Looking for puzzle ideas

[GrandPotentate]

I am working on putting out a series of caches that revolve around somewhat difficult puzzles, either in the field or at home. My most recent puzzle is a field puzzle that required the cacher to get a ball through a maze build inside of an ammo can, the can is locked and so there is the difficult part. I have a couple more ideas for future puzzles, but it never hurts to get more idea that could spark a totally new puzzle.

 

Some puzzle ideas of my own:

- Sudoku puzzle with highlighted boxes that will complete the coords

- 3-d interlocking wooden puzzles with number all over and need to put the puzzle together to get the right numbers

- popsicle sticks that must be lined up properly to get the coords

- coords in white font on description page with a set value added to each digit

Here is one of mine. http://coord.info/GC2HK35 it is fairly simple to solve once you figure it out.
