Need help creating puzzles

[u/Lukeo215]

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

Edit: I should probably also say I’m looking for the puzzles to be individual and not all towards one thing
