What defines a 'toucher' in the game?

In the game of Bowls, a 'toucher' is specifically defined as a bowl that makes contact with the jack while in motion. This is an important concept because a toucher holds certain advantages during play. For instance, if a bowl is declared a toucher, it remains in play even if it subsequently lands in the ditch, provided it initially made contact with the jack. This rule adds a strategic layer to the game, as players aim for their bowls to touch the jack to keep them actively influencing the end.

In contrast, the other definitions provided do not accurately capture the essence of what constitutes a toucher. A bowl that hits the jack and stops in the ditch, while it can be exciting, would not be considered a toucher unless it touched the jack before settling. Likewise, a bowl that only comes into contact with the jack after it has stopped is not recognized as a toucher because the action of touching must occur during its delivery. Finally, a bowl that is delivered with the wrong bias does not pertain to the idea of a toucher because it does not involve contact with the jack at all, making it irrelevant to the definition of a toucher in the context of the game's rules.
