The traumatic brain injury incurred by bashing your head against walls makes that increasingly unlikely.

I don't understand whence this fad has come. I mean, I've been doing Number Places for years! My mother and I have nearly gotten into fisticuffs on airplanes to see who gets to do them in the large puzzle books! And all of a sudden we're ahead of the times? What is this?
I love them and I can almost always finish them.

I don't want to think about that sort of thing right now, but it looks like fun for anyone who likes logic-y puzzles.

I am hooked. I have been playing at the site Mike linked to for the last hour, and have successfully solved puzzles at the easy through hard levels. I'm trying my hand at evil now, but it's not going so smoothly.

Yikes, I didn't mean to create another addict.
I've been doing the medium difficulty trying for time. Easy is too easy. And hard takes too long. I haven't really tried evil yet.

I've got like eight books, and I've been creating addicts left and right. But one of the books has something called bridge-puzzles, where you're given various numbers in a circle, which is referred to as an island, and the number in the island indicates how many vertical or horizontal bridges that island has to another island with a maximum of two bridges between the same island. I canNOT figure those ones out. Does anyone have any tips?

I eventually finished the evil puzzle, but I needed a little help in the beginning from the "how am I doing" button. Now I'm just having fun with the medium ones.
I must get myself a book of these, they are such a great time passer.

Holy Cow, I solved an easy on my 3rd try. It took me that many times to get my plan of attack formulated. Now I think I'll be faster...

It's still takes me about 11 minutes per puzzle. I improve my system every time though. I'll be here for a while.

I got hooked on these about a month ago. I can usually do an easy puzzle in about the 3:20 -- 3:40 timeframe and a medium in about the 6 to 8 minute timeframe, but with the hard and evil level puzzles I am usually well over 30 minutes and often over 50 minutes. I've been reading up on the math involved and I am attempting to write a sudoku solver in Mathematica just to see if I can do it. I really should get a book of these before the next trip that I take.

In one of my classes that I don't really have to pay attention in my friend and I do Sudokus. I print out a few every class. We can generally get through 2 mediums and 1-2 hards in 50 minutes. But we're always interuppted by having to take notes.

Heh, I should write a sudoku-solver in prolog. The "dumb" method might take a decent bit of computer time -- even a few seconds -- but I bet there's a way to make it a pretty darn smart solver.

If anyone gets "Games" magazine, they teach you how to create your own Suduko this month. (The Holiday issue)

Right off the way I would do it is make an 2d array of all the slots. Fill the known numbers. Then iterate through each slot and figure out the numbers that are possible for the slot. The possible numbers fill the 2nd d. When the 2nd d only has 1 value, then that slot is solved.

human: prolog is a logic language. I wouldn't need to make any sort of array, I'd just tell it the victory conditions and current layout. Prolog, just by how it works, would keep trying all possible combinations until it fulfilled the victory conditions (and due to how prolog and sudoku both work, this would happen along a somewhat efficient path). However, there are more efficient ways.
I suspect there are better ways than your way, as well.
