In short: a very well-known game in which playing together and running free is central.
Organisation: Two teams of three to five players in a space delimited by pylons of about 20 by 20 metres (on the field somewhat larger). Ten-ball is a game of which I have the idea, that it is more popular with Party 1 has the ball and has to try to play 10 times together than with players: sitting in front without the other party intercepting the ball. If it fails, then most korfball players are not enough, it is party 2's turn. If they do succeed in playing 10 times together, then they get the challenge. Make the challenge therefore play together, then party 1 gets a point and party 2 may try to play 10 times together, etc. Which side gets the most points? make it more difficult with for example the following variations:
1 ) If the ball is touched by the defending side, then the attacking side is also 'off'.
2 ) Make the playing field small: combining in an area of 10 by 10 is significantly more difficult than playing together in an area of 30 by 30 meters.
3 ) Increase the number of times to combine: for seniors, 50 times should not be a problem either (it usually is, by the way!).
4 ) Just ten ball, with the understanding that the ball may not be played back to the person from whom it was received.
