Do you know any sort of puzzles that can work in the context of a short competition? In other words, puzzles that have these features:
- The premise should be fairly simple to follow (but the solution might not be so simple).
- The puzzle should be engaging and fun.
- It should have not just one, but several correct answers. However, these answers could be rated under certain criteria, like the more optimal one, or more difficult under certain constraints.
- The puzzle outcome could be linked to other puzzles.
