To play this game, you just need to screw a piece of paper up into a ball and you’re off. You can score goals, follow the course or hit the targets. Make up your own rules: there can be one or several players... The book can be stood up or laid down on a table, or you can hang it up… You can throw the ball, flick it, use a rubber band to shoot it or use the detachable piece of board to help perfect your aim. Have fun, but beware, grown-ups have been known to borrow this game and even to take it to work, so keep your eye on it!
