sudoku II

i'm seriously addicted to sudoku. it is a japanese number game that comes in easy, medium, and hard. i've never heard of it until i came here. our electrical TA found it in the newspaper the hotel sets in front of our door that i stepped over daily. once i found it, i was hooked. my brain has been atrophying here, and this is one thing to help me not drool on myself once i get back to civilization. so i found a sudoku you can put in your page, so i did, it is there on the left. try it out. using it is simple, click in the box, put in the number.

DIRECTIONS:
the concept is rather simple. there are nine rows, nine columns, and nine 3x3 boxes. in each row, column, and 3x3 box you need to have the numbers 1-9 without repeating. that's it.

fun fun fun. give it a try. tell me what you think about it. you can change the difficulty as well. sudoku rocks.
