Sudoku
http://en.wikipedia.org/wiki/Sudoku
It's been around for about 20 years but only recently become popular in the UK. I like it because it goes back to basics. No computers, fancy hand held device needed. Just good old fashion pen and paper. I am no fan of crossword puzzles, but I am now totally addicted to Sudoku. I was surprised to find no results on the TFP search!
Anyway, all I can say is try it. Goto the wikipedia web link above. Read about the basic rules, and then try doing a Sudoku puzzle.
