Warning - Spoilers Ahead
Thanks to the Unique Design of the Quest Puzzle Pages, the majority of the page's rely on other puzzling elements besides just the internal working mechanics so ruining the solution won't be an issue for most except Page 5 which if you do yourself, you will know the answer for the puzzle. I tried to make the last video "Locking It Up" easy enough that you could have a loved one lock it up for you, but if they aren't the best at such things, Page 5 is the one I'd highly recommend they do for you at the bare minimum as it really isn't hard to lock up at all.

The Assembly Videos will show you how best to put your book together, but you do need to watch carefully follow along and pay close attention to the orientation of various pieces and magnets in order for your book to work correctly. Before attaching and locking up any of the pages together, make sure you can still unlock the page with your intended solution.
