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!
