Image Reveal

Well yes but more info needed. Do they have to progress in a certain way? i.e. Can they reveal the pieces in any order or is there a specific order?Putting all this on one page is going to get very messy from a developer standpoint. Better to create a section with the key object(s) at the section level. I am guessing since they enter the key, the key is letters. Put it at the section level - each part in a separate box initially not visible. Have one action at the section level for each part that says on show, show the part if the related question is correct. Have one question on each page in the section. When the question is answered correctly, show hide a piece of the key and got to the next page. The section level actions will show the parts already answered correctly. You did not say what happens if they answer the question wrong. Any feedback other than part of the key was not shown?Now this whole time, it looks to the learner like they are still on the same page if you don't have page numbers.On the last page, have a fill in the blank question. Your check my answer button checks the key entered. If correct, goes one place. You will need another action that takes them to the review if the key is not correct.Does this help?
