century, the option of snapping the ball back by hand was added. The option to play the ball with the foot was preserved, however, for several decades, although by early in the 20th century it was restricted to kicking the ball forward. The kick forward in scrimmage was a surprise play that did not work against a prepared defense. Also for several decades alternatives to the scrimmage for playing the ball from across the sideline after it had gone out of bounds—a throw-in or "fair", and "bounding in"—existed. Until well into the 20th century, rather than an official readying the ball for scrimmage, the side entitled to the snap had complete custody of the ball and could snap it from the required spot at any time; for instance, a tackled ball carrier might feign injury, then suddenly snap the ball while recumbent, there being no stance requirement yet. The neutral zone and the right of the center not to be contacted by an opponent before the snap also was not an original feature. As the 20th century drew to a close, the NCAA and National Federation of State High School Associations extended that protection to some time
238:, the line of scrimmage of the team without the ball is 1 yard past their side of the ball. The player snapping the ball (known officially as the "snapper" in rule books) delivers the ball to another player, and that action is the snap. The snapper may hand, throw, or even roll the ball to the other player. The snap must be a quick and continuous movement of the ball by one or both hands of the snapper, and the ball must leave the snapper's hands. The various rules codes have additional requirements, all of which have the effect of requiring the ball to go backward. The snapper almost always passes the ball between his legs, but only in Canadian football is that required. 285: 133: 443: 324: 166: 36: 219: 539:
years after the adoption of the hand snap, a hand-to-hand snap was illegal, the ball required to be thrown instead, in Canadian football. (Though it was technically legal, the hand-to-hand snap was not used on the American side of the border until the 1930s.) Apparently, a complete break was desired from system of backheeling, and the

It is easier to predict when the ball will be snapped with 2 seconds left on the play clock, rather than 5 seconds. 538:
led to the three-man scrimmage being reduced to the centre alone, the number of players on the field being reduced commensurately from 14 to 12, and a snap rule and neutral zone similar to that of American football was adopted. In addition to the between-the-legs requirement noted above, for several

The rule adopted by a committee for American football in 1880 first provided for the uncontested right of one side to play the ball by foot (in any direction) for a scrimmage. A certain use of the foot on the ball which had the same effect as heeling it back was known as a "snap". Later in the 19th

The game design rationale for requiring the snap to be a quick and continuous motion to the backfield is to eliminate the need for rules provisions for a live ball in scrimmage. In rugby union the ball may be retained by the forwards and played for a time via the foot in a scrummage (which rugby

The team entitled to snap the ball will usually know in advance the moment when the snap is to occur as one of their players calls out signals, which usually include a loud sound such as "hut" voiced one or more times, the number of which they know; they are thus said to know the "snap count".

The defensive team is not allowed to simulate, by calling out numbers, the offense's snap count. Successfully simulating the count would cause members of the offensive team to act too early ruining co-ordination of the play and inviting penalties. Current rules, unlike earlier rules, position
