I go through phases where I’m hooked on sudoku, and I’m in a bit of an ‘on’ phase at the moment. However, I’ve been doing the same sudoku puzzle for about 3 hours now and am getting increasingly frustrated because I’ve only filled in about 9 numbers so far.
This particular grid is 16 x 16 with the numbers 0-9 and letters A-F. It’s a tad difficult. This normally makes me all the more determined to solve it, but I have a sneaking suspicion that this one is going to beat me.
If I stick to my usual rule of not going to bed until it’s finished, I won’t be going until 2008 at the earliest. I’ll have give up in a minute otherwise I’ll have that annoying thing where you can’t sleep because everytime you close your eyes you see a sudoku grid with all the numbers dancing around.
Perhaps this little guy can give me a hand?
How does my garden grow? 
I’ve definitely had moments of Sudoku craziness – I haven’t done one in a while, though (although I tried, and failed, yesterday morning)
