when the player is held by one or more opposing players and the ball or the hand or arm holding the ball comes into contact with the ground. An attacking team gets a maximum of six tackles to progress up the field before possession is changed over. Once the tackle is completed, the ball-carrier must be allowed to get to his feet to 'play-the-ball'. Ball control is also important in rugby league, as a fumble of the ball on the ground forces a handover, unless the ball is fumbled backwards. The ball can also be turned over by going over the sideline. Comparison with rugby union Rugby league and rugby union are distinct sports with many similarities and a shared origin. Both have the same fundamental rules, are played for 80 minutes and feature an oval-shaped ball and H-shaped goalposts. Both have rules that the ball cannot be passed forward, and dropping it forwards leads to a scrum. Both use tries as the central scoring method and conversion kicks, penalty goals and drop goals as additional scoring methods. However, there are differences in how many points each method is worth. One of the main differences is the rules of possession. When the ball goes into touch, possession in rugby union is contested through a line-out, while in rugby league a scrum restarts play. The lesser focus on contesting possession means that play focuses more on powerful running, hard tackling, forward progression and the contest for field position (commonly compared to an "arm wrestle"); as a result play stops much less frequently in rugby league, with the ball typically in play for 50 out of the 80 minutes compared to around 35 minutes for professional rugby union. Other differences include that there are fewer players in rugby league (13 compared to 15) and different rules for tackling. Rugby union has more detailed rules than rugby league and has changed less since the 1895 schism. Since rugby union turned professional in the mid-1990s, it has increasingly borrowed techniques, tactics and even laws from rugby league, while high profile players and coaches from the league game have increasingly gone on to success in the union code in those countries where both codes are popular (e.g. Andy Farrell, Jason Robinson and Henry Paul). The inherent similarities between rugby league and rugby union have at times led to experimental hybrid games being played that use
