You could reach the answer with 7 moves (or any n really) if some moves were transpositions. (Ie. Keep moving the D around until you have 4 moves left). I agree that it's a questionable inclusion.
A possible improvement would be making sure that the solution is reached by the minimum number of moves.


After reading the discussion regarding the Matchsticks puzzle I think I missed a couple of aspects during the test.
I think the rule that each matchstick can be moved exactly once needs to be specified explicitly. Otherwise with transpositions you are right that the target can be achieved in any number of moves.
I had a specific solution in mind which like Ivan pointed out can be achieved in exactly seven moves.

In hindsight there is also room for improvement of the answer key which should possibly be asking for information about which matchsticks are being moved and to which location.

Without this kind of answer key and the explicit rule to restrict transposition I agree with your recommendation about asking for a solution which is reached by the minimum number of moves.

I really enjoyed the word puzzles, those were the fun part of the contest. Also, the casual puzzles were fascinating because time taken to solve them was non-linear :D

Don't know about matchsticks - they kinda seemed like guesswork for me. Loved the word puzzles though.
