How to play
You make the first move. Make a legal Sudoku move: a number from 1 to 4 so that you don't put the same number in a single row, column, or cluster. If a move isn't legal, that move is blocked and you can't make it. Certain moves will block other moves, so try to be the last one to make a legal move!
Where does Duidoku come from?
The original idea comes from Cornell University professor of Economics Kaushik Basu. As for the name,
dui comes from the word meaning
two in Sanskrit, so
Duidoku is a two-player version of Sudoku!
