How to set up a rolling lottery for ppt

You take a slide, put some pictures on it, mark the serial number of the lottery, then create several blank slide pages, and write the awards corresponding to the lottery pictures on them (for example, write: AwardNo. 1 on one page: what, what, what), then return to the lottery page (the first page has pictures and lottery numbers), right-click the lottery pictures, select "hyperlink" and click "bookmark". Select the corresponding slide in it (that is, the slide that just said the award). If this picture is the first lottery number, select the prize corresponding to the first lottery number just now, and click "OK" when showing the slide show, and it will directly link to that prize (don't forget to insert a hyperlink on each prize page according to the previous method to link to the initial page, which is convenient for returning! )
