This game was made using Notepad that comes free with Windows. The objective
is to turn all the dark red squares to white squares. Any square you click will
alternate its colour and the colour of the 8 surrounding it.
If you wish to play on a larger grid, add a ? mark to the end of the
webaddress followed by the size of grid you want.
e.g. http://pottsy.awardspace.co.uk/grid.html?6 would give a 6x6 grid
