There's a classic Soviet film by Pudovkin titled Chess Fever!. The hero goes mad for playing chess.
Well, someone I know is addicted to Sudoku, plays it day and night--in newspapers, online, wherever. And while I was at Borders today, I noticed a wall chock full of Sudoku books.
Apparently, Sudoku is like a crossword puzzle, but with numbers in a sequence instead of witty word clues. And the puzzles are made by machines, instead of people.
It seems to be as addictive as computer solitaire, too...
