team fails to complete two passes in four downs), an interception occurs, or the team on offense scores a touchdown. Touchdowns are worth 6, 7, or 1 point(s) depending on the rules set out before the game. In some instances, depending on the width of the field more downs are used or teams are given a certain number of downs to score in as opposed to 4 tries to get a first down. For instance, a team might be given 8 tries to score and advance the ball from where they receive the ball or establish position. Also the length of a first down may differ due to the lack of a pass rush. For instance, a team may have to advance fifteen or twenty yards to get a first down in 4 tries. Field goals and extra point kicks are nonexistent (streets and backyards have no goal posts), although punts can frequently happen, usually during "4th and 2 completions" situations where the offensive team cannot earn a first down. (In games played on regulation fields, these kicks can be attempted, but only in certain scoring systems.) In the event a touchdown is scored, the team on offense will normally stay in the end zone in which they had just scored and the other team will go into the main field and field the subsequent kickoff. This rule is some times known as "losers walk". Thus, until an interception or turnover on downs, both teams defend and attempt to score on the same end zone. Rules greatly vary from neighborhood to neighborhood and are customarily set before each game. There can be a rush on the QB depending on the rules set out before the game. Usually if rushes are allowed, there are 2 rules that are commonly applied: call rush and blitz count. Call rush is the first rule of rushing the QB in street. This is where the defense calls "Blitz" in a loud voice before the offense hikes the ball, signifying that they will rush, but there is also a counter effect with this. The QB can get out of the pocket and run without having to pass or hand off the ball, also the quarterback can call "shotgun" before or after the other team says "blitz" causing the opposite to have to count to 5 or 10 depending on whether or not they called blitz 5
