I started about the middle of January 2010.
I first took about 45 minutes to complete the EASY level. Slowly, this time reduced to about 15 minutes. The MIDDLE level was then achieved, again in about 20 minutes. I was never able to complete the DIFFICULT level, usually getting to about 30% and then giving up.

Today, after 3 months, I completed all three levels in one sitting. The total time taken was 75 minutes.
Now that my primary objective has been achieved, I realised that my brain cells were actually not functioning as they should. The confidence this has given me is so immense that I feel am not quite a doddering old man.
I will now try to achieve the higher level by trying to complete all three levels in 15 minutes. It may take me a year to get to this level - so stay tuned! I will shout it from the blogtops when I get there!
Thank you Bina!
Well done Sudoku, and whoever invented this!
