I have considered adding "organic chemistry escape room" games to my Organic Chemistry courses and I want your help!

I would like you to design one escape room puzzle, based on topics covered in this course. The puzzle should require the students to use knowledge from this course to solve the puzzle and I$\text{'}$d like it to take them at least $2$ minutes to solve.

If you're not familiar with online escape rooms, the basic idea is that if they solve a puzzle correctly, they will get some letters or numbers, which can be used to unlock the next puzzle. I've shared some ideas below. Please do not feel limited by this list of puzzle types, you can be as creative as you'd like!

Crossword puzzle with some letters being circled. The circled letters then can be put in order $($just make sure its clear how to do that$),$ which gives them the "code word" to unlock the next puzzle.

Student must find the products to a series of reactions. The possible products are in a "bank" and each product is associated with a letter or number. The order of the letters or number leads to a code word or number to unlock the next puzzle.

Students must name compounds and they are told to circle a certain letter in the word $($the third letter of this name, the $8$th letter of this name, etc$).$ Those letters are the code word or number to the next puzzle.

This assignment is worth $10$ bonus points, towards your final exam grade. To get full points, you should submit your blank puzzle. Then you should submit the answer to the puzzle. Please do not copy your puzzle from an outside source, this will result in intentional plagiarism charges.
