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

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

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.

Sandwich Fillomino Follow regular Fillomino rules, but blacken exactly two squares in each row/column. These black squares don’t have numerical values (in particular they may be adjacent to any other number including other black squares). A number outside the grid gives the sum of the numbers between the two black squares in the row/column.

Sandwich Fillomino

sandwich n. two or more slices of bread or the like with a layer of meat, fish, cheese, etc., between each pair
sandwich v. to insert between two other things
(Dictionary.com)
Sky is fond of sandwiches now, but he was somewhat surprised when he discovered another meaning of sandwich (and even more when he found five in Dictionary.com). He makes this puzzle to attempt to put the second meaning of sandwich above in action.

A building is visible if it’s not behind another building with equal or greater height.

Consecutive Fillomino

Sky finds it hard to believe that one of the kids from the local kindergarten has no friends just because “he’s odd”. So Sky makes this puzzle to show that everyone else is odd, not him, and also that he can make friends by finding similar people to him. What a story.
