In compliance with the law, the gambling is for prizes rather than money and, since 'yugi' (the games) are based on archery, which is a skill, they are written with the characters for 'play' and 'skill' rather than the usual 'play' and 'fun' and classified differently from the 'tomikuji,' which is a lottery based on pure chance.
また法律の成立においても懸け物の的場（景品交換式遊技場）が基本にあるので、「遊技」と言う言葉が「遊戯」ではないのは、弓矢は技術が伴う事に由来し、法律の根拠としても偶然性のみのくじ引きである、「富くじ（宝くじ）」との区別の根拠となっている。
