Alphaeus Ang is no ordinary 11-year-old boy.
The Year 7 pupil at Liston College in Henderson was yesterday named the New Zealand sudoku champion at the inaugural New Zealand Festival of Mindsports in Thames.
As well as the sudoku title, the Aucklander also won the draughts competition and placed second in the chess tournament, only beaten in a play-off against 57-year-old former national champion Bob Smith.
Alphaeus picked up four gold medals and one silver, with most of his competitors many times his age.
For some, like his father, Keong Ang, Alphaeus' talents are not surprising.
