Sudoku

Margaret started playing Sudoku on her phone when we were on holiday last month. She then discovered that the same software was on my iPad and has been playing almost every day since we returned, gradually improving her game.

Today, she has just produced her best time for a game so far.

There's still another 3% to go though!

(By the way - she says that it is very difficult to get such a high score on a "Simple" game.)
