Sudoku has been a hit for years but I never really catch on until I move to a new company.
In my current workplace, one of our favourite pastime is playing crossword puzzles on the free Metro paper. However my interest in crossword quickly fades as words like "ERR" appear in the crossword solution - what kind of word is "ERR"? So my attention gradually shifts to Sudoku, and I must say it is pretty addictive. Now a day can't pass without a few games of Sudoku.
Here's a great site for some free Sudoku:
