June 12: A full house of Unique Rectangles!

[keith]

Hi, Ruud:

Today's Nightmare (Monday, June 12, 2006) has a full house: Types 1, 2, 3, and 4 Unique Rectangles. And then, one more, which is an untyped variant of a Type 6.

I can't believe it! I am usually 2 days behind in getting to Nightmares, if I attempt them at all. I solved this one on my own, without any clues & without resorting to just powering through with contradictions or DICs (until I noticed a rather simple contradiction near the very end). Although I could not tell you the UR types, I did use 3 Unique Rectangles, plus an X Wing. Rudd, I like your UR Themes Week; & I believe such puzzles are improving my solving skills. Thanks.
