You have remember Shunsui himself is told the rules that he also has to follow. The devastating aspect is that it takes child games and makes them deadly. Its a nicer variation of the saw movies. We yet know how many can be involved but one thing that doesn't change is battle. It makes rules to battle by. Its a warped version of the rules of engagement. Some abilities are direct with other zanpakuto while Katen Kyokatsu puts both combatants in a situation determined by cunning and skill that it itself dictates. We have yet to see what other games it has either so we don't know if its just one on one combat or if more can be involved. Its interesting cause a fight can go either way depending on who plays the game better. This puts most fights on even terms even with strong combatants the concept is whether or not they know the rules of the game. Katen Kyokatsu herselves make determines the game and each game apparently has a predetermined set of rules. Shunsui apparently has to go along just like his opponent.
