This escape room plan from Teaching Ideas has pretty basic materials, or things you can buy inexpensively. They lay out all the clues and how to set it up.
The puzzle has six clues but you can always add more if you want it to take longer. The whole setup is described on the blog post, and you can subscribe to get all the printables and instructions. Check out the post at Teaching Ideas for all the details!
