Player One starts by putting a paper clip over two numbers in the row below the board.
He/She multiplies the numbers and covers that answer on the board with a counter of their chosen colour. Player Two moves only one paper clip to a new number in the row beneath the board. He/She multiplies the paper clip numbers together and covers that answer on the board with a counter of their chosen colour. Play continues like that until one player has four of their counters in a row vertically, horizontally, or diagonally. They are the winner. If the answer to multiplying two paper clip numbers is already covered the player loses that turn.
