Puzzle 20: Fillomino (no row/column repeats)

leave a comment »

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

with 5 comments

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!

Puzzle 18: Slitherlink

with 2 comments

This is a normal Slitherlink.


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

with 2 comments

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.

Puzzle 15: Shortest Segment Tapa

with 3 comments

Rules, from the Tapa Variations Contest X booklet: “Follow regular Tapa rules. Additionally, clues outside the grid indicate the length of the shortest blackened block lying towards that direction.”

EDIT: As pointed out by Bram, the recently released errata on the LMI site means that this puzzle has different rules from the one on the test. For this puzzle, if a number appears on the side, then at least one segment of that length must appear in that row or column.

Notes: I’ll probably make some more tapa variations by Saturday. Don’t forget about this if you want practice for braille tapa!

I’ve also pretty much given up on sticking to any sort of puzzle creation schedule. Maybe I just need more motivation, though, so I will now be taking puzzle requests :P: if anyone wants me to try creating any kind of puzzle, say so in the comments and I’ll get to it.

Puzzle 14: Number In Order

with 6 comments

This is a Number in Order puzzle, originally created by chaotic_iak to the best of my knowledge; see here for the rules.

(yay pi)

Notes: Has it really been over 2 months? Man, that’s a really long time. My only excuses are college applications, homework, and laziness, but I really ought to construct more, just because the process is so fun. I don’t want to make any hard schedule, but I’ll definitely try to make at least 1 puzzle a week from now on.

Anyways, this puzzle may be on the hard side, but it can be solved using direct logic. I think this puzzle type does have potential for some pretty fun deductions and variations, though I’m not sure how far it can actually go.

Finally, and most importantly, I’ll be headed off to Cambridge in a few hours to the MIT Mystery Hunt this weekend. I’ve been looking forward to it for about the past 362 days, so it’s pretty exciting. Hope I’ll see some of you there!
