It's a nice interface. I'm glad arrow keys, the first thing I tried, work. But you're not going to trick me into looking for a sequence of moves that change the parity of the underlying permutation.
- scrrr 11y agoI just found this article on the solvability of these puzzles: https://www.cs.bham.ac.uk/~mdr/teaching/modules04/java2/TilesSolvability.html https://www.cs.bham.ac.uk/~mdr/teaching/modules04/java2/Tile...
- earendil02 11y agoI wanted to win, so I just changed the goal to P,L,A,Y,T,H,I,S,G,A,M,E,W,O,N, which is solvable ;)
- jcl 11y agoThe game is solvable -- no tricks, just something you've overlooked. (Hint: Someone who doesn't know about parity might try scrambling the puzzle randomly, then find that they can reach the goal state about half of the time.)
- cwilkes 11y agoThat was fun. My usual technique of making a "train" of letters to slide and then attach a caboose didn't work. So I flipped my phone upside down and acted like I wanted to make the word WON at the top. I did then did the rest of th puzzle, finding out the difference from a normal 15 puzzle along the way.
- cokernel 11y agoIs the thing I've overlooked that there are two As?
- joeriel 11y agoYes - easily solvable when you flip the A's
