Puzzle 60: Insanity

Fillomino Potpourri Follow regular Fillomino rules. In addition, the following variations apply:

– Snake: There exists a snake in the grid, occupying some of the cells. The snake is a non-touching path. The snake passes through all dark gray cells marked S.

– Tapa: Some of the polyominoes are shaded. Note that a polyomino must either be shaded completely or not shaded at all. These shaded polyominoes form a Tapa wall. The wall obey the green Tapa clues: A set of numbers in a light green square with a dim T is a Tapa clue, which tells the blocks of consecutive cells that belong to the wall in the eight squares adjacent to it. Different wall blocks must be separated by non-wall cells.

– Clones: There are two marked 3×3 matrices; one in the top-left quadrant and one in the bottom-right quadrant. These two matrices must be identical without rotations/reflections. This includes whether a cell is a snake segment and whether a cell is shaded (belong to the Tapa wall).

– No-Rectangle: No polyomino is shaped like a rectangle (or square).

Puzzle 57: Ridiculous Changes

Fillomino Operations Divide the grid into polyominoes. Fill each cell inside a polyomino by the size of the polyomino, after applying all mathematical operations it contains (multiplication/division before addition/subtraction). For example, a 5-square polyomino containing -3 and ×2 will have the number 5×2-3 = 7 on each of its cells. Polyominoes that contain the same number may not be orthogonally adjacent.

EDIT: VERSION 5 fajshnkkbkxmidcvger I hope it’s the last update. I’m pretty sure it has a unique solution, but my intended solution requires a really large-scale (as in the whole thing) deduction as the first step. And hence, the expert time is doubled. Whee.

Erm. So I lied and posted a new puzzle before April. This was made while I was doing chemistry finals (after completing it).

Yes, I believe that 6.5/10 is accurate for a 7×7 grid, but I didn’t give this to my testsolvers so I don’t know what the others think. I’m giving this now, and I’ll edit the difficulty/time later after getting responses.

If you find the rules hard to understand, I suppose I should post an example…

Also, did you notice Puzzle 28 and FFF 25 are redone? (The originals were broken and I gave up finding a way to fix them.)

FFF 25: Yet Another Explosion

Norinori Fillomino Follow regular Fillomino rules. In addition, the regions form a valid Norinori grid: It must be possible to shade exactly two squares in each polyomino such that each black square is adjacent to exactly one other black square.

Another out-of-sequence puzzle. The original FFF 25.

Also, it’s great that the original puzzle was broken; I managed to fit a polyomino of size over 4 times the largest given in this puzzle. Yay.

Fillomino Shapes Follow regular Fillomino rules. In addition, the given shapes must appear in the grid, at least as many as given.

Renumbering is a pain. So, let’s make a puzzle that fills in the gap instead.

Here was the original Puzzle 28. Because ksun48 asked for a hard Fillomino variation, I believe that this is sufficiently hard, albeit the easy master target.

Also, yes, I don’t think Sky is going to tell his tale again. Most likely I will rephrase what he’s going to say, just like the paragraph two paragraphs above this.

Puzzle 56: Party Quadrants

Region Party Fillomino This is a hybrid of Clones Fillomino and Extra Region Fillomino. The two blue 3×3 grids are from Clones; they must be identical. The two red 3×3 grids are from Extra Regions; each of the grids must form another valid Fillomino grid.
