Is there a specific reason necessary to make a puzzle highly symmetric and has many 5s? Sky said no.

Sky put the restriction that there is no rectangle polyomino in this puzzle. Ironically he put a rectangle from the givens; a diagonal one. Well, why not?

Snake Fillomino

Sky had built a small garden at the backyard, and was surprised to find a snake this morning circling the garden. For whatever reason it inspired Sky to make a puzzle of that theme. Don’t ask me how he got insane inspirations.

Large unfilled areas always somehow mesmerize Sky. Now Sky put two of them at the price of making the rest pretty constrained. Still a good puzzle for him at least.

Nurikabe Fillomino Follow regular Fillomino rules. A polyomino may only have at most one green square, and no two polyominoes containing green squares may touch orthogonally. Afterwards, shade the polyominoes not containing any green square. The shaded cells must form a single polyomino but may not have a 2×2 shaded area anywhere.

Weird. Is the stream of size 32 or is the island is the one that is of size 32? Either way, Sky was a little bit hyped when he got the inspiration of this unusual puzzle.

Easy As FillominEO Follow regular Fillomino rules. A number outside the grid gives the first even/odd number encountered from that position going into the grid along the row/column. (Of course, if said number is even, then it’s the first even number, and if said number is odd, then it’s the first odd number.)
