LONDON: A newer version of Google can now solve the math puzzle Sudoku - no matter how difficult it is.

A newly updated mobile phone application, called Google Goggles, uses a phone's camera to capture a picture of any Sudoku puzzle and then sends it back to Google.

The servers at Google compute the answer and send back the image to the user.

Phil McNeill, the Daily Telegraph's Puzzles Editor said the move was "a sad day" for puzzle fans.

"When you finally solve a real mind-bender, it brings a rush of achievement. I hope Google's new tool won't diminish that feeling," the Telegraph quoted him as saying.

The application's main function, however, is for price comparison information and general web searching.

Goggles is available on the iPhone and all Google Android phones.
