Puzzle 416 (Tapa)

November 17, 2012

This is a Tapa puzzle.

The theme is because I turn 23 today. I also recently learned that this is deu’s birthday too; you may know him as a top solver at LMI/WPCs/nikoli.com.

Well, I suppose that mathematically the chances of two active competitors having the same birthday is pretty high. Even so… this does not feel like your typical pair. Apparently the puzzle gods decreed that people born on this day would enjoy nikoli-style puzzles and be very quick at them.

IPC 2012 Puzzles

June 6, 2012

Last weekend, the 2012 Indian Puzzle Championship was held at LMI. Like last year, I provided some of the puzzles for it, alongside Deb Mohanty, Serkan Yurekli, and Thomas Snyder. Six out of the 30 puzzles were mine; I’ve reproduced them in this post for anyone who hasn’t seen that championship. Enjoy.

Puzzle 400 (Tapa) [Cipher]

May 9, 2012

This is a Tapa puzzle, with a twist. Some numbers have been replaced by letters. Same letters represent the same number, and different letters represent different numbers. 0s may not appear in multi-number clues.

I graduate from the college spelled down the main diagonal on Sunday. And by the time next week’s puzzle is posted, I will be on a plane with a final destination of Saudi Arabia for a brief stint of work. I’ve given myself a pretty packed schedule this summer…

TVC XII Practice Pack Addendum

March 29, 2012

Here’s the last of my TVC XII practice puzzles – see the previous post for the others that I made. The two puzzles in this PDF are examples of Broken Tapa (5) and TAPA TAPA (10), which I promised a few days ago.

As you might be able to tell from the timing of this post, I probably wouldn’t mind if LMI did Tapa for a third month, whether I was putting up good results or not.

TVC XII Practice Pack

March 25, 2012

TVC XII, the last of the four Tapa Variations Contests this year, is being held next weekend. For most of the TVC’s this year Para has posted practice puzzles for the types on his blog. This time around one of two things is going to happen: either you’ll get two sets of puzzles, or Para will get a well-deserved break. That’s because I had a lot of time on my hands this weekend.

TVC XII practice pack (PDF)

This PDF contains practice puzzles for Twilight (2), Compass (3), Wired (4), Roman (6), Sweeper (7), Loop (8), and two puzzles for Borders (9). We’ve already seen Visionary and Make Room (1) in the TVCs before, and I plan to make Broken (5) and TAPA TAPA (10) later. In the case of Twilight and Borders, these are variations I have done on the blog before, so the PDF just includes those older puzzles (351 for Twilight, 382 and 388 for Borders). The other five were just made.

Puzzle 389 (Tapa) [Regional]

February 22, 2012

This is a Tapa puzzle, with a twist. Each clue functions not only as a normal Tapa clue but also serves as a clue for the region it is contained in, giving the size of each contiguous block of black cells in the region. Each region contains at most one clue, and there are no constraints on regions without a clue.

I’ve been surrounded by so much Tapa lately that I can’t help but think of more ideas for it…

Puzzle 388 (Tapa) [Borders]

February 15, 2012

This is a Tapa puzzle, with a twist. The borders between some cells may be either thick or nonexistent. A thick border separating two cells means one is shaded and the other is not. A lack of a border means the two cells are both shaded or both unshaded.

The borders idea seems close to being able to stand on its own without any Tapa clues. I’m sure such puzzles can be made, but I don’t think it would have the kind of depth I want in a type.

Puzzle 382 (Tapa) [Borders]

January 4, 2012

This is a Tapa puzzle, with a twist. The borders between some cells may be either thick or nonexistent. A thick border separating two cells means one is shaded and the other is not. A lack of a border means the two cells are both shaded or both unshaded.

Puzzle 381 (Nurikabe/Tapa) [Mastermind]

October 30, 2011

This is a Nurikabe / Tapa Mastermind puzzle. Solve the left grid as a Nurikabe and the right grid as a Tapa. The gray numbers between corresponding rows represent Mastermind clues. If one were to superimpose the two solutions (without rotation or reflection), the gray number in a row tells exactly how many squares are shaded in both grids.
