I am afraid you are on your own. Livecode is programming, now you would have to try to program timer and high score.wondering if the game can have a high score table and timer, If so could I please see the code for the score and timer fields?
I just wanted to make shure you got a working copy of the 8-puzzle game. From there you start to modify it. But in order to modify it you will have to understand the 8-puzzle game first.
Klaus also posted a link to the conferences. That is an excellent starting point to get into Livecode.
KInd regards
