Friday Puzzle #62 - Polish Pentomino Crisscross  
(Note for next week: Friday Puzzle #63 will be constructed after the release of the USPC instructions. I will complete my USPC preview post with a poll including all the puzzle types in the morning/afternoon. The winner of a vote by ~4 PM PST will then be constructed and posted as the Friday puzzle. I'm hoping to have to draw two mice-based images since I've never constructed such a task, but who knows what the democratic process will select as the most interesting puzzle to see beforehand.)

The Tetris Crisscross was an interesting puzzle from 2006 but unfortunately, without any rotation/reflection of the tiles, and with all placement locations given, seemed a bit too easy for its potential. I decided to take this style to another level with a few modifications in this Pentomino Crisscross. Since many USPC's often have a puzzle themed for the WPC host country, I used Polish city names (minus diacriticals) for my word list.

Rules: Place all the listed words into the grid crisscross-style (ignoring spaces) so that no other words are formed. The 12 pentominoes below the grid must also be inserted into the grid with rotation and reflection allowed. Pentominoes can touch, but cannot overlap. The numbers on the right and bottom of the grid indicate how many pentomino cells belong in that row/column. Notice that the pentominoes contain some shaded squares and some vowels; all of the shaded squares are given in the grid and none belong in words, but all placed vowels from the pentominoes will be used in words.

Thought I'd give this a go to brush up on my CC skills. Really liked it but not quick for me (just shy of 25 minutes). I did try to do it logically though and it might have fallen quicker if I'd gone to pencil/eraser early. I also had a couple of brain farts (including being convinced I couldn't place a longish entry near the end, which was just retarded). BTW I forgot to comment but your Wolves in Sheep's clothing puzzle from a couple of weeks ago was awesome.

Re: CrissCross
In practicing my own puzzle, I thought it possible to logic from the first word forced on the left side to the middle column with all the pieces and then ID that column completely. Once that is done its a pretty simple crisscross. Still, it is a long puzzle and longer than any typical USPC challenge so 25 minutes isn't too shabby. Good luck with the test next week (presuming you'll have time to take it).

Re: CrissCross
Alas a friend has been inconsiderate and decided to get married that day so I can't do it 'live'... looking forward to doing it over the weekend though.

I liked this one, and got through it logically. My slow start perhaps reflects some inexperience with pentomino puzzles. Thanks for the practice!
