''Colour Sudoku'' is the new craze among Sudoku lovers

London, Dec 18 (UNI) Bored of that black and white sudoku in newspapers! Play the coloured and innovative sudoku on computers now.

A colourful new way to make Sudoku more addictive, and easier, has come from scientists who are trying to make computers more creative, the Daily Telegraph reported today.

''Colour Sudoku'' was invented by a doctoral student at the University of Warwick in his research on how to use computers to show the complicated alternatives on offer to help solve a complicated problem, Mr Antony Harfield said that this spin out from his research seems to have caught the imagination of those already caught up with the Sudoku craze.

''This was the application that people got most excited about,'' Mr Harfield said.

The colour Sudoku adds another dimension to the game by assigning a colour to each digit, taking advantage of how the human eye is quick to absorb information about colour and patterns.

''It can speed things up,'' he added.

Dr Steve Russ of the Empirical Modelling group at the University of Warwick said: ''Even in something so simple as a Sudoku puzzle humans use a mixture of perception, expectation, experience and logic that is just incompatible with the way a computer program would typically solve the puzzle.''
