<P> While Rounders England and GAA codes differ, they share much in common . </P> <P> The bowler, or' feeder', bowls the ball with an underarm pendulum action to the batter . According to Rounders England rules, the ball is deemed a' good' ball if it passes within reach on the striking side between the batter's knees and the top of the head . Otherwise, it is called a' no - ball' or' bad' ball . The ball is also regarded as bad if it is thrown into the batter's body or wide of the batting box . A batter may try to hit a bad ball but is not required to do so . A player is not out if a no - ball is caught and cannot be called out on first base . </P> <P> When a batter leaves the post, each runner on a base may run to the next and succeeding base . A post runner cannot be declared out when standing at a base . The batter must keep in contact with the base to avoid being declared out . A rounder is scored if one of the batting team completes a circuit without being out . The Rounders England rules state that a half rounder is scored if half a circuit is completed by a player without being put out, or if the batter has not hit the ball but makes it all the way to the fourth base . A batter is out if a fielder catches the ball cleanly; the batter reaches a base that had been' stumped' (touched while holding the ball) by a fielder; the bat is dropped whilst the batter is running; the batter leaves the base before the bowler has bowled the ball; or the batter is' run out' (overtaken) by the next batter . </P> <P> In the United Kingdom, the rules of rounders are regulated by Rounders England . Games played under these rules use smaller bats and balls and are played on a smaller pitch compared to GAA games . The bases are marked with posts, which batters must keep in contact with and fielders must' stump', and only one' good' ball needs to be thrown before a batter must run .' Half - rounders' are also counted in scoring . </P>
