For the time being, it looks like I'll be abusing LiveJournal's own Scrapbook feature in order to get my puzzle images back up, but it definitely feels like a kludge and will likely be reworked once I encounter a better option. I also have to recreate the scaled-up puzzle images one at a time, so this will take awhile. On the plus side, it has given me the opportunity to revisit the scaling method; I'm now using a hybrid (I wish I'd thought of that sooner) that should keep both the retro-pixel feel and soft egdes without being so blurry on non-CRT displays (such as on paper...). I'm also tagging the puzzles by type as I go. As I'm typing this, only Puzzle 1 is done - tell me what you think of the new style (it's not too late for me to change it...).
ObTeaser: Consider a 3x3 Sudoku grid with the minimum number of givens needed to make it uniquely solvable (which would be 2). Now strip it of its regions, so we are left with a 3x3 Latin Square with givens matching the Sudoku in corresponding cells. That Latin Square will be uniquely solvable if and only if... Finish that sentence. - ZM
