existing and double click the box. Choose no fill on the colour menu. Then choose Fill effects at the bottom. Then picture, then insert.
Repeat for all changes to the main board then enlargen again all the invisible action buttons, so they overlay each square. Then save as….as a new game.
