The parlay rule is an important concept in airsoft. It is a set of guidelines that players must abide by during a game to ensure fair play. In essence, the parlay rule requires that players make an effort to engage in combat at a safe distance before shooting. If two players encounter each other face to face at a distance that is too close to shoot, one or both can call parlay to alert other players that they are in an unsafe shooting situation. Once called, the players must both retreat along the route they came from to a safe distance before trying to shoot one another. Many airsoft fields have minimum engagement distances like 15 feet, so opposing players who are at closer distances like 5 or 10 feet away should use the parlay rule. Also, the players should both have the same tactical advantage meaning one was not going to surprise another. If one player did have the advantage another rule like the bang bang rule may come in to play. The other players must cease fire during a parlay and not use the time to reposition or advance in an unfair way. This rule helps to ensure that all players are playing fairly and that no one is taking advantage of their opponents. It also prevents any unnecessary injuries from occurring due to careless or malicious shooting. Following the parlay rule is essential for a safe and enjoyable airsoft experience for everyone involved.
