This is a Nurikabe puzzle, with a twist. Some numbers have been replaced with letters. Same letters represent same numbers, and different letters represent different numbers. The assignment of letters to numbers is up to you to determine.

This is (probably) not a return to the weekly posting yet; it’s a one-off I made before the WPC and wanted to post.

When a call for making a puzzle to decorate the US team shirt went out, I made this, while motris made this. As can be clearly seen I wasn’t thinking a whole lot about aesthetics in making mine, so there was a clear deserving winner for getting put on the shirt. Still, the puzzle came out well and is worth posting.

On another note: is everyone else seeing the gridlines as not showing up in the scaled thumbnail above in a very ugly way? It happened to Space Probes in my USPC set too. Geez, after over 3 years this is the first time I’ve been really upset with how WordPress is treating me.

This is a Nurikabe puzzle, with a twist. It is not allowed to have five consecutive black cells in a row or column. The usual Nurikabe restriction that there can be no two by two squares of black cells is waived and no longer applies.

Puzzle 407

Sorry for the unannounced break last week. A second Wednesday puzzle will be posted 12 hours from now to compensate. My summer work is winding down now, so I hope to avoid having to do this again in the near future.

This is a Creek puzzle, with a twist. One of the grid squares has treasure in it, though its location is not given. A number in a grid cell gives the length of the shortest path to the treasure going through adjacent unshaded cells. The path length is computed as the number of grid cells used, including the two cells with the clue and the treasure. Cells with a number or treasure are unshaded.

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.

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 Some numbers have been replaced by letters.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.

Puzzle 400

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…

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.

Puzzle 389

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