FFF 14: I and U…err…E and O

Fancy Fillomino February: This is a series of 28 (twenty-eight) 7×7 Fillomino puzzles over the February. Every 00.00 UTC+7 a new puzzle will be up. The basic Fillomino rules apply unless otherwise indicated.

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.)

(A sequence is nondecreasing iff each number is less than or equal to the next number in the sequence.

Nondecreasing Fillomino

First feature of the natural landscape. Inspired from the cliff-y and large Icerock Mountain, Sky made a puzzle where a step means a climb. Sky challenges you; can you reach that 13?

Full Kropki Fillomino In addition to the regular Fillomino rules, the numbers must also satisfy the Kropki clues. A black circle is always between two numbers, one of which is exactly twice the other. A white circle is always between two consecutive numbers. All circles have been given.

FFF 10: Black Deja Vu
Full Kropki Fillomino

Hasn’t this been done before? Well, while the former one uses quite a bunch of black circles, this one uses only a few. Probably because of the grid’s size…or maybe because of the fact that this is full, aka all circles given. Yeah, Sky found something neat to do with the circles, or the absence thereof.

FFF 9: Sandwiches

Fancy Fillomino February: This is a series of 28 (twenty-eight) 7×7 Fillomino puzzles over the February. Every 00.00 UTC+7 a new puzzle will be up. The basic Fillomino rules apply unless otherwise indicated.

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

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.

Skyscrapers Fillomino In addition to the regular Fillomino rules, the numbers must also satisfy the Skyscrapers clues. If the numbers are interpreted as buildings of said height, a number indicates the number of buildings visible from that position looking into the grid in the corresponding row/column. A building is visible if it’s not behind another building with equal or greater height.

Well, the mayor of Fillocity somewhere outside Manne asked Sky. Again. This time it’s not something insane though.

Fancy Fillomino February: This is a series of 28 (twenty-eight) 7×7 Fillomino puzzles over the February. Every 00.00 UTC+7 a new puzzle will be up. The basic Fillomino rules apply unless otherwise indicated.

Fillomino Tapa Follow regular Fillomino rules; ignore the green numbers and suppose that they are simply obstacles in the grid (like an empty hole that doesn’t have any number in it). Afterwards, shade some polyominoes black such that the shaded polyominoes form a tapa: They must form a single polyomino, but there may not be any 2×2 square that is all black. The green numbers are Tapa clues: Each number gives the number of consecutive black cells around the 5 squares orthogonally/diagonally adjacent to it.

Sky loves experimenting. By whatever insane thoughts, Sky managed to cross from Fillomino to Tapa, and got the amazing idea of making a hybrid of them. Is it well-executed? Well, this is an example…

FFF 6: LITS or LIST?

Fancy Fillomino February: This is a series of 28 (twenty-eight) 7×7 Fillomino puzzles over the February. Every 00.00 UTC+7 a new puzzle will be up. The basic Fillomino rules apply unless otherwise indicated.

LITS Fillomino Follow regular Fillomino rules. However, replace each polyomino of size 4 (tetromino) with one of L, I, T, or S, depending on its shape (each letter somewhat resembles the shape, but just in case (consider rotations and reflections as equal)). These tetrominoes must follow the rules of LITS; that is, they form a single polyomino, but there is no 2×2 area completely covered by these polyominoes (hence why there is no O tetromino), and no two identical tetrominoes are orthogonally adjacent (rotations and reflections, again, are equal).
