NEW DELHI  The latest bane of office productivity is Scrabulous, a virtual knockoff of the Scrabble board game, with over 700,000 players a day and nearly three million registered users.

Fans of the game are obsessive. They play against friends, co-workers, family members and strangers, and many have several games going at once.

Everyone seems to love the online game  everyone, that is, except the companies that own the rights to Scrabble: Hasbro, which sells it in North America, and Mattel, which markets it everywhere else.

In January, they denounced Scrabulous as piracy and threatened legal action against its creators, two brothers in Calcutta named Rajat and Jayant Agarwalla who run a software development company. Both Hasbro and Mattel said they were hoping for a solution that would not force them to shut down the game.
