Puzzle Script

I am trying to create a word puzzle and would like to know if there is any script available already. If not what are the tips of creating a puzzle using the LSL script. Kindly help me to create the puzzle.

It is rather difficult to help with so little information-- what sort of puzzle do you intend to create?

To place Letters on a Prim and change them via scripting, try this:

Lets say create a 10 x 10 grid square and answer some questions or phrases inside the grid. This a word puzzle that will allow the insertion of words either horizontally or vertically. Lets say the user click a square and select letter "A" if that letter is not the one suitable for that square it will not allow the user to place that letter until he or she finds the suitable letter. I just want to experiment in second life on create a very simple word puzzle of that nature. Anything closer to that will work.
