Dead Jack Meaning in Lawn Bowls

Dead jack describes a jack that becomes invalid during an end. Specific rule situations cause officials to declare the jack dead. When the jack leaves the rink boundary it becomes dead immediately. Contact that pushes the jack completely outside play also creates a dead jack. Some rule sets also declare dead jack after unusual interference events. Once declared dead the current end normally stops immediately. Players then prepare to restart the end from the beginning. All previously delivered bowls no longer influence scoring outcomes. Officials return the jack to the mat area for another delivery. Teams repeat the same order of play for the restarted end. Accurate control usually prevents accidental jack removal from the rink. Players often guard the jack to avoid powerful attacking shots. Skips evaluate risk before calling strong displacement attempts. During one end a bowl strikes the jack forcefully forward. The jack rolls completely beyond the back boundary line. Officials immediately declare the jack dead and stop play. Both teams collect bowls and prepare to replay the end. Tactical planning resumes once the jack returns to the mat. Players often deliver gentler weight when jack position looks vulnerable. Careful placement reduces chances of jack removal from play. Green awareness helps bowlers judge safe striking angles. Understanding dead jack rules helps beginners follow sudden end restarts. Accurate observation ensures players react correctly after jack movement. Dead jack situations maintain fairness when the target leaves the rink.
