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!

Puzzle 13: Prime/Composite Fillomino

with 6 comments

This is a fillomino with the extra restriction that all prime-sized regions are contiguous and all composite-sized regions are contiguous (1s don’t matter).

Notes: Thanks to Cy Reb, Jr. for the original concept.

I think many more cool things can be done with this kind of variation (several groups of polyominoes needing to be contiguous), and this puzzle isn’t very interesting when it comes to creatively using the condition, but I hope you all enjoy it anyways.

Puzzle 12: Total Yajilin

with 7 comments

This is a Yajilin puzzle with a small twist. Each clue number is now equal the total number of black squares in the same row and column as that clue number (this means I don’t have to draw any arrows, yay!).

Notes: This is pretty much MellowMelon’s Indirect Yajilin, but I figured that it wouldn’t exactly be accurate to call this puzzle Indirect when it only uses clues of this one type. And, of course, putting grey plus signs in the cells would be a very difficult task for me.

Also, on a more personal note, I haven’t constructed anything in the past month mainly because of college apps. However, I submitted my early action applications to MIT and Caltech yesterday, which means more time for puzzles! 😀 Though I suppose it would be a good idea to force myself to construct at a rate of two puzzles per week or something so there aren’t any huge time gaps between postings.

Puzzle 11: Fillomino (no rectangles)

with 5 comments

This is a Fillomino puzzle, with the additional rule that no region can be a rectangle.

Notes: Original variation idea by mathgrant.

I also wish I could create puzzles more frequently, but this past week has been hell studying for the SATs. Oh well.

Puzzle 10: Line Nurikabe

with one comment

This is a Nurikabe puzzle with a twist. You are now allowed to have 2×2 squares of black cells, but you may not have 5 consecutive black cells in a row or column. Credits to MellowMelon for creating this variation (or, at least, for posting the first line Nurikabes I’ve ever seen).

Notes: Yeah, so I haven’t posted a puzzle in a week or so. This was mainly due to participating in the Microsoft Puzzle Hunt last weekend, and then having my parents yell at me for not getting as enough essays done as they want me to, and then just losing my motivation (college applications…darjn). Anyways, I hope you like this despite it being non-symmetric.

By the way, if you haven’t seen the Microsoft puzzles, they’re here. It was awesome, as pretty much all of the individual puzzles were very nice and elegant, and some just blew me away (such as The Social Network and Codebooks). The “meta”s were kind of disappointing, in that they didn’t actually use any of the puzzle answers, but that didn’t detract from the overall enjoyment.
