I've seen puzzles like those, but haven't tried them. You'd have to choose the dingbats carefully because most of them are too hard to draw.

A - I would be OK. Dingbats or colors would slow it down considerably, for me at least. The difference is when I look at a group (either a row, a column, or a 3x3 sub-square), how long does it take to determine which of the nine numerals is missing? Not long at all ("OK, I still need 3, 4, 5, and 8 in that column"). Probably the same with letters. But with colors or symbols, I expect I would never get the "missing" ones as fast as I get the numbers. Of course that wouldn't make the deductive process of solving it harder, it would just take longer to go through everything. The Sudoku game I have on my phone has a timer and I usually finish in 5 to 15 minutes depending on how hard they are.

Of course people would work the puzzles faster if they weren't dingbats. But most people are.

:D

How about A to Y?

I would like to try the Times of London's Samurai, but my laser printer at work refuses to figure out how to do the tiling to print it.

Trouble is it all starts to get out of hand - already we have a world champion - and take a look at some of the puzzles she solved ! (adobe download)

My lady gave me a Sudoku book that I worked on when I flew to California in November. I liked it a lot...unfortunately, I haven't looked at the book since.

Well this site is not dingbats and not numbers, but is pretty cool. The biggest puzzle is only a 6X6 grid. I find it pretty easy but I have been doing these sudoku puzzles a lot(I have a lot of spare time at work).

My mom gave me a Sudoku book for Christmas. I was hooked for the first day. Then she stole it, and I haven't seen it since, therefore ending my addiction.

But, to answer the question of the first post: Honestly, I have no idea. It might be the sense of accomplishment when you finish one. It might also be the fact that it makes you (or at least me) feel smarter when I finish one faster than the one I did before it.
