A point is scored when one team is throwing the ball against the tchoukball net and the returning ball hits the floor.
It is a very fair sport so it is not allowed to catch a pass of the enemy team, to take the ball of an enemy plazer or to disturb them by throwing the ball at the net.
The defense tries only to catch the ball when it is returning from the shot.
Also there is a zone around each net that doesn't count to the field. Every player with the ball needs to be inside the field. Also a point can only be scored inside the field.
If a rule is broken the other team gets the ball.
The last special thing about tchoukball is, that it is possible to attack on both sides - both nets are available for both teams.
