But its fan base extends far beyond the math geeks among us to those somewhat literary types who are uncertain how fast they can add or subtract let alone multiply or divide under pressure.

"I am not a puzzler," said Fuhrer, 55, from his Pleasantville office of Nextoy, a toy business known for Airblade from Mattel and Gator Golf from Hasbro Games.
But he, his family and friends and thousands of others do KenKen puzzles.
They can't seem to put these KenKen squares down. Which is good for newspapers, such as the Times of London and The New York Times, that print them alongside the venerable crosswords. And good for KenKen book publishers, a website and iPhone app that Fuhrer, who holds the trademark, feeds.
