RE: Slide puzzle question
I don't know about the 9 puzzle but I suspect it's like the 15 puzzle. The 15 puzzle and Rubics Cube have parity. If the 15 is out of parity it can never be solved. The same for Rubics Cube, if you say switch 2 edge pieces or rotate 1 corner piece it's not solvable.

Re: Slide puzzle question
I'm not sure whether there is an answer in terms of pieces in place/out of place. I know that there are (I think three) different "position-spaces" where each space is unreachable from the others. The easy solution is to this problem is to start with the puzzle solved and quickly execute thirty or so moves at random, either visibly or with the screen locked. gc > On Mar 7, 2018, at 6:40 AM, William de Smet via use-livecode > wrote: > > Hi there, > > I am making a 9 piece slide puzzle. > How many pieces should be in the right place at start to solve the puzzle? > > > > greetings, > > William > ___ > use-livecode mailing list > use-livecode@lists.runrev.com > Please visit this url to subscribe, unsubscribe and manage your subscription > preferences: > http://lists.runrev.com/mailman/listinfo/use-livecode ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
