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 (adapted from Nikoli)

  • Fill in all empty cells with numbers under the following rules.
  • Numbers should be grouped together into 'blocks' of orthogonally connected cells in which each cell contains the same number.
  • The total number of cells making up each 'block' equals the value they all share (e.g. a block of two 2's, three 3's, etc.).
  • Different 'blocks' of the same size and value cannot border each other, horizontally or vertically (but may touch at a corner).

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:

Then,

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.

    @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. – Deusovi Mar 05 '20 at 23:26
