Elizabeth Hurley is frustrated by puzzles.

The model-and-actress has recently started challenging herself again with games of Sudoku - a logic-based number placement puzzle - after taking a break from the popular brain-teaser, but admits she is struggling to solve the challenges.

She wrote on her twitter page: "Having just taken up Suduko again, after 2 yr lull, I find I can't do it any more ... I used to do Fiendish, now struggling with Mild. Help!!

"Have been staring at the same puzzle for over an hour . am completely stuck."

Hurley has been playing Sudoku again while on holiday in India.

The 45-year-old beauty - who is married to Indian businessman Arun Nayar and has an eight-year-old son Damian from a previous relationship - landed in the country on Saturday (23.10.10) and is having a great time.

She added in other tweets: "Landed, India-very humid and drops of rain. Still feels like end of monsoon. But so happy not to be shivering . Great day in Bombay - lots of shopping and lots of eating."
