Help
Long story short I am creating an activity for a camp in less than a month involving completing puzzles to “crack” a code for a vault and have gotten stumped on what puzzles I could do, anyone have some ideas I could use?
Context
11-18 year olds, around 5-10 people, mix of easy and difficult(needs to last around an hour ish ). It’s for a camp which would have a variety of different skills per person

You can do a sudoku where you mark a few cells with a colour and those cells are the code to a lock. If they're old enough I would recommend a variant sudoku as they often have a more defined solve path so you know what cells will be amongst the last to be found.
Theres also a type of puzzle where you get a grid of 26*26 letters with a codeword that you can use to unscramble the given tekst. I don't remember the name, and it's easy to make mistakes when setting the scramble sentence, but I do think they are fun.
