I believe I have invented** a new type of puzzle...

What is its name?

enter image description here

Begin by solving the Fillomino puzzle:

Rules of Fillomino (taken from Nikoli)

  • Fill in all empty cells with numbers under the following rules.
  • Divide all of the board into blocks. Fill each block with the same number horizontally or vertically.
  • Each block contains as many cells as the number in the block.
  • Same sized blocks cannot touch each other, horizontally or vertically.

Then apply some (!) and discover its name! Answers which explain the deduction process are appreciated even more - thanks!

** NB After creating this puzzle, I realised that @Reinier has created something with similar inspiration before, but I believe our two puzzles are sufficiently different... Try to resist peeking at their puzzle before solving this one! :)

First, the Fillomino should be solved:

all of the blue shaded cells are numbers from 1-3. This can be solved as a Slitherlink:

And finally:

The letters the loop passes over (clockwise from the top left)...

...spell FILLERLINK.

    $\begingroup$ @StephenR In the original puzzle, some cells are shaded blue. Those numbers only can be copied to a new grid, and then solved as a Slitherlink. $\endgroup$ – Deusovi Mar 5 at 23:26
