He/she must apply to the SUDOKU rule that inat inside each row, each column and each block a digit may appear only once. When the first player made his/her move, the next player places his/her cardboard piece on the board - of course, remembering about sudoku rule. The hourglass limits the length of turn. If the hourglass becomes empty and the player has not placed his/her cardboard piece yet, he/she misses his/her chance and it is the next [;ayer's turn.
