Complete a number grid using the values already on the board.
How to play
Pick an empty cell and choose a number that fits its row, column and box. Read the grid before using the number picker.
Tips and strategies
Start with rows, columns or boxes that already contain most numbers. When a cell could take several values, leave it and look for a definite placement elsewhere.
Before committing, check what space the move leaves for the next piece or action.
