there are two methods of game , tekichu-sei (the accuracy system ) and tokuten-sei (the point system ). 的中制と得点制がある。
operators of privately owned taxis are often given refunds from tax payments including the consumption tax because the business operator tax exemption point system based on the consumption tax act applies to them (since their sales are less than the prescribed value ); therefore , the fare of privately owned taxis is set lower than that of corporate taxis . 個人タクシーでは消費税法に基づく事業者免税点制度が適用されることから（売り上げが規定値以下のため）消費税の納税義務を免除されており、その分、個人タクシー「個人タクシー」と「法人タクシー」よりも運賃が安くなっている。
recently , match rules have been revised to a great extent: the introduction of the point system that makes game judgment more sport-like than before , the use of different colors for wrist guards (blue and red , where previously both players wore white wrist guards and a red belt was used to distinguish a red player from a white player ), and--in a more minute aspect--changes in the numbers and standing positions of referees . 近年では、勝負の判定を従来よりスポーツライクなものとしたポイント制や、拳サポーターの色分け（青と赤、従来は両者が白で、赤と白の区別は赤帯を用いていた）、細かなものでは審判の人数や立ち位置など、ルールにかなりの見直しが施されている。
