If you have a chance to get lockboxes and locks to make physical escape rooms for your students it is a total blast, but takes time to set up. I tend to create my escape rooms in a sequence, questions in level 1 will give you the clues to unlock the next box and access the level 2 questions. This is repeated until your students make it to the end and "escape". When making a digital escape room I follow that same sequential format, but I have seen so many other creative ways educators have made these work for them. I use Google forms to make my escape rooms because I love my Google Drive Apps, but you can just as easily use Microsoft Forms.
When creating the escape room visualize the various sections of the digital form as different "rooms" to escape from by solving various tasks. Start with the check-in room where you get your student's name and then build a new section. The new section will have the first series of clues that lead to the discovery of a code to unlock the next level or section. You can use videos, pictures, reading passages, etc as the means of sharing the clues with the students. I am far less creative than others, so I just use 4 multiple-choice review questions that lead to a cipher key or logic puzzle that provides the 4 digit code to unlock the level. You will use a short response style question in the digital form that is formatted to only accept a specific answer ( the code) before the participant can move on. This is pretty hard to explain in writing, so below is my tutorial video where I show you exactly what I am talking about and what this all looks like.
