This version of Colour Sudoku (which is intended for demonstration purposes and only implements a small subset of the interactions supported by the EM version) was developed by Antony Harfield in connection with his doctoral thesis EM as a new paradigm for educational technology. Another strategy for solving is experimenting with the colour assigned to the digit.Ĭolour Sudoku is a by-product of research into computing support for education carried out by the Empirical Modelling Research Group at the University of Warwick. The colours that are assigned to the digits can be changed from the panel on the right-hand side. If a black square is encountered then a mistake has been made (assuming no digits are assigned to black).An empty square that has the same colour as a completed square must contain the same digit.Darker coloured empty squares imply fewer possibilities.The empty square's colour is the combination of the colours assigned to each plausible digit. Empty squares are coloured according to which digits are plausible taking account of all current entries in the square's row, column and region. Squares containing a digit are coloured according to the digit's colour. To remove a digit, move the mouse pointer over a square and press the spacebar on the keyboard.Ĭolour sudoku adds another dimension to solving by assigning a colour to each digit.To insert a digit into a square, move the mouse pointer over a square and use the keyboard to type a number into the square.The aim of Sudoku is to fill the grid with the digits 1 to 9 in such a way that each digit occurs exactly once in each row, column and region: The Colour Sudoku application requires the Adobe Flash Player version 9 or newer.
