Puzzle 22: Nurikabe (pairs)

with one comment

Rules from MellowMelon’s blog: This is a Nurikabe puzzle, with a twist. Every region of unfilled cells must contain exactly two numbers (instead of one) and have total size equal to the sum of the two numbers.

Notes: After a 3 month break, and thanks to a 2-hour long physics class, we’re back. 😀 Also, there’s no hidden valentine’s day theme or anything (I didn’t even know that it was valentine’s day until I saw students carrying around flowers today, heh). The 2s are, well, for puzzle 22, and feel free to count how many 2s there are.

On another note, I might post a more detailed mystery hunt recap sometime. Out of the logic puzzles I remember, Portals was amazing, Agricultural Operations was cool, A Regular Crossword was cute, and Random Walk was okay but had lots of trial and error. Palindrome was an awesome team to solve with, as usual!

Puzzle 21: Skyscrapers Fillomino

Rules (from the Fillomino-Fillia 2 booklet): In addition to the usual rules, the numbers in the grid should be treated as building heights. Numbers on the outside of the grid tell how many buildings are visible when looking from that direction. A building obscures all buildings behind it whose height is equal to or smaller than itself.

Notes: This puzzle is brought to you by the numbers 1, 2, 3, 4, and 5.

If you haven’t done Fillomino-Fillia 2 yet, there’s still time! You can still start the test any time in the next 3 hours or so. And even if you don’t plan on competing, you should definitely do the puzzles afterwards, because they are amazing.

Puzzle 20: Fillomino (no row/column repeats)

This is a Fillomino, with the added rule that in any row or column, all cells with the same number must be part of the same region. In other words, no two regions of the same size can share any row or column.

Notes: With three puzzles in three weeks, it seems like this blog might actually be revived after all. 😀

Also, in case you haven’t heard, Fillomino Fillia 2 will be held at LMI this weekend, and it’s definitely going to be awesome, so everyone reading this should do it! I might create and post some practice puzzles this week if I have the time.

Puzzle 19: Looking for the Loop

Instructions (taken from the WPC): Draw a single closed loop in the grid by connecting horizontally and vertically neighboring cells. The loop can touch itself, but it cannot cross or overlap itself. Cells with numbers cannot be parts of the loop. Each number in the grid indicates how many of the eight neighboring cells are used by the loop.

Also, in this puzzle, the loop cannot go through any squares with an X (yeah, I know it’s sort of inelegant; looking for the loop is quite a bit more difficult than tapa-like loop when it comes to uniqueness).

Notes: I am currently attempting to stick to a one puzzle per week schedule. Let’s see whether I keep my promise next Monday/Sunday!

Notes: Last week, I went to the 21st World Puzzle Championship as part of the unofficial U.S. B-team. I might write more about it later, but for now, I’ll just say that it was an awesome and inspiring experience and that it was great meeting so many people in person.

I haven’t constructed puzzles in a while, even though I definitely have the time to do so. There was a round at the WPC based on the number 21, so I figure that this puzzle will be good for getting started again.

Puzzle 17: Fillomino

This is a normal Fillomino puzzle.

Notes: chaotic_iak said that he wanted some Fillomino, so here you go. It’s a good thing too that chaoticiak has 10 characters! 😉

Of course, I am still (and will probably always be) accepting requests for puzzles/variations anyone would like to see.

Puzzle 16: Tapa-Like Loop

with one comment

Some preparation for the upcoming Tapa Variations contest at LMI.

Rules (copied from instruction manual): Tapa wall is in the form of a continuous loop. Clues inside the grid represent the number of neighbouring cells visited by the loop. If there is more than one number in a cell, each number should be represented with a separate loop segment. In this puzzle, no 2×2 rule of Tapa does not hold.

Notes: I really should start posting on a regular schedule. Again, I’ll say that if anyone has any requests for puzzles they want to see on this blog, just leave a comment and I’ll try my best.
