I usually do a couple before I go to bed out of a little $1 book of them that I've got. It gives me time to get out from in front of the computer monitor long enough to start getting sleepy.
I dont like sudoku, i will stick with crosswords. suduko are boring cuz anyone who can see can solve them. now this made it even more boring.
I still love playing Sudoku. Just a puzzle in a day and Keep your mind busy and this is what I love most.
I used to like playing Sudoku and may be was rather addicted to it. But one time I've continued all the levels and my interest to this game fell down.
