Nintendo DS
The New York Times prints mind-boggling crosswords, with clues both vague and ambiguous. The DS version makes my head feel like a brain-leaking sieve.
A clue for one of the 1,000 puzzles in the game is "old-fashioned"; the answer to that riddle is "horseandbuggy." Really? I'm supposed to guess that?
The game is fun, if you like masochism. And fortunately, it does give you a choice to play easier puzzles. "Monday" puzzles are the simplest, and each day after that gets progressively tougher.
Sunday puzzles are ridiculous. Here's a Sunday clue: "title village in a 1979 Francesco Rosi film." The answer: "Eboli." (I missed that.)
There is one saving grace: You can press a "hint" button on the DS, and the game fills in as many letters of an answer as you want. You could "hint" and cheat a whole puzzle or just the sticky spots, to keep annoyance at bay.
