Clue Matching Game

Okay this one is a bit weird and to be honest we haven't yet finished this clue matching game because its very big! The general idea is that a crime has been committed and you need to score enough points to identify the murder weapons, get clues and interview suspects. You achieve this by matching up three or more similar clues on the grid. You do this by clicking on two similar clues and they swap places. If they then form a line of at least three either horizontally or vertically they disappear from the grid and new clues come into view. Do this quickly enough and score bonus points.
