Once again it is Thursday, so time for the second-hardest (or second-easiest) sudoku of the week. I guess it depends on whether you're a "cup is half-full" or a "cup is half-empty" kind of person.

The rules of sudoku: The puzzle board consists of a 9 by 9 grid, which is further divided up into nine 3 by 3 blocks. In each row, column, and 3x3 block, the numbers 1 through 9 each get written exactly once. The puzzle board generally starts with 18 to 30 of the cells in the grid already filled in. For those who need help, a short tutorial on how to solve sudoku puzzles can be found here.

To solve this puzzle, I suggest first saving the GIF on your computer. Then print it out and solve it in pencil (or in pen if you're feeling bold), or if you don't feel like using paper, then solve it using a graphics editor such as Microsoft Paint.

If you solve this puzzle, time yourself and put your time in the comments. I will be posting the solution in a day or two.

Update: the solution is here.
