Bogglific, an online version of Boggle, has been taken down from the social networking site.
The move comes after the game’s creator Roger Nesbitt, was forwarded a cease and desist letter allegedly by Hasbro.
The letter posted on Facebook said: “Simply put, it is illegal and Hasbro has an obligation to protect its Boggle brand.”
But Nesbitt believes Hasbro’s claims are unfounded.
“They claimed that I breached their copyright. US copyright quite clearly claims that you cannot copyright the logistics of the game,” he said.
He says Bogglific provides Hasbro with free advertising and that he hasn’t made any money from the game. He plans to launch a similar word game soon.
Scrabulous, the first game targeted by Hasbro for breach of copyright, still remains on Facebook.
