If you are unable to view the video, here are the rules of the game:
The first player names a 'score' and this is the total that both players try to reach.
The second player places a counter on the board over one of the numbers and says that number.
The first player moves the same counter in any direction along a line segment to a neighbouring number and announces the total of the two numbers.
The second player moves the same counter to cover a neighbouring number, adds on that number, and announces the total of the three numbers.
The players take it in turns to slide the counter to cover a neighbouring number and to add that number to the total. The players must move when it is their turn and no 'jumping' is allowed.
The winner is the player who makes the total to be exactly equal to the 'score' declared at the start. Making the total go above the 'score' loses the game.
