This is a Shape Fillomino puzzle. This variation was created by Palmer Mebane.
Rules (from Grandmaster Puzzles):
Standard Fillomino rules. Also, the shapes shown [next to] the grid must appear as polyominoes in the grid. Shapes may be rotated, but may not be reflected.
Very nice solve. Of course I didn't get the main argument at first, but that just makes it better when I do find it.
ReplyDeleteI missed the no-reflection rule, and don't think I had to use it.
Thanks for your comment!
DeleteI too missed the no-reflection rule when writing the puzzle, and only came across it when posting the rules above. Luckily, none of the shapes were reflected in the solution!
