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.

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.

FFF 8: Fillocity is Back

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.

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.

Skyscrapers Fillomino

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

FFF 3: The Isolation

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.

FFF 2: The Guards

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.

Sentry Fillomino In addition to the regular Fillomino rules, if two numbers in the same row/column are equal, they must belong to the same polyomino.

The guards are really incompetent! They make a puzzle that is easier than Sky’s currently easiest puzzle here.

Fillomino Divide the grid into polyominoes and put a number in each cell indicating the area of the polyomino it’s contained in. Two orthogonally adjacent numbers are equal if and only if they belong to the same region; in other words, no two regions of the same size may be orthogonally adjacent.

Sky has committed himself to a rather time-consuming project of constructing Fillomino puzzles for the entire February. Can he keep up with the deadlines?

Puzzle 6: Antisymmetric Light Bulbs

Akari Put some light bulbs on the cells of the grid. Light bulbs illuminate all squares in the four orthogonal directions (up, down, left, right), up until reaching an edge of the grid or a black square. Illuminate all squares, but no light bulb may illuminate another light bulb. A number on a black square determines the number of light bulbs orthogonally adjacent to it.

Puzzle 6: Antisymmetric Light Bulbs
Akari

We interrupt the IMO 2012 series for this post and the next post.

Yay for puzzles. Guess I’m back at “logicsmithing”.

This one is a pretty easy Akari. However, the aesthetic part of this puzzle is rather high by my standards. Opposing givens add up to 3, just like some Slitherlink I’ve seen…

*went browsing for like 30 minutes*

Oh hey I can’t find that puzzle. Whatever; it means I can make it some time soon and claim it as the only one in the last [insert a small time interval (less than a year)] 😛

Whatever. Akari, 10×10. Would go to an easy or something. Did I repeat myself?
