I don't even know if sudoku-ing is a real word but it best describes what we've been doing. Ever since I began doing it a few months ago I've known that with me it's not a passing fad. And everywhere Sudoku madness is evdient. It's in the Metro and the City AM so I can keep myself occupied in the tube. Bookshelves stock paperbacks from every publisher, with celebrity endorsements and to suit every level of difficulty. There are competitions in local clubs.
As if that were not enough there are newer crazes: killer sudoku, kakuro, other odd sounding games.
I'm still hooked on sudoku though. It's my crossword puzzle. I've consistantly been racing against the clock and finishing the daily puzzle on Fingertime. I'm getting better and better at it. My best ever time is 4:33 although my average is still 6 mins.
