2017/18 Rules Revision Summary
Before the start of the game
.Place one snowball case (90 pcs) behind the Chateau. Players are to line up in front of the backline holding snowballs. The game begins when the referee blows the whistle.
In order to attack and, at the same time, prevent attacks from opponents, it's best to capture the shelter closest to the opponents (see chart above).
Fast balls are not the only method of attack. Lobs are effective in attacking opponents hidden behind shelters. One effective strategy is to have multiple teammates targeting a single opponent.
According to the rule, forward players are not allow to go behind the backline of their own court. Only backcourt players are allow to supply the snowballs from the case behind the Chateau. Generally, the method of supplying snowballs are either by rolling or by passing from hand-to-hand. (Toss passes are not allowed.)
